Nice article by Kevin Munger (based on @sgonzalezbailon.bsky.social et al.'s paper on FB polarization and @jongreen.bsky.social et al.'s paper).

Our new piece in Nature Machine Intelligence: LLMs are replacing human participants, but can they simulate diverse respondents? Surveys use representative sampling for a reason, and our work shows how LLM training prevents accurate simulation of different human identities.
Encyclopædia Britannica will continue to use ‘Gulf of Mexico’ for a few reasons:

-We serve an international audience, a majority of which is outside the U.S.

-The Gulf of Mexico is an international body of water, and the U.S.’s authority to rename it is ambiguous.

💥 Mark Zuckerberg’s Immoderate Proposal 💥 (via @sgonzalezbailon.bsky.social and @davidlazer.bsky.social)

Researchers are "skeptical" the new system will slow the spread of misinformation and "anticipate [Meta's policy changes] will cause a flood from some Pages."

Based on their research, David Lazer and Sandra González-Bailón anticipate that Meta's elimination of penalties for sharing misinformation will cause a flood from some Pages– which are still the most effective means to spread content on Facebook.
