Working in harmony with others, science shows, makes it more likely we’ll do good. For instance, research by Bahar Tunçgenç and Emma Cohen of the University of Oxford has found that children who played a rhythmic, synchronized clap-and-tap game were more likely than children who played nonsynchronous games to later help their peers.31 In similar experiments, children who first played synchronous games were far more likely than others to say that if they were to come back for more activities they would be interested in playing with a child who wasn’t in their original group.
