Secret Service agent reveals how to know someone is lying to you just by listening to their voice

A veteran Secret Service agent who protected the president has revealed the easy way to instantly know someone is lying to you.Brad Beeler, an expert in interviews, interrogations and lie detector tests, said deception was easier to spot by focusing on someone's wording and delivery than looking for clues in their body language.Beeler explained that the truth should roll off the tongue smoothly like a movie reel. The person speaking should be able to rewind it, fast-forward it and 'hit play' again naturally – something that does not happen when a story is made up.'The problem is on a manufactured story, people have a hard time rewinding and fast forwarding, thinking about what the smells were, what their feelings were because it's a created situation,' Beeler explained.He also came up with a simple system that can spot red flags in someone's story, which was aptly named LIARS.It stands for Latency, a long pause before answering, Incongruence, when words do not match someone's tone or body language, and Avoidance, someone dodging the real question with words such as 'normally' or 'usually.'The final parts in Beeler's system are Resistance, when the liar gets offended and turns the question back on you and Shifting vocal inflection, when the tone of the answer rises and almost sounds like a question, such as 'Yes?'He also debunked several myths about telling lies, claiming that body language actually a bad way of weeding out false statements and noting that liars often make better eye contact than people telling the truth.

Bush.He worked for nearly 17 years as a polygraph examiner, conducting more criminal lie detector tests than any other agent in the Secret Service's history.From his experience arresting suspected criminals, Beeler said that people will tell you the truth quickly if you avoid the appearance that you are judging their answers – even if they have just committed a serious crime.'I just would take the time to listen to people. And that’s when I learned if you let people teach you and you don’t judge them, they will tell you everything. Everything. They really will,' he said during an interview with LADbible released on October 25.Despite his record-setting experience with lie detector machines, Beeler said polygraphs do not actually detect lies.Instead, they measure stress, looking at factors such as a person's heart rate, breathing, sweat and blood flow.Beeler said some think they can beat a lie detector by altering their bodily responses, but he added that polygraph examiners are trained to know what normal and abnormal readings look like.He said claims that polygraphs are a pure coin-flip or that they are perfect are both wrong, calling it 'an amazing tool.' Beeler called lie detector tests 'an amazing tool,' adding they are not easily fooled, but also not perfect Brad Beeler worked for the US Secret Service for 25 yearsBeeler's strongest and quickest signal someone is lying, he said, is the liar's 'vocal soundtrack.'He pointed out someone giving a delayed or high-pitched 'no' or mismatched head shakes with their words.Beeler added that clear, black-and-white questions should get firm, quick answers, not 'squishy' ones.However, he stressed that these 'tells' in the LIARS system are more like yellow or orange flags, rather than a guaranteed red flag that someone is hiding the truth.Beeler compared it to the 'check engine lights' in a car, recommending that people use these signs carefully so you do not alienate friends and family members by instantly accusing them of lying.
