multiplicity only happens when a person has undergone trauma, and is not the natural state of the mind. that is, by definition, a disorder. if nothing happened to make a personality not integrate, it integrates. you literally cannot be a multiple if you have an integrated personality because the term implies that your personality isn’t integrated.

The trauma based model pushed by the psychological institution is not the only cause of multiplicity. Non-trauma systems exist, and have existed for years, and do not require your or anyone else’s permission to exist.

For some insight into non-trauma multiplicity I recommend you visit http://multiplicity.livejournal.com/profile a forum which has existed for 15 years, where I have previously been a member.  

From the info page: “

Unlike some other communities related to multiplicity, this community does not concentrate on the Sybil-like, trauma-split/ dissociation model of MPD or DID. “
