Well I guess to look at this story with a "glass half full" aspect is that we can say that three-quaters of Americans at least are aware that the earth revolves around the sun. The down side is of course means that 1in 4 Americans'do not know that.
The National Science Foundation asked that question along with 9 others to 2,200 Americans. The average score on the quiz was 6.5. The poll was given in 2012 but the results were released yesterday.
