Why Men Give Bad Advice to Other Men

I think women are particularly good at this if they're chasing a high status guy. And I don't know, plausible deniability. The other thing I want to cover too, it's not just women. This is not like women just fool themselves and men are these rational beings who understand everything. Even if it's obviously not on purpose. So what are some of the reasons or like the sort of situations that happen where men give bad advice to other men?
