IIG meaning in Governmental ?

The Center for Inquiry Investigations Group (CFIIG), formerly the Independent Investigations Group (IIG), is the largest paranormal investigation group in the world, with allied groups and field investigators in the United States, Canada, the UK, Italy, Australia, South Africa, and Germany. It investigates fringe science, paranormal and extraordinary claims from a rational, scientific viewpoint, and disseminates factual information about such inquiries to the public, and offers a $250,000 prize to anyone who can "prove paranormal ability, under scientific testing conditions".: 43:15 

While the CFIIG conducts scientifically based experiments, its membership is composed primarily of lay-people. Members' collective professional experience includes the fields of architecture, archeology, education, electronics, engineering, film making, law enforcement, medicine, psychology, and visual effects.

James Underdown founded the volunteer-based organization in January 2000 at the Center for Inquiry-West (now Center for Inquiry – Los Angeles) in Hollywood, California, and acts as its executive director.
