More likely it is a case in which it is exposed how pointless it is to identify fictional entities like "functions" in socionics. ENTp and ENFj are just types with a lot of traits in common, superficial and deeper ones. Intuition, Merry and Extrovert are all traits that can be identified in their own right, without regard to the "function" they give rise to in combination with other things.Whatever his type (clearly ILE ), this is an excellent example of how people often confuse the Demonstrative and Base functions when typing. I think it's an area the English-speaking Socionics community (including me!) could bear to work on and clarify a bit.
The pianist Glenn Gould is another person that leaves me undecided between ENTp and ENFj.
