In case you were wondering, this phrase came has been attributed to baseball manager Leo Durocher in 1939. And although this phrase was coined in baseball, as we know it has other contexts too.
There has been research done on this. It was also coined by American biologist Garrett Hardin. He discussed a concept called “selfish gene” which was later disputed by Richard Dawkins. There was a BBC documentary Nice Guys Finish First.
As much as there is science to discuss this, we all have some personal experience and reflections of this. So, I ask you, is this true?
