> But if you focus on the behaviour, you can try to negotiate: "You are a genius, your work on ___ is brilliant. However, this behaviour ____ is unacceptable, please stop doing it. Here is why..., Here is something more constructive you could consider..."

Incredibly well said - that's the point I was reaching towards and couldn't quite articulate perfectly, apparently. Ideally, we'd call out shitty behavior and change that behavior. I didn't mean to suggest a "my way or the highway" attitude; rather, my point is that we shouldn't keep quiet when someone's being a jerk.

Typically, I've managed to maintain a decent working relationship even with people others found virtually intolerable. My natural inclination is to let the more abrasive aspects of their personalities slide, but sometimes I doubt this approach, because occasionally what it means is taking them less seriously as human beings. Their idiosyncrasies can be predictable, so I'm tempted to think of them as machines. In one sense, it's convenient: I rarely get angry at machines, so why would I get angry at machine-like people? On the other hand, it's dismissive and lazy.

What you're talking about is rejecting cynicism, assuming things can change, believing things are worth changing, and being willing to put in the effort to call out the jerks. As long as you do it constructively, you end up humanizing people who probably need it--and you might even make a difference! So, for all our sakes, please keep it up.

Our words are in violent agreement. I wish more people would call my bad behaviour out.

Great and insightful comment! However, I think most "assholes" has an justification of their behavior that they find sufficient.

If the person thinks the greatness and contribution of their work is somehow dependent on the antisocial behavior, then it's hard to convinced them to separate behavior from action.

As a side-note I think this kind of asshole behavior is as prevalent in non-technical types as technical types.
