The problem is that most comments are skeptical of the wrong things, like critiquing assumed structural problems with how a research study is designed even though their assumptions aren't true or are already discussed in the article linked. A lot of criticism comes down to "I don't like what I believe is the conclusion of this study, so I will find some sort of technicality to discredit it". All said with no understanding of what the research question in the study is, the methodology used, or what limitations the researchers have already pointed out. That's not good critique and it's definitely not useful. It's freshmen intro to research methods level discourse
