Gossip

Gossip is important. According to PSYCH101.

Gossip may sound trivial and seem to belittle our noble ability for language—surely one of the most remarkable human abilities of all that distinguish us from other animals. Au contraire, some have argued that gossip—activities to think and communicate about our social world—is one of the most critical uses to which language has been put.

Dunbar (1996) conjectured that gossiping is the human equivalent of grooming, monkeys and primates attending and tending to each other by cleaning each other’s fur. He argues that it is an act of socializing, signaling the importance of one’s partner.

Furthermore, by gossiping, humans can communicate and share their representations about their social world—who their friends and enemies are, what the right thing to do is under what circumstances, and so on. In so doing, they can regulate their social world—making more friends and enlarging one’s own group (often called the ingroup, the group to which one belongs) against other groups (outgroups) that are more likely to be one’s enemies. Dunbar has argued that it is these social effects that have given humans an evolutionary advantage and larger brains, which, in turn, help humans to think more complex and abstract thoughts and, more important, maintain larger ingroups. Dunbar (1993) estimated an equation that predicts average group size of nonhuman primate genera from their average neocortex size (the part of the brain that supports higher order cognition). In line with his social brain hypothesis, Dunbar showed that those primate genera that have larger brains tend to live in larger groups. Furthermore, using the same equation, he was able to estimate the group size that human brains can support, which turned out to be about 150—approximately the size of modern hunter-gatherer communities. Dunbar’s argument is that language, brain, and human group living have co-evolved—language and human sociality are inseparable.
