This is my experience - they are very often people who are so highly specialised in one thing that they lose the ability to talk to other people. Their egos are inflated (as no-one else understands them) they go around causing havoc.
I tended towards this but was - I guess - lucky to have had a manager who identified this and helped me grow.
My approach: the young ones need to fail. Hard. Then they'll learn.
The older ones who failed and reacted badly (it was everyone else's fault). I take them out of their comfort zone, tell them about my experiences and talk about the feeling of self-doubt when moving to different domains. Work with them to turn them into truly excellent team members (which they - in my experience - can be as they're usually driven, hard working and egotistical).
