RE: MBTI: My Personality Type
They are the best villains though! INTJs are often seem outwardly cold, are often highly intelligent, rational to a fault, and highly confident in their ability. These traits make them complex and somewhat unrelateable for most people, hence they make a great foil to the hero's mass appeal.
The I and T together are relatively benign. It's the N and J where if misapplied can lead to a skewed world view. But those traits also make for strong leadership (again, good for portrayals of a big bad). I think I stay grounded enough where I don't fall down the rabbit hole like a lot of those villains, the only one from that picture I sort of relate to is Magneto.
You don't see a lot of female INTJs because a lot of their traits are often discouraged in girls by society.
