What is cognitive bias?

Cognitive bias refers to a systematic deviation from rationality in judgment. This means that when individuals make decisions or form beliefs, they often rely on subjective factors such as emotions, personal experiences, and preconceived notions rather than objective evidence or logical reasoning. This phenomenon can lead to illogical conclusions, skewed perspectives, and the perpetuation of stereotypes or misunderstandings, as it affects how information is processed and interpreted.

Understanding cognitive bias is crucial in various fields, including psychology, as it affects human behavior and decision-making. It highlights the limitations of human reasoning and the influences of cognitive shortcuts or heuristics that people adopt. By recognizing cognitive biases, individuals can work towards making more informed and rational decisions, allowing for better outcomes in personal and professional contexts.
