bet365 sports newspaper’s comprehensive foreign media reports According to the official website of the University of Pennsylvania on June 11，Joshua B, professor of the Department of Biology of the school. Plotkin (Joshua B. Plotkin et al.’s new paper "Compliance with Public Institutions Aimed at Promoting Cooperation"，Use mathematical models to study how to establish a bet365 sports agency，To promote cooperation among members of society。

People have the spirit of cooperation，But there are many studies showing that cooperation is conditional: people are more likely to cooperate with people they think are "good"。According to indirect reciprocity theory，Even if no actual benefit will be obtained，People also tend to work with someone who has a good reputation，Because it can increase social capital、Improve your reputation。But，When there are many members in society，It is difficult for people to know the reputation of the people they interact with。And，People’s judgments of other people’s reputations are personalized，It is impossible to achieve cooperation when we have different opinions。The bet365 sports system was born，For example, the seller star rating of the e-commerce platform、Credit rating agency score，Help people decide if they can deal with another person。

This new study proposes the establishment of a bet365 sports agency to promote cooperation，And used mathematical models to test what core characteristics such institutions should have，And the circumstances under which people follow agency assessments。Researchers designed a scenario，Individuals can choose to make decisions based on their own judgment of the reputation of others or based on a public agency's assessment of the reputation of others。Researchers found，By adjusting the size of bet365 sports bodies and the rigor of assessments，The highest degree of cooperation can be achieved，The optimal values ​​of size and stringency depend on the dominant social norms。And，People’s compliance with public institutions spreads through social contagion，Even if only a few initially comply with the public agency’s assessment。

Then，If people had to pay taxes to support a bet365 sports system，What will happen？Can such institutions avoid corruption or bias？What if there are multiple social norms in the total population？Plotkin et al. hope to examine these issues in future research，In order to better apply research results to human society。
