What Would Need to Be True
Evidence from people who experienced NOI healing and then left: did their identities become fluid, or did they replace NOI-identity with another fixed identity?
Evidence that other identity-reconstruction systems (therapeutic, spiritual, institutional) share NOI's crystallization tendency, or whether crystallization is contingent to NOI specifically.
Direct comparison: a healing process that uses both identity reconstruction and nervous system integration (both NOI's mechanism and Janov's mechanism together). Does the outcome differ?
