Can You Cut It as a Human Lie Detector?
By Jake Taylor, Marketing –

While a liar usually doesn’t cross their fingers, there may be other physical cues to detect if someone is lying.
There are some people that claim to be a human lie detector. They claim that they are able to read body and speech cues given by those who are lying and, with that information, determine the subject’s level of integrity.
When I researched this issue, I wondered exactly what kinds of things should one look for when determining a person’s honesty.
The Cues of Deception
Body positioning might indicate a person’s intentions. Usually a person who is trying to conceal the truth will move in some irregular fashion. Sometimes this manifests as a twitch, shrinking to one side or crossing the arms or legs. Also, by touching the person’s hands, you can see if they’re sweating. Sweating is usually a telltale sign of lying.
Specific speech patterns can give away deceit as well. Heavy sarcasm may be used to conceal the truth. Mocking tones and repetition of the question can also give away a liar. Someone telling the truth isn’t going to say, “No, I did not go out and party last night.” They’ll usually just say no.
According to human lie detectors, the biggest give away about a person’s integrity is the eyes. Flitting eye movement, a lack of eye contact and looking down often give away a person’s true answer. Even in my own experience, when a person won’t make eye contact with me, I feel that they are hiding something.
Going With Your Gut
All of these techniques depend on how the subject is feeling and how keen the interviewer’s intuition is; both are very subjective and often inaccurate. In my own experience, I have discovered that intuition regarding anything comes after long hours of study and association. While you might not be actively studying the people with whom you associate, you get to know their mannerisms quite well over time.
This is how I believe intuition works for someone like a mother or a spouse; for those of us who don’t know our subjects that well, a more accurate honesty test is needed.
Hard Data
A person’s feelings are only worth so much in the eyes of society. We tend to value hard data much more than qualitative, and for good reason. Feeling like someone is lying to you is much less accurate than a lie detector test. In fact, only 54 percent of intuition and observation testing is correct in determining honesty. (Bond & DePaulo, 2006.)
For decades, the polygraph has been the most accurate qualitative method for determining honesty. This method depends a great deal on the emotional state of the interviewee and the skill and questions of the interviewer, which has left people searching for a more reliable method.
Luckily, a new solution on the truth verification market has arisen — EyeDetect®. This system accurately and effectively produces hard data regarding a person’s integrity, data that is invaluable in a professional setting. The system tracks involuntary eye movements while interviewee answer true/false questions on a computer screen. It takes emotion and skill out of the process and gives results with 85 percent accuracy. When intuition won’t cut it, EyeDetect is a worthwhile option to consider.
