Examine the evidence for and against the thought
Treat the thought as a hypothesis and find the actual evidence on both sides.
Key takeaways
- What it is: Treat the thought as a hypothesis and find the actual evidence on both sides.
- Why it works: Automatic thoughts feel self-evidently true because they are retrieved from memory rather than constructed by reasoning — and memory selectively surfaces information consistent with the thought’s conclusion. Deliberately listing evidence against the thought counteracts that confirmation bias by requiring the mind to search for disconfirming instances, which reduces the subjective credibility of the distorted interpretation.
- Evidence: Backed by randomized trials / meta-analyses.
- Avoid: Filling the "against" column only with wishful thinking ("things might work out") rather than actual past evidence ("last time I prepared, I performed well"), which does not shift the thought’s credibility.
Why it works
Automatic thoughts feel self-evidently true because they are retrieved from memory rather than constructed by reasoning — and memory selectively surfaces information consistent with the thought’s conclusion. Deliberately listing evidence against the thought counteracts that confirmation bias by requiring the mind to search for disconfirming instances, which reduces the subjective credibility of the distorted interpretation.
How to do it
- 1Draw two columns: "Evidence that supports this thought" and "Evidence that contradicts this thought."
- 2Fill both columns as honestly as you can — the supporting column first so you are not dismissing the thought prematurely.
- 3Rate the believability of the original thought after reviewing both columns (0–100).
What the evidence says
RCT / meta-analysisEvidence examination is the central technique of cognitive restructuring and is well validated within the CBT evidence base. Meta-analyses of CBT for depression and anxiety consistently show medium-to-large effects (d = 0.7–1.2), with cognitive restructuring techniques rated as key active components.
Honest caveat: Effect sizes are for CBT as a package; isolating the evidence-examination step’s contribution is methodologically difficult in dismantling studies.

Common mistake
Filling the "against" column only with wishful thinking ("things might work out") rather than actual past evidence ("last time I prepared, I performed well"), which does not shift the thought’s credibility.
