How important are nonverbal clues to detecting deception?
What are some nonverbal cues to deception? Psychological folklore tells us that it is. Studies on what people believe about lying and deceit identify a number of non-verbal cues associated with lying (Vrij, 2000, 2008; The Global Deception Research Team, 2006)—gaze avoidance, fidgeting, restless foot and leg movements, frequent body posture changes.

Is flipping a coin the best way to detect deception?
Jan 16, 2018 · This survey found that most participants discovered lies through verbal cues or hard evidence, rather than noting tone, eye contact, or other nonverbal cues.

Why is it important to pick up on subtle nonverbal cues?
Instead of simply focusing on hard evidence, it is important to pick up on subtle nonverbal cues in order to begin to learn when we are lied to. While we all have some ability to do this, it is also something that you can improve on, like all efforts to read people.
Why is reading nonverbal behavior important?
A recent 2017 study argues that reading nonverbal behavior is a crucial component to discovering mistruth and understanding if another person is lying. In this research, Dr. Eric Novotny and a team of scholars respond to previous research that underplays the role of nonverbal clues in everyday deception detection.
Is finding a lie different from beginning to suspect one?
Novotny and his fellow researchers concluded that discovering a lie is quite different from beginning to suspect one.
Do liars have special motivation?
In many studies , the liars did not have any special motivation to tell a convincing lie. Many simply participated as part of a study, with no special rewards for succeeding or punishments for failing. It is of importance to separate those studies in which participants had some special motivation to do well and those in which they did not. The question is this: If people are motivated to get away with their lies, will that show up in the form of fewer cues to deception because they are trying harder to tell a good lie or will their lies become more obvious as the stakes are raised?
Do nonverbal cues correlate with truthfulness?
The most notable result of research to date is that nonverbal behaviors generally do not correlate strong ly with either deception or truthfulness; very few reliable nonverbal cues to deception have been found.
Do liars have shorter response times than truth tellers?
Sometimes suspects know beforehand that they are going to be interviewed, which gives them a chance to prepare their answers. Presumably, liars should manage to appear more like truth tellers when they can plan their answers in advance than when they cannot. The available research indicates that when having time to plan, liars have shorter response latency than truth tellers. When there is no time to prepare, the opposite pattern is found. There is also some evidence that liars show shorter message duration than truth tellers when they have time to prepare their responses.
What does it mean when a subject is dishonest?
Similarly, a subject who is being dishonest might actually arrange his or her body in a position that suggests fleeing the room. While the person’s upper body is facing the interviewer, his or her legs may be facing the door, as if in an unconscious effort to leave.

What should be the rules for setting up an investigation room?
When setting up a room for conducting an investigation interview, there are a few basic rules the investigator should keep in mind.

This means that there should be no physical barriers between the interviewee and subject that might block the interviewer’s view of the subject.
What does it mean when someone is not stressed?
One thing to keep in mind is that non-verbal clues mean nothing in isolation. Some people exhibit these characteristics when they are not stressed, and some people are stressed all the time, whether they are being deceptive or not. So it’s important for investigators to treat clues as insight into where to probe further, rather than as proof of deception.
Why do investigators keep furniture out of the way?
Another reason to keep furniture out of the way is to provide the investigators with a full-body view of the subject. This is important when assessing the subject’s body language , or non-verbal clues, when he or she is answering questions and providing detail about the incident in question.
What is an illustrator?
These are hand motions a person makes when talking. They are normal and often used to illustrate a point.

A change in the use of illustrators, therefore, may be taken as a possible clue to deception.

Scientific Study of Nonverbal Behaviors
- To find out about potential nonverbal correlates of deception, psychologists and other researchers conduct experiments. They instruct some people to lie and/or tell the truth (the lies are most often “constructed” for the sake of the experiment) and videotape the telling of truths and lies in interviews or mock interrogations. (If the focus is on the speech-related variables, au…
Theoretical Approaches
- Why would the nonverbal behavior of a liar give him or her away? Scientists usually suggest three different processes (or approaches) that might answer that question. According to the emotional approach (sometimes called the affective approach), the three most common types of emotion associated with deception are guilt, fear, and excitement. A liar might feel guilty because he or s…
Nonverbal Behavior and Deception in General
- The most notable result of research to date is that nonverbal behaviors generally do not correlate strongly with either deception or truthfulness; very few reliable nonverbal cues to deception have been found. There is evidence that liars tend to speak in a higher-pitched voice, which might be the result of experienced arousal. However, differences in pitch between liars and truth tellers ar…
Transgressions
- An important factor, and most relevant to the forensic context, is the distinction between lies that are about transgressions and those that are not.

In other studies, participants, for example, pretended to experience another emotion that they did not in f…

Limitations and Conclusions
- Although researchers have in some studies tried to raise the motivation of and the stakes for the lying participants, the question still remains how the results from laboratory-based studies reflect what may happen in real-life high-stakes situations such as police interviews. In a few studies, the behavior of real-life suspects, interviewed about serious crimes such as murder, rape, and arson …
