Immunity to Change (2009), the next book by Kegan and Lahey, revisits the immunity map of their previous book. The authors describe three dimensions of immunity to change: the change-preventing system (thwarting challenging aspirations), the feeling system (managing anxiety), and the knowing system (organizing reality).
They further illustrate their method with a number of actual case studies from their experiences as consultants, and they connect the method to a dialectic of three mindsets, called socialized mind, self-authoring mind, and self-transforming mind. (These correspond to three of the "evolutionary truces" or "orders of consciousness" in Kegan's earlier books.) Kegan and Lahey also borrow and incorporate some frameworks and methods from other thinkers, including Ronald A. Heifetz's distinction between technical and adaptive learning, Chris Argyris's ladder of inference, and a reworded version of the four stages of competence. They also provide more detailed guidance on how to test big assumptions.
