This is a video about the most famous problem in game theory.
Problems of this sort pop up everywhere, from nations locked in conflict to roommates doing the dishes.
Even game shows have been based around this concept.
Figuring out the best strategy can mean the difference between life and death, war and peace,
flourishing and the destruction of the planet.
And in the mechanics of this game, we may find the very source of one of the most unexpected phenomena in nature.
co-operation.
On the 3rd of September 1949, an American weather monitoring plane collected air samples
over Japan.
In those samples, they found traces of radioactive material.
The Navy quickly collected and tested rainwater samples from their ships and bases all over
the world.
They also detected small amounts of Serium 141 and Itrium 91.
But these isotopes have half-lives of one or two months, so they must have been produced
recently.
And the only place they could have come from was a nuclear explosion.
But the US hadn't performed any tests that year, so the only possible conclusion was that
the Soviet Union had figured out how to make a nuclear bomb.
This was the news the Americans had been dreading.
Their military supremacy, achieved through the Manhattan Project, was quickly fading.
This makes the problem of Western Europe and the United States far more serious than
it was before, and perhaps makes the eminence of war greater.
Some thought their best course of action was to launch an unprovoked nuclear strike against
the Soviets while they were still ahead.
In the words of Navy Secretary Matthews, to become aggressors for peace.
John von Neumann, the founder of Game Theory, said,
If you say, why not bomb them tomorrow?
I say, why not bomb them today?
If you say, today at 5 o'clock?
I say, why not at 1 o'clock?
Something needed to be done about nuclear weapons and fast.
But what?
In 1950, the Rand Corporation, a US-based think tank,
was studying this question.
And as part of this research, they turned to Game Theory.
That same year, two mathematicians at Rand had invented a new game, one which, unbeknownst
to them at the time, closely resembled the US Soviet conflict.
This game is now known as the Prisoner's Dilemma, so let's play a game.
A banker with a chest full of gold coins invites you and another player to play against
each other.
You each get two choices.
You can cooperate or you can defect.
If you both cooperate, you each get three coins.
If one of you cooperates but the other defects, then the one who defected gets five coins
and the other gets nothing.
And if you both defect, then you each get a coin.
The goal of the game is simple to get as many coins as you can.
So what would you do?
Suppose your opponent cooperates, then you could also cooperate and get three coins.
or you could defect and get five coins instead. So you are better off defecting.
