The project I've been working on since Day 0 of grad school is finally published! We find that ecology explains a decent chunk of cultural variation-- across 66 different cultural variables royalsocietypublishing.org/d…

In those cases, the result is not an "infodemic" but what I have elsewhere called a "marketplace of rationalizations" in which misinformation behaves more like a consumer good than a contagious virus. cambridge.org/core/journals/…

Is misinformation a dangerous virus? Are we living through an infodemic? Is there a vaccine for misinformation? In this review of Sander van der Linden's (@Sander_vdLinden) new book 'Foolproof', I argue that the answer to these questions is "no". A thread:

"[R]eligious narratives, though false or seemingly irrational, often turn out to reflect concerns about behaviors that matter for people's livelihoods. With radical uncertainty, they are often all we have."

In need-based sharing, sharing is more important than need

Aaron Lightner retweeted
Need is central to many models of human cooperation including need-based sharing: asking for help only when in need & sharing when asked. But it ends up that even if individuals ask when *not* in need, sharing can still enhance survival for all involved 1/

New theory paper on the sociocultural dynamics of medical technologies: I show that when individuals can entertain multiple treatments simultaneously, both ineffective and effective medical treatments may stably coexist:

How do people intervene in a dynamic system to learn its causal structure?🔧⏰
In this new Cogn Psych paper, we found people generate causal events that are both informative and simple to interpret. W/@tobigerstenberg, Ralf Mayrhofer, and @NeilBramley

This is such a cool paper.
Elegant evidence that children sample one possibility out of many and treat it as actual.

All models are wrong, and some are religious: Supernatural explanations as abstract and useful falsehoods about complex realities

New preprint with @AnnePisor & @ed_hagen: psyarxiv.com/cm3ap
🧵: Models of cooperation often highlight that sharing is esp. useful for risk pooling when recipients actually need help
But how strictly does this need-based sharing rule map onto real-world traditions?
/1
So although need-based sharing is important, the cost of failing to share when someone needs help greatly outweighs the cost of sharing with someone who doesn't
In fieldwork, we also observed people behaving in a way that seems sensitive to these different costs
/9
There are, of course, many assumptions, alternatives, caveats, etc. that we also discuss in the paper
