top 2 % of the earth's population. In terms of IQ and intellect.
That is my definition of a superintelligent genius.
Ok. Then, I wouldn't say that INTPs are more likely to become geniuses but geniuses are more likely to become INTPs. Unless you spill the question, I won't be able to vote.
From an evolutive aspect, intelligence is about reacting to aggression as soon as possible .. A better anticipation of future aggressions calls for higher levels of abstract reasoning, thus favouring a better potential understanding of our complex environment (let's say, a better paradigm), which is not a purpose but a collateral effect, actually. My point of view.
That said, an INTP has the most abstract preferences. He enjoys living abstract (paradigm-oriented/energized), thinking abstract (speculative, non-empirical), judging abstract (analytical, non-affective support) and reacting abstract (paradigm-oriented adaptation, non-environmental restructuration).
Reaching a superhigh level of abstract reasoning calls obviously for predispositions and a lot of self-engineering. Looking at human babies, they are all epic ESFJs. It's not easy even when being predisposed and there have to be a part of preference, therefore the most powerfull abstract thinkers are more probably INTPs. My viewpoint again.
However, if his abstract preferences take too much mental energy at the expense of his concrete-thinking devices, a superhigh abstract INThinkerP is more likely to not concretize himself and remains a theorical (haha) genius, spending his life to reinvent the heel, lacking the passion to concretize a big idea, or the agressiveness to defend his paradigm, etc .. My viewpoint, again and again.
I agree to say that every MBTI orientations lack something. Mankind reached a point where everyone lacks energy to develop every aspect of themselves, because our brains are ridiculously inefficient and energy-consuming. Some of us are more lucky, though. The ideal would be to excel at every dynamic .. still, I think it's more logic that someone who excels everywhere would prefer to rely on his more advanced devices (abstract thinking/judgment NT) to structure his paradigm.
