As anti-vaccinationists, global-warming denialists, and young-earth creationists know, it’s not too hard to fool the public with bogus science. But a new exercise by John Bohannon of Science suggests it’s not too hard too fool professionals either. Bohannon used a computer program to generate unique iterations of a purposely flawed paper, playing Mad Libs with the formula “Molecule X from lichen species Y inhibits the growth of cancer cell Z.” He sent his fake papers to 304 open-access journals, and it was accepted by more than half.
