The Dunning-Kruger effect is a cognitive bias first identified in 1999 by psychologists David Dunning and Justin Kruger. The phenomenon describes a ‘dual burden’ where individuals with limited knowledge or skills overestimate their own competence because they lack the very skills required to recognize their own errors or the true expertise of others.

This bias often results in low-performing individuals rating themselves above average in areas such as logic, grammar, and humor, while high-performing experts may exhibit more caution or doubt due to their understanding of a subject's complexities. Online platforms, characterized by anonymity and algorithmic echo chambers, can amplify this effect by allowing individuals to express unfounded confidence after only brief exposure to a topic.
