Bluffgenic

undefined:

A bluffgenic headmate is one that forms due to their system or another member being persuaded of their existence. Another person may "bluff" that this headmate already exists, and if they believed, the headmate in question may form to affirm the bluff or in response to the belief.

Mendabased similarly refers to headmates that are influenced by belief of false information, though it refers to attributes rather than their existence in general.

This may be considered an origin or a formation mechanism.
