Too Long; Didn't Read
Sunk cost fallacy causes us to ignore the promise of a better experience in the future by making an attempt to negate a loss in the past. The more our past investment, the harder it is to abandon it. We fail to ask: Am I thinking forward or holding onto the past? What’s the opportunity cost to continue further? Will further investment fix the situation or cause greater loss? We are loath to leave it, because that would mean we had wasted our time or money, even though it is already gone.
