Honored to contribute a Journal Club piece to @natrevpsychol.nature.com!

I explore Robert White's seminal "competence motivation" framework (1959) and why it remains relevant over 60 years laterβ€”from why toddlers insist on doing things themselves to designing intrinsically motivated AI. πŸ€–

Forget modeling every belief and goal! What if we represented people as following simple scripts instead (i.e "cross the crosswalk")?

Our new paper shows AI which models others’ minds as Python code πŸ’» can quickly and accurately predict human behavior!

Timely reminder that 'associative' language leads lay people to confuse correlation and causation, as @tomerullman.bsky.social and I showed a few years ago.

The threat of analytic flexibility in using large language models to simulate human data: A call to attention Social scientists are now using large language models to create "silicon samples" - synthetic datasets intended to stand in for human respondents, aimed at revolutionising human subjects research.

Can large language models stand in for human participants?
Many social scientists seem to think so, and are already using "silicon samples" in research.

One problem: depending on the analytic decisions made, you can basically get these samples to show any effect you want.

Our new paper is out in PNAS: "Evolving general cooperation with a Bayesian theory of mind"!

Humans are the ultimate cooperators. We coordinate on a scale and scope no other species (nor AI) can match. What makes this possible? 🧡

How to cooperate for a sustainable future? We don't know (yet), but I'm thrilled to share that our new perspective piece has just been published in @pnas.org. Bridging complexity science and multiagent reinforcement learning can lead to a much-needed science of collective, cooperative intelligence.

Across 9 experiments (+6600 participants), we explored a paradox: How do non-experts judge scientific explanations they can’t fully understand? We found that scientific jargon can increase people’s satisfaction with explanations, even though it makes them less comprehensible.

Analysis | AI firms say they can’t respect copyright. These researchers tried. A new effort using only openly licensed data may have implications on thorny policy disputes around copyright and AI

A lot of people say generative AI shouldn't infringe on copyright. These researchers actually tried to do it. The result: an 8 terabyte dataset of text that's openly licensed or in the public domain & 7 B parameter model that performs as well as Meta's Llama 7B www.washingtonpost.com/politics/202...

"Physics vs. graphics as an organizing dichotomy in cognition"

The sub specifically bans bots and LLM-generated responses.. and at one point it was "acting as a trauma counselor specializing in abuse"?? Definitely unethical, also given how common bots are, they had no way of controlling if they persuaded real people or other bots in their results 🫠
