i typed silverman as IEI some time ago. i don't have any good reasons why that's any better than rick's typing of EIE, nor do i object at all to the latter, but i don't know why rick thinks EIE is more appropriate.
The most obvious thing we learn from Rick's typing of her as ENFj, is that she is likely not an ENFp. If she was, Rick would easily have picked up on the identical relation.

under no circumstances IEE; her brand of humor is provocative, emotionally colorful (she doesn't at all shy away from expressive caricature for laughs), and widely directed towards conveying social awkwardness and absurdity. basically a typically beta "fart jokes" sense of humor.
I'll agree that it's Ti/Fe humor. However, Alphas are commonly said to be even more "childish" than Betas. Beta NFs tend not to be as unrefined as to resort to "fart jokes" at all. I think most of the Beta NFs here would take insult to the suggestion that their humor is of a "fart joke" level.
