My first paper, out in PsychReview!! Along with @orbenamy.bsky.social, Nik & @jaeggiadrian.bsky.social, @realadamhunt.bsky.social & I revisit an old theoretical question using concepts from evo psychiatry and anthro: Why do mixed associations exist b/w social media & mental health? A 🧵

Why we strike: Bargaining as an expression of human cooperation. Dr @kristensyme.bsky.social considers labour action, and draws parallels with family conflict… www.bps.org.uk/psychologist...

"After nearly 40 years, the Arctic Research Consortium of the United States, or ARCUS, will close September 30." "The Arctic Research Consortium of the United States funded programs that aided Indigenous communities and tracked melting sea ice, among dozens of initiatives."

📝 Writing Wednesday! Ph.D. Candidate Michael Gaffney first-authored an article on on how children communicate their needs through crying. This research was recently published in Human Nature, and his photo taken in Utila, Honduras made the cover image! Article: link.springer.com/article/10.1...

Colleagues based at UK universities: please sign and share this letter to support Gazan students coming to study in the UK, in order to request Governmental deferral of the biometric data requirement and safe evacuation.

Challenging alpha male’ norms: new study across #primates reveals that power relationships between males and females are less clear-cut than expected. An intl. team including D. Lukas @mpi-eva-leipzig.bsky.social shows that context matters for which sex has power www.mpg.de/24986976/063...

Our paper in @natcomms.nature.com, we show how cognitive maps in the hippocampal system could solve the general problem of representing and relating multiple alternative action plans.  doi.org/10.1038/s414... With @doellerlab.bsky.social, Patrick Haggard, @vigano.bsky.social, Daniel Reznik

Here's the run down of my talk at #EHBEA2025 entitled 'Analysing the Form and Function of Rituals Using Large Language Models: Fasting'. I illustrate how we can use LLMs to measure the constituent properties of rituals across ethnographic texts to test theoretical models on a large-scale.
