Enlightenment Now: The Case for Reason, Science, Humanism, and Progress

by Steven Pinker

Professing a belief in evolution is not a gift of scientific literacy, but an affirmation of loyalty to a liberal secular subculture as opposed to a conservative religious one. In 2010 the National Science Foundation dropped the following item from its test of scientific literacy: “Human beings, as we know them today, developed from earlier species of animals.” The reason for that change was not, as scientists howled, because the NSF had given in to creationist pressure to bowdlerize evolution from the scientific canon. It was that the correlation between performance on that item and on every other item on the test (such as “An electron is smaller than an atom” and “Antibiotics kill viruses”) was so low that it was taking up space in the test that could go to more diagnostic items. The item, in other words, was effectively a test of religiosity rather than scientific literacy.
