I found this interesting video about an experiment that basically tests strategies for how to succeed in life. 

The options in the game are to:

1)Cooperate with your opponent, which earns both players a significant but equal increase in points (3points)

2)One player can "defect" or take advantage of the other to earn 5 points while the other gets 0 points

3)Both defect and both only earn 1 point.

It was found that "nice" strategies were the most successful, and had these qualities:
1)Nice (preferring to cooperate)
2) retaliatory/ not a pushover, just, tit for tat
3) forgiving
4) clear and trustworthy

One guy commented that the winning strategy did not resemble Christianity (turn the other cheek), but something older (old Testament eye for an eye law), but they went on to show that a limited addition of mercy and forgiveness further improved the results, which sounds to me like Catholicism, but of course they wouldn't mention that. 

It's a good watch

Well, the one thing that this does not model at all, with the typical scientific perspective that attempts to reduce everything to mathematical constructs and physics, etc., is a concept of "right or wrong".

But instead of "tit for tat," what if we apply "right or wrong" as our principle for decision making.  In that case, we're always on the side of good, and God decides the outcome.

There's the typical ethics "dilemma" that all non-Catholics struggle with.  If you could save a billion lives by murdering one individual, would you do it?  If you look at it from a crude mathematical perspective (such as game theory), you would certainly just do it.  And all non-Catholics wring their hands struggling with this.  But, as Catholics, we know that the end does not justify the means, and so we refuse to commit murder regardless of the consequences, and we leave the consequences up to God, who is in control of the "game".

But this game theory is all form the atheistic perspective.  God could just delete any program He wishes to, and unlike the "random" elements they inject into the games, God can deliberately inject anything He wants into any game at any time, could delete a game, etc.  God has complete control over the game.

Games change when rules are established from outside, extrinsic to the game, and there are referees in the game who enforce the rules, where the referee could even declare a winner on whatever terms He decides.  So, for instance, the "nice" one that didn't do so well, the "pushover" as it was called, what if God intervened and said at the end, "I declare 'pushover' the winner due to his niceness." and award the trophy and the prize to the so-called pushover on account of his sportsmanship and niceness.  That's reality, but game theory operates on the level of an atheistic construct where there are no rules and where there are no ultimate decision-makers or referees.  God's rules are that those who follow His rules are the ultimate winners.
