All of you will participate in 4 independent rounds of decision-making within the group. At the start of the first three rounds, a computer will randomly assign you to a new position within your 4-member group: “position 1”, “position 2”, “position 3”, or “position 4”. You will be in each position only once, so will each member of your group.
The “Red” urn contains 2 red balls and 1 blue ball:
The “Blue” urn contains 2 blue balls and 1 red ball:
At the beginning of each round, a computer will randomly select one of these urns with an equal 50% probability. Neither you nor other members of your group are informed as to which urn is selected for the round. The selected urn will be the same urn for all members of your 4-member group for that particular round.
We will call this selected urn the “group urn”.
Each of your group members, including you, will make her/his group urn guess one after the other, according to her/his position in sequence within the group in each round.
For example, if you are in position 2, you are the second person guessing the group urn in that round. Two other members of your group, assigned to position 3 and position 4, will guess after you. The member in position 1 will guess before you.
