In 1998, Keltner and his team had small groups of three volunteers come into their lab. One was randomly assigned to be the group leader and they were all given a dull task to complete. Presently, an assistant brought in a plate containing five cookies for the group to share. All groups left one cookie on the plate (a golden rule of etiquette), but in almost every case the fourth cookie was scarfed down by the leader. What’s more, one of Keltner’s doctoral students noticed that the leaders also seemed to be messier eaters. Replaying the videos, it became clear that these ‘cookie monsters’ more often ate with their mouths open, ate more noisily and sprayed more crumbs on their shirts. Maybe this sounds like your boss?
