The Committee for Skeptical Inquiry (CSI), formerly known as the Committee for the Scientific Investigation of Claims of the Paranormal (CSICOP), is a program within the U.S. non-profit organization Center for Inquiry (CFI), which seeks to "promote scientific inquiry, critical investigation, and the use of reason in examining controversial and extraordinary claims." Paul Kurtz proposed the establishment of CSICOP in 1976 as an independent non-profit organization, to counter what he regarded as an uncritical acceptance of, and support for, paranormal claims by both the media and society in general. Its philosophical position is one of scientific skepticism. CSI's fellows have included notable scientists, Nobel laureates, philosophers, psychologists, educators, and authors. It is headquartered in Amherst, New York.
