People are more likely to comment when it worked and upvote comments that give them hope.

Uh, do you remember what youtube comments were like 2016-ish and earlier?

It seems obvious to me the overall experience of youtube comments is much more dependent on youtube's choices than people's behaviors.

That's just not how people work.

Good point this could have been better phrased. I think I meant more like "In regards to health, my impression is people talk more about things that worked for them even if they're false positives (placebos, regression to mean etc) than they do about true negatives (things that didn't work)."

(This is different than other things like online reviews for products which are more biased towards negative experiences.)
