What percentage of the electorate understands the difference between “accepting” and “believing”?

Question by STFU Dude: What percentage of the electorate understands the difference between “accepting” and “believing”?
Many people, especially Christians, use religious language to describe their positions on scientific theories. For example, they “believe” in intelligent design and consider a “fact” to be a proven “theory”.

This is not, of course, the nomenclature of science. You do not believe in a theory, you “accept” the theory. A theory is not promoted to a fact when it is proven, a theory is a documented hypothesis to explain the facts. Fact: things fall to grown. Theory: gravity.

What percentage of the American electorate fails to understand this basic vocabulary? Is there a correlation with a failure to understand scientific terms and support for intelligent design?
