Almost everthing I’m about to say is completely peripheral to the original topic. If we’re going to keep discussing it, should we start a new thread?
Thank you so much for that link on game theory, Sage Rat. (Love game theory, btw.) [http://findarticles.com/p/articles/mi_m1200/is_4_166/ai_n6151880](game theory link)
but it refutes your assertion.
“Maynard Smith and the late George Price showed that cooperators and defectors coexist stably in a mix whose proportions are determined by the payoffs of the particular game.”
Not only does the article suggest, as cosmosdan also did, that populations can change over time, but also that if you set up the payoffs properly, you can change the proportions to what you want, (say… to have more cooperators.)
concerning the prisoner’s dilemma game…
“Chase through the options, and you’ll find that no matter what course one prisoner chooses, the other will do better by defecting.”
I’ve said often, (elsewhere,) that an individuals best result is when everyone else follows the rules, but he is free to do whatever he wants. Or as the article called it, he cheats.
I’ve said this before as well… Democracy and Capitalism are the best systems we’ve come up with to deal with humans as they exist. (although we’ve seen some recent hiccups in unfettered capitalism lately, haven’t we?)
But, why be content there with humans as they are? Why can’t we cooperators set up the payoffs to increase the proportion of cooperators? The defectors have always tried to change the rules, and those have often been the cause of the hiccups, (Enron, Worldcom, the sub-prime mortgage crisis we’ve seen most recently were all caused by defectors lobbying to change the rules so they could make boatloads of money.)
Sage Rat’s article has suggested to me that, not only can we change ourselves, and encourage others to change, we can set up the game to encourage cooperation. Animals evolve to cooperate even in situations where logic says the best *individual *outcome is to defect because the optimal survival option is cooperation. So, cooperators survived.
Also from the article-
“Whenever nature achieves a major step, it involves cooperation,”
But, if the best individual outcome, (logically,) is defection:
You could surmise from that, that logic has been our downfall. hmmm.
(Or, you could conclude that the best individual outcome is not the one we should be striving for, but the best collective outcome. hmmm, change the attitute of the individuals to think about the group. Why didn’t anyone think of … Oh, wait, that’s what cosmosdan and I suggested.)
Oh, and back on topic, I liked JohnT’s point that it doesn’t matter if “someone else would have invented it.” only what caused the greatest effect. (I still nominate the invention of zero. Math and science and almost every advance in the last 1500 years hinge on it.)
