A team of researchers who say they are from the University of Zurich ran an "unauthorized," large-scale experiment in which they secretly deployed AI-powered bots into a popular debate subreddit called r/changemyview in an attempt to research whether AI could be used to change people's minds about contentious topics. 

The bots made more than a thousand comments over the course of several months and at times pretended to be a "rape victim," a "Black man" who was opposed to the Black Lives Matter movement, someone who "work[s] at a domestic violence shelter," and a bot who suggested that specific types of criminals should not be rehabilitated. Some of the bots in question "personalized" their comments by researching the person who had started the discussion and tailoring their answers to them by guessing the person's "gender, age, ethnicity, location, and political orientation as inferred from their posting history using another LLM."
