there was some discussion on here recently about the scientific legitimacy of cognitive dissonance research. as someone who has spent years investigating this literature, i wanted to make a thread to explain why pessimism is not justified by careful inspection of the evidence

There’s growing evidence that something was going seriously wrong in the classic early work on cognitive dissonance

Latest revelation: The story in When Prophecy Fails seems to have been fabricated in the most egregious way

But this is not the only one…

Debunking “When Prophecy Fails”
In 1954, Dorothy Martin predicted an apocalyptic flood and promised her followers rescue by flying saucers. When neither arrived, she recanted, her group dissolved, and efforts to proselytize ceased....

It was so great! Really lucky to have been able to listen and learn from Barbara, Liuba, & Benedek. Some of the most insightful research happening today, from just the absolutely nicest, coolest people.
Heading for my last day of the ESPP in Warsaw. Amazing to see philosophers and psychologists in one room. It was a privilege to talk about how symbols and compositionality emerge in babies alongside @ljubapi.bsky.social and @benedek.bsky.social 💕 to @ericman.bsky.social for organizing the symposium!

Bob Clark for mayor
Bob Clark, VP of marketing for Herr Foods, Inc., said the company was surprised to see it was mentioned in the press.

“While we can’t speak to the details of the story,” he said, “we can confirm that our Sour Cream & Onion flavor is money.”

Hard to think of a better gig. So cool for Cornell too
Apply for funding to work with me and Gord at Cornell!
Interested in doing a postdoc with me & @dgrand.bsky.social? Consider applying to Cornell's Klarman Fellowship: as.cornell.edu/research/kla...

It involves a competitive internal application process, but it's 3 years of funding @$80k/year

Please email me/Dave if you're interested! Oct 15th deadline

A key takeaway from 20+ years of computational RL is: model-free=automatic, model-based=deliberate. My new paper w/ @benedek.bsky.social challenges this view, suggesting that MB algos are more ubiquitous, & automatic processing more sophisticated, than currently thought: www.pnas.org/doi/10.1073/...
