One or two occasional lies might not get you into trouble, but you can face the danger of adopting this as an acceptable way of communication and start lying in every aspect of your life.

There are many signs you can look for in people if you want to find out if they are telling the truth. You don’t have to be a private investigator to be able to get into a person’s mind.


The first sign that a person is lying is the nervousness they would feel. Can you blame them? They keep thinking about not being caught and on top of that they have to remember what they have said so they wouldn’t look suspicious. However, being nervous doesn’t necessarily have to mean that the person is lying, so it might be misleading.

More Time To Come Up With A Reply

You might be better off by keeping track of the time the person needs to reply. People who lie often need more time to come up with a reply. This thinking represents an additional “cognitive load”, as your brain needs to work harder, faster. Not only does the brain need to think about the lie, it should also focus on supressing the truth. That can be quite a challenge, especially for those who are not used to lying.

Body Language

Another sign would be the body language. Reading the movements of the body has proven to be a real asset for Private Investigators who have the ability to turn into human lie detectors and find out whether the suspect is telling the truth. People who are nervous would blink, fidget and maybe walk around, whereas people who are lying will be so focused on their lie that they would probably be stiff and try to be as calm as possible.

There are several techniques you can use to check if someone is lying. These techniques are often used by private investigators and they have proven to be very effective.

Make Them Think More

One of the ways is to increase the “cognitive load” of the person you are suspecting is lying by making them think more. If you ask them to tell their story starting from the end all the way through the beginning you will make their lying more difficult. Then you can ask a lot of questions. You can start with something that is more general and then slowly progress to more detailed and specific questions. Once you get to the details of their story it will be even harder for them to stick to their lie.

Beware Of Liars As They Are Pretty Smart And Tricky People

Be aware that people who lie are not stupid, in fact they are very intelligent. It takes a lot of effort and talent to be able to come up with a good lie. The ability of lying shows in the early phases of life and it can be an indicator whether the person will develop into a creative individual.
