- IDEA 1 OF 8
We resist change for hidden reasons
Kegan and Lahey argue that people often fail to change even when they sincerely want to, because a hidden mental immune system protects them from what they fear.
Understanding this system is the key to real change.
- IDEA 2 OF 8
Adaptive challenges need new thinking
The authors distinguish technical problems, solved with new skills, from adaptive challenges, which require changing mindsets.
Many personal changes are adaptive. In the authors' view, learning a new skill is not enough when the real obstacle is a belief that we hold without noticing it.
- IDEA 3 OF 8
Start with an improvement goal
The authors' four-column map begins with a goal you genuinely want to achieve.
It should matter to you. In the authors' view, if the goal is not truly important to the person, then the rest of the process will not work well.
- IDEA 4 OF 8
List what you do instead
The second column lists behaviours that work against the goal.
Honesty is essential. In the authors' view, listing what we actually do, and not what we intend, shows how we may be undoing our own goal.
- IDEA 5 OF 8
Find hidden commitments
The third column identifies hidden competing commitments, fears or needs that these behaviours protect.
They explain resistance. In the authors' view, these hidden fears work like a quiet brake, and they explain why people resist changes they sincerely want.
- IDEA 6 OF 8
Uncover big assumptions
The fourth column reveals big assumptions, beliefs that make competing commitments feel necessary.
These assumptions hold the system in place. In the authors' view, a belief such as I must never be seen to fail can keep people from changing, even when they truly want to.
- IDEA 7 OF 8
Test assumptions safely
The authors suggest testing big assumptions through small experiments.
Evidence can loosen their grip. In the authors' view, a small and safe test lets a person check whether a feared result really happens, so the belief can be revised.
- IDEA 8 OF 8
Change becomes possible
As assumptions are tested and revised, people can change behaviour.
The immune system relaxes. In the authors' view, once the hidden beliefs are seen and tested, the old behaviour loses its hold, and new habits become easier.
