Can you tell if a person is lying by their eye movements?

There is a popular belief that a person's eye movements can reveal whether they are lying or telling the truth. However, scientific research has shown that this is a myth and that there is no reliable correlation between eye movements and lying.

The idea that certain eye movements are associated with lying comes from the theory of neuro-linguistic programming (NLP), a discredited pseudoscientific approach to communication and personal development. NLP claims that when people lie, they look up to the right, while truthful answers are accompanied by looking up to the left. However, numerous studies have failed to find any evidence to support this claim.

While eye movements can provide information about a person's mental processes and cognitive strategies, they cannot be used as a reliable indicator of lying. Instead, experts suggest looking for other signs of lying, such as inconsistencies in their story, changes in their behavior, and physiological changes such as increased heart rate or sweating.
