Commitment bias describes our unwillingness to make decisions that contradict things we have said or done in the past. This is usually seen when that behavior occurs publicly. Sunk cost fallacy is a form of commitment bias. It refers to how we feel the need to follow through with something once we’ve invested time and or money into it. To avoid commitment bias, remember that it’s always better to make a decision based on the present and logic than a decision based on consistency with your past behavior. Instead of worrying about what other people will think of you if you admit (such as that you made a mistake) focus on the benefits that will come from changing your behavior NOW.
