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 times, both in the SSC sample and in other samples of high-opennness STEM types. Last year, I expanded those results to look at how age gaps affected birth order effects. Curiously, age gaps less than seven years did not seem to attenuate birth order, but age gaps of more than seven years attenuated it almost completely.

Bucky analyzed the same data and found that I bungled one and a half of my results. Left graph in each pair is mine, right is Bucky’s.
