What Cognitive Biases Are

Cognitive biases are predictable patterns in thinking that can distort how we interpret information, make choices, and judge people or situations. They are not the same as being careless or irrational; they are often the result of mental shortcuts the brain uses to simplify complex decisions.

In this lesson, you will learn what biases are, why they exist, and how they differ from facts, emotions, and general mistakes. You will also see why biases matter in everyday life, from first impressions and memory to work decisions and problem-solving.
