Congratulation to one of our newest grad students My Linh Huynh-Lucero (@mylinhhulu.bsky.social) who has secured a highly competitive NSF GRFP award, recognizing outstanding graduate students in STEM. This year there was only a 5% acceptance rate in the life sciences, so very well done My Linh.

The โ€œIโ€ in egalitarianism: Hadza hunter-gatherers averse to inequality primarily when personally unfavorable Abstract. Many economists contend that humans have strong, universal, other-regarding equality preferences with deep evolutionary roots. Indeed, many hunte

๐Ÿ“ข New Paper ๐Ÿšจ

Excited to get this paper published! ๐ŸŒŸ

We argue that men exaggerate patriarchal beliefs in an effort to signal conformity to others, which in turn fuels misperceptions about peers - making patriarchal norms resistant to change.

"Models casting egalitarian societies as crucibles of equality perpetuate the factually uninformed notion that foragers are somehow more noble. Critiques portray egalitarianism as romantic fantasy. Neither characterization is wholly justified."

If one man marries two women, another man must go unmarried, right? No. Demography matters. If sex ratios are skewed towards women, then polygyny can exist alongside universal marriage for men (who want to marry women). If only more people understood demography ๐Ÿ˜Š

New paper led by @anushe.bsky.social on alloparenting in Tanzania. Child care assistance surely benefits child health, but we find little evidence that specific care arrangements are more resilient than others.
