Study participants were presented with a series of scenarios and asked to describe how they would respond and how others might respond to each scenario.
The study revealed that participants often thought other people would make similar decisions as them.
Individuals overestimate how much their opinions, beliefs, preferences, and behaviors are shared by others.
