Aside: Jordan Peterson bases his advice on heavily-validated psychological research, which if followed, would place men half in and half out of the Man Box.

For example, he's off the charts on self-sufficiency, but completely against hypersexuality, in everything I've seen from him. (Which isn't very much, to be fair.)

It might not be good for society as a whole, and it might be impractical if the mindset doesn't lend itself to half-in-half-out (the studies he bases his advice on are mostly correlational, not interventionist, from what I've seen), and he's apparently fallen victim to popularity psychosis, where if people love what you say about one thing (because it has a lot of truth, because you know what you're talking about), you think that you're right about everything (which you aren't) and also view an enthusiastic response as further indication of correctness (which obviously it isn't, necessarily).

But if he's wrong in his advice to men about how to have a satisfying and productive life, he's wrong for complex reasons. Unlike Tate, for instance, who is quite straightforwardly bad.
