What’s your Health IQ? Take this test to find out!

According to a recent article in the Los Angeles Times, American adults get a “D” in science; 22% confuse astronomy and astrology! On a general science knowledge quiz consisting of 12 questions, the test-takers answered 7.9 correctly, on average. That’s a score of 66%. Only 6% answered all 12 questions correctly.

Similarly, lack of health literacy is also a huge problem among Americans. We are continually bombarded with often-contradictory health information. U.S. patients are confronted with  myriad treatment options they are ill-equipped to properly choose among. Urban legend, aggressive direct-to-consumer advertising, and dumbed-down media stories add to the confusion.
