Feynman is typed as an ENTP, but I was watching a video of his in which he states that he abhorred the humanities and arts and virtually any non Physics/Math based class when he was at MIT. He then claimed that he broadened his interest later in life. I was wondering if he may have been a Ni user and possibly a INFJ due to his obvious Fe? An argument exist that he was an ENFJ. A smart INFJ would be mis-typed as a NT.
