Cognitive bias mitigation is a way of reducing the chances that a person will make decisions that are based on their own past experiences and preconceptions rather than on evidence. It's something that happens to everyone, even though we may not always realize it. To mitigate cognitive bias, a person needs to try to be as objective as possible and make decisions based on facts and research rather than on their own personal opinions and biases. For example, if you are trying to decide between two job candidates, it is important that you look at their qualifications and job experience objectively, without letting your past experiences with similar candidates cloud your judgment.
