Humans easily access reflexive level recognizing base drives. Connective level adds empathy for others' drives. Control level enables Machiavellian manipulation of situations. Rule level invents morality to prevent societal collapse. Achievement level embraces reason, science, and Enlightenment principles. Pluralist level accepts subjective truths and postmodern skepticism. Higher levels 7-9 poorly defined and iffy. Only 5% estimated at level 7, likely under 1% in reality. Smart non-introspectors rarely exceed level 5. Levels 1-6 map to Kegan stages. Metacognitive advance equals increased perspective layers. g correlates 0.5 with level access. Age, peers, and environment drive level adoption more than introspection. Level access correlates weakly with life success. Upper Spiral Dynamics levels exploit insecurity with vague appeals. Self-perception style poorly predicts post-level-6 development.
