My students, collaborators, and I completed a large scale project examining the effects of a single dose of intranasal testosterone on economic preferences (N = 1,000 men). @gidin @corenapicella @francescarlub @NipissingU #testosterone https://t.co/hOdmEHusWY

Interested in #HBES2026 in Rabat? The hosts have drafted a FAQ regarding the location: https://t.co/ttlr7qIq3H Overall, this is an exciting opportunity for a great location, hosted by a great team, joint with another evolutionary society, and with perspectives we seldom hear

#HBES2026 will be a joint meeting with the Cultural Evolution Society in Rabat, Morocco: CES is May 11-13, HBES is May 13-16, with one day of overlap. It’ll be a great chance for cross-pollination between the two evolutionary societies. Come for one conference, stay for both!

In plenary #HBES2025 #3, Jim Roney declares war on the “parsimony-based” approach he claims dominates hormone research, i.e., attempts to find the “one” true effect of a hormone, which leads to imbalances in research on inputs vs outputs, obscures functions & creates confusion

3) Roney's #HBES2025 plenary yields fresh insights: He provides the 1st evidence of estradiol & progesterone coordinating to suppress sexual desire during the "implantation window" & shows how this makes sense of seemingly conflicting effects of oxytocin

I could have never conceived that the U.S. President would be far more aggressive against a great university than he would be against a Russian dictator engaged in invading a U.S. ally. Why is it smart to starve cancer research, students on financial aid, innovation in public

Harvard has set an example for other higher-ed institutions – rejecting an unlawful and ham-handed attempt to stifle academic freedom, while taking concrete steps to make sure all students at Harvard can benefit from an environment of intellectual inquiry, rigorous debate and

🚨 New WP🚨 (w/ @corenapicella @CBicchieri @DStibbardHawkes et al.) Using a variant of @Econ_4_Everyone’s take-or-give DG, we examine altruism & fairness concerns among Hunter-Gatherers and find fascinating nuances. Detailed results👇🏻 🔗 https://t.co/Rphu9QCDVa

1. What's at risk by disrupting NIH? With only a bit of hyperbole: a mechanistic understanding of life itself, & therefore better treatments for cancer, dementias, autoimmune disorders, neurodegenerative diseases, birth defects, aging & more. Notes on a revolution interrupted 🧵

🚨 Paper alert! 🚨 It’s common for cross-cultural research to be conducted in a second language: a national majority language or lingua franca. But research among the Hadza, published today in @PNASNexus, shows second languages can bias results. 🧵/14 https://t.co/xpF2y8Bc8I

HBES is pausing our General Funding Grants. As described at #HBES2024, Elsevier plans to reduce our royalties, leaving us less money to fund subsidiary activities. Negotiations are ongoing; we will inform everyone if/when we can resume these grants. Apologies for inconvenience

Are religious people really more prosocial? @jmkelly91, @_StephKramer and I spent years meta-analyzing the massive amount of research on this question. Synthesizing over 700 effects spread over 60 years of study, the answer looks very much like a "yes". Thread🧵...

Here’s the big HBES news! 🙌We want to get students access to evo training!🙌 Awardees receive $ + social support, mentorship + research training—including support to attend + present work at the 2025 HBES Conference. Apps due June 1! Help us broaden the evo world by RTing!!

Nature just published an article that might be useful to any HBES members finishing their degree (or with students finishing): How to land a scientific position even in a struggling economy ( https://t.co/sK6RtO3Jt4)

The science of cooperation shows we can coexist peacefully, argues @mmuthukrishna. Yet, he warns, “because the scale of cooperation is now in the hundreds of millions, if not billions, the consequences of potential conflict is higher than it’s ever been.”
