Lie detector tests, also called polygraph exams, have been around for a long time to figure out if someone is telling the truth. Some bosses make job seekers take these tests before hiring them, and cops use them to help solve cases.
Even though lie detector tests can be scary, let’s take a closer look at what they’re all about.
What Happens in a Lie Detector Test?
A polygraph is a machine that watches how a person’s body reacts. It keeps an eye on their breathing, heartbeat, and sweat. During the test, the person gets asked questions, and the machine tries to see if they’re being honest by looking at the signals their body gives off. In a nutshell, a polygraph picks up on how someone feels when they’re answering questions.
To make sure the answers match up, the same questions get asked three times during the test. Depending on how the person answers, the lines on a chart will go up and down. When someone tells the truth, they usually feel calmer, so their answer comes out naturally. But if they’re lying, they might feel more stressed, trying to come up with a made-up answer. This stress can make the chart show bigger changes than when they’re telling the truth.
Not Everyone Trusts the Results
Some people don’t believe that lie detector tests are all that accurate. They say these tests don’t really measure if someone knows something hidden; instead, they show how a person reacts emotionally.
Sometimes, just being nervous about the test can make an innocent person’s body act all weird, like having a fast heartbeat or sweaty hands. This can make them look guilty even if they’re not. On the other hand, sneaky folks can stay calm and trick the test by acting relaxed even when they’re lying.
Polygraph tests can be useful in certain situations, like trying to get specific information. But they’re not perfect. Many times, judges won’t let the test results be used in court unless everyone involved agrees.
The Future of Lie Detection
A new way of spotting lies is on the horizon, and it might be better than the old polygraph. It’s called EyeDetect™. Instead of watching your heart and breathing, it pays attention to your eyes. You’ll be asked some true-or-false questions, and EyeDetect™ will study your eye movements to see if you’re telling the truth. It’s been getting about 85 percent of answers right, which is pretty good. In the coming years, EyeDetect™ could become the new go-to for figuring out who’s telling the truth and who’s not.
So, while lie detector tests have been around for a while, new technology like EyeDetect™ is changing the game. We’ll have to wait and see if it becomes the new superstar in the world of lie detection.
