The introspection illusion is the tendency for people to overestimate their ability to know their own mental states and the reasons for their own behavior.
The introspection illusion can lead people to make inaccurate judgments about themselves and others, and can have negative effects on decision-making and problem-solving. For example, people may be overconfident in their own abilities or beliefs, and may be less likely to seek out new information or alternative viewpoints. This can lead to poor judgments and decisions.
One way to reduce the effects of the introspection illusion is to recognize its existence and to approach self-reflection and self-analysis with a healthy dose of skepticism. It is also helpful to seek out feedback from others and to consider multiple perspectives when making judgments about oneself and one’s own behavior.
