Talking to someone who you think may be lying can be an uncomfortable experience. You may have difficulty focusing on the conversion, instead wondering just how well you can trust them.
Dr. Leanne ten Brinke of the Haas School of Business at the University of California has undertaken recent research that suggests humans have pre-set instincts for detecting liars, however this is often overridden by our conscious minds.
Instead of relying on our underlying instincts, it’s possible to determine whether someone is telling the whole truth by keeping a look out for a few key signs. In fact, research shows that learning about human lie detection can improve your ability to spot deception by up to 90%, which is a high increase when considering most humans are only 54% accurate when spotting lies according to the Science of People.
Ideally, you’ll already have a basic understanding of how the person in question usually acts in social situations. This shouldn’t be a problem if they are a friend or relative whom you regularly interact with. Dr. Lillian Glass, a behavioral analyst who has previously worked with the FBI to determine deception in suspects, suggests that once you understand a person’s normal behavior, it’s easier to pick up on uncharacteristic expressions, body language or attitude to conversation.
You may notice the person make a sudden head movement when asked a direct question, such as a jerk, retraction or tilt. Glass explains in her book, ‘The Body Language of Liars’ that this often happens just before they would usually respond to the question.
