Why Kids Bully: Because They're Popular

Time Magazine

Mean kids, mothers tell their wounded young, behave that way because they have unhappy home lives, or feel inadequate, or don't have enough friends or because they somehow lack empathy. But a new study suggests some mean kids actually behave that way simply because they can.

Contrary to accepted ruffian-scholarship, the more popular a middle- or high-school kid becomes, the more central to the social network of the school, the more aggressive the behavior he or she engages in. At least, that was the case in North Carolina, where students from 19 middle and high schools were studied for 4.5 years by researchers at the University of California-Davis.
