John Legend and Chrissy Teigen Agree to be Polygraphed

“Are you waiting for me to lose the baby fat?” and “Would you have married me without a prenup?” are just a few examples of the questions asked…
By Eliza Sanders, Marketing —
In a recent Vanity Fair video, Chrissy Teigen and John Legend sit down to ask each other the hard questions. To raise the stakes, they agreed to hook themselves up to a polygraph machine.
To begin, John asked Chrissy a whole array of questions: Has she ever been embarrassed by him? Does she listen to his music when he’s not there?
“Yes,” Chrissy replies quickly.
“That is true,” the polygrapher affirms.
Chrissy is quick to return the favor with questions like “Are you waiting for me to lose the baby fat?” and “Would you have married me without a prenup?”
To the former, John replies without hesitation that no, he thinks she’s perfect the way she is. To the latter, he teases that if he’d known she’d be so successful, he might’ve written their prenup differently.

While it is quite fun to see this celebrity couple poke fun and be playfully vulnerable with each other, I must point out the inaccuracy of this situation.
First, all the sensors they are both connected to measure different things. The one across the upper chest reads respiration patterns. The blood pressure cuff on the bicep takes blood pressure readings; and sensors on the fingers monitor pulse and sweat.
Right away we can see that one of these was not operational during their tests and that was the blood pressure cuff, which would have to be inflated in order to be gathering data. Clearly, it was not.
A typical polygraph also consists of no more than three relevant issues asked more than one time. In order to gather enough data to determine credibility, a polygrapher will need to analyze multiple responses to the same question. They will ask a question about every 30 seconds, to give space between to make sure responses can be isolated to one question, and not to other ones. They will also make sure to ask questions that only require a “yes” or “no” response, as anything more than that will create too much movement and breathing.
Chrissy and John asked quickly and successively many queries that were not repetitive or with very much interlude between. A lot of the time their answers were not yes or no, but were lengthy and only semi-conclusive. They both moved a lot while replying, shifting in the chair and gesturing with their hands for more lengthy responses. All of that would make it impossible to decipher their readouts for their questions.
Therefore, this exchange, though cute, can’t really be all that valid.
EyeDetect is a computerized lie detector that uses an eye tracker to measure involuntary responses in the eyes. When you lie, the eyes react- they never lie.
EyeDetect tests require an examinee to be seated in front of a computer while they respond to True or False question by clicking a mouse. There is no correspondence between proctor and test-taker, and it is scored using a computer algorithm, minimizing errors that occur through human bias.
EyeDetect is fast, lasting about 15-30 minutes. Without the need to wait between questions to isolate responses, the test can query on relevant issues more times, receiving more data and increasing the accuracy overall.
EyeDetect can be used to test people accused of murder, assault, infidelity, previous work-place discipline and many other illegal or inappropriate activities.
While I do not trust the validity of Chrissy and John’s polygraph, I’m inclined to read in their eyes genuine feeling for each other. I wonder if the computer would agree…
