Midwits and the fairly intelligent are easy to brainwash. Stupid people can be manipulated, with emotion, but they are often stubbornly critical of people trying to manipulate them against their own interests. Smart people rationalize, and once they've consented to "believe" something they've been convinced is good, they refuse to admit they've just been programmed. They're too smart for that, and there's too much of a "house of cards" supporting that position.
