Welcome to the third and last game! Please familiarize yourself with the illustration below. For this experiment, you are randomly paired with another participant, who CAN influence the payouts.

You find yourself on the top at point "P". You are going to decide whether to play "A" or "B". The first number in each bracket indicates your payout and the second number reflects the payout of the other participant. A is the safe option, where you can get 10 euros without any risk. The participant assigned to you is going to get 10 euros as well. If you choose B, point "N" is reached and this time it isn't a random process that decides the payouts. It is actually the other participant, who can decide whether to choose 1 or 2. If you choose B, one randomly selected person out of a group of 100 people is going to decide whether to play cooperatively (choose 1) or not (choose 2). He decides over the final payouts: Either 15 for him and 15 for you, or 22 for him and 8 for you.

There are statistics on the last 100 of these games played, that contain the fraction of the 100 trustees (participants who have been trusted because "B" was chosen from the trustor (Player 1)) that played cooperatively after the trustor chose B.

If one of exactly these 100 people is going to be assigned to you, what is the minimum fraction so that you would be willing to choose B?

For comprehension: If the statistics say that out of the 100 trustees only one played cooperatively, the chance that your randomly selected player is going to cooperate is very low. You would probably rather choose A. In contrast, if out of the 100 trustees 99 played cooperatively, the chance that your randomly selected player 2 is going to cooperate and you get the higher payout is very high. You would probably choose B. So the rate/percentage you choose, should be somewhere in between.

Please indicate your decision in the box below by typing a number between 0 and 1.
