Biases can be of two types: cognitive biases, which stem from faulty reasoning, errors in processing information, and memory errors; and emotional biases, which arise from emotions rather than any conscious thought. Between these two types of biases, cognitive biases are easier to correct, through understanding one’s mistakes and learning from them.
