Decentering: "Thoughts are not facts"
Treat thoughts as mental events to be observed, not truths about yourself or your situation.
Why it works
In depression, negative thoughts feel like accurate descriptions of reality ("I am worthless"). Decentering shifts the relationship so thoughts are observed as transient mental events: "I notice a thought that I am worthless." This does not dispute the thought’s content; it changes the attachment to it. Research shows decentering mediates MBCT’s preventive effect — people who decenter more show less relapse.
How to do it
- When a strong negative thought arises, prefix it: "I am having the thought that..."
- Notice the thought as an event in the mind, similar to a sensation in the body.
- Ask: "Is this thought a fact, or is it a thought that feels like a fact?"
- Return to a sensory anchor (breath, feet) rather than arguing with the content.
Evidence
Decentering is identified as a primary mechanism of MBCT in process research. Increases in decentering scores over the 8-week program mediate reductions in depressive relapse. This is one of the more specific mechanism findings in the MBCT literature. (observational)
Mediation analysis demonstrates association, not experimental isolation of decentering as the active causal ingredient.

Common mistake
Turning decentering into arguing with the thought ("That’s not true, I’m not worthless") which keeps the mind engaged with the content rather than changing the relationship to it.
