I’ve found the more I know about the topic at hand, the more wildly many of the comments seem off base, even the highly upvoted undebunked ones. Its harder for me to judge topics I don’t know much about, but I have to assume it’s something similar.
That is true for articles as well though, I find comments typically have better info than the articles. It is more likely for some of the comments to have been written by real experts than that the article is.
Especially if somebody is being wrong.
