Psychologists said most people overestimate their ability to change their own personalities far more than is actually possible [1, 2].
This discrepancy in self-perception matters because it highlights a fundamental gap between how individuals view their potential for growth and the scientific reality of personality stability. When people believe they can fundamentally alter their traits, they may pursue unattainable goals or misinterpret the nature of personal development.
Experts said this phenomenon is the "better-than-average effect" or "wishful narcissism" [1, 2]. This cognitive bias leads individuals to believe they possess more positive traits or capabilities than the average person. In the context of personality, it manifests as a belief that one's core nature is more fluid and changeable than evidence suggests [1, 2].
According to psychologists, this bias exists because humans are deeply invested in flattering self-illusions [1]. These illusions serve as a psychological buffer, allowing individuals to maintain a positive self-image. Consequently, people routinely overestimate various personal traits, including intelligence, morality, and attractiveness, alongside their ability to change their personality [1].
While personality is not entirely static, the degree of change typically possible is lower than what individuals perceive. The tendency to overestimate this flexibility is a widespread human trait rather than an isolated occurrence [1, 2].
“People overestimate their ability to change their own personalities far more than is actually possible.”
This research suggests that the popular narrative of total personal reinvention may be more of a psychological comfort than a scientific reality. By identifying 'wishful narcissism,' psychologists are illustrating how the human brain prioritizes a positive self-concept over an objective assessment of trait stability, which may impact how people approach therapy, self-improvement, and long-term behavioral goals.
