Before Tit for Tat was worked out back in the very early 80s, there was no reliable way of modeling social behavior, ie communities over the long term. And quite frankly, social scientists were getting fairly depressed because it seemed that people were going to be pricks and that we were all doomed.

But in comparison to other solutions, Tit for Tat was an optimal, simple solution out of the Hobbesian representations of humanity towards Rousseau. Or at least Locke.

It's a logical representation of the problem of long-term interaction. Why do people cooperate as compared to screwing each other every chance they get.

Yeah. I've heard the Prisoners' Dilemma used to explain why there are so many asshole drivers in big cities. In a small town, it's like the multiple iteration of the Prisoners' Dilemma, so drivers that, say, regularly cut people off will soon find other drivers doing the same to them. But in a large city, a driver is essentially anonymous (in that other drivers will probably never see the driver again) so it's like the single iteration of the Prisoners Dilemma, so it makes sense (in a selfish way) to cut off other drivers so you can get ahead.

lisah, yep, and they know what the other decides.

Let me see...

Wiki: Conditions for Tit for Tat

1. Unless provoked, the agent/prisoner will always cooperate

2. If provoked, the agent/prisoner will retaliate

3. The agent/prisoner is quick to forgive

4. The agent/prisoner must have a good chance of competing against the opponent more than once.

A fifth condition applies to make the competition meaningful: if an agent knows that the next play will be the last, it should naturally defect for a higher score. Similarly if it knows that the next two plays will be the last, it should defect twice, and so on. Therefore the number of competitions must not be known in advance to the agents.

I did not know that.

ita! Our song just came on my playlist!

Whoa, that makes total sense. Except for the danger part.

PMM might know it, because it is not that far a shot from Evergreen.

Aww, man. Has it gone that far downhill? It didn't used to suck! That much, at least.

Or I was, you know, in college and had a cast-iron stomach or something.

what was the last movie you all saw? (people at work are having discussions, I want something else to focus on)
