Nice Guys Finish First (BBC Horizon television series) is a 1986 documentary by Richard Dawkins which discusses selfishness and cooperation, arguing that evolution often favors co-operative behaviour, and focusing especially on the tit for tat strategy of the prisoner's dilemma game. The twelfth chapter in Dawkins' book The Selfish Gene (added in the second edition, 1989) is also named Nice Guys Finish First and explores similar material.
