Who needs expensive, bulky lie-detector machines?
Liars often give themselves away, without the effort of you hooking them up to a sinister truth-machine or even drugging them, according to an FBI interrogation expert.
Dr. Lillian Glass author of The Body Language, says that certain key signs can be a pointer that someone is speaking with forked tongue – starting off with people who point.
1) They point at you
‘When a liar becomes hostile or defensive, he is attempting to turn the tables on you,’ says Dr Glass.
This can result in a lot of pointing as they attempt to direct the focus back onto you.
2) They cover their mouth
‘A telltale sign of lying is that a person will automatically put their hands over their mouth when they don’t want to deal with an issue or answer a question,’ says Dr Glass.
‘When adults put their hands over their lips, it means they aren’t revealing everything, and they just don’t want to tell the truth.’
2) They cock their head – or jerk it about
If someone cocks or jerks their head when you ask them a question, they may well be lying, says Dr Glass.
Dr Glass says, ‘The head will be retracted or jerked back, bowed down, or cocked or tilted to the side
3) They breathe heavily
People who are lying may breathe more heavily – and you’ll also see their shoulders rise, says Dr Glass.
‘In essence, they are out of breath because their heart rate and blood flow change.
Your body experiences these types of changes when you’re nervous and feeling tense — when you lie.
5) They stop speaking clearly
‘If you ever watch the videotaped interrogation of a suspect who is guilty, you will often observe that it becomes more and more difficult for her to speak,’ Glass writes.
‘This occurs because the automatic nervous system decreases salivary flow during times of stress, which of course dries out the mucous membranes of the mouth.’
