So says CNN. The Magistra sent me this today. Apparently she's trying to tell me something. I'm not really surprised at the results. The article focuses on social interactions, but I think the real effect likely comes not from being a jerk per se, but the willingness and ability to take risks, to provide critical feedback, and the ability to ignore naysayers. Being a jerk is just a side effect of the personality traits that enable these other things.
Steve Hsu had a post that touched on this. Look at Figure 7. The one we are interested in is A, agreeableness.
