Test if You Know What You Don't Know

One of my favorite quotes is due to the American humorist Josh Billings (Henry Wheeler Shaw):

"I honestly beleave it iz better tew know nothing than two know what ain't so."

Sometimes this is reported as:

"It's not what you don't know that scares me; it's what you know for sure that just ain't so."

Now here's a little test that claims to identify your "risk intelligence quotient": not what you know, but how accurate your estimates are of what you do know.

I'd love to see the blustering creationists Denyse O'Leary and Kirk Durston take this test. My guess is, they wouldn't score very high.

So take it, and leave your score in the comments.
