Cognitive Bias in Self-Perception

Summary

This book contains the following titles:

- The Overconfidence Bias: Overconfidence is a cognitive bias that affects the way we perceive our abilities, knowledge, and future outcomes. It leads individuals to overestimate their competence and the precision of their knowledge, often resulting in flawed decision-making. At its core, overconfidence is an inflated sense of self-assurance that distorts reality. While a certain level of confidence is essential for success, excessive confidence can cloud judgment and lead to risky choices.

- The Dunning-Kruger Effect: The Dunning-Kruger effect is a cognitive bias that leads individuals with limited knowledge or ability in a particular area to overestimate their competence. Named after psychologists David Dunning and Justin Kruger, who first identified this phenomenon in 1999, the effect reveals a paradox in human cognition: the less people know, the more likely they are to believe they know everything. Conversely, experts in a field tend to underestimate their abilities, assuming that others possess the same level of expertise. This bias is not only fascinating from a psychological standpoint but also carries significant implications for personal, professional, and societal development.
