The Culture Code: The Secrets of Highly Successful Groups

by Daniel Coyle

subjects were asked to help a fictitious student named “Eric” write a cover letter for a job application. After helping him, half of the participants received a thankful response from Eric; half received a neutral response. The subjects then received a request for help from “Steve,” a different student. Those who had received thanks from Eric chose to help Steve more than twice as often as those who had received the neutral response. In other words, a small thank-you caused people to behave far more generously to a completely different person. This is because thank-yous aren’t only expressions of gratitude; they’re crucial belonging cues that generate a contagious sense of safety, connection, and motivation.
