When a person in front of you tells something while regularly looking away, the reflex is often the same: suspecting a lie. However, non-verbal language specialists point out that in conversation, we only maintain direct eye contact about 40 to 60% of the time. The rest, our gaze wanders, rests on the table, on a wall, on our hands. This back and forth is part of the normal functioning of the brain, far from automatically being a sign that we are trying to hide the truth.
Psychologists explain that looking away when speaking much more often reflects a lack of self-confidence than an intention to deceive. Psychologist Paula Martínez, specialist in cognitive neuroscience, sees it as the reaction of a person who feels threatened, insecure or embarrassed. Much research in experimental psychology also indicates that no eye direction can reliably detect lying. A liar may hold your gaze, while a sincere person may shy away from it simply because they feel judged.
Looking away while speaking: a normal gesture for the brain
In a conversation, the look is used to capture attention, but also to give rhythm to speaking turns. When someone stares at you and then goes silent, they are often waiting for your response. Studies on nonverbal communication believe that a fluid exchange alternates eye contact and pauses, which gives the brain time to search for memories, choose words or manage rising emotion.
When a task becomes difficult, many people spontaneously look elsewhere to concentrate. This movement, observed in psychological research, appears in both children and adults. It is added to other gaze signals, such as narrowed eyes in a defensive position or rapid blinks linked to nervousness.
Shifting gaze: lack of self-confidence, fear of judgment and context
For psychology, a shifty gaze very often refers to inner insecurity. Not looking at the other person’s eyes allows you to protect yourself from feared judgment, to hide shame or the fear of saying something stupid. For some people, each exchange is experienced as a mini exam; looking away then becomes a discreet but constant armor.
This lack of confidence is often combined with shyness or greater social anxiety, especially during an interview, an argument or a difficult confession. The cultural context also matters: in several Asian countries, fixing a superior can be perceived as aggressive. Some people with autism or ADHD even find eye contact sensory exhausting.
Why looking away while speaking doesn’t prove a lie
Popular theories have claimed that looking left or right betrays a lie or memory. Psychology research has not confirmed these patterns: no solid study shows that a simple eye movement is enough to spot a dishonest person.
Before accusing someone who avoids your gaze of lying, it is best to observe the tone of their voice, the coherence of their story and their stress level. Creating a softer setting, accepting silences or placing themselves side by side can already help them feel more secure.
