I believe this one is from Redirect (2011) by Timothy D. Wilson, though it could be from another source. It references Charles Cooley’s concept of the “looking-glass self,” which suggests that we form our self-concept based on how we think others see us—what Cooley calls “reflected appraisal.” We often adopt others’ views of our personality, preferences, and behavior. However, it’s not always wise to base our self-views on these reflections, especially if others don’t share our positive self-opinions. People may also hide their true impressions, particularly if they’re negative, leading to an inflated or skewed sense of our abilities.
