The Dunning-Kruger Effect is a psychological phenomenon where people with low ability in a specific area overestimate their skills. This happens because they lack the knowledge to recognize their own incompetence. For example, someone who knows little about music might believe they can easily compose a song, not realizing how much skill and practice it actually requires. Conversely, those who are highly skilled, like professional musicians, often underestimate their abilities. They are more aware of the complexities involved in their craft, leading them to feel less confident. This effect highlights how self-awareness can vary greatly depending on one’s level of expertise.
