Well, I know I won't get any votes. My bias and dogma (assuming you mean beliefs and ideology) not only cloud my judgement, they dominate it.
I know what I wrote was vague, but I what guess I meant by "bias and dogma" is an inability to even consider the softening of one's position in light of new evidence or arguement. Not many here are that bad, though I know I've been guilty of it before.

And I hope no one is offended by not being mentioned. I do think most of us are fair to some degree or another.
