I was always the best athlete, people don't know that. But I was successful at everything I ever did and then I run for president, first time - first time, not three times, not six times. I ran for President first time and lo and behold, I win. And then people say oh, is he a smart person? I'm smarter than all of them put together, but they can't admit it. They had a bad year.
Individual versus group selection results in a mix of altruism and selfishness, of virtue and sin, among the members of a society. If one colony member devotes its life to service over marriage, the individual is of benefit to the society, even though it does not have personal offspring. A soldier going into battle will benefit his country, but he runs a higher risk of death than one who does not. An altruist benefits the group, but a layabout or coward who saves his own energy and reduces his bodily risk passes the resulting social cost to others.
