X’s algorithm learns what you hate and shows you more of it, according to a new study just published in the Proceedings of the National Academy of Sciences (PNAS). The paper, titled Value misalignment of X’s feed algorithm is a reflection of value tensions in engagement, found that the site’s algorithm prioritized engagement above all else when it generated a user’s For You Page. It also showed that X serves more ragebait to people who say they are Democrats, although the exact reason for that is unclear.
Why? “Engagement”:
When a user on X sees a post that makes them mad — like a press release from a politician from a political party they don’t like — sometimes they’ll fight about the post in the replies. It doesn’t matter who you follow or what your stated values are, X reads replying as engagement and will send more of the infuriating posts the user’s way.
A comment from X’s former head of product, Nikita Bier, suggests this was once true but now isn’t:
“This is no longer true,“ Bier said in a post on X. ”The largest contributor of seeing ragebait was the reply predictor and we were aware that angry replies were causing people to see more of that content. So last month, we gave the reply predictor a 15x boost if it’s a friend’s post — and it reduced ragebait by [an] order of magnitude."
Bier left that role two weeks ago after a mere 13 months. For all I know, this change led to his departure and was reverted the minute his badge stopped working. Regardless, you know how else you can reduce X/Twitter ragebait? Leave X/Twitter.
