What does illusion of control bias refer to?

Illusion of control bias refers to the cognitive tendency where individuals believe they have influence or control over outcomes that are actually beyond their ability to affect. This phenomenon often manifests in scenarios involving chance or randomness, such as gambling or investing in the stock market. Individuals may feel that their decisions or actions can sway uncertain results even when there is no actual correlation between their behavior and the outcomes.

Understanding this bias is crucial for investors and financial analysts since it can lead to overconfidence in their capabilities and decision-making processes, potentially causing poor investment choices and increased risk exposure. Recognizing that not all outcomes can be controlled is vital for developing effective strategies and maintaining realistic expectations.

The other concepts are related but do not accurately capture the essence of the illusion of control bias. The belief of having no influence over outcomes is the opposite of this bias. Overestimating the power of random events discusses a different cognitive issue — misjudging the effect of chance rather than believing in one's control. Relying solely on historical data pertains to a distinct cognitive bias called hindsight bias, where past results influence present decisions, which is not the same as the belief in having control over uncontrollable outcomes.
