Answer:
People tend to make systematic and predictable mistakes in their thinking. These mistakes are called biases.
Explanation:
Humans are not perfect decision makers. Everyday humans make numerous decisions and try their best to be rational. But many times, our cognitive limitations prevent us from doing so. In systematic and predictable ways, we do drift away from perfection. Even if we take each step properly to make a decision by first defining the problem, then thinking of alternatives for the solution and then take a decision, one is bound to get affected by cognitive thinking. Such mistakes that humans make are called biases. They affect the judgement of even a very talented human being.
