Wiley,
That graphic is like the psych tests run with a panel of college kids at two different colleges. Each kid was given an equal number of tokens to represent money at one school, the ability to effect others grades at another school while observing anonymously. The token representing the money experiment, each kid was given the option to reward others for their part in a team effort with 5 teams that was observed by the panel of kids with the tokens. They could give 0%, 1%, 5%, 10%, 25%, or 50% of their token bank account value to individuals or the observed team.
The same kind of test was run at the other college but the observing kids gave demerits against a final grade for each student involved in the activity teams. Or a total team grade. Similar break down, 0, 1, 5......and so forth.
Girls were very charitable giving as a majority 10% tokens to each of the collective teams and not dinging team grades by much more than 10%. The guys on the other hand were very stingy and graded harshly. The majority of guys wanted to keep their bank tokens and enjoyed slamming the teams grades mostly because they could. There were no rules against keeping all of the tokens or even failing the teams. On average the guys gave 1% to 5% in tokens to each Team or dinged the Team grade down to a C-D grade level.
Yes I can see voting to enhance another player's status in this game.....
