The Skeptical Inquirer is a bimonthly, American magazine published by the Committee for Skeptical Inquiry (CSI) with the subtitle: "The magazine for science and reason". Founded in 1976 as The Zetetic, it adopted its current name in 1977 after its first editor, marcello truzzi, resigned over the magazine's direction - he wanted advocates of the paranormal to have a permanent presence at the magazine, but lost a vote of confidence.

CSI's mission statement is to "encourage the critical investigation of paranormal and fringe-science claims from a responsible, scientific point of view and disseminate factual information about the results of such inquiries to the scientific community and the public." The Skeptical Inquirer is an international magazine, but is not a formal scientific journal.

As well as addressing paranormal and fortean subjects, the magazine also writes about science and (sometimes) history. Rather refreshingly, it allows a right of reply for anyone it criticises. In 2006 its founder, Paul Kurtz, listed four core policies of the magazine:

  1. to criticize claims of the paranormal and pseudoscience;
  2. to replicate the methods of scientific inquiry and the nature of the scientific outlook;
  3. to seek a balanced view of science in the mass media;
  4. to teach critical thinking in the schools.
