Why is this popular belief not true? From feeling shy to simply thinking about an answer, there are many reasons we avoid eye contact. Eyes can give clues to a person’s feelings, such as fear or pleasure, but they don’t tell us what caused those feelings.1 Alone, they cannot tell us that a person is lying. To determine the cause of a person’s feelings requires multiple clues that come from other body language, context, situational information, etc. This is especially true for detecting lies.
Knowing this can prevent the mistake of thinking a person is lying simply because they don’t “look you in the eye”. It’s also useful to know that because most of people believe liars avoid eye contact, a liar might look you in the eye to appear more truthful.2
The evidence supporting this has been public for years. I learned about it in 1984. More than twenty-five years later, it isn’t surprising that lack of eye contact is still one of the most popular beliefs about lying.3 It’s perpetuated in erroneous magazine articles and blogs about how to catch liars and cheating spouses.
I mentioned that mistaking the truth for a lie can lead to tragic consequences. Consider how it can damage relationships with colleagues, friends and family. How does it effect jurors when deliberating a person’s guilt? See Wrongfully Convicted (humintell.com) for the disturbing answer. 4
“Does blinking excessively, avoiding eye contact, or looking in a particular direction show a person is lying?
Not necessarily, said David Livingstone Smith, associate professor of philosophy at the University of New England and author of 2007’s “Why We Lie.””
