This 2015 Cambridge/Oxford study found:

“Global reputational knowledge is crucial to sustaining a high level of cooperation and welfare.”

Basically, the subjects learned how to “game” a cooperative online game, and the researchers drew up their findings.

To me, the study demonstrated part of the findings of the Reciprocity behaviors differ as to whether we seek cerebral vs. limbic system rewards study, the part where the cerebrum was active in:

“Reputation-based reciprocity, in which they help others with good reputations to gain good reputations themselves.”

The current study ignored how people’s limbic system and lower brain areas may have motivated them to cooperate.

I didn’t see how excluding people’s emotional involvement when cooperating with others improved the potential reach of this study’s findings. Doesn’t a person’s willingness to cooperate in person and in online activities usually also include their emotional motivations?

The findings can’t be applied generally to cooperative motivations and behaviors that the researchers intentionally left out of the study. The study’s findings applied just to the artificial environment of their experiment, and didn’t provide evidence for how:

“Cooperative behavior is fundamental for a society to thrive.”
