NYTimes: In defense of teasing
Given the perils of negotiating rank, many species have evolved dramatized status contests, relying on symbolic displays of physical size and force to peacefully sort out who’s on top. Stags roar. Frogs croak. Chimps throw branches around. Hippos open their jaws as wide as possible to impress competitors.
And humans tease. Teasing can be thought of as a status contest with a twist. As humans evolved the ability to form complex alliances, the power of a single individual came increasingly to depend on the ability to build strong bonds. Power became a matter of social intelligence (the good of the group) rather than of survival of the fittest (raw strength). As a status contest, teasing must walk a fine line, designating status while enhancing social connection.
