This taxonomic question always comes up in HN discussions of personality type - see also, whenever Myers Briggs is discussed.

My take is that some people are well characterized by being on one side of a dichotomy - say, introvert/extrovert, or analytical/intuitive. They really get something out of discussions like in TFA, because they fit the class. And the fit can provide a powerful high-level diagnostic on a lot of otherwise inchoate feelings.

But, some folks are not well captured by the dichotomy - like yourself. These people tend to say that TFA is reductive and simplistic, and does not capture reality.

And both sets of people are right. For themselves.
