Researchers secretly experimented on Reddit users with AI-generated comments

A group of researchers covertly ran a months-long "unauthorized" experiment in one of Reddit’s most popular communities using AI-generated comments to test the persuasiveness of large language models. The experiment, which was revealed over the weekend by moderators of r/changemyview, is described by Reddit mods as “psychological manipulation” of unsuspecting users. “This experiment deployed AI-generated comments to study how AI could be used to change views.”The researchers used LLMs to create comments in response to posts on r/changemyview, a subreddit where Reddit users post (often controversial or provocative) opinions and request debate from other users. The community has 3.8 million members and often ends up on the front page of Reddit. “People do not come here to discuss their views with AI or to be experimented upon,” the moderators wrote.
