Protocol
Set a review trigger before sunk cost chooses for you
Review the case while you can still change the case.
When it fits
- A long-running goal will accumulate time, money or identity investment before you know whether it still makes sense.
When to avoid it
- A review trigger reduces ambiguity; it does not remove judgment or prove that a goal should be stopped. Unexpected high-impact evidence should still trigger an earlier review.
Why it matters
Before investment becomes the main argument for continuing, choose a review trigger: a date, milestone, evidence threshold or major change in assumptions. At that point, reassess value, feasibility and opportunity cost using current evidence. Goal-adjustment research supports adjustment as a distinct self-regulation process; the exact trigger is a decision-design choice, not a scientifically optimal cadence.
Steps
- The next review can occur because a prewritten condition fired, not because frustration or investment finally became impossible to ignore.
An example
Review a six-month product experiment after the agreed usage signal arrives, not only after another six months of effort makes stopping emotionally expensive.

Keep this limit in mind
- A review trigger reduces ambiguity; it does not remove judgment or prove that a goal should be stopped. Unexpected high-impact evidence should still trigger an earlier review.

Evidence and sources
A 2026 meta-analytic review mapped 1,421 effect sizes from 235 studies and found that goal disengagement, reengagement and goal-striving flexibility have distinct antecedents and outcomes, while rating the accumulated evidence low to moderate overall.
High heterogeneity, publication-bias risk and heavy use of cross-sectional studies mean the evidence does not supply a universal rule for when an individual goal should be abandoned.
