The algorithm would analyze the post's/user's likes. If a post/user is liked by people who often disagree, then boost the engagement of that post/user. If a post/user is liked by an echo chamber, then deboost it.

What you describe is a flamewar maintenance algorithm. I mean, it COULD work if all people were sound and reasonable, but that's obviously not the case. And being a flamewar battleground is probably not the goal of most platform owners either. Also, for many topics that are not politics you don't need disagreement for a productive discussion.

But community notes works well. That's evidence that reasonableness emerges when you boost content that a diversity of people appreciate, regardless of whether people are sound and reasonable.

Are you saying my idea will increase flamewars? I believe it should decrease flamewars, and that's why I want to see it implemented. Again I point to community notes. If a diversity of people like content, it's probably level-headed, and that's why community notes works so well.

Ok, now I get it, I got it wrong. Still questionable, but for other reason: niche content (like, retrocomputing or pet spider care or just about anything that's less agreeable than funny kittens) would never come thru.

Echo chambers aren't intrinsically bad, only when it's about politics and social issues - i. e. stuff that will affect everyone in the end.
