How to Detect Lies Through Questioning

Chris Chen
Once you know that someone is lying, how do you handle the situation? Remember that liars always have a reason to lie. If you notice someone who is lying about something casual, you should beware of that person's moral integrity in the future. If they lie in little things, they will certainly have no qualms in lying about more important issues. Also, reading deception is almost like a superpower and as much as I hate to say this, that clichéd Spiderman saying, "With great power comes great responsibility," applies beautifully here. Do not flaunt your abilities. Something like lie detection is a very sensitive topic. Also, don't accuse directly because it is the fastest way to lose friends. Now with that said, let's see how you can become a human lie detector.

You want to ask questions that are not direct accusations but might trigger a response in a guilty person. If you think someone took your box of Cheez-Its, you would say "Do you know where my Cheez_Its went?" If they become defensive about it, it is a good sign that they are hiding something from you. Another tactic is to ask the one you want to accuse for help in a way that alludes to what he did. Let's use the same cheese its example. In that case, you would say "Someone took my cheese its last night, how do you think I could find him." If he has nothing to do with the disappearance of your cheese its, then he will likely offer his help and advice. Instead, if he is guilty, he will offer you a moral lesson, saying that he would never engage in such shady activities. From here, you can move on. You can now make a general scenario that alludes to what happened. For example, you would say "It is amazing that people steal my cheese its even though I was watching them the whole time." If the person is guilty, they will quickly change the subject but an innocent person will likely find the topic interesting and try to continue the conversation because he is not afraid to discuss it.These three methods will only let you know if the person is lying, not exactly what he lying about or if it even concerns you. If the accusation is not important, I suggest that you usually drop it. Also, don't probe too far into the business of other people. Have the decency to never tell someone else that they are being lied to when it comes to topics such as relationships.
