Description: Data and analysis code for: Gaechter, Molleman and Nosenzo: "Why people follow rules". Under revision at Nature Human Behaviour ABSTRACT. Why people follow rules, especially laws and social norms, is debated across the human sciences. The importance of intrinsic respect for rules is particularly controversial. To reveal the behavioural principles of rule-following, we develop CRISP, an interdisciplinary experimental framework that explains rule-conformity as a function of intrinsic respect for rules, extrinsic incentives, social expectations, and social preferences. In our baseline experiments, 55-70% of people, acting anonymously and alone, obey an arbitrary rule, even though a violation implies a net gain and hurts no-one. We show that people expect rule-conformity and view it as socially appropriate. Rule-breaking is contagious but never exceeds 60%. Pro-social motives and extrinsic incentives increase rule-conformity, but unconditional rule-following and social expectations explain most of it. Our results demonstrate that respect for rules, and social expectations, are basic elements of rule-conformity that can explain why people follow laws and social norms even without extrinsic incentives.
