The Selfish Gene
Simplistically, the term "nice guy" could be an adjectival phrase describing what appears to be a friendly, kind, or courteous man. The "nice guys finish last" phrase is also said to be coined by American biologist Garrett Hardin to sum up the selfish gene theory of life and evolution. This was disputed by Richard Dawkins, who wrote the book "The Selfish Gene". Dawkins was misinterpreted by many as confirming the "nice guy finishing last" view, but refuted the claims in the BBC documentary "Nice Guys Finish First".
