Darren Stanton is a former police officer who is now the UK's leading human lie detector and body expert.
He joins us to discuss his skills on how to guess the truth and provide examples of the signs that liars always give away!
How to spot a liar
Here are Darren's top tips for spotting someone who is being economical with the truth:
People might clutch a clipboard/file or coffee cup to their chest, creating a subconscious barrier if they're lying or holding it in two hands
Statistically it's a myth that a liar can't look you in the eye. Three to five seconds of eye contact is normal. Any longer and they are either in love with you or fibbing.
Liars don't like being asked for details. If they're not prepared, they'll either mirror your language or stutter for an answer. Just minor details can trip up a liar.
The greater the consequences, the more signals a liar gives off. For example, a person who has committed a serious fraud would give more signals than someone who has stolen your cream cake out of the fridge at work.
Many readers will say they already have the ability to know when their children or partner is lying and this can be true. The difference is that the techniques I've learned accelerate this process so I can have the same level of rapport and insight with another in seconds
There are many verbal cues that can suggest someone is lying, including;
Slowing down breathing
Becoming less animated
Over compensating with eye contact
Blink rate may double and triple
Liars often twitch when they are being untruthful. If recognised this can be one of the easiest giveaways to identify.
Sometimes it can be a particularly long blink, or it could be a tiny muscle in the cheek or neck. Men in particular have an area at the bottom of their nose that twitches when they are fibbing.
