This is pretty common on HN but not unique to it. Lots of rationalist adjacent content (like stuff on LessWrong, replies to Scott Alexander's substack, etc) has it also. Here I think it comes from users that try to intellectualize their not-very-intellectual, stream of consciousness style thoughts, as if using technical jargon to convey your feelings makes them more rational and less emotional.
Thank you. I find this type of thing really interesting from a psychological perspective. A bit like watching videos of perpetual motion machines and the like. Probably says more about me than it does about them, though.
Unfortunately this kind of talk really gets under my skin and has made me have to limit my time on this site because it's only gotten more prevalent as the site has gotten more popular. I'm just baffled that so much content on this forum is people who seem to think their feelings-oriented reactions are in fact rational truths.
