I’d note that I expect these clusters (and I suspect they’re clusters) to be a minority of intellectuals. They stand out a fair bit to me, but they’re unusual. I agree Bryan Caplan leans disagreeable, but is less intense than others. I found The Case Against Education and some of his other work purposefully edgy, which is disagreeable-type-stuff, but at the same time, I found his interviews to often be more reasonable. I would definitely see the “disagreeable” and “assessor” archetypes as a spectrum, and also think one person can have the perks of both.
