[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
