Named for the Committee for the Scientific Investigation of Claims of the Paranormal and its journal The Skeptical Enquirer. CSICOP is a nonprofit educational organization, founded in 1976 to investigate paranormal occult and fringe claims using rigorous scientific methodology. CSICOP has spawned a grassroots movement of some 70 autonomous groups worldwide. Through public education and outreach, CSICOP has become a voice of reason to counter pseudoscience and superstition.
