It's absurd but, by and large, people don't actually care about science, let alone understand it. They may occasionally appreciate the rewards of science, but only when it makes them happy. When it sends a negative signal, people are quick to ignore science, or only pay attention to tidbits of science that reinforces their world view. It's not even a question of intelligence. Smart people all the time, including on this very site, fall prey to both anti-science and "scientism" at about the same rate. The only difference between a smart human and a dumb human in this space is the smart human has a bigger vocabulary and knows how to cherry-pick data.

Damore might have been granted some more understanding if he had presented his memo to some scientists. Even then, there would have been a high probability that he would have been told to hush-hush or be asked to leave.
