Raw Story:

Nearly one in five people, or 18 percent, said they think Obama is Muslim, up from the 11 percent who said so in March 2009, according to a poll released Thursday. The proportion who correctly say he is a Christian is down to just 34 percent.

Probing a more universal measure of knowledge, Gallup also asked the following basic science question, which has been used to indicate the level of public knowledge in two European countries in recent years: “As far as you know, does the earth revolve around the sun or does the sun revolve around the earth?” In the new poll, about four out of five Americans (79%) correctly respond that the earth revolves around the sun, while 18% say it is the other way around. These results are comparable to those found in Germany when a similar question was asked there in 1996; in response to that poll, 74% of Germans gave the correct answer, while 16% thought the sun revolved around the earth, and 10% said they didn’t know. When the question was asked in Great Britain that same year, 67% answered correctly, 19% answered incorrectly, and 14% didn’t know.

Bob Harris once provided a slightly more in-depth analysis of similar gobsmacking statistics, but I don’t remember enough details to track down the post. Basically, though, he showed pretty conclusively that no matter what the specific issue, 20-25% of the population can be counted on to be just insanely ignorant, even when it comes to things you thought were utterly beyond debate or misunderstanding. So take a deep breath and relax. One out of every four or five people is eye-poppingly, jaw-droppingly, heart-stoppingly ignorant. ‘Twas ever thus.
