This is a mammoth piece of measurement work for evolutionary psychiatry, that hopefully triggers more rigorous testing of evolutionary theories of mental health.
Camila et al. have spent several years(!!!) developing this vital piece of work, so do check it out and share

I felt like I was losing my mind watching this person's remarks and had to write about how disgusting they are.
Sarah Hurwitz Profanes the Holocaust

Which processes underlie collective intelligence in naturalistic human groups?
In new work led by Valerii Chirkov, we show that payoff selectivity is key in transforming a group of individuals into an intelligent collective 🤝🧠

The problem with this conversation is that people dont distinguish between "sex" and "sexual phenotype". The first, as Ed explains, is not actually a property of an individual, but rather a set of options in an evolutionary game theory setup. There are indeed only two of these sexes (in mammals)

Very disappointed that we were forced to cancel our field season and return early, following the suspension of our NSF grant as part of Trump’s attacks on UCLA. Particularly sad for our students, who spent significant time and effort to join us this year.
