Interesting!

The bacteria in your gut depend on where you are in the social network. And the microbes within us treat our social networks as the extended environment in which they thrive. They can spread from person to person. New #HNL work out today in nature. 1/

So happy to be a part of this project together with Natalia Frankowska and @A_Galbarczyk 🎉 rdcu.be/d4WL5

Why do genes for gay-ness persist? (It's more complex than that, but...) A large, pre-reg study tested the 🧬sexually antagonistic genes🧬hypothesis: Gays have ⬇️kids, but related genetic variation persists *BECAUSE GAYS' SIBLINGS* have ⬆️kids > straights'. True? Unlikely...

I posted about the Feb 3 abstract deadline for the International Society for Evolution, Medicine, and Public Health July meeting in Nashville but only a few have seen it... perhaps academics and scientists are all elsewhere now. Please repost-and submit! isemph.org

Excited to share this new publication on the emotion of disgust, co-authored with my awesome former grad students: rdcu.be/eaI6k

Does a history of infectious diseases shape how we perceive our health? Our preliminary study finds mixed evidence across countries. Some analyses suggest a small positive effect, but overall, no clear link [link to the paper below] @ Amazing Large-Scale Cross-Cultural Team!

1. The Santa Barbara school of evolutionary psychology holds that a universal set of complex psychological adaptations evolved in Pleistocene Africa. In no particular order, here are few folks on here doing research in this tradition, highlighting one paper/thread each:🧵

Dunbar's hugely influential social bonding hypothesis for the evolution of human language, music, & dance is based on the putative increase in primate grooming time with group size. These are the supporting data, including a confound with substrate pointed out by others: 1/3

Are you a student or professor in psychology -- or any of the social sciences? If so, you've definitely seen this mistake before. It's all over the textbooks and journal articles. You might have seen it formulated in any of these ways: - Is that behavior evolved or learned?

This summer, August 31st, we are hosting an evolutionary psychiatry debate in Cambridge. Experts discussing whether depression is functional and whether evolutionary perspectives are more important in research or the clinic. Audience participation possible. Join us!

1/ Are people who meet their partners online LESS satisfied in their relationships than those who meet offline? Our new study across 50 countries (N = 6,646) suggests: Yes. Individuals who met their partners online reported LOWER relationship satisfaction and love.

Too often, I see people talk about a replication as if the first study has established something, and the replication study is a double-check. What people often fail to understand is that we do not do replication studies to *check* a finding, but to *establish* a finding. 1/x
