Paradigms All The Way Down

Related to: Book Review: The Structure Of Scientific Revolutions

Every good conspiracy theorist needs their own Grand Unified Chart; I’m a particular fan of this one. So far, my own Grand Unified Chart looks like this:

Philosophy Of Science Paradigm Anomaly Data
Bayesian Probability Prior KL-divergence Evidence
Psychology Prediction Surprisal Sense-Data
Discourse Ideology Cognitive Dissonance Facts
Society Frames & Narratives Exclusion Lived Experience
Neuroscience NMDA Dopamine AMPA

All of these are examples of interpreting the world through a combination of pre-existing ideas what the world should be like (first column), plus actually experiencing the world (last column). In all of them, the world is too confusing and permits too many different interpretations to understand directly. You wouldn’t even know where to start gathering more knowledge. So you take all of your pre-existing ideas (which you’ve gotten from somewhere) and interpret everything as behaving the way your pre-existing ideas tell you they will. Then as you gradually gather discrepancies between what you expected and what you get (middle column), you gradually become more and more confused until your existing categories buckle under the strain and you generate a new and self-consistent set of pre-existing ideas to see the world through, and then the process begins again.

All of these domains share an idea that the interaction between facts and theories is bidirectional. Your facts may eventually determine what theory you have. But your theory also determines what facts you see and notice. Nor do contradictory facts immediately change a theory. The process of theory change is complicated, fiercely resisted by hard-to-describe factors, and based on some sort of idea of global tension that can’t be directly reduced to any specific contradiction.

(I linked the Discourse and Society levels of the chart to this post where I jokingly sum up the process of convincing someone as “First they ignore you, then they laugh at you, then they fight you, then they fight you half-heartedly, then they’re neutral, then they grudgingly say you might have a point even though you’re annoying, then they say on balance you’re mostly right although you ignore some of the most important facets of the issue, then you win.” My point is that ideological change – most dramatically religious conversion, but also Republicans becoming Democrats and vice versa – doesn’t look like you “debunking” one of their facts and them admitting you are right. It is less like Popperian falsification and more like a Kuhnian paradigm shift or a Yudkowskian crisis of faith.)

Why do all of these areas share this same structure? I think because it’s built into basic algorithms that the brain uses for almost everything (see the Psychology and Neuroscience links above). And that in turn is because it’s just factually the most effective way to do epistemology, a little like asking “why does so much cryptography use prime numbers”.

Book Review: The Structure Of Scientific Revolutions

When I hear scientists talk about Thomas Kuhn, he sounds very reasonable. Scientists have theories that guide their work. Sometimes they run into things their theories can’t explain. Then some genius develops a new theory, and scientists are guided by that one. So the cycle repeats, knowledge gained with every step.

When I hear philosophers talk about Thomas Kuhn, he sounds like a madman. There is no such thing as ground-level truth! Only theory! No objective sense-data! Only theory! No basis for accepting or rejecting any theory over any other! Only theory! No scientists! Only theories, wearing lab coats and fake beards, hoping nobody will notice the charade!

I decided to read Kuhn’s The Structure Of Scientific Revolutions in order to understand this better. Having finished, I have come to a conclusion: yup, I can see why this book causes so much confusion.

At first Kuhn’s thesis appears simple, maybe even obvious. I found myself worrying at times that he was knocking down a straw man, although of course we have to read the history of philosophy backwards and remember that Kuhn may already be in the water supply, so to speak. He argues against a simplistic view of science in which it is merely the gradual accumulation of facts. So Aristotle discovered a few true facts, Galileo added a few more on, then Newton discovered a few more, and now we have very many facts indeed.

In this model, good science cannot disagree with other good science. You’re either wrong – as various pseudoscientists and failed scientists have been throughout history, positing false ideas like “the brain is only there to cool the blood” or “the sun orbits the earth”. Or you’re right, your ideas are enshrined in the Sacristry Of Settled Science, and your facts join the accumulated store that passes through the ages.

Simple-version-of-Kuhn says this isn’t true. Science isn’t just facts. It’s paradigms – whole ways of looking at the world. Without a paradigm, scientists wouldn’t know what facts to gather, how to collect them, or what to do with them once they had them. With a paradigm, scientists gather and process facts in the ways the paradigm suggests (“normal science”). Eventually, this process runs into a hitch – apparent contradictions, or things that don’t quite fit predictions, or just a giant ugly mess of epicycles. Some genius develops a new paradigm (“paradigm shift” or “scientific revolution”). Then the process begins again. Facts can be accumulated within a paradigm. And many of the facts accumulated in one paradigm can survive, with only slight translation effort, into a new paradigm. But scientific progress is the story of one relatively-successful and genuinely-scientific effort giving way to a different and contradictory relatively-successful and genuinely-scientific effort. It’s the story of scientists constantly tossing out one another’s work and beginning anew.

This gets awkward because paradigms look a lot like facts. The atomic theory – the current paradigm in a lot of chemistry – looks a lot like the fact “everything is made of atoms and molecules”. But this is only the iceberg’s tip. Once you have atomic theory, chemistry starts looking a lot different. Your first question when confronted with an unknown chemical is “what is the molecular structure?” and you have pretty good ideas for how to figure this out. You are not particularly interested in the surface appearance of chemicals, since you know that iron and silver can look alike but are totally different elements; you may be much more interested in the weight ratio at which two chemicals react (which might seem to the uninitiated like a pretty random and silly thing to care about). If confronted with a gas, you might ask things like “which gas is it?” as opposed to thinking all gases are the same thing, or wondering what it would even mean for two gases to be different. You can even think things like “this is a mixture of two different types of gas” without agonizing about how a perfectly uniform substance can be a mixture of anything. If someone asks you “How noble and close to God would say this chemical sample is?” you can tell them that this is not really a legitimate chemical question, unless you mean “noble” in the sense of the noble gases. If someone tells you a certain chemical is toxic because toxicity is a fundamental property of its essence, you can tell them that no, it probably has to do with some reaction it causes or fails to cause with chemicals in the body. And if someone tells you that a certain chemical has changed into a different chemical because it got colder, you can tell them that cold might have done something to it, it might even have caused it to react with the air or something, but chemicals don’t change into other chemicals in a fundamental way just because of the temperature. None of these things are obvious. All of them are hard-won discoveries.

A field without paradigms looks like the STEM supremacist’s stereotype of philosophy. There are all kinds of different schools – Kantians, Aristotelians, Lockeans – who all disagree with each other. There may be progress within a school – some Aristotelian may come up with a really cool new Aristotelian way to look at bioethics, and all the other Aristotelians may agree that it’s great – but the field as a whole does not progress. People will talk past one another; the Aristotelian can go on all day about the telos of the embryo, but the utilitarian is just going to ask what the hell a telos is, why anyone would think embryos have one, and how many utils the embryo is bringing people. “Debates” between the Aristotelian and the utilitarian may not be literally impossible, but they are going to have to go all the way to first principles, in a way that never works. Kuhn interestingly dismisses these areas as “the fields where people write books” – if you want to say anything, you might as well address it to a popular audience for all the good other people’s pre-existing knowledge will do you, and you may have to spend hundreds of pages explaining your entire system from the ground up. He throws all the social sciences in this bin – you may read Freud, Skinner, and Beck instead of Aristotle, Locke, and Kant, but it’s the same situation.

A real science is one where everyone agrees on a single paradigm. Newtonianism and Einsteinianism are the same kind of things as Aristotelianism and utilitarianism; but in 1850, everybody believed the former, and in 1950, the latter.

I got confused by this – is Aristotelian philosophy a science? Would it be one if the Aristotelians forced every non-Aristotelian philosopher out of the academy, so that 100% of philosophers fell in line behind Aristotle? I think Kuhn’s answer to this is that it’s telling that Aristotelians haven’t been able to do this (at least not lately); either Aristotle’s theories are too weak, or philosophy too intractable. But all physicists unite behind Einstein in a way that all philosophers cannot behind Aristotle. Because of this, all physicists mean more or less the same thing when they talk about “space” and “time”, and they can work together on explaining these concepts without constantly arguing to each other about what they mean or whether they’re the right way to think about things at all (and a Newtonian and Einsteinian would not be able to do this with each other, any more than an Aristotelian and utilitarian).

So how does science settle on a single paradigm when other fields can’t? Is this the part where we admit it’s because science has objective truth so you can just settle questions with experiments?

This is very much not that part. Kuhn doesn’t think it’s anywhere near that simple, for a few reasons.

First, there is rarely a single experiment that one paradigm fails and another passes. Rather, there are dozens of experiments. One paradigm does better on some, the other paradigm does better on others, and everyone argues over which ones should or shouldn’t count.

For example, one might try to test the Copernican vs. Ptolemaic worldviews by observing the parallax of the fixed stars over the course of a year. Copernicus predicts it should be visible; Ptolemy predicts it shouldn’t be. It isn’t, which means either the Earth is fixed and unmoving, or the stars are unutterably unimaginably immensely impossibly far away. Nobody expected the stars to be that far away, so advantage Ptolemy. Meanwhile, the Copernicans posit far-off stars in order to save their paradigm. What looked like a test to select one paradigm or the other has turned into a wedge pushing the two paradigms even further apart.

What looks like a decisive victory to one side may look like random noise to another. Did you know weird technologically advanced artifacts are sometimes found encased in rocks that our current understanding of geology says are millions of years old? Creationists have no trouble explaining those – the rocks are much younger, and the artifacts were probably planted by nephilim. Evolutionists have no idea how to explain those, and default to things like “the artifacts are hoaxes” or “the miners were really careless and a screw slipped from their pocket into the rock vein while they were mining”. I’m an evolutionist and I agree the artifacts are probably hoaxes or mistakes, even when there is no particular evidence that they are. Meanwhile, probably creationists say that some fossil or other incompatible with creationism is a hoax or a mistake. But that means the “find something predicted by one paradigm but not the other, and then the failed theory comes crashing down” oversimplification doesn’t work. Find something predicted by one paradigm but not the other, and often the proponents of the disadvantaged paradigm can – and should – just shrug and say “whatever”.

In 1870, flat-earther Samuel Rowbotham performed a series of experiments to show the Earth could not be a globe. In the most famous, he placed several flags miles apart along a perfectly straight canal. Then he looked through a telescope and was able to see all of them in a row, even though the furthest should have been hidden by the Earth’s curvature. Having done so, he concluded the Earth was flat, and the spherical-earth paradigm debunked. Alfred Wallace (more famous for pre-empting Darwin on evolution) took up the challenge, and showed that the bending of light rays by atmospheric refraction explained Rowbotham’s result. It turns out that light rays curve downward at a rate equal to the curvature of the Earth’s surface! Luckily for Wallace, refraction was already a known phenomenon; if not, it would have been the same kind of wedge-between-paradigms as the Copernicans having to change the distance to the fixed stars.

It is all nice and well to say “Sure, it looks like your paradigm is right, but once we adjust for this new idea about the distance to the stars / the refraction of light, the evidence actually supports my paradigm”. But the supporters of old paradigms can do that too! The Ptolemaics are rightly mocked for adding epicycle after epicycle until their system gave the right result. But to a hostile observer, positing refraction effects that exactly counterbalance the curvature of the Earth sure looks like adding epicycles. At some point a new paradigm will win out, and its “epicycles” will look like perfectly reasonable adjustments for reality’s surprising amount of detail. And the old paradigm will lose, and its “epicycles” will look like obvious kludges to cover up that it never really worked. Before that happens…well, good luck.

Second, two paradigms may not even address or care about the same questions.

Let’s go back to utilitarianism vs. Aristotelianism. Many people associate utilitarianism with the trolley problem, which is indeed a good way to think about some of the issues involved. It might be tempting for a utilitarian to think of Aristotelian ethics as having some different answer to the trolley problem. Maybe it does, I don’t know. But Aristotle doesn’t talk about how he would solve whatever the 4th-century BC equivalent of the trolley problem was. He talks more about “what is the true meaning of justice?” and stuff like that. While you can twist Aristotle into having an opinion on trolleys, he’s not really optimizing for that. And while you can make utilitarianism have some idea what the true meaning of justice is, it’s not really optimized for that either.

An Aristotelian can say their paradigm is best, because it does a great job explicating all the little types and subtypes of justice. A utilitarian can say their paradigm is best, because it does a great job telling you how to act in various contrived moral dilemmas.

It’s actually even worse than this. The closest thing I can think of to an ancient Greek moral dilemma is the story of Antigone. Antigone’s uncle declares that her traitorous dead brother may not be buried with the proper rites. Antigone is torn between her duty to obey her uncle, and her desire to honor her dead brother. Utilitarianism is…not really designed for this sort of moral dilemma. Is ignoring her family squabbles and trying to cure typhus an option? No?

But then utilitarianism’s problems are deeper than just “comes to a different conclusion than ancient Greek morals would have”. The utilitarian’s job isn’t to change the ancient Greek’s mind about the answer to a certain problem. It’s to convince him to stop caring about basically all the problems he cares about, and care about different problems instead.

Third, two paradigms may disagree on what kind of answers are allowed, or what counts as solving a problem.

Kuhn talks about the 17th century “dormitive potency” discourse. Aristotle tended to explain phenomena by appealing to essences; trees grew because it was “in their nature” to grow. Descartes gets a bad rap for inventing dualism, but this is undeserved – what he was really doing was inventing the concept of “matter” as we understand it, a what-you-see-is-what-you-get kind of stuff with no hidden essences, which responds mechanically to forces (and once you have this idea, you naturally need some other kind of stuff to be the mind). With Cartesian matter firmly in place, everyone made fun of Aristotle for thinking he had “solved” the “why do trees grow?” question by answering “because it is in their nature”, and this climaxed with the playwright Moliere portraying a buffoonish doctor who claimed to have discovered how opium put people to sleep – it was because it had a dormitive potency!

In Aristotle’s view of matter, saying “because it’s their essence” successfully answers questions like “why do trees grow?”. The Cartesian paradigm forbade this kind of answer, and so many previously “solved” problems like why trees grow became mysterious again – a step backwards, sort of. For Descartes, you were only allowed to answer questions if you could explain how purely-mechanical matter smashing against other purely-mechanical matter in a billiard-ball-like way could produce an effect; a more virtuous and Descartes-aware doctor explained opium’s properties by saying opium corpuscles must have a sandpaper-like shape that smooths the neurons!

Then Newton discovered gravity and caused an uproar. Gravity posits no corpuscles jostling other corpuscles. It sounds almost Aristotelian: “It is the nature of matter to attract other matter”. Newton was denounced as trying to smuggle occultism into science. How much do you discount a theory for having occult elements? If some conception of quantum theory predicts the data beautifully, but says matter behaves differently depending on whether someone’s watching it or not, is that okay? What if it says that a certain electron has a 50% chance of being in a certain place, full stop, and there is no conceivable explanation for which of the two possibilities is realized, and you’re not even allowed to ask the question? What if my explanation for dark matter is “invisible gremlins”? How do you figure out when you need to relax your assumptions about what counts as science, versus when somebody is just cheating?

A less dramatic example: Lavoisier’s theory of combustion boasts an ability to explain why some substances gain weight when burned; they are absorbing oxygen from the air. A brilliant example of an anomaly explained, which proves the superiority of combustion theory to other paradigms that cannot account for the phenomenon? No – “things shouldn’t randomly gain weight” comes to us as a principle of the chemical revolution of which Lavoisier was a part:

In the seventeenth century, [an explanation of weight gain] seemed unnecessary to most chemists. If chemical reactions could alter the volume, color, and texture of the ingredients, why should they not alter weight as well? Weight was not always taken to be the measure of quantity of matter. Besides, weight-gain on roasting remained an isolated phenomenon. Most natural bodies (eg wood) lose weight on roasting as the phlogiston theory was later to say they should.

In previous paradigms, weight gain wasn’t even an anomaly to be explained. It was just a perfectly okay thing that might happen. It’s only within the constellation of new methods and rules we learned around Lavoisier’s time, that Lavoisier’s theories solved anything at all.

So how do scientists ever switch paradigms?

Kuhn thinks it’s kind of an ugly process. It starts with exasperation; the old paradigm is clearly inadequate. Progress is stagnating.

Awareness [of the inadequacy of geocentric astronomy] did come. By the thirteenth century Alfonso X could proclaim that if God had consulted him when creating the universe, he would have received good advice. In the sixteenth century, Copernicus’ coworker, Domenico da Novara, held that no system so cumbersome and inaccurate as the Ptolemaic had become could possibly be true of nature. And Copernicus himself wrote in the Preface to the De Revolutionibus that the astronomical tradition he inherited had finally created only a monster.

Then someone proposes a new paradigm. In its original form, it is woefully underspecified, bad at matching reality, and only beats the old paradigm in a few test cases. For whatever reason, a few people jump on board. Sometimes the new paradigm is simply more mathematically elegant, more beautiful. Other times it’s petty things, like a Frenchman invented the old paradigm and a German the new one, and you’re German. Sometimes it’s just that there’s nothing better. These people gradually expand the new paradigm to cover more and more cases. At some point, the new paradigm explains things a little better than the old paradigm. Some of its predictions are spookily good. The old paradigm is never conclusively debunked. But the new paradigm now has enough advantages that more and more people hop on the bandwagon. Gradually the old paradigm becomes a laughingstock, people forget the context in which it ever made sense, and it is remembered only as a bunch of jokes about dormitive potency.

But now that it’s been adopted and expanded and reached the zenith of its power, this is the point at which we can admit it’s objectively better, right?

For a better treatment of this question than I can give, see Samzdat’s Science Cannot Count To Red. But my impression is that Kuhn is not really willing to say this. I think he is of the “all models are wrong, some are useful” camp, thinks of paradigms as models, and would be willing to admit a new paradigm may be more useful than an old one.

Can we separate the fact around which a paradigm is based (like “the Earth orbits the sun”) from the paradigm itself (being a collection of definitions of eg “planet” and “orbit”, ways of thinking, mathematical methods, and rules for what kind of science will and won’t be accepted)? And then say the earth factually orbits the sun, and the paradigm is just a useful tool that shouldn’t be judged objectively? I think Kuhn’s answer is that facts cannot be paradigm-independent. A medieval would not hear “the Earth orbits the sun” and hear the same claim we hear (albeit, in his view wrong). He would, for example, interpret it to mean the Earth was set in a slowly-turning crystal sphere with the sun at its center. Then he might ask – where does the sphere intersect the Earth? How come we can’t see it? Is Marco Polo going to try to travel to China and then hit a huge invisible wall halfway across the Himalayas? And what about gravity? My understanding is the Ptolemaics didn’t believe in gravity as we understand it at all. They believed objects had a natural tendency to seek the center of the universe. So if the sun is more central, why isn’t everything falling into the sun? To a medieval the statement “the Earth orbits the sun” has a bunch of common-sense disproofs everywhere you look. It’s only when attached to the rest of the Copernican paradigm that it starts to make sense.

This impresses me less than it impresses Kuhn. I would say “if you have many false beliefs, then true statements may be confusing in that they seem to imply false statements – but true statements are still objectively true”. Perhaps I am misunderstanding Kuhn’s argument here; the above is an amalgam of various things and not something Kuhn says outright in the book. But whatever his argument, Kuhn is not really willing to say that there are definite paradigm-independent objective facts, at least not without a lot of caveats.

So where is the point at which we admit some things are objectively true and that’s what this whole enterprise rests on?

Kuhn only barely touches on this, in the last page of the book:

Anyone who has followed the argument this far will nevertheless feel the need to ask why the evolutionary process should work. What must nature, including man, be like in order that science be possible at all? Why should scientific communities be able to reach a firm consensus unattainable in other fields? Why should consensus endure across one paradigm change after another? And why should paradigm change invariably produce an instrument more perfect in any sense than those known before? From one point of view those questions, excepting the first, have already been answered. But from another they are as open as they were when this essay began. It is not only the scientific community that must be special. The world of which that community is a part must also possess quite special characteristics, and we are no closer than we were at the start to knowing what these must be. That problem— What must the world be like in order that man may know it?— was not, however, created by this essay. On the contrary, it is as old as science itself, and it remains unanswered. But it need not be answered in this place.

Aaargh! So close!

II.

A lot of the examples above are mine, not Kuhn’s. Some of them even come from philosophy or other nonscientific fields. Shouldn’t I have used the book’s own examples?

Yes. But one of my big complaints about this book is that, for a purported description of How Science Everywhere Is Always Practiced, it really just gives five examples. Ptolemy/Copernicus on astronomy. Alchemy/Dalton on chemistry. Phlogiston/Lavoisier on combustion. Aristotle/Galileo/Newton/Einstein on motion. And ???/Franklin/Coulomb on electricity.

It doesn’t explain any of the examples. If you don’t already know what Coulomb’s contribution to electricity is and what previous ideas he overturned, you’re out of luck. And don’t try looking it up in a book either. Kuhn says that all the books have been written by people so engrossed in the current paradigm that they unconsciously jam past scientists into it, removing all evidence of paradigm shift. This made parts of the book a little beyond my level, since my knowledge of Coulomb begins and ends with “one amp times one second”.

Even saying Kuhn has five examples is giving him too much credit. He usually brings in one of his five per point he’s trying to make, meaning that you never get a really full view of how any of the five examples exactly fit into his system.

And all five examples are from physics. Kuhn says at the beginning that he wished he had time to talk about how his system fits biology, but he doesn’t. He’s unsure whether any of the social sciences are sciences at all, and nothing else even gets mentioned. This means we have to figure out how Kuhn’s theory fits everything from scattershot looks at the history of electricity and astronomy and a few other things. This is pretty hard. For example, consider three scientific papers I’ve looked at on this blog recently:

Cipriani, Ioannidis, et al perform a meta-analysis of antidepressant effect sizes and find that although almost all of them seem to work, amitriptyline works best.

Ceballos, Ehrlich, et al calculate whether more species have become extinct recently than would be expected based on historical background rates; after finding almost 500 extinctions since 1900, they conclude they definitely have.

Terrell et al examine contributions to open source projects and find that men are more likely to be accepted than women when adjusted for some measure of competence they believe is appropriate, suggesting a gender bias.

What paradigm is each of these working from?

You could argue that the antidepressant study is working off of the “biological psychiatry” paradigm, a venerable collection of assumptions that can be profitably contrasted with other paradigms like psychoanalysis. But couldn’t a Hippocratic four-humors physician of a thousand years ago done the same thing? A meta-analysis of the effect sizes of various kinds of leeches for depression? Sure, leeches are different from antidepressants, but it doesn’t look like the belief in biological psychiatry is affecting anything about the research other than the topic. And although the topic is certainly important, Kuhn led me to expect something more profound than that. Maybe the paradigm is evidence-based-medicine itself, the practice of doing RCTs and meta-analyses on things? I think this is a stronger case, but a paradigm completely divorced from the content of what it’s studying is exactly the sort of weird thing that makes me wish Kuhn had included more than five examples.

As for the extinction paper, surely it can be attributed to some chain of thought starting with Cuvier’s catastrophism, passing through Lyell, and continuing on to the current day, based on the idea that the world has changed dramatically over its history and new species can arise and old ones disappear. But is that “the” paradigm of biology, or ecology, or whatever field Ceballos and Lyell are working in? Doesn’t it also depend on the idea of species, a different paradigm starting with Linnaeus and developed by zoologists over the ensuing centuries? It look like it dips into a bunch of different paradigms, but is not wholly within any.

And the open source paper? Is “feminism” a paradigm? But surely this is no different than what would be done to investigate racist biases in open source. Or some right-winger looking for anti-Christian biases in open source. Is the paradigm just “looking for biases in things?”

What about my favorite trivial example, looking both ways when you cross the street so you don’t get hit by a bus? Is it based on a paradigm of motorized transportation? Does it use assumptions like “buses exist” and “roads are there to be crossed”? Was there a paradigm shift between the bad old days of looking one way before crossing, and the exciting new development of looking both ways before crossing? Is this really that much more of a stretch than calling looking for biases in things a paradigm?

Outside the five examples Kuhn gives from the physical sciences, identifying paradigms seems pretty hard – or maybe too easy. Is it all fractal? Are there overarching paradigms like atomic theory, and then lower-level paradigms like organic chemistry, and then tiny subsubparadigms like “how we deal with this one organic compound”? Does every scientific experiment use lots of different paradigms from different traditions and different levels? This is the kind of thing I wish Kuhn’s book answered instead of just talking about Coulumb and Copernicus over and over again.

III.

In conclusion, all of this is about predictive coding.

It’s the same thing. Perception getting guided equally by top-down expectations and bottom-up evidence. Oh, I know what you’re thinking. “There goes Scott again, seeing predictive coding in everything”. And yes. But also, Kuhn does everything short of come out and say “When you guys get around to inventing predictive coding, make sure to notice that’s what I was getting at this whole time.”

Don’t believe me? From the chapter Anomaly And The Emergence Of Scientific Discovery (my emphasis, and for “anomaly”, read “surprisal”):

The characteristics common to the three examples above are characteristic of all discoveries from which new sorts of phenomena emerge. Those characteristics include: the previous awareness of anomaly, the gradual and simultaneous emergence of both observational and conceptual recognition, and the consequent change of paradigm categories and procedures often accompanied by resistance.

There is even evidence that these same characteristics are built into the nature of the perceptual process itself. In a psychological experiment that deserves to be far better known outside the trade, Bruner and Postman asked experimental subjects to identify on short and controlled exposure a series of playing cards. Many of the cards were normal, but some were made anomalous, e.g., a red six of spades and a black four of hearts. Each experimental run was constituted by the display of a single card to a single subject in a series of gradually increased exposures. After each exposure the subject was asked what he had seen, and the run was terminated by two successive correct identifications.

Even on the shortest exposures many subjects identified most of the cards, and after a small increase all the subjects identified them all. For the normal cards these identifications were usually correct, but the anomalous cards were almost always identified, without apparent hesitation or puzzlement, as normal. The black four of hearts might, for example, be identified as the four of either spades or hearts. Without any awareness of trouble, it was immediately fitted to one of the conceptual categories prepared by prior experience. One would not even like to say that the subjects had seen something different from what they identified. With a further increase of exposure to the anomalous cards, subjects did begin to hesitate and to display awareness of anomaly. Exposed, for example, to the red six of spades, some would say: That’s the six of spades, but there’s something wrong with it— the black has a red border. Further increase of exposure resulted in still more hesitation and confusion until finally, and sometimes quite suddenly, most subjects would produce the correct identification without hesitation. Moreover, after doing this with two or three of the anomalous cards, they would have little further difficulty with the others. A few subjects, however, were never able to make the requisite adjustment of their categories. Even at forty times the average exposure required to recognize normal cards for what they were, more than 10 per cent of the anomalous cards were not correctly identified. And the subjects who then failed often experienced acute personal distress. One of them exclaimed: “I can’t make the suit out, whatever it is. It didn’t even look like a card that time. I don’t know what color it is now or whether it’s a spade or a heart. I’m not even sure now what a spade looks like. My God!” In the next section we shall occasionally see scientists behaving this way too.

Either as a metaphor or because it reflects the nature of the mind, that psychological experiment provides a wonderfully simple and cogent schema for the process of scientific discovery.

And from Revolutions As Changes Of World-View:

Surveying the rich experimental literature from which these examples are drawn makes one suspect that something like a paradigm is prerequisite to perception itself. What a man sees depends both upon what he looks at and also upon what his previous visual-conceptual experience has taught him to see. In the absence of such training there can only be, in William James’s phrase, “a bloomin’ buzzin’ confusion.” In recent years several of those concerned with the history of science have found the sorts of experiments described above immensely suggestive.

If you can read those paragraphs and honestly still think I’m just just irrationally reading predictive coding into a perfectly innocent book, I have nothing to say to you.

I think this is my best answer to the whole “is Kuhn denying an objective reality” issue. If Kuhn and the predictive coding people are grasping at the same thing from different angles, then both shed some light on each other. I think I understand the way that predictive coding balances the importance of pre-existing structures and categories with a preserved belief in objectivity. If Kuhn is trying to extend the predictive coding model of the brain processing information to the way the scientific community as a whole processes it, then maybe we can import the same balance and not worry about it as much.

Open Thread 118.5

Bay Meetup 1/6 Update

Due to rain, we’re switching to holding the meetup indoors at 3045 Shattuck Ave, Berkeley, 94705. There will be several floors of space available for overflow, so hopefully it won’t be too crowded. Thanks to Claire, REACH, and Event Horizon for setting this up.

Time is still 3:30 PM on Sunday, 1/6. There’s also a Facebook event here.

Preregistration Of Investigations For The 2019 SSC Survey

This post is about the 2019 SSC Survey. If you’ve read at least one blog post here before, please take the survey if you haven’t already. Please don’t read on until you’ve taken it, since this post could bias your results.

1. Can we confirm or disconfirm different corn-eating profiles of algebraists vs. analysts?

2. Can we replicate the study showing that people who eat more beef jerky are more likely to be hospitalized for bipolar mania?

3. Are there differences in side effects among SSRIs? (to be limited to people taking an SSRI one month or more, will be looked at both effect by effect, and with a lumped-together side effect index where each mild effect counts as 1 point and each severe effect as 3 points)

4. Is there a difference in people’s efficacy ratings for SSRIs (SSRI Effectiveness, SSRI Overall) depending on whether the person was taking the SSRI for depression vs. for anxiety?

5. What percent of people coming off SSRIs experience discontinuation symptoms? Are there differences among different agents? (main analysis to be limited to people who were taking an SSRI at least a few months, discontinued with a gradual taper lasting at least a few weeks, and were not cross-tapering onto any other psychiatric medication).

6. Are people more likely to attribute success to hard work/talent rather than luck if they are from a higher childhood social class? What about a higher current social class? What about if they have moved upward throughout their lifetime?

7. Are people less likely to support psychiatric commitment if they have been committed themselves? What about if they have a frequently-committed psychiatric issue (schizophrenia, bipolar, borderline, eating disorder)? Are they more likely to support commitment if they have a family member with those conditions, but don’t have it themselves?

8. Is there any support for the idea of life history strategies? (does early age of sexual debut and/or high number of sexual partners correlate with regular drug use, with leaving school earlier, and higher risk-taking? What about with being more likely to ask a partner out early or have nonconsensual sex? What about with various psychiatric disorders?)

9. Do paternal and maternal age correlate with risk of the psychiatric disorders? What about with the various self-ratings? What about with SAT score?

10. The question about labeling vegetarian foods (ie can a burger made of pea protein call itself a “burger”) seems to get at questions of essentialism vs. pragmatism in the same way as controversies about transgender. Do people who support essentialist labeling of food also support essentialist gender positions? What if we control for political identification? What if we exclude trans people and vegetarians (who probably care about this for personal reasons)?

11. Can we replicate the claim that people who had a younger sibling born during a supposed critical window for sexual imprinting (I think between 1 and 2 years old, but I will have to double check) are more exposed to baby-related issues during that window and so are more likely to have baby-related fetishes (lactation and diaper)?

12. Using the same definitions of STEM/nerdy/male vs. interpersonal/creative/female occupations as last time (see Figure 7 here), is there a difference between these groups in the rate at which people perceive gender bias?

13. How does imposter syndrome vary by gender, field, and gender * field?

14. Do schizophrenics (and their families) smoke more? Do autistics (and their families) smoke less?

15. Are schizophrenics (and their families) more likely to be able to tickle themselves than others? What about autistics (and their families)? What about people who have used lots of psychedelics?

16. Is tendency to prefer great literature to sci-fi/fantasy mediated by ability to perceive and appreciate complex emotion? (correlate difference in sci-fi enjoyment – literature enjoyment to autism, family autism. On a hunch, I am also going to correlate this with trustworthiness, which I think can be affected by a sort of paranoia which correlates with high-bandwidth-social-reading, and with ability to tickle self).

17. Do people with ADHD habituate to stimuli more or less quickly? This is a tough one, since there’s a common-sense argument for less (being more distractable suggests less able to drown out external stimula). But I have also heard people suggest they habituate more quickly, which is why they get bored so quickly, and why they so easily get distracted from what they’re doing. In retrospect, the question I asked (about habituation to a dripping faucet and other similar noises) is not ideal for this, but I’ll do what I can with it.

18. Do the birth order effects discovered in the last survey disappear if there’s a sufficient age gap between someone and their next youngest sibling, or remain equally strong? If I have enough sample size, I’ll limit this to families of exactly two people, then do an analysis like this one split for people with higher-than-median age gaps vs. people with lower-than-median age gaps. Birth order differences vanishing with high age gaps suggests they may be due to nurture (eg parents too busy parenting another kid to pay attention to you); remaining with high age gaps suggests potentially due to nature (eg maternal antigens or something).

What Happened To 90s Environmentalism?

0. Introduction

I grew up in the 90s, which meant watching movies about plucky children fighting Pollution Demons. Sometimes teachers would show them to us in class. None of us found that strange. We knew that when we grew up, this would be our fight: to take on the loggers and whalers and seal-clubbers who were destroying our planet and save the Earth for the next generation.

What happened to that? I don’t mean the Pollution Demons: they’re still around, I think one of them runs Trump’s EPA now. What happened to everything else? To those teachers, those movies, that whole worldview?

Save The Whales. Save The Rainforest. Save Endangered Species. Save The Earth. Stop Slash-And-Burn. Stop Acid Rain. Earth Day Every Day. Reduce, Reuse, Recycle. Twenty-five years ago, each of those would invoke a whole acrimonious debate; to some, a battle-cry; to others, a sign of a dangerous fanaticism that would destroy the economy. Today they sound about as relevant as “Fifty-four forty or fight” and “Remember the Maine”. Old slogans, emptied of their punch and fit only for bloodless historical study.

If you went back in time, turned off our Pollution Demon movie, and asked us to predict what would come of the environment twenty-five years, later, in 2018, I think we would imagine one of two scenarios. In the first, the world had become a renewable ecotopia where every child was taught to live in harmony with nature. In the second, we had failed in our struggle, the skies were grey, the rivers were brown, wild animals were a distant memory – but at least a few plucky children would still be telling us it wasn’t too late, that we could start the tough job of cleaning up after ourselves and changing paths to that other option.

The idea that things wouldn’t really change – that the environment would neither move noticeably forward or noticeably backwards – but that everyone would stop talking about environmentalism – that you could go years without hearing the words “endangered species” – that nobody would even know whether the rainforests were expanding or contracting – wouldn’t even be on the radar. It would sound like some kind of weird bizarro-world.

Just to prove I’m not imagining all this:

This is the volume of Google searches for “rainforests” over time. It goes up each year when school starts, and crashes again for summer vacation. But on average, there are only about 18% as many rainforest-related searches today as in 2004.

“Endangered species”, 25%

“Pollution”, 43%

And these are just since Google started tracking searches in 2004. The decline of 90s environmentalism must be even bigger.

So what happened?

Every so often you’ll hear someone mutter darkly “You never hear about the ozone hole these days, guess that was a big nothingburger.” This summons a horde of environmentalists competing to point out that you never hear about the ozone hole these days because environmentalists successfully fixed it. There was a big conference in 1989 where all the nations of the world met together and agreed to stop using ozone-destroying chlorofluorocarbons, and the ozone hole is recovering according to schedule. When people use the ozone hole as an argument against alarmism, environmentalism is a victim of its own success.

So what about these other issues that have since fizzled out? Did environmentalists solve them? Did they never exist in the first place? Or are they still as bad as ever, and we’ve just stopped caring?

1. Air And Water Pollution

Have you seen what Chinese cities look like on a smoggy day? Trick question: neither have the Chinese. The US used to be like that. I grew up near Los Angeles during the 1990s. My mother tells the story of a time when I was very young and my grandparents came to visit from the Midwest. “It reminds us of home,” they said, “it’s so flat.” “We’re surrounded by mountains”, my mother told them. We were. You couldn’t see any of them.

Environmentalists crusaded against this. Here are the results:

A lot of the credit goes to the Clean Air Act, passed in 1963 and tightened in 1990. Along with its more visible (pun intended) effects, scientists suspect it has prevented about 200,000 deaths from lung disease and a host of other cases of asthma, bronchitis, and even heart attacks.

It’s hard to find great data on water because there are so many different kinds of water and so many different ways it can be polluted. But just to choose a random very bad thing, here’s mercury levels in Great Lakes fish:

I don’t know of anyone claiming this is anything other than a response to stricter environmental laws.

As a result of these victories, people are no longer as concerned about air and water pollution. From Gallup:

This seems like a clear case of good work.

Verdict: Environmental movement successfully solved this problem.

2. Acid Rain

Acid rain is a combination of rain and pollution which gets very acidic and destroys plants and structures. It was a staple of very early 90s environmentalism, and understandably so: the prospect of acid falling from the sky and dissolving everything is very attention-grabbing. I remember the discourse focusing on statues; George Washington’s marble face slowly melting under sizzling raindrops makes a heck of an image.

I am not the first person to notice that Washington’s face remains mercifully unmelted. In 2009, Slate asked Whatever Happened To Acid Rain?. EPA Blog, 2010: Whatever Happened To Acid Rain?. 2012, Mental Floss: What Ever Happened To Acid Rain? By 2018 the Internet had advanced, so here’s the Whatever Happened To Acid Rain Podcast. Even the Encyclopedia Britannica, itself a good candidate for a “Whatever Happened To…” piece, has a What Happened To Acid Rain article.

Most of these sources say environmentalists solved acid rain by cutting down on emission of sulfur dioxide, the main offending chemical. A Bush I era cap-and-trade policy gets a lot of the credit in the US, but it looks like it was a broader effort than that:

There’s less clear data on rain acidity, but all my sources agree it has modestly declined in the US, thought it is still “between 2.5 and eight times more acidic than it should be”. Lakes and rivers are slowly recovering. On the other hand, in newly-industrializing countries like China and India, rain is becoming more acidic and they’re going through some of the same issues we were in the 80s.

This picture is slightly complicated by some people who claim acid rain was always exaggerated and “we solved it” is a convenient retreat from acknowledging this (for what it’s worth, these people tend to be global warming skeptics too). Most of them point to the 1990 National Acid Precipitation Assessment Program, a giant government investigation into the acid rain problem. I found a 1990 New York Times article on the report here:

A comprehensive Federal report that was supposed to resolve the issue of how much damage is caused to forests by acid rain has come under criticism from some distinguished scientists who are reviewing it.

The critics said that the report gave an incorrect impression that air pollution was not causing any large-scale problems for forest ecosystems. They also said that the report, still in draft form, ignored a number of studies suggesting serious air pollution problems.

But other experts contend that the general conclusion of the report is essentially right. The report concluded that with the exception of damage to red spruce at high elevations in the East, forests in the United States are not suffering serious damage from acid rain […]

The report now being reviewed is the final draft, completed at a cost of nearly $500 million. It examines the effects of other pollutants, like ozone, as well as acid deposits, and it concludes that air pollution causes far less environmental damage than has been feared.

An interim report issued by the study group in 1987, before Dr. Mahoney became director, was sharply criticized by many scientists. They contended that it tailored research findings into conclusions that matched the political goals of the Reagan Administration, which opposed new controls on air pollution. No such criticism has been leveled at the 28-volume final draft, which has been generally praised as a sound scientific document.

There is, however, some unhappiness among scientists with the volume dealing with forest health and productivity in the United States and Canada.

Dr. Ellis B. Cowling, associate for research at North Carolina State University’s College of Forest Resources, said in a telephone interview: ”The tone is that we don’t have a problem except in southern California, and with red spruce at high altitudes. That is not a fair statement of the state of scientific knowledge.” He added, ”Perhaps the authors were a bit too hasty in reaching conclusions.”

Dr. Cowling, who is highly regarded by colleagues as a conservative, solid scientist, wrote a memorandum to the authors of the forest health volume. He offered a series of suggestions for changing the wording of conclusions in ways that he said would reflect the state of science more accurately.

The first of those would change a finding that stated, ”The vast majority of forests in the United States and Canada are not affected by decline.” To be more consistent with the data, Dr. Cowling said, the conclusion should read: ”Most forests in the United States do not show unusual visible symptoms of stress, marked decreases in the rate of growth or significant increases in mortality.”

Just because symptoms of forest decline are not currently visible, Dr. Cowling argued, does not rule out the possibility that they are under way.

This article also provides a summary of contemporaneous responses to NAPAP, which quotes study director James Mahoney’s summary of his own report: “The sky is not falling, but there is a problem that needs addressing.”

I cannot find anyone really challenging the NAPAP report nowadays, so I provisionally accept that the damage from acid rain, while real, was exaggerated at the time.

There’s a related debate about how much the lakes and streams affected have recovered. Some lakes and streams are naturally acidic; there is some debate over what percent of lake/stream acidity is natural vs. acid-rain-related. In recent years this debate has focused on whether lakes/streams have recovered after the SO2 decline; if they haven’t, this might suggest their problems were never human-activity-related in the first place.

Global warming skeptic blog Watt’s Up With That claims they haven’t:

Possibly the greatest evidence against harmful effects of acid rain is the fact that acidic lakes have not “recovered” after most sulfur and nitrogen pollution was removed from the atmosphere. The 2011 NAPAP report to Congress stated that SO2 and NO2 emissions were down, that airborne concentrations were down, and that acid deposition from rainfall was down, but could not report that lake acidity was significantly reduced. The report states, “Scientists have observed delays in ecosystem recovery in the eastern United States despite decreases in emissions and deposition over the last 30 years.” In other words, the pollution was mostly eliminated, but the lakes are still acidic.

You can find the report here. Like all long government reports, the details are ten zillion different trends in different directions that don’t form a cohesive narrative, and the executive summary is “things are good in all the ways that suggest we deserve more money, but bad in all the ways that suggest we need more money”, It is complicated enough that you shouldn’t trust my excerpting, but at least to me the relevant excerpts seem to be:

Levels of acid neutralizing capacity (ANC), an indicator of the ability of a waterbody to neutralize acid deposition, have shown improvement from 1990 to 2008 at many lake and stream long-term monitoring sites in the eastern United States, including New England and the Adirondack Mountains. Many lakes and streams still have acidic conditions harmful to their biota even though the increases in ANC indicate that some recovery from acidification is occurring in sensitive aquatic ecosystems

And:

Despite the environmental improvements reported here, research over the past few years indicates that recovery from the effects of acidification is not likely for many sensitive areas without additional decreases in acid deposition. Many published articles, as well as the modeling presented in this report, show that the SO2 and NOx emission reductions achieved under Title IV from power plants are not recognized as insufficient to achieve full recovery or to prevent further acidification in some regions.

So Watts seems to be mostly wrong when they say lakes are not recovering, but mostly right when they say ecosystems are not recovering. But NAPAP has some explanations for why ecosystems are not recovering: first, if you poison a lake and kill everything, then even if you remove the poison later everything is still dead. Second, there are complicated natural cycles that gradually wash old deposited land-based pollution into lakes, and it will be a long time before all the pollution deposited on land gets fully washed away. Third, maybe we haven’t fought acid rain hard enough.

I think a lot of the epistemic work here is going to get done by people’s respective stereotypes about the trustworthiness of global warming denialists vs. big government agencies whose budget depends on there being a problem. But my impression is that Watts’ claim that poor recovery suggests acid rain was never a problem don’t hold up very well.

In any case, it’s undeniable that rain has become a lot less acid lately, and likely that this has at least modest positive effects on some ecosystems as well as on the built environment. Anti-Confederate protesters have replaced acid rain as the number one threat to our statues. Our precious, precious statues. Someday they will be safe.

Verdict: A little of everything: partly solved, partly alarmism, partly still going on.

3. The Rainforests

Maybe the most typical image of 90s environmentalism is men in bulldozers clear-cutting a rainforest, while tapirs and tree sloths gently weep.

Or maybe it was the declining-rainforest-coverage-over-time-maps. I feel like about one in every three posters I saw as a child looked something like this:

This is a fake example. Please stop asking me where I am getting the data from.

I thought surely nothing could be easier than digging up a few of them and seeing whether their 2020 predictions were right. But I can’t find them anywhere. According to the Internet, there is no such thing as 90s-era maps showing declining rainforest coverage over time. Can anyone else locate these?

Anyway:

Here’s a graph of the size of the Amazon over time (source, note that the y-axis is not at zero). At 90s levels of deforestation, the Amazon would have disappeared in about 200 years. At current levels, it will disappear in about 400 years.

Here’s the Congo (somewhat dubious source, same caveat). At the rates shown here it will be gone in 250 years – but it seems to have slowed after the period on the graph.

And here’s Southeast Asia (source, same caveat). At this rate, the southeast Asian forest will be gone in 150 years, though some new papers are suggesting we may be underestimating the deforestation rate.

Overall it looks like deforestation may have decreased modestly in the Amazon (and possibly the Congo) since the 1990s. It has not decreased significantly in Southeast Asia, and whatever decreases have happened are not relevant to the scale of the problem.

The only good news is that all those “rainforests will be gone by 2050” posters were just wrong; there is more rainforest than that. But not that much more.

Verdict: The problem still exists, and we are just ignoring it now.

4. Endangered Species

So just find how many species go extinct each year, and whether it’s a lot or a little, and then we’ll know what’s going on with this, right? Ha ha, as if.

On the one hand, the UN Environment Programme says that “150-200 species of plant, insect, bird and mammal become extinct every 24 hours.”

On the other, nobody can name more than a single-digit number of species that go extinct in any given year. The 2017 list includes five: a bat, a cat, a flatworm, a lizard, and a snail. This matches longer-term surveys: Ceballos et al (2018) find that about 477 vertebrate species have gone extinct since 1900 – again, about five per year. And a recent survey found only four to eight bird species had disappeared since the turn of the century.

I have no idea where the 150-200 number per day comes from, and neither does anyone else. The closest I can find to a justification is this WWF page, which reminds us that if there are 100 million animals species, and “the extinction rate is just 0.01% per year”, then at least 10,000 species go extinct every year (=200-300/day) – but all of these numbers are completely made up.

One could try to justify these estimates with something like “assume only one in a thousand species has been discovered and is monitored well enough to detect its extinction, so if we detect five extinctions per year then five thousand must be happening” – but I’ve never heard anyone actually say this. Also, with apologies to all the undiscovered species, if they’re so tiny and uncommon as to never get discovered, it doesn’t seem like their extinction is going to change very much.

Five known species going extinct per year may sound like a lot if you’re thinking it’s something like “rhinos, pandas, whales, spotted owls, and leopards”. But realistically there are 385 species of shrews. We could spend our entire yearly extinction budget on shrews for the next sixty years and still have more than enough kinds of shrews left to satisfy basically anybody.

I’m trying to think what the best counterargument to this would be – the best case that we really do need to consider species extinction a dire concern.

Maybe this is too vertebrate-centric, and there are lots of insects and plants and such going extinct all the time? But this List Of Recently Extinct Insects suggests that of about 6000 known insect species, only 50-100 have gone extinct in the past century. And one of those was this giant earwig which I really think the world is better without.

Or maybe we can’t directly predict the future from the past. Imagine 1000 square miles of rainforest with a homogenous distribution of species. Clear-cut 50% of the rainforest, and no extinctions. Clear-cut 90% of the rainforest, still no extinctions. Clear-cut 99%, maybe a few extinctions if you’re unlucky. Then clear-cut the last remaining 1% and everything dies. It seems like something like that might be happening – see for example this report that global animal populations have declined 58% over the past forty years.

But any concept of endangered species that focuses on “many well-known species will be gone soon” doesn’t seem consistent with the evidence.

Verdict: Partly alarmism, partly still going on.

5. More And More Trash Piling Up Until The Whole World Is Just A Giant Mountain Of Trash

Wait, what? Was this really a concern? Did I really spend my primary school years being told that if I didn’t vigilantly recycle everything, one day I would be submerged beneath a sea of trash, breathing by means of a trash snorkel? Am I hallucinating all of this?

As usual, it turns out to be the Mafia’s fault. In the 1980s, mob boss Salvatore Avellino took over New York City’s landfill industry, and in a shocking development which nobody could have predicted, was corrupt. New York City soon ran out of landfill space. Somehow all of its excess trash ended up on a barge called the MOBRO-4000, because the Eighties, and this barge apparently sailed up and down the east coast of North America searching for a place to deposit its trash. In its many exciting adventures it reached the coast of Belize, got involved in a confrontation with the Mexican Navy, and finally went back to New York, where at some point landfill space was found and the crisis was over.

But a giant boat full of trash made a really memorable image, and it got nationwide news coverage, and environmentalists took advantage of this to tell everyone there was no more landfill space anywhere in the world and we all had to recycle right now. According to Wikipedia:

At the time, the Mobro 4000 incident was widely cited by environmentalists and the media as emblematic of the solid-waste disposal crisis in the United States due to a shortage of landfill space: almost 3,000 municipal landfills had closed between 1982 and 1987. It triggered much national public discussion about waste disposal, and may have been a factor in increased recycling rates in the late 1980s and after. It was this that caused it to be included in an episode of Penn & Teller: Bullshit! (season 2, episode 5) in which they debunk many recycling myths.

I’m even absolutely right in remembering primary school lessons centered around garbage covering the Earth and killing everybody. Here’s a New York Times article from 1996 – ie after the crisis had a little bit of time to fade – lightly mocking the new curricula that followed in its wake:

After the litter hunt in Ms. Aponte’s science classroom, it was time for a guest lecturer on garbage. A fifth-grade class was brought in to hear Joanne Dittersdorf, the director of environmental education for the Environmental Action Coalition, a nonprofit group based in New York. Her slide show began with a 19th-century photograph of a street in New York strewn with garbage.

“Why can’t we keep throwing out garbage that way?” Dittersdorf asked.

“It’ll keep piling up and we won’t have any place to put it.”

“The earth would be called the Trash Can.”

“The garbage will soon, like, take over the whole world and, like, kill everybody.”

Dittersdorf asked the children to examine their lives. “Does anyone here ever have takeout food?” A few students confessed, and Dittersdorf gently scolded them. “A lot of garbage there.”

She showed a slide illustrating New Yorkers’ total annual production of garbage: a pile big enough to fill 15 city blocks to a height of 20 stories. ‘There are a lot of landfills in New York City,” Dittersdorf said, “but we’ve run out of space.”

From the same beginning-of-the-backlash period we also get this 1995 Foundation for Economic Education piece, Are We Burying Ourselves In Garbage?:

A popular idea in public discourse today is that the United States produces an overwhelming amount of trash–so much that our landfills will not be able to handle the quantity. The most eloquent symbol of this viewpoint was the “garbage barge,” which in the late 1980s left Long Island and could not find a port or country willing to accept its 3.168 tons of refuse. [But] the actual data (such as they are) on the amount of municipal solid waste produced present us with more questions than answers.

This article also deserves note for hitting on a brilliant solution:

The crisis mentality has distorted judgment of waste disposal. The notion that modern America is especially wasteful is demonstrably wrong, both in terms of the last decades as well as the last 100 years. The idea that our landfills are literally “running out” is even less credible. If in the next century major portions of the United States really need to export their refuse to other states, a “gold mine” for refuse burial does exist: South Dakota. This state is geologically, economically, and politically almost ideal for massive municipal solid waste management.

None of this is a joke. This is how your parents did Discourse, people.

But it turns out capitalism works: if there’s a shortage of landfills, that incentivizes people to create new landfills. Also, the world is very large and it is hard to cover a significant portion of it in trash. There was a brief blip as cities figured out how to pay for more waste disposal, and then nobody ever worried about the problem again. Recycling remained inefficient and of dubious benefit, and never really caught on.

There is still an international problem as Third World countries struggle with infrastructure issues around trash disposal. You still see occasional articles like Huffington Post’s People Are Living In Landfills As The World Drowns In Its Own Trash, from earlier this year. But I think in general nobody in the First World still considers this a major problem.

Well, almost nobody:

Verdict: Alarmist. So, so, alarmist.

6. Peak Resource

Is the earth’s ballooning human population using up resources at an unsustainable rate?

Technically the answer must be “yes”, since by definition nonrenewable resources have to run out at some point. But when? Long after we have escaped to space and gotten access to shiny new resources? Or soon enough that we have to worry about it?

A big part of 90s environmentalism involved worrying that it was the latter. A particular concern was “peak oil”, the point at which we had exhausted so much of the world’s oil that production rates declined every year thereafter and oil started becoming gradually rarer and more expensive. Wikipedia has a helpful table of people’s peak oil predictions. I’ve highlighted the ones that have already passed in red.

Almost everyone working before 2000 thought we would have reached peak oil by now. But here’s world oil production over time:

And the price of oil:

What happened? People discovered fracking and other paradigm-shifting techniques to extract oil from shale, which opened up vast new previously-inaccessible oil fields. The peak oil predictors might call this unfair – they calculated correctly given the technology they knew about – but the whole argument of the people who say we don’t have to worry about peak resource (sometimes called “cornucopians”) is that technology will advance fast enough to satisfy our resource needs. In this case they were right.

What about non-oil resources?

In 1980, leading environmental scientist and peak-resource proponent Paul Ehrlich made a bet with cornucopian economist Julian Simon about how resource prices would change over the next decade. The Simon-Ehrlich Wager has become a famous example of futurology done right – two people with different theories implying different predictions coming together, agreeing on exactly what each of their theories implied, and then publicly committing to put them to the test. According to Reb Wiki:

Simon challenged Ehrlich to choose any raw material he wanted and a date more than a year away, and he would wager on the inflation-adjusted prices decreasing as opposed to increasing. Ehrlich chose copper, chromium, nickel, tin, and tungsten. The bet was formalized on September 29, 1980, with September 29, 1990 as the payoff date. Ehrlich lost the bet, as all five commodities that were bet on declined in price from 1980 through 1990, the wager period.

Looks pretty good for Simon and the cornucopians. But the article continues:

Ehrlich could have won if the bet had been for a different ten-year period. Ehrlich wrote that the five metals in question had increased in price between the years 1950 to 1975. Asset manager Jeremy Grantham wrote that if the Simon–Ehrlich wager had been for a longer period (from 1980 to 2011), then Simon would have lost on four of the five metals. He also noted that if the wager had been expanded to “all of the most important commodities,” instead of just five metals, over that longer period of 1980 to 2011, then Simon would have lost “by a lot.” Economist Mark J. Perry noted that for an even longer period of time, from 1934 to 2013, the inflation-adjusted price of the Dow Jones-AIG Commodity Index showed “an overall significant downward trend” and concluded that Simon was “more right than lucky”. Economist Tim Worstall wrote that “The end result of all of this is that yes, it is true that Ehrlich could have, would have, won the bet depending upon the starting date. … But the long term trend for metals at least is downwards.”

How about today? An econblogger is still keeping track of the Ehrlich-Simon wager, and finds that as of August 2017, Simon (who is now dead) is still winning; a basket of the five metals involved still costs less than it did in 1980.

Can we zoom out even further? There are a bunch of commodity indices that do for commodities what the Dow Jones does for stocks. I chose the Standard & Poor Goldman-Sachs Commodity Index kind of randomly because they were a familiar name and it was easy to find which goods they included. I’m not quite sure I’m doing this right, but this seems to be the most relevant graph:

The price of commodities in general is still lower than in 1980 (also, with this graph it becomes clear Ehrlich was really unlucky in which year he started his wager).

I have never heard anyone claim that this represents an environmentalist victory: I don’t think there was any large-scale attempt to conserve or recycle chromium/tungsten/whatever that led to its current abundance. I think this was just a victory for resource extraction technology.

There are still theoretical reasons to think we have to run out of stuff eventually. But in terms of how the past 25 years have treated 90s-era concerns about resource depletion, it’s hard to answer anything other than “savagely”.

Verdict: Alarmist

7. Saving The Whales

I remember frequently being told we had to do this. Apparently it paid off, since a global moratorium on whaling was signed in 1982.

The ban is not perfect. Indigenous peoples are allowed to hunt whales in traditional ways. Japan pretends their whaling is for “scientific purposes” and has so far gotten away with it. Norway and Iceland never signed the moratorium and continue to whale.

But overall, things are going pretty well. There aren’t a lot of graphs, but the International Whaling Commission (which despite its name is against whaling) says blue whale populations are increasing at about 8%/year, humpback whales around 10%, and fin whales around 5%. Those sound pretty good, but they have to be taken in context:

Okay, fine. There’s one graph. But it’s really depressing. See that tiny micro-bump at the end? That represents progress.

Verdict: Environmental movement successfully solved this problem.

8. Concluding Thoughts

This was not a very conclusive exercise. When I add these up – as if that were at all an acceptable thing to do! – I get 2⅓ that were solved, 2⅚ that were alarmism, and 1⅚ that continue. So there is not much to be said about them as a group. Some were solved through heroic effort. Some turned out to be completely made up. Some of them are still out there but have stopped capturing the public’s attention.

Victories I can understand. It’s the latter two categories that confuse me.

How did the non-problems fade away? There was no moment when some brave iconoclast posted ninety-five theses to the door of the local recycling center and said “No! There is not a landfill crisis!” I mean, John Tierney wrote things along those lines, and did a great job of it. But he’s not a household name and there was never a time when everyone said “Oh, John Tierney is right, let’s stop worrying about this.” The people who stopped worrying about this never heard of John Tierney. At some point people just went from being very worried about the landfill crisis to shaking their heads and saying “The world getting full of trash? Sounds pretty stupid.”

And the story with peak resources seems entirely different. You will still occasionally see people saying “The Earth can’t support our greed, soon we will run out of everything”, and reasonable people will nod along with this and admit it is very wise. But you hear it like once a year now, as opposed to it being a constant refrain. This idea was never intellectually defeated at all, at least not on the popular level. It just faded away.

Was there some rarified level of intellectual debate where these ideas lost out? And then, denied their support from the commanding heights of the ivory tower, did journalists stop writing about them, schoolteachers stop teaching them, and then eventually the public – who have no will of their own and have to be told what matters – wander off and do something else?

Or was the change bottom-up? Did the public, after the millionth editorial on the trash crisis, say “Okay, whatever”, such that journalists realized this was no longer a good way to sell newspaper subscriptions? Is there a natural news mega-cycle of a decade or so, after which the public gets tired of hearing about a certain story, the intellectuals get tired of talking about it, every possible angle has been explored, and people move on, whether or not it was solved? Does this explain why the rainforests, a real problem that is still going on, similarly lost public attention?

Or maybe climate change took over everything, became so important that everything else faded into the background. This is certainly how it feels to me. Whenever I hear about the rainforests nowadays, it’s as a footnote to some global warming story where they add that we should save the rainforest as a carbon sink. Whenever I hear about landfills or recycling today, it’s in the context of trash giving off greenhouse gases. It feels almost like some primitive barter system has been converted to a modern economy, with tons of CO2 emission as the universal interchangeable currency that can be used to put a number value on all environmental issues. Can’t figure out a way to convert whales into a carbon sink? Guess they’ll have to go.

(I wrote that, then remembered I lived in 21st century America, did a Google search, and sure enough there are dozens of articles arguing that saving whales is an efficient way to neutralize greenhouse gases)

But as attractive as this picture is, it’s hard to find the supporting data. There’s just not hard evidence that we care more about global warming than we did fifteen or twenty years ago:

Here’s the Google Trends. There was a lot of interest in 2006, which I think gets attributed to Al Gore’s An Inconvenient Truth in that year, but not a lot of signs of increase today.

Here’s Gallup. It at least shows a spike starting in 2016 – but given its timing and the lack of obvious 2016 global-warming related events, I think it’s probably just another Trump backlash effect.

If global warming is eating all the other environmental issues, it doesn’t seem to be extracting that much nutrition from their corpses. And the ozone hole – probably the most global-warming-like issue of the last generation – managed to gather popular support at the same time that people were worried about a host of other things. I don’t know. Maybe given the public’s tendency to get bored of an issue after a decade or so, global warming has to cannibalize the rest of environmentalism just to survive at all. Depressing if true.

Or maybe it’s a zeitgeist thing. For some reason, it’s hard to imagine 2018 being the Year Of Rainforest Concern. There’s something very 90s Optimism about worrying about the rainforests, something where even the warnings of doom have a cheerful ring to them. I remember a Rainforest Charity Box at my local mall as a kid, promising that if you donated $10, you would save a brightly colored parrot, and if you donated $50, you might save a jaguar. Who thinks that way these days? Now if you donate some amount to stopping global warming, you will have won yourself a lecture from a bunch of people telling you that still doesn’t mean you have the right to feel good about yourself, and the world is going to fry regardless. Have we just passed the point where anybody can care about crisp mountain streams or frolicking snow leopards any more?

The most important thing I take away from the exercise is a sort of postmodern insight into the way environmental issues are constructed. This is definitely not me saying they are all made up; many of them are very real. But the mapping from real crisis to social panic is tenuous, contingent, and historical. Sometimes random things that shouldn’t matter get magnified into the issue du jour; other times giant world-threatening crises manage to slip everyone’s attention.

Imagine that twenty years from now, nobody cares or talks about global warming. It hasn’t been debunked. It’s still happening. People just stopped considering it interesting. Every so often some webzine or VR-holozine or whatever will publish a “Whatever Happened To Global Warming” story, and you’ll hear that global temperatures are up X degrees centigrade since 2000 and that explains Y percent of recent devastating hurricanes. Then everyone will go back to worrying about Robo-Trump or Mecha-Putin or whatever.

If this sounds absurd, I think it’s no weirder than what’s happened to 90s environmentalism and the issues it cared about.

OT118: Threadgorian Calendar

This is the bi-weekly visible open thread (there are also hidden open threads twice a week you can reach through the Open Thread tab on the top of the page). Post about anything you want, but please try to avoid hot-button political and social topics. You can also talk at the SSC subreddit or the SSC Discord server – and also check out the SSC Podcast. Also:

1. Comment of the week is by Liskantope, who is not buying the story (the conspiracy theory?) that supercentenarian Jeanne Calment was a fraud.

2. Did you go to a secular Solstice celebration this year? Did you like the music? Raymond Arnold, the composer of most of the Solstice songs, has a crowdfunding campaign to get an album out. It’s finishing tomorrow, so if you’re interested make sure to take a look ASAP (sorry!) Campaign is over, you can still support/purchase at this link.

3. Somebody determined that the Report Comment button works on https but not http. If you have trouble using the button, try using it on https. And if you understand these things and have a good idea how to make it work on http, let me know.

4. If you’re hosting an SSC meetup and want it to show up in the Upcoming Meetups section of the sidebar here, remember to fill in this form (it’s linked on the sidebar) and to tag the meetup with “SSC”.

5. Some new ads up. One is for GiveDirectly, a charity which directly transfers money to needy people in Africa. The other is for Charity Entrepreneurship, a Y-combinator-esque incubator for people who want to start non-profits. Remember, I do give free advertising to EA charities and organizations – though you might want to wait a little while, right now I’ve got a higher free-to-paid ad ratio than I’m used to.

6. The survey is still open, so if you haven’t done it yet and you’re reading this post, please take the 2019 Slate Star Codex survey. If you’ve already taken it and you want more surveys, user RavenclawPrefect has put together a supplemental survey of all the questions that didn’t make it in to the main one.

7. Happy New Year, everyone!

Please Take The 2019 SSC Survey

Please take the 2019 Slate Star Codex Survey.

The survey helps me learn more about SSC readers and plan community events. But it also provides me with useful informal research data for questions I’m interested it, which I then turn into interesting posts. My favorite from last year was Fight Me, Psychologists: Birth Order Effects Exist And Are Very Strong, which I think made a real contribution to individual differences psychology and which could not have happened without your cooperation.

The survey is open to anyone who has ever read a post on this blog before December 27 2018. Please don’t avoid taking the survey just because you feel like you’re not enough of a “regular”. It will ask you how much of a “regular” you are, so there’s no risk you’ll “dilute” the results. The survey will stay open until mid-January, and I will probably be begging and harassing you to take it about once a week or so until then.

This year’s survey is in two parts. Part I asks the same basic questions as previous years and should take about ten minutes. Part II asks more questions on research topics I’m interested in and should take about fifteen minutes. It would be great if you could take both parts, but if 25 minutes sounds like too much surveying to you, you can also just take Part I.

As always, the survey is plagued by fundamental limitations, poor technology, and my own carelessness, but a couple of things to watch for:

– Once you click a box on a Google form, you cannot un-click it – i.e. you can change your answer but you can’t unanswer the question. If you click a box you didn’t mean to, please switch your answer to “Other” if available; if not, then choose the most boring inoffensive answer that is least likely to produce surprising results. I realize how bad this is but there is apparently no way around it.

– Some of the questions are America-centric, because I either have to learn everything about every culture or be something-centric, and America seemed like a good place to center around. Sorry to non-American readers. Feel free to skip any questions that don’t apply to you.

– By default, all responses will be included in a public dataset for anyone who wants to analyze them. Your responses will obviously not be attached to your name or any similarly blatant identifying information, but if you are the only 92 year old from Uruguay on SSC then someone could theoretically identify you. There is an option to make all your responses private; if identifiability bothers you, feel free to check it and you will not be included in the public dataset. There are a few sections of Part II, especially the ones on drugs and sex, which I figure need extra privacy protection; I will not be sharing these regardless of your answer to the privacy question.

– Due to poring over a 5000 entry spreadsheet not actually being that much fun, I am not up for changing your answers after you submit them. Please do not email me asking me to do this. This includes your answer to the privacy question. Please figure out whether you want privacy before taking the survey.

That having been said, you are all great, and I super-appreciate any survey-filling-out you are willing to do. If you can donate about a half-hour, I hope I can pay you back in interesting findings and useful crowd-sourced life advice. So:

Links 12/18: Boughs Of Hollink

A Swedish news team went to Gotland to film a segment on the problem of amateur treasure-hunters disturbing archaeological sites. To collect footage, one of them borrowed a metal detector and went around an archaeological site in what they figured was a treasure-hunter-like way. Just after filming finished, the metal detector started beeping – and thus was made the largest discovery of Viking treasure in history, 148 lbs of silver worth millions of dollars.

Remittance men were the embarrassing or redundant children of wealthy European families, promised a regular income on the condition that they stay away from home. They ended up in American, Canada, and the British Empire, and were common enough to make up an outright majority of some Old Western towns.

Nintil takes a stab at explaining the constancy of the rate of GDP growth. Short version: GDP depends on population (which grows smoothly), capital (which accumulates smoothly), and productivity (which grows in fits and starts that are somewhere between random and autocorrelated but when averaged across all technologies approximates smooth). Also, processes driven by exponential growth are naturally smooth-looking.

Early 18th-century London looked a lot like the setting of the average superhero comic – plagued by crime, weak on policing, crying out for a charismatic figure to take matters into his own hands. Enter Jonathan Wild, the “Thief-Taker General”, who won public adoration by catching all the worst criminals and bringing them to justice. Spoiler: he was secretly a mob boss who arranged all the crimes, then arranged to “solve” whichever ones benefitted his reputation.

Great moments in censorship: In 1953, the USSR non-personned former spymaster Lavrentiy Beria.

The Energy Desert is an area from about 10^12 to 10^25 electron-volts – eg between 20th century particle accelerators, and ones billions of times better than that – where many theories predict that nothing interesting happens.

The big genetics news this month was the claim that two babies born in China were CRISPRed to make them immune to AIDS. Leading US biologist George Church has seen the data and seems to think it’s for real. Most scientists condemned the action (though it’s hard to tell how organic that was, since several started out cautiously supportive, then switched to condemning it after they themselves were condemned for not condemning it enough). On the other hand an earlier survey shows that 60% of Americans, 70% of Chinese, and almost 100% of Chinese with AIDS believe that gene editing to prevent AIDS and other serious diseases is potentially (though not necessarily in this case) acceptable. Have not heard of any attempt to see how many other genes were damaged in editing attempt, but this seems like potential next step. After claim that the scientist involved went missing, he has since become un-missing and promised to say something in his own defense at some point. There’s some good debate about the ethics of this here.

How did restaurants get so loud? I SAID, HOW DID RESTAURANTS GET SO LOUD? Seems to be combination of minimalist design removing sound-absorbing stuff, plus sinister motive in preventing long conversations to get people out earlier and so increase throughput and profits.

Suicide is declining basically everywhere except the United States. Or at least this is how the article presents it – it doesn’t look at a lot of other western First World countries, and it seems to hint at a “there is a developmental stage where suicide rate plummets, the US had it fifty years ago, and China, India, etc are having it now”. Also, although looks at rising US death rates usually mention whites as uniquely affected, the second graph here suggests that whites and Native Americans follow one (worsening) pattern, and blacks/Asians/Hispanics another (improving) one. What do whites and Native Americans have in common? Ruralness?

Mic.com is dead. This may seem like a small thing, but now all the terrible social justice clickbait websites have to journey all the way back to Mongolia to elect a new Khan. We’re saved! Everyone is saved! Related: BoingBoing discusses the sinister side of Facebook’s pivot to video.

Noah Smith and Random Critical Analysis debate health care – specifically, Noah subscribes to the popular belief that US health care is uniquely expensive because it is uniquely inefficient, vs. RCA’s believes that richer countries have more expensive health care, and once you measure this more accurately the US is exactly where you would expect on the trend line. Noah starts with a Bloomberg article that offhandedly calls RCA “unconvincing”. RCA responds with a gargantuo-mega-post containing almost 300 graphs proving himself right, to which Noah tweets a 23 word response. See also the discussion on the SSC subreddit.

This month in free speech: Marc Lamont Hill was fired as a CNN commentator – and almost lost his tenured professorship at Temple University – for giving a pro-Palestine speech at the United Nations. Opponents claimed that his call for a Palestinian state “from the [Jordan] River to the [Mediterranean] Sea” was a “dog-whistle” calling for the extermination of Jews. I think it’s important that everyone remember free speech for everyone stands or falls together – so I’m happy that some rightist defenders of free speech have expressed concern about this, and also disappointed that some leftists tried to exploit the severity of this case to trivialize right-wing free speech concerns.

Seen on Reddit: “TIL there was an early 1900s act named ‘Sober Sue’, whose draw was she never smiled. A theater offered $1000 to any one who could make her laugh, attracting big comedians.

As far as I know not actually done as a gimmick by anti-transgender activists but sounds like the sort of thing they would think up: 69 year old Dutch man says he identifies as a 49-year-old, asks court to change his legal age.

Strong evidence that increased school spending can improve school outcomes. My argument against this has always been secular doubling or tripling of spending that hasn’t done much, but I guess there could be two causes of school spending – secular cost increases, and actually useful stuff, and the second one is actually useful.

In 2012, English royal Kate Middleton was in the hospital recovering from severe morning sickness. Some Australian radio comedians called the hospital doing an outrageous Queen Elizabeth impression, and the hospital fell for it and talked to them as if they were the real Queen. Then one of the nurses involved committed suicide, leading to a closer look at the ethics of radio comedy.

Although NYC leads the country in anti-Semitic hate crimes, none in the past two years has been affiliated with any kind of far-right group; they are mostly perpetrated by anti-gentrification activists who see Jews as “hyper-white”. No data about how nationally representative this is compared to far-right anti-Semitic crimes like the recent Pittsburgh shooting. Suppose it were representative: given that we frequently hear calls to crack down on far-right ideas out of fear of inflaming anti-Semitism, and that we never hear calls to crack down on anti-gentrification speech or the discourse around whiteness out of fears of inflaming anti-Semitism (and most people would be horrified by the idea that we should), should this challenge the way we think about hate-crime-incitement as an exception to free speech?

Scott Weiner’s SB-827, the California bill that would have upzoned huge swathes of the state and marked a major victory against the housing crisis, failed to make it out of committee last year.

How Different Studies Measure Income Inequality is a good article on how most ways of measuring inequality find less dramatic results than the famous studies by Piketty et al. It also argues that real median incomes have increased about 40% since the 1970s (contra the common argument that they have been basically flat as all growth goes to the top 1%).

For a long time, Bangladesh – whose garment industry has become almost synonymous with sweatshops – has been used as a critique of capitalism. And for an equally long time, capitalists have said this is a process countries have to go through and in a few years Bangladesh will reap a reward of economic growth and development. So it’s relevant to hear that Bangladesh is booming, with per capita income tripling in a decade, poverty rates cut in half, near food self-sufficiency, and the UN graduating them out of “least developed country” status.

Dylan Matthews’ Vox article about why it’s not worth trying to get along with political enemies, and kbog’s critique of same. Linking this not because I think the article is good and want you to read it, or because I think the article is especially bad and have forgotten that hate-linking incentivizes bad behavior. I’m linking it because it makes basically the argument I warn is driving people’s behavior in the last part of Against Murderism, and people kept objecting that I was straw-manning and nobody really thought that. I argue against these things because it’s what lots of people actually believe, and although sometimes it’s said quietly and scattered across a lot of places, if you wait long enough someone will just turn the whole thing into a Voxsplainer.

Here, have a neat animated gif about how the same facts are compatible with multiple different interpretations (but see also this thread).

Jeanne Calment, who died in 1997 at the age of 122, is widely believed to be the oldest person ever. Scientists were puzzled by her health and long life, which was an extreme outlier even among record-holding supercentanarians. Now a Russian gerontologist presents evidence that Calment was a fraud – she died at a normal age, and her daughter assumed her identity for financial reasons. This was great to see a few days after reading Gwern’s list of open questions, where he expresses bafflement on how Calment lived so much longer than theory would predict possible.
