Does AI improve or undercut academic scholarship?
A new study finds that academics who use AI increased both the quantity & quality of their academic scholarship and it appears to reduces inequality (helping junior and non-english speaking scholars the most).

Social scientists should not use chat interfaces when using LLMs in their research: they are impressively inefficient, and obscure/impose important methodological decisions that require thought.

Psychological inoculation is a very popular intervention against online misinfo, but it hasn't been tested using real-world outcomes in realistic scenarios.
In a new paper just published in PNAS Nexus, this is what we did: academic.oup.com/pnasnexus/ar...
Short version: It didn't really work.
