💙New paper!💙 How is knowledge transmitted across generations in a foraging society? With @danielredhead.bsky.social we found: In BaYaka foragers, long-term skills pass in smaller, sparser networks, while short-term food info circulates broadly & reciprocally academic.oup.com/pnasnexus/ar...

Are you studying animal sociality? Confused about the "non-independence" of social network data: what on earth are they? are they threatening your results? should you attempt to get rid of them? A thread summarising a part of our new paper (ecoevorxiv.org/repository/v...).

Important preprint by @pietronickl.bsky.social @msultan.bsky.social Caedyn Stinson, @fstock.bsky.social Ralph Hertwig @anaskozyreva.bsky.social, touching so many points to move the misinfo discussion forward, like feedback-loops, systemic factors and rhetoric, great work! osf.io/preprints/so...

New in TiCS w @dgrand.bsky.social @gordpennycook.bsky.social It’s been ~10yrs since misinfo research exploded but our paradigms are stuck in the post-2016 “fake news” model Time for new approaches: o True/False → Content that misleads o Belief → Behavior o Eval interventions in ambiguous settings

Can we turn a science fiction thought experiment into an actual experiment? Check out our new @nature.com paper on the "Science Fiction Science" method (summarized by @jfbonnefon.bsky.social below)

New paper alert 📢📢: study from @taichimpproject.bsky.social shows that young chimpanzees peer more at individuals performing more complex food extraction and they peer more at those who are knowledgeable. Chimpanzees learn from others about extracting their food ... www.nature.com/articles/s42...

With 17 days to go until the US takeover by the new Trump (or Musk?) administration, I thought it might be worthwhile to share a number of recent papers published by our team that counter arguments that have been leveled against misinformation research. 1/n

If you hide people's wealth, you can make the widely observed economic gradient in happiness go away, in part by making poor people relatively happier. This 2022 experiment via @natureportfolio.bsky.social shows these somewhat dispiriting results. www.nature.com/articles/s44... 1/

Social contagion is a powerful force. People copy thoughts, feelings, & actions of those to whom they are connected. Understanding social network structure & function makes it possible to use social contagion to intervene in the world to improve human welfare. www.science.org/doi/10.1126/... 1/
