The Independent Investigations Group (IIG) is a volunteer-based organization founded by James Underdown in January 2000 at the Center for Inquiry-West (now Center for Inquiry-Los Angeles) in Hollywood, California. The IIG investigates fringe science, paranormal and extraordinary claims from a rational, scientific viewpoint, and disseminates factual information about such inquiries to the public.
