Psychology research finds people are often overconfident. Open questions in that work that were addressed in a cool paper studying tournament chess players. My latest for @psychtoday.bsky.social with a shout-out to @cfchabris.bsky.social and Daniel Simons.

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