How to Tell if Someone Is Lying
Want to know if someone is lying? You'll learn a few tricks
for that here, but be careful. All methods of lie-detecting,
including polygraph machines, are regularly fooled or used improperly,
resulting in mistakes. There are many worthy lie-detection techniques,
but try to confirm the truth by other means as well, such as
confession or investigation of the facts.
Compare behavior in the person under suspicion to their "base"
behavior, if possible. In other words, if they always have shifty
eyes, then this trait can't be considered as an indication of
lying. On the other hand, if they are normally very calm under
pressure, but start shifting in their chair after certain questions,
that may indicate lying. Because all techniques fail at times,
you should use several indications before assuming the person
How to Tell if Someone Is Lying by Testing Responses
A simple way to test for lying, is to measure a persons desire
to avoid a subject, which will sometimes indicate dishonesty
or guilt. If you think the person is lying, change the subject
quickly. A lying person will often go along easily, and may even
visibly relax. An innocent person is more likely to be slightly
confused by the change and want to finish their thoughts.
Another lie detecting technique is to suggest something that
would make a guilty person feel uncomfortable and watch for a
response. Suppose your wife Jane says she was at her mother's
house, and you think she is lying. Rather than saying, "I'm
calling your mother to verify this," you could use a subtle
approach. You might say, "That reminds me, I'm going to
stop by your mother's house today to fix that door for her."
If your wife was lying, the idea of you seeing her mother
should make her nervous. She may give you reasons why you shouldn't
go there. Of course, if your relationship has reached the point
where you feel the necessity to resort to these techniques, a
simple lie may not be the worst of your problems. Still, sometimes
you need to know, so here are a few more ways to tell if someone
They are using your words. Using your exact words to respond
can be an indication of lying. You say, for example, "Did
you leave this here?" and they respond, "No, I did
not leave this here."
They use un-contracted words. A lack of contractions is more
common when lying. For example, instead of saying "I didn't
sleep with her," a man might say," I did not have sexual
relations with that woman." Again, compare to base behavior,
though, as some people may not use contractions often anyhow.Over-compensation.
Often when people lie, they try too hard to be natural, and they
give more detail than is necessary.
Forced smiles. A real smile involves more muscles, while a
forced smile will use just the muscles around the mouth. The
lie here may only be about their feelings, of course.
Always let them talk. The more a person talks, the more likely
you are to catch them in a lie (if they are being dishonest),
especially when you learn the indications to watch for. These
are just a few of the ways you can detect a lie.
