Stealing Fire: How Silicon Valley, the Navy SEALs, and Maverick Scientists Are Revolutionizing the Way We Live and Work

by Steven Kotler

Kegan spent three decades tracking this group,32 seeing what happened to their psychological maturity and capacity along the way. He discovered that while some adults remained frozen in time, a select few achieved meaningful growth. Right around middle age, for example, Kegan noticed that some people moved beyond generally well-adjusted adulthood, or what he called “Self-Authoring,” into a different stage entirely: “Self-Transforming.” Defined by heightened empathy, an expanded capacity to hold differing and even conflicting perspectives, and a general flexibility in how you think of yourself, self-transforming is the developmental stage we tend to associate with wisdom (and Roger Martin’s Opposable Mind). But not everyone gets to be wise. While it usually takes three to five years for adults to move through a given stage of development, Kegan found that the further you go up that pyramid, the fewer people make it to the next stage. The move from self-authoring to self-transforming for example? Fewer than 5 percent of us ever make that jump.
