There's an ingrained distrust in our society of highly intelligent, highly trained, highly competent persons. One need only look at the last presidential election for proof of that.

Man has one name, and many more than two natures. But the essential two are these: that he shall strive to impose order on chaos, and that he shall strive to take advantage of chaos… A third element of man’s nature is this: that he shall not understand what he is doing.

We know a lot nowadays about how to extrapolate from rats to people, but we don't only have to rely on that. In a sense we've made ourselves into experimental animals. There are too many of us, too crowded, in an environment we've poisoned with our own-uh-byproducts. Now when this happens to a wild species, or to rats in a lab, the next generation turns out weaker and slower and more timid. This is a defense mechanism.
