Originally called the Independent Investigations Group (IIG), the Center for Inquiry Investigations Group was founded in 2000 as the brainchild of Center for Inquiry West Executive Director James Underdown. Underdown’s goal is to “spread a plague of skepticism across the world” by pooling the talents of inquiring minds to investigate wild claims and test those who made them. The CFIIG headquarters are located at the CFI West in Los Angeles.
