Close. Robin Williams is an ENTP. You've been fooled by the Ne-Fe loop.
The ENFP type is often seen as an "introverted extrovert." Robin Williams could not possibly be described this way. He is an all-out extrovert, doubly so because of the Fe tertiary which subconsciously presses him to seek admiration and external validation. His Ti, that function which would keep Williams grounded in internal logic - an internal form of judgment - is extremely weak. Thus he relies on the judgments of others, externally, to fill him with the confidence he lacks. Robin Williams draws confidence from his audience, he feeds off of it, not from specific audience members but from (Ne) the general tone of the area he is addressing with his spontaneous comedy act.
"I absorb energy like a sponge everywhere I go. It allows me to see the world and my purpose in it." Zak Bagans, Ghost Adventures (INFJ)
I always thought he was an ENxP, until I interacted with him in person. He was rather private, neat, quick, intellectual, grouchy and high-maintenance.
