Confusing belief with fact

I was watching CNN when they had a report about an alleged link between childhood vaccination and autism.  Right after it, they had a poll where they asked the audience if they believed there was such a link.  I found the process disturbing for one reason: whatever I believe may or may not be backed by scientific fact, and in issues such as healthcare this becomes very dangerous.

I might believe that the world is a flat dish, but the facts prove me wrong.
