Define the worst case in specifics

List the worst things that could happen if you take the action — concretely, not vaguely.

Why it works

Undefined fear is processed as diffuse threat, which the brain treats as larger and less escapable than it is. Writing each worst case as a specific, bounded event converts free-floating anxiety into a finite list you can actually reason about. Naming the fear is the step that makes it analyzable rather than paralyzing.

How to do it

1. Pick the action you’re avoiding and write it at the top.
2. List every worst-case outcome you can imagine, one line each, as concrete events.
3. Rate each on a 1–10 scale for both how likely and how permanent it really is.

Evidence

This is a practitioner exercise. Its plausible mechanism aligns with affect-labeling research — putting feelings into words is associated with reduced amygdala reactivity — and with the Stoic practice of premeditatio malorum. The fear-setting protocol itself is unstudied. Lieberman et al. (2007) showed with fMRI that verbally labeling an emotional image dampens amygdala activity, and Kircanski et al. (2012) found the same labeling improved outcomes during exposure — direct support for why naming a fear in specifics, rather than leaving it diffuse, defuses it. (mechanistic)

No formal outcome trials of "fear-setting" exist. Treat the likelihood/permanence ratings as a reasoning aid, not data.

Common mistake

Listing fears as vague headlines ("it’ll be a disaster") instead of specific, ratable events — which keeps the dread global and unbeatable.
