Society changes, but the degree to which it has changed can be difficult to evaluate. We propose that people possess beliefs that society has made, and will make, progress in a linear fashion toward social justice. Five sets of studies (13 studies in total) demonstrate that American participants consistently estimated that over time, society has made positive, linear progress toward social issues, such as gender equality, racial diversity, and environmental protection. These estimates were often not aligned with reality, where much progress has been made in a nonlinear fashion. We also ruled out some potential alternative explanations (Study 3) and explored the potential correlates of linear progress beliefs (Study 4). We further showed that these beliefs reduced the perceived urgency and effort needed to make further progress on social issues (Study 5), which may ultimately inhibit people's willingness to act.
