So I am writing a story where the magic system is based off of personality traits of the individual. I would like to base it off of something like the Big Five model or the Myers-Briggs model or even the four temperaments model. I am going to pick one eventually to base it off of, that is not really the question. What I am more concerned about is if using the same terminology as these personality models would be frowned upon.
So what I mean by that is take the Big Five: Openness, Conscientiousness, Extraversion, Agreeable, and Neurotic (OCEAN). Can I use the same terminology (OCEAN) to describe the traits that people have or do I need to find other words (i.e. change Extraversion = Outgoing, etc.) or do I need to come up with my own system all together?
