Why do some ideas spread widely, while others fail to catch on?

Our new review paper on the PSYCHOLOGY OF VIRALITY is now out in @cp-trendscognsci.bsky.social (it was led by @steverathje.bsky.social)

Larger scientific teams produce more impactful breakthroughs + patents

I wrote a paper with 4 principles to optimize large scientific collaborations based on the science of cooperation & collective intelligence: osf.io/preprints/ps...

And a substack summary: powerofus.substack.com/p/four-princ...

🚨New preprint🚨

osf.io/preprints/ps...

In a sample of ~2 billion comments, social media discourse becomes more negative over time

Archival and experimental findings suggest this is a byproduct of people trying to differentiate themselves

Led by @hongkai1.bsky.social in his 1st year (!) of his PhD

I am happy to announce that our project on risk and social learning is now in press at Psychological Review. Several new additions and revisions thanks to detailed feedback from colleagues and anonymous reviewers. osf.io/preprints/so...

Everytime I visit a European country that turned the world upside down, colonized millions and whatnot for *spice*, I just have one question: what did y'all do with that spice....???? Because it ain't in the food????

Fun article about “outsider” scientists and their breakthroughs.

“Academia filters most funding, publishing, and hiring decisions through senior insiders, which favors ideas within existing paradigms.”

Can one bring together Reinforcement learning and Drift Diffusion models to understand collective foraging ?

Congrads to Jonathan Marienhagen , Lisa Blum Moyse and Dominik Deffner on this new study. Very happy that I was part of this collaboration.

Rituals as a stag hunt game?! To the top of the reading list! 🤩

The TiCS issue featuring our paper on "A timeline of cognitive costs in decision-making" is now available online 😄

New paper with @mujianing.bsky.social & @prestonlab.bsky.social! We propose a simple model for human memory of narratives: we uniformly sample incoming information at a constant rate. This explains behavioral data much better than variable-rate sampling triggered by event segmentation or surprisal.

New preprint from @tobyhandfield.bsky.social and me!

We analyze authorship order norms from two perspectives: (1) why do disciplines have different norms and (2) do those different norms affect what kinds of collaborations take place.

A few months ago, Nature published how-to guide for using ChatGPT to write your peer reviews in 30 minutes.

This is, of course, a horrible idea. Here’s my response with @jbakcoleman.bsky.social .

this is BEAUTIFUL!

Super excited for our CogSci paper on the dynamics of conversation led by @helen-schmidt.bsky.social and @clairebergey.bsky.social !

New paper!

Managing speed-accuracy tradeoffs is an important part of commonsense psychology. But how do we do it in groups, where no single person controls decision speed?

The two teams below need to make a decision — and it probably feels obvious that the green team will take longer.

But why?

People not only form social networks, they construct mental maps of them. People think about the ties between other people, including ties among individuals to whom they are not themselves directly connected. These “cognitive social networks” have rarely been studied. 1/

Congrats :))

This is fantastic, causal work demonstrating the basal ganglia’s role in explore-exploit decision making www.nature.com/articles/s41...

"One obvious lesson from all this is that, rather plausibly, we today have some convictions and conceits that educated people of the future will label as crackpottery."

Big cities are vibrant hubs of culture, but why exactly is that? Now out in @natcomms.nature.com, we analysed music listening patterns of over 2.5 million people and demographics to examine mechanisms driving cultural diversity. With @researchdeezer.bsky.social @norijacoby.bsky.social
