I gave him a try. He does a decent job breaking personalities down without over-simplification or losing people in the details.
But I will say he does strike me obviously as a sort of "trust the facts" type.
Like one video he's critiquing Narcissist channels on Youtube and saying how he doesn't like that people have grown to hate narcissists and their emboldening by these videos and that in his experience narcissists can change, and of course bringing up that he's got a PhD several times.
That's cool for him but from personal experience, that moral absolutism definitely has helped me personally with narcissists way more than regarding them as "the psychological field" would.
I'm not saying he's not informed. But I think he definitely has that sense of superior a lot of people in his field have.
