What is the overconfidence barrier?

The overconfidence barrier refers to the phenomenon where individuals exhibit excessive confidence in the accuracy of their judgments and decisions. This often leads people to believe they are more knowledgeable or skilled than they actually are, resulting in inflated self-assessments. This overconfidence can manifest in various contexts, such as financial investing, personal judgments, or general knowledge assertions.

Individuals may have a strong belief that they understand complex situations or topics better than they do, which can hinder their ability to recognize their own limitations or the potential for error. This bias not only affects personal decision-making but can also contribute to broader social issues, such as the dismissal of feedback or expert input, leading to poor group decisions.

The other options do not accurately capture the essence of the overconfidence barrier. For instance, underestimating the accuracy of their judgments would imply a lack of confidence, which contradicts the concept. Moreover, while distrust in instincts and disregarding expert opinions can occur in some scenarios, these behaviors do not define overconfidence; rather, they are distinct cognitive biases or behaviors related to different contexts.
