In fact, there are two pure Nash Equilibrium in this game, where Nash goes for the blonde and his friend goes for a brunette, and where Nash goes for a brunette and his friend goes for the blonde. So, this scene does not use Nash Equilibrium in analyzing the game at hand but rather brings up one of the possible flaws of using game theory in real applications: if the players have time to communicate with each other and are friends , they can try to maximize the payoff for each player, rather than go for what is individually best for them.
But there are other situations where game theory in the real world fails as well. For example, the New York Times had their readers participate in an interesting game, which can be seen here. Each reader is asked to pick a number between 0 and that represents their guess as to what two-thirds of the average guess will be rounded to the nearest whole number, presumably. The average of the three guesses is 3, and two-thirds of that is 2. So the player who picked 2 would win.
It is not quite as simple as the two-player games that we have been studying in class since there are actually approximately 59, other players, each trying to choose the optimal strategy. It assumes that the other players are just choosing randomly when, in fact, they are also thinking what the optimal strategy would be. So, if everyone thought the same thing as you, then they will all try to pick So, if you pick two-thirds of 33 which is 22 , then would this be the optimal strategy?
Again, you have to take into account that the other players are thinking like you are. Select personalised content. Create a personalised content profile. Measure ad performance.
