Most of us think that there are skilled liars and not-so-skilled liars, but professional lie catchers have many methods to detect a lie from almost anyone. Here are three more tips to help you tell whether someone is lying or not:
1.) Liars rehearse their stories before they have to say them. They are usually so locked into their story that any distraction can reveal the truth. While they are telling you what happened, try interjecting with “Why should I believe you?” Liars will usually calmly pick up the story where they left off whereas truth tellers will usually get angry and say “Because I’m telling the truth!”
2.) Another way to check on whether a story is true or false is to have them tell you the events backwards. Most liars rehearse they lies from beginning to end, but they have a much harder time telling the story in reverse.
3.) A final clue to whether someone is lying to you or not is how much body movement they are displaying. Like I mentioned before, liars are usually so locked into telling their story that they don’t act normally. Most of us use gestures or we act things out with our hands when we are telling a story – what Dr Paul Ekman calls “illustrators”. If someone is completely still for the duration of their story – they may be lying to you.
