> I’ve been around a lot of bullshitters my whole life, and my immediate reaction is to go “this person is full of shit, not worthy of my attention, kthxbye”

I have something like that, but not (just?) for people. When I read (or listen to) something I very often fairly quickly recognize meta signs of bs and go 'kthxbye'. I call it bullshit filter and I am often surprised that some, even fairly intelligent, people can have suprinsingly weak one. As for morbid curiosity towards bs, I have very little. I'm even afraid that being too curious about it might be detrimental so I'm keeping my distance even when I engage somewhat.
