The public is an ass

Via the Economist's "Democracy in America" blog, these poll figures:

Percentage of Americans who believe in angels: 55

Percentage of Americans who believe in evolution: 39

Percentage of Americans who believe in anthropogenic global warming: 36

Percentage of Americans who believe in ghosts: 34

Percentage of Americans who believe in UFOs: 34

I wish they'd asked about the sum of a triangle's angles, while they were at it.
