Game theory of dating
Each prisoner must choose to betray the other or to remain silent.
Each one is assured that the other would not know about the betrayal before the end of the investigation. As you look at this, it is obvious that the best course of action is for the prisoners to cooperate so that they each get 6 months.
(The same goes for boys of course, but as we will see, the girl case is easier to comprehend). As a good-looking girl with many admirers, your job is to end up with the best suitor you can, in other words to sort the wheat from the chaff.
Getting a partner isn’t a problem; getting the right one is.
If each betrays the other, each receives a five-year sentence.To get there, you have to eventually decide to be nice. After all, no one is perfect, you hold all the cards, so why not wait for the real Prince Charming? If you live in an urban environment, where you come into contact with many people and a lot of potential suitors, you’d be more likely to hold out for the jackpot.Also, playing the mean strategy might become a force of habit.Your strategy should thus be to increase your desirability with clothes, grooming and whatever accoutrements you can muster, and decrease your availability (“Sorry, I have to stay in to wash my hair”).
This is, of course, the stuff of myth and fairy tale, wherein the Prince or suitor has to slay dragons, cut through thorns and perform countless other disagreeable tasks in order to win the Princess, whose only real obligation is to be beautiful.Thirdly, as we have seen above, it’s a non-losing strategy.
