You have revised my thinking a bit. I think those that are most advanced (from an evolutionary perspective) are those who can convince others of a strict moral code while at the same time convincing them that because of their personal position, heritage, etc. they are somehow exempt from this morality, and any violations of that they must commit of that strict moral code is for the greater good, national security, etc.
Hmmm. It's an interesting hypothesis, but I would say this could also have as much to do about humanity's apparent instinctual response to accept authority, which I have made the assertion that this very well could also be an evolved behavior/instinct, as a lot of human "growth" has resulted form the centralization of leadership and the specialization of tasks within a population.
Such people have the best chance of passing on their ideas and genes. It seems to me that all the rest of this is nothing more than a lot of yada...yada.
I would also point out though, that societies where this happens is often doomed to mass "unhappiness", revolution, restructuring, recentralization, mass "unhappiness", revolution, restructuring, recentralization....
ad infinitum. While it's very true that the "genetic success" of the few do indeed happen in this particular time, this comes as the cost of "genetic success" of a larger group of people in the population, something that Rillion points out eventaully get "punished," since in essence this can be a kind of "social cheating." Who knows though, I'm not an anthropologist nor psychologist by education.
While I can see the arguments made, I think one of the problems we have is that there is no long-term verifiable "test cases" where we can see, measure and observe a society of a group of individuals that collectively share this "proper morality," and therefore cannot draw any real conclusions based on actual observable evidence. As this thread illustrates, we're dealing mostly in the academic abstracts of hypothesis, hypotheticals and conjecture.
(EDIT: changed "humanities" to the proper "humanity's")
