To add to case for INTP JP- he certainly has a hyper developed introverted thinking capacity. In his own words, he thinks things through “all the way to the bottom,” and in Joe Rogan podcast he said he rewrote every line of his first book Maps of Meaning at least 15 times each to make sure the argument was defensible.
As for his Ne, that’s all you would see from an INTP in television, since that’s what he extroverts. But I can easily imagine JP spending most of his waking hours alone reading and thinking deeply. He’s not rambunctious and playful the way we ENTPs typically are (think Richard Feynman).
Would love to ask him one day
