What would they then be?
Also, it's less about "emotions" being Fe, than about him knowing very well "how to push buttons" - which is a characteristic of strong Fe.
You see, in my opinion, the second clip you posted already qualifies. If you don't see that as being SEI, then we disagree on what SEIs are like or can be like.
He does not show Fe as, say, a ESE or EIE would. Yes, because I think he's SEI, not ESE.
I am not just being stubborn. I am seriously thinking about the SLI possibility. But those two clips just reinforced my SEI opinion.
I don't see that as really "analytical tendency"; he's explaining in detail the tricks of a trade he's worked in for decades. Imagine a SEI car mechanic - I suppose you can imagine that such exist? Would a SEI car mechanic be unable to talk at length about cars in the same fashion? Or your image of SEIs is that, even when in a serious interview, they have to be joking all the time?
Why should it be a sign of Delta over Alpha? How would you argue it?
No. I totally disagree with you there. What he actually said, very clearly, is that he does not care about the details of the plot, as to why something happens or not. He just said he didn't care about that; he cared about the emotional response of the audience. That was the "technique" he was talking about. He saw his movies as a collection of images aiming at creating specific emotional responses, on a moment-by-moment basis, without caring about whether the plot, the content. He even compared Psycho to an amusement park thrill ride - now that is an indication of Alpha>Delta.
