If a person is an introvert who extroverts or vice versa, do you think that the person is more likely to become their mirror or their contrary? Or something else?

That is, if there is a major attitude change in the person in which they redirect their energy to the inside or outside, do you think that the person switches to the auxiliary function or reverses their lead function?

To make this even simpler: does become or ?

No right or wrong answers that can be confirmed by fact as I know of, so who would like to discuss?
