The MBTI does not dictate the way in which you or other people behave. You behave in different ways in different situations. Whilst some questionnaires and personality models are concerned with behaviour, the Myers Briggs model of personality is concerned with your inborn preferences. Your behaviour often, but not always, indicates what those preferences are. Every individual is different.

You adapt your behaviour to suit the situation - when going to work, you might adopt your "professional" persona, for example. But at home, you might adopt your "parent" or "spouse" personas, depending on who is in the room. Some of these personas may be close to the 'real you', whilst others may be quite different. The four letter Myers Briggs code is meant to reflect the "real you" and not just one of your personas. Bad Joke: What might seem to be the preferences of a tribal native, when that native is no good at "hunting"? Vegetarianism.
