The Pew Research organization has a 12 question exam to test your scientific acumen.
A survey of 3,278 adults in the U.S. found that, overall, the majority of Americans can answer basic science-related questions, but numbers dwindle as the topic becomes more technical. The researchers found that only 6 percent of respondents got all 12 questions right; eight was the average number of correct answers. If you scored 10 or 11 correctly, you’d be in company with 26 percent of respondents.
