Frame major decisions as experiments rather than commitments

An experiment has a built-in review point; a commitment resists revision even when the evidence against it accumulates.

Why it works

Commitment escalation and the sunk-cost fallacy cause people to persist in goal-pursuit long after the evidence suggests the goal was wrong or circumstances have changed. Framing a decision as a time-bounded experiment — "I will try this for six months and then evaluate" — keeps the decision open in a way that permits honest assessment rather than post-hoc rationalisation of prior investment.

How to do it

1. Before a major life or work decision, frame it explicitly as an experiment: "I will pursue X for Y months and then assess honestly."
2. Define in advance what evidence would lead you to continue, pivot, or stop.
3. Build the review date into the calendar before you start — do not wait for discomfort to trigger evaluation.
4. At the review, evaluate against the pre-defined criteria rather than against the emotional pull of sunk investment.

Evidence

Sunk-cost and commitment escalation research is well-established: people persist in failing courses of action when prior investment is salient, and pre-committing to evaluation criteria reduces this bias. (observational)

Some commitment (low optionality) is beneficial for goals that require sustained investment; experiment-framing is most valuable for goals with uncertain fit, not all goals.

Common mistake

Framing the experiment but not defining the success and stop criteria in advance — without pre-committed criteria, the review becomes a rationalisation of continuing regardless of evidence.
