Quote from the link: Kegan describes three stages of adult development (numbered 3, 4, and 5). We could call them pre-rational, rational, and meta-rational. These stages are distinctive, internally consistent, relatively-well-functioning modes for organizing one’s thinking, one’s self, and one’s relationships. They might be described as “islands of psychological stability.” To progress from one island to the next, you must cross a heaving sea of psychological confusion, in which the previous mode no longer seems functional, but you cannot yet operate in the next mode reliably. These stage transitions are emotionally and cognitively difficult, and typically take several years, during which one may think, feel, and act inconsistently.

These ideas are not discussed enough, do you know any schools that teach it and give people a hope to achive meta-dationality? It is there a risk of people faking meta-rationality?
