Often a sign of expertise is noticing what doesn't happen. - Malcolm Gladwell

Our unconscious thinking is, in one critical respect, no different from our conscious thinking: in both, we are able to develop our rapid decision making with training and experience.

In teaching, the implications are even more profound. They suggest that we shouldn’t be raising standards. We should be lowering them, because there is no point in raising standards if standards don’t track with what we care about. Teaching should be open to anyone with a pulse and a college degree — and teachers should be judged after they have started their jobs, not before.

Defaulting to truth is a problem. It lets spies and con artists roam free.
