When people post online, they usually declare their opinions. And in social media echo chambers, those opinions tend to be validated.

But the subreddit r/ChangeMyView *might* be the only place on the Internet where people come in good faith to have their opinions challenged — and perhaps even changed.

Topics range from movie fandom to food preferences to history to some of the most challenging ethical and political discussions of our time: abortion, global conflict, mental health, and of course our current U.S. leadership.

Someone posts their view, and commenters present their challenge. If the original poster is swayed — even slightly — they award a "!Delta" for the change. The result is a bastion of civil discussion about emotional and challenging topics, and the community of 4 million subscribers is held together by precise rules and moderation.

But in April, the University of Zurich conducted a social experiment on the subreddit shook the community to its core, and begs the question: Can AI be weaponized to change the views of millions on the Internet? And if so, how can we study that problem ethically?

This week, Logan MacGregor, a moderator of r/ChangeMyView, joins Matt to discuss what makes this community so special, and how it responded to this shocking experiment that violated its core tenets.
