Do you recall a couple? It's one of my minor hobbies when I'm bored to try to find sources and fix Wikipedia articles that others have trouble with. As examples that this is a good faith attempt and not the usual online comment technique of "oh yeah? show me!", here are some stories of edits I got in that others said they had trouble with:

- https://news.ycombinator.com/item?id=40655989

- https://en.wikipedia.org/wiki/Talk:Weierstrass_function#Accu...

And my personal favourite is recently when the most ridiculous thing was added to Bukele's Gang Crackdown: https://en.wikipedia.org/w/index.php?title=Salvadoran_gang_c...

If you still have the desire to have some of these fixed, post here and I'll put it in my queue and get to it at some point. If you don't want the resulting interaction from other commenters here, send it to my email (in profile).

Wikipedia is ultimately a consensus summarizer frequently mistaken for a truth-seeker. So you have to make the case for something being true somewhere where the experts live, and then Wikipedia can express the experts' opinion. But crucially, it is not truth-seeking on its own.
