Welcome to this experiment. In the next 5-10 minutes you will be playing a so-called Guessing game. This game, rooted in game theory, challenges you to think strategically and make predictions about others players' decisions.

Game Instructions

You will be playing this game for one round in a group of four. Each participant is asked to guess a number between 0 and 100. The winner is the person whose chosen number is closest to the mean of all chosen numbers multiplied by a parameter p. In this case, the parameter p is set to 2/3.

Once everyone submits their guesses, the average of all the guesses will be calculated and multiplied by 2/3. The participant whose guess is closest to this calculated value will be the winner.

Please, note again that you will be playing this game for one round only and you will not be aware of the other players' decision when making your own decision.

You will be able to see the game instructions again when making your final decision.
