FactCheck.org on Herman Cain Lie Detector Ad

The non-partisan website FactCheck.org has a well-researched commentary on a new political advertisement in support of GOP presidential candidate Herman Cain that touts his supposed “passing” of a voice stress “test” performed by Atlanta private investigator T.J. Ward. See “Whole Truth About the Cain ‘Lie Detector.'” For additional commentary by AntiPolygraph.org on Ward’s supposed “test,” see “CBS Atlanta Falls for Bogus ‘Lie Detector.'”

Cain Backpedals on Lie Detector, Cites “Layered Voice Analysis”

Republican presidential hopeful Herman Cain has backed off from his declaration at a press conference convened to address allegations of sexual harassment  that he was “absolutely” willing to do a lie detector test. In an interview with Neil Cavuto of Fox News, Cain conditioned his willingness to do a lie detector test on the willingness of an accuser to do so:

Cavuto: …There’s definitely a passion to your fans and your supporters. So, um, why not a lie detector test? You kind of offered for that in your press conference the other day. Um, put it out there, I’m taking a damn lie detector test. I’m gonna pass this with flying colors. Shut up.

Cain: Because, here again, why negotiate against yourself. When somebody comes forward, and they have a claim against me, and *they’re* willing to take a lie detector test, *I’ll* take a lie detector test. I’m not going to go and take one against anonymous, no documentation. That’s not good business…

Cain went on to cite the voice stress analysis performed by private investigator T.J. Ward:

Cain: …And here’s the other thing. There’s a private investigator by the name of T.J. Ward out of Atlanta, Georgia who has some sophisticated technology that a lot of people may not have heard about. He took my statement from my press conference–

Cavuto: I heard that.

Cain: –ran it through his software and was willing to go on record–because many law enforcement agencies use this software–and said, “Herman Cain is telling the truth.”

He did the same thing for this woman who accused me the other day when she was with Gloria Allred, and went through and said, “I’m sorry, but there were a lot of untruths in that statement.”

As AntiPolygraph.org has pointed out earlier, T.J. Ward’s “sophisticated technology”–called “Layered Voice Analysis”–is produced and marketed by a charlatan and has no scientific basis whatsoever.

The Hinterland Gazette points out that private investigator T.J. Ward has previously worked with Cain’s newly hired attorney, Lin Wood, on the Natalee Holloway case, raising the question of whether Ward’s supposed “analysis” was part of an orchestrated public relations campaign.

CBS Atlanta Falls for Bogus Lie Detector

T.J. Ward demos Layered Voice Analysis for CBS Atlanta's Mike Paluska


On Wednesday, 9 November 2011, CBS Atlanta aired an interview with private investigator T.J. Ward, who used a computer program to analyze recorded statements by Republican presidential candidate Herman Cain and Sharon Bialek, who alleges that Cain made a sexual advance on her when she sought his help getting a job. According to Ward’s software, Cain “is being truthful, totally truthful” in denying Bialek’s claim, while Bialek “is fabricating what transpired.”

Ward claimed his software cost $15,000 and has an accuracy rate of 95%. While CBS Atlanta did not disclose the name of this software, a link on Ward’s website indicates that it is Layered Voice Analysis (LVA), a program developed by Amir Liberman’s Nemesysco, Ltd., an Israeli company. This software was completely discredited by Swedish linguists Anders Eriksson and Francisco Lacerda in a 2007 article titled “Charlatanry in Speech Science: A Problem to Be Taken Seriously” (International Journal of Speech, Language and the Law, Vol. 14, No. 2). For more on LVA, see “Nemesysco Founder Amir Liberman Is a Charlatan.”

Not that it matters (LVA being pseudoscientific flapdoodle), but it is perhaps worth observing that private investigator T.J. Ward had chosen the setting for analyzing a male voice when conducting his analysis of Sharon Bialek’s remarks:

CBS Atlanta should have done its homework before running with a “news” story based on emperor’s-new-clothes technology.

Herman Cain Would Absolutely Do a Lie Detector Test

During a press conference convened yesterday to address allegations of sexual harassment, Republican presidential candidate Herman Cain declared that he would “absolutely” be willing to take a lie detector test, though he quickly added, “but I’m not going to do that unless I have a good reason to do that.”

Cain’s declaration came in response to the first question asked during the press conference, which was posed by CBS News West Coast correspondent Steve Futterman. It is disconcerting that a “serious” journalist would ask such a frivolous question (lie detector “testing” has no scientific basis), but it is emblematic of the mythical status of the polygraph in American pop culture.

Because the myth of the lie detector is so deeply entrenched in the American psyche, it would have been very difficult for Cain to have rejected the suggestion of a lie detector test and pointed out its unreliability. Instead, Cain went on to add that he had discussed his willingness to take a lie detector with his staff and with his attorney, who evidently failed to dissuade him from such foolishness.

If Cain does submit to a polygraph test, it is likely to be arranged by his lawyer under terms of attorney-client privilege. If Cain doesn’t pass, the public will never hear about it, and his lawyer can have him polygraphed by someone else until he does pass. Then his lawyer can announce to the world that Cain has passed a polygraph denying the sexual harassment allegations against him.

Apart from the fact that only the result of a passed polygraph will be made public, it’s worth noting that while polygraphy is inherently biased against the truthful, liars can pass the “test” using simple countermeasures that polygraph operators have no demonstrated ability to detect. For an in-depth explanation of how to pass a polygraph whether or not one is telling the truth, see AntiPolygraph.org’s free book, The Lie Behind the Lie Detector.

The following is the portion of Herman Cain’s press conference that dealt with the lie detector (transcription by AntiPolygraph.org):

Steve Futterman: Mr. Cain, Steve Futterman with CBS News. I’d like to ask you a two-part question. First of all, do you think it is appropriate for a candidate’s character to come under a microscope in a campaign? And secondly, you are basically now in a he said/she said situation. She’s saying something; you’re saying something. They’re both diametrically opposing each other. As distasteful as it might be, would you be willing to do a lie detector test to prove your honesty in something like this–

Herman Cain: Yes–

Futterman: Sure, go ahead…

Cain: Yes, I absolutely would, but I’m not going to do that unless I have a good reason to do that. I have, look, that was one of the first comments I made in watching this to my staff. I’ve also shared that with my attorney. Of course I would be willing to do a lie detector test. Secondly, I believe that the character and integrity of a candidate running for president should come under a microscope: with facts, not accusations.
