How good are arrogant individuals at their jobs?

Far from being the most able, arrogant workers were judged weaker in almost every way by one rating group or other. Some of the findings are less surprising: people who think their managers are arrogant grade them as poorer across the board, which may be influenced by a reverse halo effect (overgeneralising a negative feature) or using the rating process to punish those they resent. Some are more compelling: individuals who rate themselves more arrogant rate themselves weaker at relationships and overall performance, with their supervisors and direct reports agreeing.
