+The Golden Rule, reciprocal altruism, tit for tat, or... live and let live.

+Copycat doesn't just win the battle, it wins the war.
-Sorry, //////.
-
-Now, here's the strange thing: Copycat can _never_ beat another player in the trust game (because it never tries to take advantage of others), it can only ever do _as well as_ the other player. And yet overall, Copycat wins! This, despite being simpler than Detective, nicer than Always Cheat, and more forgiving than Grudger. It almost seems to imply that the Golden Rule is not just a moral truth, but a *mathematical* truth:
-
-*Do unto others as you would have them do unto you.* ~Copycat
-
-And *that's* why "peace" broke out in the trenches of World War I. Each side was playing a deadly game of trust with each other, but because the nature of trench warfare means they have to face the same group of soldiers over and over again, that allowed a Copycat-like strategy – the unspoken law of "live and let live" – to evolve.

+
+Say we start with the following population of players:
+15 Always Cooperates,
+5 Always Cheats, and
+5 Copycats.
+(We'll ignore Grudger & Detective for now)
+
+We're going to do the tournament-eliminate-reproduce dance a dozen times or so.
+Let's make another bet! Who do you think will win the first tournament?
+
+
+
+Makes sense, Always Cooperate outnumbers everyone else right now...
+
+
+Makes sense, Always Cheat has a lot of Always Cooperates to exploit...
+
+
+Makes sense, Copycat won the tournament last time, why not again?...
+
+
+Let's see if you're correct:
+
+
+
+1) play tournament
+
+
+2) eliminate bottom 5
+
+
+3) reproduce top 5
+
+
+
+Alas, Always Cooperate got eaten up by
+Always Cheat, whose numbers have now increased by 5.
+
+
+Sadly, you were correct! The Always Cheaters won this time,
+and their numbers increased by 5.
+
+
+Alas, Copycat did not win – but at least they didn't do as bad
+as Always Cooperate, who got eaten up by Always Cheat,
+whose numbers have now increased by 5.
+
+
+But let's try a few more rounds of this...
+
+
+
+Always Cheat is still growing,
+at the expense of Always Cooperate...
+
+
+
+And now, all the Always Cooperates are dead.
+But, wait...
+
+
+
+That's right: the Always Cheats became a victim of their own success!
+They exploited the naive Always Cooperaters,
+but once they ran out of them, they had to face the Copycats:
+who are nice, but not naive.
+
+
+
+
+
+
+By simply copying the other player's moves,
+Copycats can play nice with each other,
+while Always Cheats just cheat themselves.
+Not only that, but it also means Copycat
+can give Always Cheat
+a taste of their own medicine.
+
+
+
+And so, as a result...
+
+
+
+...Copycat inherits the earth.
+
+
+So, although your bet was off -- the nice-but-naive Always Cooperaters
+were doomed from the start -- in the end, a smart form of niceness prevailed,
+and the Always Cheaters were squashed.
+
+
+So, in the short run you were right - Always Cheat won the first few rounds,
+but in the end, its exploitativeness was its downfall.
+
+
+So, in the long run, you were right - Copycat wins!
+Always Cheat may have won in the short run,
+but its exploitativeness was its downfall.
+
+
+This reminds me of a quote:
+
+"We are punished by our sins, not for them."

+stop the evolution process
+
+
+
+
+
+
+(Note: occasionally, a few Grudgers may stick around,
+because when all players except Grudger & Copycat
+are eliminated, the two tie.)
+
+So, it seems the math of game theory is telling us something:
+that Copycat's philosophy,
+"Do unto others as you would have them do unto you", may be not just a
+moral truth, but also a mathematical truth.
+However...
+
+
+...there's a problem: →

+There are jerks. Look around.
+
+If Copycat is the strategy in this repeated game of trust that's so powerful --
+that even soldiers in the trenches of World War I independently "evolved" a similar strategy --
+why, then, are there so many un-trusting, un-trustworthy people around?
+
+A clue's in that sentence itself. "In this repeated game of trust."
