Answer:escalation of commitment.
Explanation:escalation of commitment refers to the irrational behavior of investing additional resources in a failing project. Even though it may seem obvious to outsiders that your business proposal has died, you might use all your time, energy and money to try to save it. Why can they see what you can't? The theory of commitment bias explores this phenomenon.
A prevailing theory about escalation of commitment points to our desire to be judged positively by others as a possible cause for this phenomenon. We don't want to admit that we made a poor decision, wasted our time or otherwise seem incompetent and incapable. We value routine and consistency, and it's easier to cling to these factors than to abandon ship.
