Supermarket dating

If one stays quiet while the other confesses, then the snitch will get to go free, while the one who stayed quiet will face a whole year in jail.

And if both hold their tongue, then they each face a minor charge, and only a month in jail.

But given knowledge that the other player’s best decision is to “confess and betray,” each prisoner individually chooses to confess, ending up with both going to prison for three months each. Suppose 20 men and 20 women show up at the supermarket, it’s pretty clear that all the men and women will pair up and split the 0 gain about equally: :.Now imagine that the sex ratio changes to 19 men and 20 women.You would imagine that this would only have a minor effect on proceedings but then you’d be surprised.Dating apps have become more like slot machines, where the promise of an occasional match keeps us swiping incessantly.This is called variable ratio reinforcement: The prize is unpredictable, but it’s out there, which keeps us coming back for more.This skewed ratio would translate into men trying that extra bit hard to get female attention on dating services and when extra hard in the Tinder generation means just another right swipe, this imbalance leads to men swiping right on as many female profiles as they possibly can.
