Bosses who are in over their heads are more likely to bully subordinates. That's because feelings of inadequacy trigger them to lash out at those around them, according to new research from the University of California, Berkeley, and the University of Southern California. In a new twist on the adage "power corrupts," researchers at UC Berkeley and USC have found a direct link among supervisors and upper management between self-perceived incompetence and aggression. The findings, gleaned from four separate studies, are published in the November issue of the journal Psychological Science. With more than one-third of American workers reporting that their bosses have sabotaged, yelled at or belittled them, the new study challenges previous assumptions that abusive bosses are solely driven by ambition and the need to hold onto their power. "By showing when and why power leads to aggression, these findings are highly relevant as abusive supervision is such a pervasive problem in society," said Nathanael Fast, assistant professor of management and organization at USC and lead author of the study. During role-playing sessions, study participants who felt their egos were under threat would go so far as to needlessly sabotage an underling's chances of winning money. In another test, participants who felt inadequate would request that a subordinate who gave a wrong answer to a test be notified by a loud obnoxious horn, even though they had the option of choosing silence or a quiet sound.
