Observational learning theories often assume that people’s actions can be observed. However, in many naturally-occurring environments, individuals choose whether to disclose their behavior others. We provide theoretical analysis of observational under optional disclosure conditions. further examine empirically how decide reveal decisions. Although we find evidence for other-regarding behavior...
