Who developed the polio vaccine? Does water boil at different temperatures based on altitude? Which is the hottest of Earth’s three layers? Take our science quiz and see how you compare with Americans overall.
The American Trends Panel (ATP), created by Pew Research Center, is a nationally representative panel of randomly selected U.S. adults living in households. Respondents who self-identify as internet users (representing 89% of U.S. adults) participate in the panel via monthly self-administered Web surveys, and those who do not use the internet participate via telephone or […]
This report examines the general public’s knowledge about 12 science-related topics. The data were collected on the Pew Research Center’s American Trends Panel. This report also includes a series of tables with findings from the new Pew Research survey and from previous Pew Research studies on science knowledge to allow for comparisons across a wider […]
The set of 12 questions from the new Pew Research Center survey is, of course, only a small fraction of the possible topics and approaches to measuring public knowledge and understanding about science. In this section, we show the 12 questions from the new survey alongside other science knowledge questions asked across a handful of […]
People’s science knowledge sometimes varies by age, race and ethnicity, though the patterns are far from uniform across this set of 12 questions in the new Pew Research survey. On some questions, younger adults tend to know more than their elders (such as which kind of waves underlie cellphone calls). But that pattern is reversed […]
Men tend to answer more of these science knowledge questions correctly than do women, the new Pew Research Center survey found. Men score an average of 8.6 out of 12 correct answers, compared with women’s 7.3 correct answers. Some 24% of women answer 10 or more questions correctly, compared with 43% of men who did […]
In the new Pew Research Center survey, more-educated Americans generally score better overall in answering science-related questions than those who have a high school degree or less. And those with a college degree or higher tend to perform better on the toughest questions. Adults with a college or postgraduate degree are more than twice as […]
