Arrogance v agreeableness
"If I can choose between an arrogant rocket scientist and an agreeable guy that I love to work with - that isn't quite as talented yet, I choose the latter."
So, discrimination against people with e.g. Asperger's Syndrome, huh?
I have a bit of a game I like to play with people. I ask them whether they would rather deal with someone who is lacking in interpersonal skills, but who gets the job done properly, on time, every time, or someone who has all the interpersonal skills going, but fails the "getting the job done" test say, 25% of the time. The answer tells me a lot about the person, and it worries me that so many people would prefer the inefficient but pleasant person over the grumpy but efficient one, especially in roles where "niceness" is completely irrelevant - e.g. someone to fix the car.
