If you want a clear example of an ENFJ in action, Oprah Winfrey is it.
Firstly, the Feeling smacks you right in the face: she’s a dominant Feeling type, and her Feeling is Extraverted to boot. She’s got “community” and “cooperative spirit” (hallmarks of Fe) written all over her. But this is all beside the point.
Instead, what I want to note is the Introverted iNtuition (Ni)-as-Mother archetype that she seems to embody in many ways.
The Mother or Father archetype seems to be our Big Lesson in life — it’s what we use to mentor and support others. Ni, meanwhile, is all about making a mental shift and recontextualising. Put it all together and you end up with Oprah evangelising something like The Secret (i.e. the idea that the nature of thought determines the nature of reality).
Of course, The Secret appeals to many people and many types, but it’s particularly the sort of notion that would strike an ENFJ as something that needs to be preached far and wide, given that it taps right into their Father/Mother Ni. For an INTP like myself, on the other hand, it seems glib at best and dangerous at worst… but that’s just me.
The Opposing Personality is an archetype invented/created/discovered by John Beebe in his research on the roles the psychological functions play. With my own recent observations, I see the Opposing Personality as being a bit like the Hero’s dark twin — the figure symbolising the result of the making the wrong choices in life.
