Like millions of others, Gordon Pennycook’s older brother has leapt down the rabbit hole of conspiracy theories, and Gordon says he’s tried to change his brother’s mind, without success. Which tracks, if you’ve ever debated a conspiracy theorist — it can feel impossible to pull them back to reality.

If anyone was qualified to convince his brother, though, it’s Gordon, who’s a psychology professor at Cornell University where he studies why people believe things that aren’t true. So Gordon wanted to put this question to the test: Is it actually the case that conspiracy theorists rarely change their minds? He and a team of researchers ran an experiment using an AI chatbot to rebut people’s theories. And the results were very surprising. In fact, they ended up changing Gordon’s mind about conspiracy theories, and the people who believe them.
