15 Miss USA contestants demonstrate that they don’t know enough to know that they don’t know enough. In other words, these beautiful contestants are beautifully demonstrating the Dunning-Kruger cognitive effect:
The proper answer from each of these contestants should have been “I can’t answer that question, because I don’t understand the scientific theory of evolution. Maybe I should go read a few good books, on evolution. Then I’ll let you know whether I am competent to answer that question.” To answer like this, though, is not the American way. When you are prepared with make-up and the cameras come on, you tend to wing it in such a way to please the majority of your audience. This is what beauty contestants and politicians have in common.
