There’s lots to delve into in Jon Miller’s study of civic scientific literacy, not least that US student jump from poor science performance in high school to high science literacy as adults thanks largely to the mandatory year-long science course most colleges require.
More important, perhaps, is the fact that (using path analyses controlling for age, education, and other relevant social variables) TV viewership has a negative effect on science literacy, while print media consumption has a small positive effect and internet usage has a substantial positive effect. Could this be thanks to 4chan?
Note also that religious fundamentalism/religious activity has no impact on scientific literacy outside the U.S. and Spain. Britain and Germany certainly have religious fundamentalists, but it doesn’t influence science literacy of adherents. Dunno why, but I’ll ask Miller.
