Nice Guys Finish First is a 1986 documentary by Richard Dawkins which discusses selfishness and cooperation, arguing that evolution often favors co-operative behavior, and focusing especially on the tit for tat strategy of the prisoner's dilemma game.
In the opening scene, Richard Dawkins responds very precisely to what he views as a misrepresentation of his first book The Selfish Gene. In particular the response of the right wing for using it as justification for social Darwinism and laissez-faire economics (free-market capitalism).
Richard Dawkins has examined this issue throughout his whole career and focused much of the recent documentary, The Genius of Charles Darwin on this very issue.
The concept of reciprocal altruism is a central theme of this documentary. Dawkins also examines the tragedy of the commons and the dilemma that it presents. He uses the large area of common land Port Meadow in Oxford, England which has been hurt by overgrazing as an example of the tragedy of the commons.
Fourteen academics as well as experts in game theory submitted their own computer programs to compete in a tournament to see who would win in the prisoner's dilemma. The winner was tit for tat. A program which is based on "equal retaliation" and Dawkins illustrates the four conditions of tit for tat.
In a second trial, this time of over sixty applicants tit for tat won again.
The documentary does not seem to address much larger issues within the tragedy of the commons for example it only briefly mentions global warming. Yet "Initial niceness" is a conclusion that Richard Dawkins drew from this study and other research for effective cooperation which led him to believe that in fact, "Nice guys finish first."
