  • Mô tả: •Few studies have considered private assessment due to analytical difficulty.•We develop an analytical method using solitary observation to solve it.•Private assessment provides a different result to public assessment.•Without central coercive system, private assessment reaches high cooperation rate.•Our results also show the three advantages of the staying norm in private assessment. Although indirect reciprocity is a fundamental mechanism in the evolution of human cooperation, most studies assume public assessment in which individuals are not permitted to obtain private assessments of others. Existing studies on private assessment have used individual-based simulations because of the analytical difficulty involved. Here, we develop an analytical method using solitary observation to solve private assessment in indirect reciprocity problem without any approximation. In this study, we formulate a model of solitary observation and calculate the replicator dynamics...
