One in four Americans doesn’t know that Earth revolves around the sun. Really. That was one of the more staggering findings of the National Science Foundation’s biennial survey of Americans, part of a larger report recently released to Congress last year on the state of science in the United States.
In the 2014 survey of more than 2,200 Americans, respondents answered just 65 percent correctly on average. (That would be a D in most junior high or high school science classes…)
Those who had completed bachelor’s degrees answered 78 percent of the questions correctly, only 45 percent of high school grads did, and people over 65 also scored lower than younger people.
