Neanderthals were actually physiologically superior to Homo sapiens. The average Neanderthal was built like Arnold Schwarzeneggar. So, my answer is that when you're pretty enough, you don't need to know anything.
Everyone right of center is right of me, but I'm intelligent enough to know they are not a monolithic social group. This type of prejudice, i.e. stereotyping, is a sign of intellectual sloth, which anecdotal bits of data aside, does not impress.
