Overconfidence Effect

Definition

The overconfidence effect is a cognitive bias where an individual's subjective confidence in their judgments or abilities is greater than the objective accuracy of those judgments. This phenomenon often leads people to take excessive risks or make poor decisions, as they may underestimate uncertainties or overestimate their knowledge and skills. It plays a significant role in decision-making processes and can hinder the ability to overcome cognitive biases and mental blocks.
