How to Detect a Lie

Wow, your facts were quite informative. It's quite interesting that even college students scored higher than federal polygraphers, considering that they doing more lie detecting than students. I wonder what other behaviors are exposed when someone lies to another?

I think it would be very hard to find a method that can accurately detect lies close to 100% of the time, especially because there are some who are skilled at lying and manipulation. I'm doing a paper on psychopathy; because psychopaths do not feel remorse or guilt, they don't have the "twitches" or characteristic behaviors of lying, and they also don't exhibit autonomic responses such as sweating or change in heart rate when lying, making it very difficult to evaluate them.

This is an interesting topic. Many people tell lies, and it's always hard to tell them apart from the truth, when the person is really good at lying! Most of the time when I tell fibs, I can't resist laughing in my head, and I eventually spoil them. But there's always those good liars where you could not tell if he was lying or not. I definitely think that the eyes shifting thing and voice changing thing is true. Also, sometimes it funny when people lie and their face turns really red, that is hilarious but sucks for the person.

Interesting. I'm a person who is really not good at lying. When I lie to the others, people will say:"Look at your wired facial expression, you must tell a lie." I always curious when I people lie to the other, what difference will he look like.

I found some interesting sites on Stumbleupon over the last year that talked about nonverbal cues and lying. I guess you could say that I became somewhat obsessive compulsive about body language and always tried to control my nonverbal cues (kinda weird, I know). However, knowing some of these cues has helped me determine when someone is telling the truth or B.S.-ing me.

I find this to be a really interesting concept. I have started to try and pick these things out when I think someone might be telling a lie. I have definitely noticed eye shifting in people when lying and odd or unnecessary facial expressions. It is interesting too that some people can be really good at lying and others are really bad.

It is interesting to me how humans often trust machines more than natural observations.. I wonder how the secret service agents compare to the polygraph test!

Lie detection has always fascinated me. I think it would be interesting to understand the cues of lying better, but sometimes the truth hurts. So, I'm not sure that I would want to be as good at detecting lies as a Secret Service agent. I also have been very skeptical of polygraph tests because I think a person gets naturally anxious when put on the spot. If more non-verbal and verbal cues were analyzed, we may obtain more accurate results.
