I think a lot of Ns and sociopaths are not conventionally 'book smart', but they are cunning, the way that animals who will die without preying on smaller animals are cunning. These people often have a 'sense' of who's a danger to them, and who they can prey on; and they'll skirt the former and pounce on the latter. When the prey has the audacity to turn on them (by saying 'no' or by walking away or cutting them off), they're baffled and enraged.
