How Reasoning About Errors can Affect Indirect Reciprocity
- Bryce Morsky, FSU
Time: 3:05 Room: 232 Love
Abstract/Desc: Indirect reciprocity serves as a pivotal mechanism in fostering cooperative behaviour within social groups. However, challenges arise in maintaining its effectiveness due to errors in assessments and actions, leading to disagreements on reputations and an unravelling of cooperation. To address these challenges, we explore two cognitive mechanisms, Bayesian and abductive reasoning. By considering the probabilities of errors along with prior beliefs about the prevalence of good and bad individuals, observers employ reasoning to aide in evaluating the reputations of others. Under Bayesian reasoning, this is an application of Bayes' rule. While under abductive reasoning, individuals' beliefs and observations are combined to infer reputations. Further, abductive reasoning is in a sense "lazy" since it only considers the simplest explanations when accounting for errors. We assess the effectiveness of such reasoning on promoting cooperation under various conditions. We find that Bayesian reasoning generallyundermines cooperation relative to the non-reasoning and abductive reasoning models, expect for the Scoring norm. Abductive reasoning generally outperforms the non-reasoning and Bayesian reasoning models but may undermine cooperation in high-error situations. Further, we find that a slight pessimism about the reputations of others or a resistance to changing reputations can benefit cooperation.
