Why does emotional tolerance change fail?

The most common reason emotional tolerance change fails: Interpreting emotional discomfort as proof that the new evidence is wrong. This is the most common failure: you feel bad when confronting contradictory evidence, and your brain interprets the bad feeling as a signal that the evidence itself is flawed. You end up using your emotional reaction as epistemic data — 'this feels wrong, so it must be wrong' — which is the opposite of emotional tolerance.

The fix: Identify one belief you hold that you suspect might need updating. Write it down. Now write the strongest counter-evidence you can think of. Notice what happens in your body as you write the counter-evidence — tightness, heat, agitation, the urge to stop writing. Record those sensations alongside the counter-evidence. You've just mapped the emotional cost of evolving that schema. Sit with it for sixty seconds without resolving it.

The underlying principle is straightforward: Changing a deeply held mental model is uncomfortable — expect and accept this.
