Map your immunity to change

Surface the hidden competing commitment that keeps sabotaging a change you genuinely want.

Why it works

Kegan and Lahey argue that stuck goals persist because a hidden competing commitment — protecting against a feared outcome — actively works against the stated one, anchored by a big assumption you treat as fact. Mapping this makes the self-protective system "object," so you can test the big assumption instead of being unconsciously run by it.

How to do it

1. Name an improvement goal you keep failing despite wanting it.
2. List what you do (and don’t do) that works against it — your competing behaviors.
3. Infer the hidden commitment behind them, name the big assumption underneath, and design a small test of that assumption.

Evidence

The Immunity to Change method is Kegan and Lahey’s applied framework drawn from their developmental theory and refined through extensive practitioner use; it is well specified but supported mainly by case-based and theoretical evidence rather than controlled trials. (mechanistic)

Largely case-based; rigorous outcome trials are limited, so treat it as a structured reflective method, not a proven protocol.

Common mistake

Stopping at insight into the hidden commitment without testing the big assumption behind it. The change comes from running the small experiment, not from the diagnosis alone.
