This is interesting. I just finished listening to an old episode of This American Life about this same subject.

http://www.thisamericanlife.org/radio-archives/episode/370/r... (it's the prologue if you want to listen)

the story was about an experiment that was done to test the effects of these same three personality types on a working environment (although they called the flake the slacker, and the heretic was a bit different ,as the depressive)

To do this they repeatedly inserted an actor who would display one of these behaviors into a working group and study the outcome - and groups with any kind of disruptive co worker ended up doing considerably worse on their projects. Also interesting, the other members of the group took on the traits of the actor... When he was acting a jerk, the others in the group became rude not only to the jerk but to each other. When he was the slacker, everyone else started slacking more also. And when he was the depressive everyone else became more depressed.

The only time the actor did not effect the groups performance was in one team where a particularly charismatic member was able to diffuse all situations where he was being a jerk.
