I'll embed the video for easy viewing.
I got half way through the video before I stopped watching. I think, very generally speaking, he's right - N - patterns, ideas, abstractions, S - concrete, details, etc. Where he starts to move in the wrong direction, imo, is when he starts getting into the finer differences into the thinking processes of both N and S. The outside/inside distinction he's making between Ns and Ss is not well thought out, as to me, that says more about I vs. E than it does about N vs S. Also the relationship between eye-movement and type is shaky and superficial, at best. If I were to make any observation at all, I'd say the eyes of an S type are usually far more alert while the eyes of an N type seem somewhat glazed over - this, however, isn't really noticeable in the way the eyes move than the energy or focus projected by those eyes. Pattern of movement in the eyes isn't a strong factor, if at all a factor, in determining N vs. S anyways. Most of his observations I feel are based off of his own very obvious superiority complex of being an N-type. It would have been more helpful to discuss cognitive functions anyway as opposed to looking just at the MBTI letters.
His presentation felt off-the-cuff, a bit careless, and essentially, needed to be thought out more. He draws his conclusions a little too quickly for my taste.
I'm too lazy to offer a rebuttal for each and every point he's made, but it's clear to me he is an N who looks down on Ss.
