How can you know if anyone is lying? Take it slowly. Both lie-detection techniques, like polygraph devices, are regularly deceived or misused, resulting in errors. There are a few useful methods listed here, but you can still try to prove the truth by other methods, such as confession or truth.
If at all practicable, you can relate the suspect’s actions to their “core” behavior. In other words, if they always have shifty eyes, then this trait can’t be considered as an indication of lying. If, on the other hand, they are usually very relaxed under pressure but start moving in their chair after some questions, this may mean that they are lying. Because all methods fail from time to time, you can look for multiple signs before concluding that the individual has lied.
One way to detect lying is to assess a person’s intention to escape a subject, which may mean dishonesty or guilt. If you suspect the individual is lying, quickly change the subject. An individual who is lying will usually go along with ease and may even seem relaxed. An uninformed person is more likely to be perplexed by the transition and want to finish their thinking process.
Another tactic for catching lies is to say something that will make a guilty person feel uneasy and then wait for an answer. Let’s imagine your wife Jane claims to have been at her mother’s home, and you suspect she’s lying. You should use a clever solution instead of shouting, “I’m calling your mother to check this.” “That reminds me, I’m going to stop by your mother’s house today to repair that door for her,” you might say.
If your wife is telling a lie, the prospect of you visiting her mother should give her a chill. She might try to persuade you not to go there. Of course, if your relationship has deteriorated to the point that you feel compelled to use these methods, a mere lie may not be the worst of your problems. Still, there are moments that you need to know, so here are a couple more ways to spot a liar.
They’re making use of your words. It’s possible that responding in your actual wording is a sign of lying. “Did you leave this here?” you may ask. “No, I did not leave this here,” they answer.
They use terms that aren’t contracted. When lying down, a lack of contractions is more likely. Instead of saying, “I didn’t sleep with her,” a man might say, “I had no sexual contact with that lady.” Compare to baseline behavior, since some individuals do not use contractions too much in the first place.
Overcompensation is a term used to describe when a person compensates too much. When people lie, they always try too hard to be normal, to have more information than is needed.
Smiles that are forced. A genuine smile uses more muscles, while a forced smile uses only the muscles surrounding the mouth. Of course, the deception here might only be about their emotions.
Enable them to express themselves. The more a person speaks, the more likely you are to catch them lying (if they are lying), particularly after you understand the signs to look for. There are only a couple of the methods for determining whether or not someone is lying.
