i don't see him as Fe inferior, nor do i see him as Ti dominant. his eyes aren't steely like beck (who i speculate is intp 4w3).
i think he's Ne dominant, he's too loose to be Ti first. he's not a joke technician, he's a guy with hilarious ideas. his delivery is a huge part of it, and his delivery is so off the cuff entp to me. i've seen entps who are more traditionally shy than any of the intps i know. the intps i know are more awkward than shy, they don't pay as much attention to social niceties (inferior Fe) so they look so steely-eyed at you. 4w3 would temper that, but for intp 3w4 is the only one that really is impossible for me to tell the difference between entp and intp. at that point, i ask about Si memory first and foremost, along with judging overall flexibility (which is difficult to discern). the intps ignore you, the entps notice and respond to you with a hugely varying set of approaches. the intps seem colder, the entps i've known have way more self-awareness/self-consciousness, and a different kind of energy as a result (altho i know a probable 3w4, a 4w3, a 7w6, vaguely know one 7w8, and one as of yet untyped).
