Form an if-then plan linking the obstacle to a specific response
"If [obstacle occurs], then I will [specific action]" — this plan is what converts mental contrasting into behavior change.
Key takeaways
- What it is: "If [obstacle occurs], then I will [specific action]" — this plan is what converts mental contrasting into behavior change.
- Why it works: The Plan step in WOOP is an implementation intention. The if-then format creates a prospective memory link: when the identified obstacle arises, the planned response is retrieved automatically rather than assembled under pressure. Without this step, mental contrasting activates motivation and identifies the obstacle but leaves the behavioral response to in-the-moment improvisation — which typically reverts to the old pattern. The plan is what operationalizes the motivational energy.
- Evidence: Backed by randomized trials / meta-analyses.
- Avoid: Making the plan a motivational statement ("If I feel resistance, I will remember why this matters") rather than a behavioral specification — the plan must specify an action, not an emotional orientation.
Why it works
The Plan step in WOOP is an implementation intention. The if-then format creates a prospective memory link: when the identified obstacle arises, the planned response is retrieved automatically rather than assembled under pressure. Without this step, mental contrasting activates motivation and identifies the obstacle but leaves the behavioral response to in-the-moment improvisation — which typically reverts to the old pattern. The plan is what operationalizes the motivational energy.
How to do it
- 1Take the obstacle from the previous step.
- 2Write: "If [obstacle], then I will [specific, observable behavior]."
- 3The then-action must be concrete enough to execute without further deliberation: "I will [specific behavior]," not "I will try to handle it better."
- 4Rehearse the if-then plan once mentally, imagining the obstacle occurring and yourself executing the response.
What the evidence says
RCT / meta-analysisImplementation intentions show well-supported effects on goal attainment. WOOP trials that include the Plan step show stronger effects than mental contrasting alone.
Honest caveat: WOOP effects are studied primarily in shorter-term behavior change contexts; long-term maintenance data is thinner.

Common mistake
Making the plan a motivational statement ("If I feel resistance, I will remember why this matters") rather than a behavioral specification — the plan must specify an action, not an emotional orientation.
IX Coach converts the WOOP obstacle into a specific if-then plan with you, testing the plan for behavioral specificity before the session ends.
