The tendency to overestimate one's own qualities and abilities relative to others. Most people rate themselves as above average on desirable traits such as intelligence, driving ability, and social skills — a statistical impossibility. This bias is robust across cultures, though its expression varies.
In surveys, approximately 90% of drivers rate themselves as above-average drivers. Similarly, most professors rate their teaching as above average, and most employees rate their performance as better than their peers'.
In an anonymous workplace survey, 87% of employees rated their communication skills as above average compared to their colleagues, even though by definition only 50% can be above the median. When the results were shared, most employees assumed the others were the ones inflating their scores.
A first-year medical student, after completing a single semester of coursework, tells a family member that he could probably spot a misdiagnosis better than a general practitioner. He significantly overestimates his budding knowledge relative to years of clinical training and experience.
Binary (yes/no) questions an LLM must answer to identify this aspect:
Does the person rate themselves above average without objective evidence?
Type: binaryAre self-assessments significantly more positive than peer assessments?
Type: binaryIs there an assumption of being better than most people at a given task?

This bias is robust across cultures, though its expression varies.
People tend to focus on their strengths when self-evaluating, use self-serving definitions of traits, and have limited information about others' abilities. Motivational factors also drive people to maintain positive self-views.
Seek objective metrics and external feedback rather than relying on self-assessment. Compare your performance against concrete benchmarks rather than your impression of how others perform.
This bias affects salary negotiations, team dynamics, academic self-assessment, and driving behavior. It contributes to overconfident risk-taking in finance and entrepreneurship.
