Find base-rate data to calibrate the threat
Look up how often the feared outcome actually happens to people in similar situations.
Key takeaways
- What it is: Look up how often the feared outcome actually happens to people in similar situations.
- Why it works: Availability heuristic-driven probability inflation can be partially corrected by base-rate information. When you have vividly imagined a plane crash, it feels far more likely than statistics justify. Exposure to the actual frequency — from a credible source — provides the outside-view reference that counteracts the inside-view inflation of anxiety.
- Evidence: Plausible mechanism, limited direct outcome data.
- Avoid: Searching for the data in a way that finds worst-case examples ("plane crash survivors") rather than representative base rates, which confirms the fear rather than calibrating it.
Why it works
Availability heuristic-driven probability inflation can be partially corrected by base-rate information. When you have vividly imagined a plane crash, it feels far more likely than statistics justify. Exposure to the actual frequency — from a credible source — provides the outside-view reference that counteracts the inside-view inflation of anxiety.
How to do it
- 1Identify the specific feared outcome and frame it as a question with a quantifiable answer.
- 2Look up an actual base rate: "what percentage of X leads to Y?"
- 3Compare the number to your subjective estimate and update accordingly.
What the evidence says
MechanisticInside-view vs. outside-view reasoning is a well-studied aspect of judgment under uncertainty; base-rate neglect is a documented contributor to probability overestimation. Using outside data to correct inside-view estimates is a calibration technique with support from decision science.
Honest caveat: Decision science supports the mechanism; application to anxiety-specific decatastrophizing in clinical settings is a reasoned extension rather than a separately trialed protocol step.

Common mistake
Searching for the data in a way that finds worst-case examples ("plane crash survivors") rather than representative base rates, which confirms the fear rather than calibrating it.
