MBTI is not an intelligence test therefore having a T does not mean you have high IQ. It only means what value system you use (what values are most important to you). There are very smart people among Fs and Ts but they use different value systems to measure things up and make decisions so can come into misunderstanding over this. It is also not a test of aptitude - some people test ENTJ, the type called "The Executives", but never get to executive position in life but instead end up being housewives. Spending unwisely like I said it is not an IQ test, I have some INTJs in family, can say that yes they do this sometimes. And yes they can be quite lethargic at home too (that's your I me thinks).
I/E is pretty easy to tell - most people know of themselves whether they like to get to know as many people as possible or few people but very well. Whether they get energized by interacting with others or feel drained.
J/P well the Js tend to be more opinionated and set in their ways. Ps tend to be more random in their thoughts and feelings.
N/S divide is really easy to tell also. Ns like talking about the bigger picture and concepts and connecting things together. Ss like talking about here and now, current events and happenings, they pay a lot of attention to detail and in school excel in subjects like history.
