[Partial Retraction] Age Gaps and Birth Order Effects

On Less Wrong, Bucky tries to replicate my results on birth order and age gaps. Backing up: two years ago, I looked at SSC survey data and found that firstborn children were very overrepresented. That result was replicated a few … Continue reading

Attempted Replication: Does Beef Jerky Cause Manic Episodes?

Last year, a study came out showing that beef jerky and other cured meats, could trigger mania in bipolar disorder (paper, popular article). It was a pretty big deal, getting coverage in the national press and affecting the advice psychiatrists … Continue reading

[PARTIALLY RETRACTED] Cortical Neuron Number Matches Intuitive Perceptions Of Moral Value Across Animals

[EDIT: No longer confident in this post, see here.] Yesterday’s post reviewed research showing that animals’ intelligence seemed correlated with their number of cortical neurons. If this is true, we could use it to create an absolute scale that puts … Continue reading

Kernel Of Doubt: Testing Math Preference Vs. Corn-Eating Style

In 2010, Ben Tilly of the blog Random Observations wrote Analysis Vs. Algebra Predicts Eating Corn?, which said: I like learning about odd connections between disparate things. This probably is the oddest example that I know. Broadly speaking, mathematicians can … Continue reading

[Epistemic status: low. You tell me if you think this works.] Commenter no_bear_so_low has been doing some great work with Google Trends recently – see for example his Internet searches increasingly favour the left over the right wing of politics … Continue reading
