The eyes have it: How to detect deception
If there is a #1 rule in the interpretation of non-verbal human behavior, it is to look for breaks in eye contact
The eyes are the most expressive area of a person’s entire body. In fact, according to Jose Ortega y Gasset, “The eyes are the windows to the soul.”
If there is a #1 rule in the interpretation of non-verbal human behavior, it is to look for breaks in eye contact.
Breaks in eye contact — at the point of the answer — are considered deceptive. Breaks in eye contact indicating deception are generally accompanied by additional deceptive body behavior.
The process of detecting deception, by the use of breaks in eye contact, is used when the investigator is asking a series of questions directed at the subject. In a question-and-answer session, the subject will generally maintain eye contact with the investigator as the investigator is speaking.
You should start with questions that are not relevant to the investigation at hand. Observe the person’s eye contact as you are speaking and they are answering.
This will give you a norm for their behavior — what they normally do. For example:
In this example, the subject maintains good eye contact during the answers.
Normally, a person will maintain eye contact during the question. You are looking for breaks in eye contact when the subject is answering the question. As in our example, the subject maintained eye contact during each answer.
However, a truthful subject will maintain good eye contact while listening and will break eye contact to think or to gather thoughts and reestablish eye contact during the answer.
For example, you ask a subject where they were two nights ago at ten o’clock. The subject will probably break eye contact while they are thinking and mentally gathering the information for the answer.
This should not be considered a deceptive break in eye contact — the person is merely getting the information for the answer. In a truthful response the person, will regain eye contact and deliver the answer.
The deceptive person will not maintain eye contact when they answer the question. They break eye contact, however briefly, while answering the question. After the question is answered, the subject will resume eye contact.
Speaker Question/Answer Subject Behavior
The deceptive break in eye contact occurs at the instance of the answer. These breaks may be subtle, (looking away, blinking, rolling eyes, covering their eyes or diverting their attention to another task as they answer) and coming back to eye contact after the answer.
The break in eye contact is where the subject is mentally running away from you.
In some cultures (and in some people), a subject will not make eye contact at all, constantly looking down or away from you. The above process will not work until the person makes eye contact during the conversation. The techniques to gain their eye contact are not addressed in this article.
Don’t challenge the subject to look you in the eye. This creates false eye contact and obscures your ability to read the true breaks in eye contact.
Another variation of breaking eye contact to gather and deliver information is where the subject is telling a story.
For instance, a subject was assaulted and robbed. While telling the story, the person may not look at the investigator as they are presenting the story. In this instance, the person is replaying the incident in their head and narrating the story as they recall.
During the story, the person may periodically make direct eye contact when a specific point is made. After the story has been delivered, the subject should regain eye contact, waiting for the investigator to respond.
When you are ready to detect deception, I suggest short, simple questions.
For instance: you stop a subject on the street and began talking to him. You may have this conversation.
In this case, you now know the subject has been deceptive and there is a high probability he has marijuana on his person. Where you proceed from here depends on your goals. Your advantage is, you know he has marijuana.
