How about religion? There is a variety of them and they can't all be right (many claim to be the only true one), yet people tend to just believe whichever one they happen to have been raised to believe. They are believing in these massive cosmic arrangements and belief structures...by accident of where they happen to have been raised. And I always have to tell them this.

I expected a very high "obviousness" to my assertion that the median citizen needs to be told these things; that's why I didn't even bother giving evidence. Why is this necessary?
