Can she really be an ENFP?

[Eric B]

Could be either ENFP or ENTP

-She thinks she's always right, even when she behaves in a morally questionable manner;
-She has some strong emotional outbursts that make her look childish at times;

Could still be an ENTP - how old is she?

Particularly, that sounds like it could be tertiary Fe.

Also, there seems to be some of the competitiveness in some of the other descriptions.

Otherwise, an obvious Get Things Going or Sanguine. (ESF/ENP which are the types being suggested).
