Answer:
Escalation of commitment or commitment bias.
Explanation:
Escalation of commitment is a human behavior pattern in which an individual or group facing increasingly negative outcomes from a decision, action, or investment nevertheless continues the behavior instead of altering course; meaning the individual or business continues to invest additional resources in an apparently losing proposition, influenced by effort, money, and time already invested. The group/individual maintains behaviors that are irrational, but align with previous decisions and actions. Economists and behavioral scientists use a related term, sunk-cost fallacy, to describe the justification of increased investment of money or effort in a decision, based on the cumulative prior investment ("sunk cost") despite new evidence suggesting that the future cost of continuing the behavior outweighs the expected benefit.
