No, I don't think so. More likely the question in the survey was poorly worded, and TFA (which I haven't read) was probably as crappy as most non-scientist/statistician summaries of most research.
If the question was "do you believe God created man 10,000 years ago" 46% would be about right. Most people are pretty ignorant about paleontology, jusging from slashdot comments most people don't read enough to know the difference between their there and they're. Personally, I do believe God created it all, but 10k years is far too low; humans have been human for over 50K years and evolved form other apes.
You underestimate the abysmal state of public education in the US, and overestimate the ignorance of article writers. I'd like to see the actual research.
