Like picking your nose or re-using a dirty coffee cup, trading petty observations and suspicions about others is a function of life no one takes any particular pride in. You might have been told by parents not to say anything about someone "behind their back," and gossip often involves some degree of schadenfreude. In terms of keeping a positive outlook, there's not much to be said for chattering about whether someone got a facelift or if a divorce might be imminent.
Or is there? Ben Healy of The Atlantic recently aggregated compelling data that points to gossip having surprising benefits. When two people discuss negative feelings about a third, they tend to bond over the shared hostility more than if they were sharing pleasant thoughts about him or her. The badmouthing parties also tend to enjoy a sense of accomplishment by reflecting on their own positive traits compared to the failure of others. They might even take a "lesson" from an anecdote about someone's catastrophic life, using it as a cautionary tale. If the gossip has a positive slant, it might be used as inspiration to pursue self-improvement.
That's the other surprising thing about gossip: 96 percent of the time or more, it's not overly negative. Among adolescents, it's usually used to vent about frustrations or to create conversation in pursuit of a bonding experience.
If gossip truly is good for the soul, most of us are in luck. Talking about an absentee third person is what accounts for two-thirds of all conversation.
