Center for Inquiry Investigations Group
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
|Type||Non-profit educational organization|
|Headquarters||CFIIG LA, Hollywood, California, with one affiliate: CFIIG San Francisco Bay area|
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.
High profile investigationsEdit
Power Balance braceletsEdit
On October 28, 2010, Olympic Champion Gymnast Dominique Dawes, working for Yahoo Weekend News and with the Independent Investigations Group, tested Power Balance bracelets for their claim that they improve balance, flexibility and strength. She states, "The fact is, all athletes know that nothing can replace good old-fashioned hard work—practice, practice, practice...Can a silicone wristband with a hologram sticker really give you an added edge?" According to IIG investigator Dave Richards, "There was one 'legitimate' Power Balance bracelet, and 3 'sham' bracelets that had had the hologram removed from them. The experiment was double-blinded, all bracelets were wrapped with tape so no one present knew which bracelet was real and which were fakes." One of the control bracelets contained PEZ candy. "Neither the participants nor the people recording the scores knew which bracelet was which until after all participants had completed their runs and their scores were recorded." From Wendy Hughes' report, "The claim was that if the hologram worked, the speed of the participants would increase, and it would show on the graph. But it didn't. Out of 64 heats, 16 participants using 4 bracelets in 4 random heats, the results were almost flat. The main result was that if there was any change, the familiarity with the course caused a slight increase in efficiency. The Pez didn't make a difference either." Dawes' conclusion is that superstition makes the Power Balance bracelets seem to work.
On November 21, 2009, the IIG administered a preliminary demonstration for IIG Paranormal Challenge applicant Anita Ikonen. The demonstration consisted of three trials, wherein Ikonen was faced with six people who were sitting away from her, and whose faces were obscured. In each of the three trials, one person was known to be missing a kidney. That meant that of 12 possible kidneys, one was missing. Ikonen had to determine which kidney was missing. On her sheet, she was to mark which kidney was missing (right or left) on the diagram of the person corresponding to the kidney. She had to choose correctly on all three trials in order to succeed, and move on to a formal test which, if she was successful, would earn her $50,000. Ikonen did not succeed. She chose incorrectly on trial one, chose correctly on trial two, and chose incorrectly on trial three. She failed the Preliminary Demonstration and this failure falsified her claim to be able to see inside of the human body and accurately determine if a person is missing a kidney or not.
Electric mind controlEdit
IIG tested an applicant who claimed to be able to "influence electricity with [his] mind." and control the intensity of a light bulb. The subject was placed in a darkroom with a frosted-glass incandescent light bulb mounted on a tripod, and a light meter was pointed at a large white board mounted behind the bulb. The subject was not allowed to touch or approach the apparatus. The agreed-upon threshold for a successful test was to achieve ten out of fifteen trials in which the subject had two minutes to vary the meter reading either up or down by 3 exposure value (EV) settings. During the first six trials, the light meter failed to move more than 0.1EV, after which the test was terminated. Afterwards, the subject explained that "Whenever I'm just, like, driving around [...] when there's a light, like, flickering [...] just focus on it, and it just happens". The IIG concluded that "There is no evidence from this demonstration that Subject possesses psychic ability."
The Independent Investigative Group looked into 14 cases Carla Baron claims to have assisted detectives on, including JonBenét Ramsey, Elizabeth Smart and Nicole Brown Simpson. In all 14 cases the IIG contacted the police (or in the case of Nicole Simpson, they received an email from Denise Brown) all mostly saying the same things, "we have never heard of this person" or "the information provided (by Baron) did not produce any new leads in the investigation". IIG's conclusion is that she has never provided any help in any investigation, and her claims stating such are unsubstantiated.
In 2003 the IIG attended a taping of James Van Praagh's syndicated series Beyond, in order to document the difference between what actually occurred at the taping and how it appeared on TV after editing. As suspected, there were many significant differences, and the IIG concluded that Van Praagh’s power emanates from the editing room."
IIG tested Sparky the "wonder dog" and deduced that the dog was reacting to movements from his owner Gordie Rosenberg and not to telepathy as was claimed. Also discussed in this article by newspaper New Times Los Angeles, Inc. are tests of Mark Joramo and his telekinesis foil flap device (failed test, air movement from Joramo's hand made the flap move) and dowser Frank Mashenko (failed test, ideomotor effect).
The CFIIG offers $250,000 to anyone who can demonstrate paranormal abilities. The CFIIG is involved in designing the test protocol, approving the conditions under which a test will take place, and in administering the actual test . The CFIIG is involved in designing the test protocol, approving the conditions under which a test will take place, and in administering the actual test. All tests are designed with the participation and approval of the applicant.
When CFIIG first began the challenge, they expected a deluge of applications from people trying to win using deception. In most cases, the applicant is asked to perform a simple preliminary demonstration of the claimed ability, which if successful is followed by the formal test. Associates of the CFIIG usually conduct both tests and preliminary demonstrations at their location in Hollywood or affiliates.
Many people have unsuccessfully attempted to win the prize. Of the 100 to 150 applications received by CGIIG, only a handful make it to the testing phase. Most won’t agree to the proposed testing criteria or they stop responding to emails asking about the details of their talents.
The Center receives applications from all over the world and applicants make all kinds of claims. James Underdown says they all have one thing in common: they sincerely believe they possess abilities that science can’t explain. “One hundred percent of the people we’ve tested completely believe in their own ability.”
The IIG AwardsEdit
In 2005, the IIG created an annual "awards program to recognize the promotion of Scientific and Critical Thinking in mainstream entertainment." The membership selects by vote the media programs from the previous year that are the "best and worst examples of scientific and critical thinking." The good award winners are "affectionately referred to as the 'Iggies'." The program(s) voted the worst are called 'The Truly Terrible Television' winners. Its counterpart in the movie category is given the 'Mostly Miserable Movie certificate'.
In conjunction with the media awards, an inductee is selected for the "Houdini Hall of Honor" award for "substantial career devotion". Named in honor of Harry Houdini who is considered a role-model to the CFIIG as a paranormal investigator who educated his audience through the media. All honorees are listed on a plaque that is displayed at the Steve Allen Theater. The first award ceremony happened in 2007 for media released in 2006, all presentations have been open to the public, the MC has been the chair and founder of the IIG, James Underdown. All have taken place at the Steve Allen Theater in Hollywood.
Iggie award winnersEdit

Music provided by Gary Stockdale with Scott Breadman. In his recorded acceptance speech Minchin stated that he was honored but felt "rather silly, because you are the people that write all the information and material that I steal and repackage it using rhymes and feed it back to you, to my financial and personal gain. And you give me an award as well. That's almost like I'm running a scam here." Penny Chan from The Skeptic Zone interviews Jim Turner, Mark Edward and musician Gary Stockdale.
Truly Terrible Television (TTTV) award winnersEdit
Regarding the TTTV awards, Neil deGrasse Tyson stated that he is "glad that you are giving the dubious pseudoscience awards, somebody has to call this stuff out. I sure as hell don't have the time or patience to reason someone out of a point of view that reason itself was never invoked to acquire."
In 2007, the Truly Terrible Television Awards were given to Court TV's Psychic Detectives, and to the Montel Williams show for every episode featuring Sylvia Browne. In 2008 The Truly Terrible Television Award was presented to Paranormal State (A&E) and Ghost Hunters (Syfy).
Houdini Hall of Honor AwardEdit
Lifetime achievement awards went posthumously to Harry Houdini (Erik Weisz) and Carl Sagan. Ann Druyan sent a letter acknowledging the recognition and thanked IIG for the lifetime achievement award presented to Carl Sagan.
James Randi was honored for exceptional ongoing achievement by his induction into the "Houdini Hall of Honor" in 2008. Presenters Julia Sweeney, Dean Cameron and comedian Paul Provenza were also in attendance.
