Personality and Persona are related words, but Second Vision uses them for different levels of claim.
The direct answer
Personality is a broad psychological concept for an individual’s characteristic patterns. In Second Vision, Persona is a narrower product term: a revisable working model assembled from task behavior, self-report, and optional outside perspective.
The APA Dictionary definition of personality is broader than a score or type. Its traditional definition of persona refers to the public face presented to others. Second Vision does not claim those dictionary terms are identical to its product model; it defines its use explicitly.
Why Second Vision uses Persona
A working model can keep source, context, support, limitations, and change history visible. That makes it possible to challenge a read when later evidence disagrees instead of treating the first result as an identity.
A game contributes only the behavior its registered method captures. A self-report contributes what you endorsed. Outside perspective contributes another person’s experience. None is silently promoted into the whole person.
What the distinction does not promise
Calling the model a Persona does not make it a diagnosis, a complete personality assessment, or a guarantee about future behavior. It is useful only to the extent that its claims remain traceable to suitable evidence.
