Postpone worry as an experiment to test controllability

Deliberately defer a worry for 30 minutes to prove to yourself that worry is more controllable than you believe.

Why it works

The negative meta-belief "I can’t control my worry" is behaviorally tested by the postponement experiment: if you can postpone a worry, even briefly, that is direct evidence that the worry is controllable. The experiment is not about reducing worry — it is about gathering evidence against the uncontrollability belief that sustains the worry cycle.

How to do it

1. When a worry arises, acknowledge it: "I notice this worry about X."
2. Set a specific postponement: "I will think about this at 6pm." Write it down.
3. Return to the present task. At 6pm, review your list — and notice how many of the worries still seem as urgent.

Evidence

Worry postponement (stimulus control for worry) has its own controlled trial evidence from Borkovec's work; the MCT framing of it as a meta-belief experiment rather than a symptom-management tool is Wells's specific contribution and is supported by MCT trials. (rct)

The postponement experiment is well supported; whether the meta-belief framing specifically (vs. simple postponement as symptom management) produces distinct benefits is not separately trialed.

Common mistake

Using the postponement as a suppression tool ("I’ll get to it later, now stop thinking about it") rather than as a controllability test — the lesson is "I could control when I worried," not "I avoided worrying."
