Many words could be substituted there and any or all could apply. Brainwashed? Naive? There is a well known book that calls it willfully ignorant. As usual, that book prognosticated well. In the 70's I had considered going into education until the dean of education informed me, in a mostly private chat, that the job of a teacher was to get all students to think alike. The whole concept of this was intensely fundamentally flawed to me. Where does invention or new lines of thought, new breakthroughs come from if most think alike? I chose a different field of study with this conversation always keeping me on guard. Today, we see the real world application of this in action carried to its logical and inevitable outcome.
