Immunity to Change Map
Also known as: ITC map, Immunity map
A four-column mapping process that surfaces why sincere improvement goals stall: (1) the commitment to improve, (2) what I do/don't do instead, (3) hidden competing commitments protecting me, (4) the big assumptions underneath them. The map then drives small, safe tests of the big assumptions over weeks — a structured route from insight to actual change.
Prerequisites
- A real improvement goal the person actually cares about (not an assigned one)
- If maps are shared in pairs/groups, sharing depth stays at the owner's discretion
- Column 3 touches self-protective anxieties by design; go at the owner's pace and never diagnose someone else's map
- Solo use with the book is legitimate; organizational use with power differentials needs care about who sees maps
Practical
- Time
- 90-180 min + 60 landing
- Group
- 1–30 · individual, pairs, small-group
- Settings
- in-person, online, self-guided
- Materials
- Four-column worksheet; privacy for honest work
- Mechanisms
- cognitive-reframing, narrative-identity, emotional-processing
- Change scope
- state → capacity · program-embedded (initial mapping, then assumption-tests over 8–12 weeks)

Listed in the IDG Phase 2 Toolkit as a core method. The clearest example of a tool whose real unit is a process, not a session: the map is one sitting, the change is the testing period. Its developmental ambition (Kegan's adult-development lens) is why change_scope includes capacity.
