The Nash equilibrium of the p-Beauty contest.
In 1981, Ledoux used this game as a tie breaker in his French magazine.
Individuals in the second group were generally able to disregard their own preferences and accurately make a decision based on the expected preferences of others.Retrieved Includes a histogram of the guesses.For instance in the p -beauty contest game (Moulin 1986 all participants are day runner promotion code asked to simultaneously pick a number between 0 and 100.The listeners were broken into two groups.These Level 1 players therefore reason that the average of all numbers submitted should be around.In game theory, " guess 2/3 of the average " is a game where several people guess what 2/3 of the average of their guesses will be, and where the numbers are restricted to the real numbers between 0 and 100, inclusive.Nagel found that people based their guesses on levels of rationality and found lumps of guesses on: level 0 rationality (guessing 50 level 1 rationality, best response to 50 (guessing 33 level 2 rationality, best response to 33 (guessing 22 etc.This equilibrium can be found by iterated elimination of weakly dominated strategies.In another variation of reasoning towards the beauty contest, the players may begin to judge contestants based on the most distinguishable unique property found scarcely clustered in the group.For instance, pick a student who guessed 33 and ask them why.After collecting responses, show the results, explain them, and rerun.

Similarly, the next higher 'Level 3' players play a best response to the play of Level 2 players and.
