Escalation of Commitment

mechanism

An initial investment can turn later decisions into rescue missions: each new commitment is judged by whether it vindicates the last one, not whether it is now the best option. The escape is to reset the choice around present costs, benefits, and alternatives.

A monitor did not lead to a replacement monitor. It helped lead to four MacBooks in roughly two and a half years—a chain of purchases made in the shadow of the first decision.

When rescue replaces choice

The first investment creates something psychologically unfinished: money already spent, a setup that ought to work, or a choice that still needs to be proved sensible. The next purchase is therefore framed as a fix. Once that fix also disappoints, abandoning the whole chain feels costlier because there is now even more to justify. Commitment escalates one seemingly corrective step at a time.

The crucial distortion is the comparison being made. Instead of asking, “What is the best option from here?”, you ask, “What will make my earlier choice pay off?” Past expenditure becomes an unofficial requirement imposed on the present.

Where it shows up

The four-MacBook monitor

The monitor story compresses the mechanism into one absurd outcome: a peripheral purchase becomes the anchor for repeated computer replacements. Each machine can look like a local solution even while the sequence as a whole signals that the original setup should have been reconsidered.

Persistence is not automatically escalation

Continuing can be rational when a new investment has strong prospective benefits. The model applies when previous spending is doing the persuasive work—when you would reject the next step if you were choosing fresh today.

Price the next step as a fresh purchase

Before paying for another fix, write down the options available now—including abandoning or replacing the original setup—and compare only their future costs and benefits. If the rescue option wins only after you mention what you have already spent, do not buy it.
