New: AI chatbots can change voters' minds, according to a pair of in-depth studies published just now in Science and Nature. How they do it is interesting — and concerning. Gift link: wapo.st/49RSstP

Ahead of the 2024 U.S. election, researchers at MIT, Cornell et al. asked more than 2,000 Americans to converse with chatbots that were told to advocate for either Trump or Harris. 1 in 25 participants were persuaded to shift their likely vote. Outside the U.S., those figures were higher.

Researchers tested several ways to train the AI chatbots to persuade people. The most effective tactic turned out not to be pyschological manipulation, but simply addressing voters' concerns one-by-one by presenting a ton of factual claims. Troublingly, that worked even when the claims were false.
