> I like HackerNews because the conversations are mostly intelligent and polite

Comment sections like this one highlight the risks of mistaking comments that look intelligent and polite for authority. The number of confident, polite posts in this comment section that are giving out factually incorrect information is incredible. Someone down below was speculating about this drug’s cardiotoxicity in ways that could be dismissed within 15 seconds of reading the Wikipedia page, but they presented their speculation as if it had an air of scientific authority.

The number of commenters trying to suggest that psychedelics, which do not interact with the 5-HT4 receptor studied in this article, are a substitute for this drug or otherwise should be used for this indication is astounding.
