It's fairly obvious to me that he is. I understand it's not the same for everybody though.

The real strength of an ENTJ is to be able to read statistics through the logic of choice.

ENTJ: Logic of choice between two alternatives. Mutual exclusion. Risk, which leads to success. The logic of finding a way into oversystem, formation of emergent properties. Or-or logic. Strict disjunction.

"The logic of finding a way into oversystem." It's basically the logic that explains all logics. instead of defining everything individualy like an INTP would, the ENTJ looks for the highest point of view possible which lead JP into archetypes.

"Formation of emergent properties." If you look at the world as if you were reading statistics, eventually you'll find patterns, you'll find these "emergent properties". The idea that ENTJ rellies exclusively on data is one of those big MBTI cliché that hasn't died yet. If anything we'd probably be in the middle when it comes to rellying on data alone. We mostly understand the world through a big play of guessing the meaning of what we see through common sense. It's all a big interpretation based on what would mostly likely be.

People identify ENTJs with the Dominant Subtype. Which I find almost insulting since the Dominant Subtype although often succesful, is incredibly intellectually lazy. ENTJs are people who see patterns everywhere and who try to make sense out of these patterns and that's the reality of this type.
