Sleep Support: An Individual Randomized Controlled Trial

I worry my sleep quality isn’t great. On weekends, no matter when I go to bed, I sleep until 11 or 12. When I wake up, I feel like I’ve overslept. But if I try to make myself get up … Continue reading

[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
