Map your immunity to change

Find the hidden competing commitments that are holding a desired change in place.

Why it works

Kegan and Lahey’s "immunity to change" model holds that most persistent failures to change are not motivational failures but structural ones: the person holds a competing commitment that makes the change threatening. The immunity map makes this structure visible. A person who wants to speak up more but also (invisibly) needs to be liked cannot simply decide to speak up — they need to see the competing commitment and examine its underlying assumption.

How to do it

1. Name one important behavior you want to change but haven’t. This is your improvement goal.
2. List what you actually do instead (the immune behaviors). Be specific and honest.
3. Ask: "What do I fear would happen if I stopped these behaviors?" The fears point to hidden commitments.
4. Frame the hidden commitment: "I am also committed to _____." Now examine the big assumption underneath it.
5. Design a small, safe experiment to test whether the feared outcome is actually as catastrophic as the immune system predicts.

Evidence

The immunity to change framework has been used in organizational and coaching settings and tested in applied studies. One study found it produced meaningful change in goals that had been stuck. A study of educational leaders documented how surfacing and overturning their immunities shifted behavior that had resisted ordinary professional development. (observational)

The evidence base is primarily practitioner reports, case studies, and limited applied research; it has not been tested in randomized controlled trials.

Common mistake

Listing fears that are really just obstacles rather than competing commitments — a competing commitment is something you are genuinely protecting, not merely something difficult.
