Kiersey explains four types of intelligence: Strategic (NT), Logistical (SJ), Diplomatic (NF), and Tactical (SP). The basic idea is that we each have a preference for those four in order. So, the order for NTs is first strategic, then diplomatic, then tactical, then logistical. For me, that's relatively true in that logistical is last though I would put tactical ahead of diplomatic.
He further defines it as follows: "The strategic intelligence of rationals (NTs) is shown in their ability to work with systems, that is to figure out complex ways and means to accomplish well-defined goals, whether as a Coordinator formulating complex orders, or as an Engineer constructing complex organizations".
An example (since you are an INTJ): "Masterminds (INTJs) are the masters of sequential order, that is, entailing successive operations in a complex project so that all probable contingencies are anticipated and all appropriate measures are taken to keep the project on course. INTJs see the whole picture with eagle-eyed clarity and when put in charge begin immediately formulating their strategies, arranging their priorities and making their flow charts in order to achieve their goals with a minimum waste of time and resources."
I think it's mostly right. The flowchart is more of a Ti thing but we do develop plans and all the rest of the stuff he says.
