This is definitely a skill. You can have, what seems to be, a bunch of jerks working together but they all have thick-skin so being a jerk to one another doesn't really affect any of them. Effectively hiring for this team is an exercise in finding people who think like they do.

Good meshing of personalities can override the predictions of the incompetent/niceness matrix in the article.
