Two groups of people are asked to participate in a multi-round investment game. In each round, every participant is given $10 and can secretly contribute any amount to a group project. The total amount contributed by the group is then doubled and distributed equally among all participants, regardless of their individual contributions.

In Group A, participants can only see the total contribution to the project after each round.

In Group B, participants are shown each individual's contribution after each round and are given the option to spend $1 of their own earnings to reduce another participant's earnings for that round by $3.

Based on experimental findings, which outcome is most likely over the course of many rounds?
