Groups that allow their members to gossip sustain cooperation and deter selfishness better than those that don't. And groups do even better if they can gossip and ostracize untrustworthy members. While both of these behaviors can be misused, our findings suggest that they also serve very important functions for groups and society.Of course, trash-talking people out of spite or to simply pick a fight won't do much to help morale. But talking with your coworkers or bosses about problems in the workplace not only helps keep the lines of communication open, but strengthens the bond between other members of the group.
