  • The Dunning-Kruger effect can significantly hinder an individual's ability to learn and improve their skills in a given domain. Because the unskilled tend to overestimate their own competence, they may be less motivated to seek out learning opportunities or feedback that could help them recognize and address their limitations. This can lead to a lack of self-improvement and a perpetuation of the Dunning-Kruger effect. In contrast, more skilled individuals who underestimate their abilities may be more open to continuous learning and growth, as they recognize the complexity of the subject matter and the need to continuously expand their knowledge and skills.
