Aka, "Mastermind"! Which I find incredibly amusing. However, I am offended at being categorized with Ayn Rand.
And, sure enough- I'm in natural sciences.
Given my low rating in J, I think that I would be best described as an INTJ/INTP hybrid- which actually makes sense and is quite possible if you understand how such personality testing works. With those high scores in INT there is no doubt that I'm a "Rational" but, frankly, the TypeLogic description of INTP "Architect" sounds much closer to me than the INTJ "Mastermind". I also seem to remember scoring that way the last time I took this test, decades ago.
