I think we are measuring if the person is living a life as their true self. Some types must be pretty much lying to themselves if they start doing empirical dry research, because they were born to be good at interacting with people. If a SEE becomes a math researcher, he/she will stay at the bottom of the food chain in that community. They will only be able to cope if they are highly intelligent, in which care they would have been better off as a psychology researcher.

Other types are truly stupid if they become a teacher/salesperson, because they have to try to be something they are not and they'll end up frustrated and tired with life.


Doing what you were intended to do in the first place will increase the chance of happiness and success.
