Prof. Robert Kegan sets up the environment for an inquiry on how come there is a gap between a person's real intention to change and what the person actually does. He recalls an illustration in which heart doctors advise their patients to take their medications as prescribed or literally die. Yet the follow up research shows that only 1 out 7 actually take their medications. The other 6 have just as great a desire to stay alive and yet risk death by not following their doctor. He proposes a deep need for some ways of thinking about what is in the way between a person's genuine intention and what the person is actually able to bring about. What is this gap -- 'Immunity to Change' -- and how can it be addressed?
