Most people are overconfident even in the face of extensive, objective performance feedback: "Overconfidence persists in tournament chess, a real-world information environment that should be inhospitable to it." pubmed.ncbi.nlm.nih.gov/40808249/

We also found that people often endorse general rationing policies that contradict the specific choices they would make when presented with hypothetical patients. They also prefer not to incorporate factors like patient race, sex, education, and income when creating a policy.

We found that people's choices of which patient should get a treatment can be influenced by the presence of irrelevant extra patients (an example of the attraction effect). This occurred for both laypeople and clinicians when considering ventilator assignment.

Clay Shirky on the impact of generative AI on learning: "As with calculators, there will be many tasks where automation is more important than user comprehension, but for student work, a tool that improves the output but degrades the experience is a bad tradeoff."

Rooting out scientific fraud and deception is one of the most important things scientists can do. Finally, an authoritative guide!

Now that LLM-based AI tools can analyze data on their own, @chiraag.bsky.social decided to test whether they notice the gorilla, or whether they also seem to experience inattentional blindness—like humans who fail to notice the "invisible gorilla" that @profsimons.bsky.social and I wrote about ...

A fun 2020 paper by @itaiyanai.bsky.social and Martin Lercher found that many students who were given a data set to analyze, along with specific questions to answer about it, failed to notice that a scatterplot of the points formed an image of a gorilla. But can AI models spot the gorilla? ...

I've been waiting for the answer to this question for a long time, but if I could have just one wish, it would be for people to stop mixing their large mammal business metaphors by saying "that's the invisible gorilla in the room."

Pleased to see that the Yale Peabody Museum has included the invisible gorilla (by @profsimons.bsky.social and me) in their new exhibit on perception, attention, and memory! Other museums that have exhibited our work: American Museum of Natural History, Exploratorium, Wellcome Collection, & MONA.
Peabody Museum opens new neuroscience exhibit
The exhibition, entitled “Mind/Matter: The Neuroscience of Perception, Attention and Memory,” explores the history of neuroscience and the wonders of human cognition.

I'm thrilled that our paper on base-rate neglect (BRN) and on-the-job experience (w/ @cfchabris.bsky.social and @michellemeyer.bsky.social) was just accepted at Management Science!

TLDR: on-the-job experience with base-rate type problems mitigates, but does not eliminate, base-rate neglect.
