Laughter is social bonding communication. It’s like saying, “I like you” or “I want you to like me.” Evolutionary psychologist Robin Dunbar says that belly laughing may have worked like “grooming at a distance” for early ancestors, allowing them to maintain bonds within larger groups, which explains why humor in ads can bond people to brands. Laughter is an innate, cross-cultural response triggered unconsciously, which is why it is hard to fake or control. Shared laughter synchronizes our brains in emotional attunement, the hallmark of successful communication, releasing oxytocin and tension, firing our trust circuits.
