Map best case, worst case, and most likely case
Write out all three scenarios to reanchor your thinking in the probable, not just the feared.
Why it works
Anxious thinking has a selective attention bias toward worst-case scenarios, leaving the rest of the probability distribution invisible. Writing out all three cases forces the brain to actively construct outcomes it was ignoring, which shifts the focal point from the tail of the distribution to the center — where the most probable scenario lives.
How to do it
- For the situation you are worried about, write out: the best realistic outcome, the worst realistic outcome, and the most probable outcome.
- Circle the most probable.
- Ask: "Am I planning for and reacting to the most probable, or the worst?"
Evidence
The three-case mapping is a standard CBT thought-record component targeting selective attention to threat. It is part of validated CBT protocols for generalized anxiety and health anxiety with RCT support. (rct)
The three-case technique is embedded in multi-component CBT programs; isolated evidence for it as a standalone intervention is limited.
Common mistake
Writing a "most likely" case that is only slightly better than the worst case because anxiety has contaminated the middle estimate — the most likely case needs to be realistic, not optimistic, but also not catastrophe-adjacent.

More practices for Decatastrophizing, Made Practical
- Ask: what is the actual probability?
Explicitly estimate the realistic likelihood of the feared outcome — not how it feels, but what the evidence says.
- Ask: could you cope even if the worst happened?
Catastrophizing also underestimates your coping capacity — examine that half of the equation.
- Ask: how will this look in one year, five years?
Project forward to check whether the catastrophe still looks catastrophic from a temporal distance.
- List evidence for and against the catastrophic belief
Treat the worst-case belief as a hypothesis and gather the actual evidence.
- Find base-rate data to calibrate the threat
Look up how often the feared outcome actually happens to people in similar situations.
- Scale the catastrophe on an actual severity scale
Rate the feared outcome on a 0–10 severity scale, then compare it to things you know are 10/10.
