He ought to therefore update his beliefs about physicists.

He already did.

I don't find it particularly interesting but thought other people might.

much later edit (revisiting after years):

In fact I literally posted this because someone told me lesswrong was quite tribalistic and status oriented,so they didn't want to post this thing they'd found, and i didn't believe it. I had the impression that if it was posted no one would blink an eye, and people would be straightforwardly pleased to have something self-critical (where "self" here is lesswrong) to analyse, so I said I'd post it myself. That was literally the whole of my interest in it.

Well, boy was I wrong about that. Glad I "naively" posted it and found out.
