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.

more than 1,700 comments made by AI bots

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.

The experiment was revealed over the weekend in a post by moderators of the r/changemyview subreddit, which has more than 3.8 million subscribers. In the post, the moderators said they were unaware of the experiment while it was going on and only found out about it after the researchers disclosed it after the experiment had already been run. In the post, moderators told users they “have a right to know about this experiment,” and that posters in the subreddit had been subject to “psychological manipulation” by the bots.

I remember when my front page was nothing but r/changemyview for like a week and I just unsubscribed from the subreddit completely because some of the questions and the amount of hits felt like something fucky was going on. Guess I was right.

Same happened to the relationshipsadvice and aita subreddits, the number of posts suddenly skyrocketed with incredibly long, overly-detailed stories that smacked of LLM-generated content.

[-] besselj@lemmy.ca 32 points 1 week ago

It'll be interesting to find out if this research got IRB approval prior to the study

[-] NOT_RICK@lemmy.world 10 points 1 week ago

I hope for the sake of their careers they did

[-] finitebanjo@lemmy.world 3 points 1 week ago

Given the highlighted positions the bots took, I'm not sure we should worry about their specific careers ending.

[-] TwinTitans@lemmy.world 21 points 1 week ago

That’s place is mostly bots anyway, I’m sure no one noticed.

[-] ByteJunk@lemmy.world 2 points 1 week ago

Why you gotta call me out like that

[-] ijedi1234@sh.itjust.works 2 points 1 week ago

It's like the MMO Erenshor. Every player other than yourself is a bot pretending to be a human being.

[-] nectar45@lemmy.zip 19 points 1 week ago

Ok maybe I dont miss reddit after all...

[-] notabot@lemm.ee 10 points 1 week ago

It'd be pretty trivial to do the same here, 1700 or so comments over 'several months', is less than 25 a day. No need even for bot posting, have the LLM ingest the feed, spit out the posts and have the intern make accounts and post them.

[-] nectar45@lemmy.zip 1 points 1 week ago

Well at least this place is exclusively where people who got banned from reddit end up so they will struggle to find us at least....

[-] notabot@lemm.ee 2 points 1 week ago

Hey, I didn't get banned (yet), I just prefer the vibe here.

[-] turtlesareneat@discuss.online 1 points 1 week ago

I created my account to have one ready, then when I got banned, it was easy to hop over

[-] ogmios@sh.itjust.works 18 points 1 week ago

I remember the good old days when the NSA had to physically fly an airplane over the border and spray one of our towns with chemicals if they wanted to run psychological experiments on people!

[-] RightHandOfIkaros@lemmy.world 17 points 1 week ago* (last edited 1 week ago)

To be fair, I can see how it being "unauthorized" was necessary to collecting genuine data that isn't poisoned by people intentionally trying to soil the sample data.

[-] Maeve@kbin.earth 8 points 1 week ago

This is straight up unethical, at best.

[-] DrBob@lemmy.ca 13 points 1 week ago* (last edited 1 week ago)

...posters in the subreddit had been subject to “psychological manipulation...

There are no users there. It's just bots talking to other bots.

[-] PumaStoleMyBluff@lemmy.world 11 points 1 week ago

This is what should get departments defunded, not DEI 🫠

[-] AmidFuror@fedia.io 6 points 1 week ago

If you think this is shocking, just wait for the big reveal about r/StanfordBasement.

[-] RememberTheApollo_@lemmy.world 5 points 1 week ago

Gotta love the hollow morality in telling users they’ve been psychologically manipulated this time but yet do nothing about the tens of thousands of bots doing the exact same thing 24/7 the rest of the time.

[-] BoxOfFeet@lemmy.world 2 points 1 week ago

Right? The only difference here is that they fessed up.

[-] dukeofdummies@lemmy.world 3 points 1 week ago

... well how many deltas did it get?

I hate it as an experiment on principle but c'mon how well did it do?

[-] dukeofdummies@lemmy.world 3 points 1 week ago

Found it, 137 deltas.

Impressive, a bit worrisome

[-] renamon_silver@lemmy.wtf 2 points 1 week ago

Ah, to freely give away my data to a corporation whilst acting as a lab rat...

[-] LarmyOfLone@lemm.ee 1 points 1 week ago* (last edited 1 week ago)

r/changemyview is one of those "fascist gateway" subs, or at least one of the subs that I suspect as that. The gateway works by introduing "controverial" topics which are really fascist but they get upvote because "look at this idiot!". But slowly it moves the overton window and gives those people who actually do believe in inequality a space to grow in. Opinions that are racist, anti-feminist, anti-trans, ultra-nationalist, authoritarian or generally against equality and justice.

Reddit was slowly boiled over the last decade like a frog.

And you can be absolutely sure that not only researchers are researching this for science, there are plenty of special interests that do this. It really started with climate change denial.

[-] lmmarsano@lemmynsfw.com 1 points 1 week ago* (last edited 1 week ago)

they get upvote because “look at this idiot!”

seems like a great reason: upvoted

[-] BilboBargains@lemmy.world -1 points 1 week ago

What difference does it make if you're talking to a bot? We never meet our interlocutors anyway. Would these people have the same reaction if it were revealed they were talking to a role playing person because I'm pretty sure we've already done that many times over.
