Maybe you're a collaborative person so you get put on teams where that's more highly weighted. I'm more of a "don't talk to me / I hate meetings" developer; I get excellent evaluations, but I almost always work independently and the groups I work with quickly pick up on my temperament.

I will say that I'm certain I'd be shown the door if I didn't have a track record of going off into the Batcave for a few months and coming back with cool products.
