Given the way are brains work as human beings, when you put yourself in certain situations it will lead to false confidence. It will cause you to believe you are a better trader than what you are. In order to best understand the markets and ensure you give yourself true clarity and confidence, you must be fully aware of what hindsight bias is and how it works.
