Lie detector tests also known as polygraphs are still not allowed as evidence in most courtrooms in the United Sta
That's because some people have learned how to fool the machine by controlling their emotions. But according to the Discovery Channel, a new computer system can actually read minds. And it can't be fooled.
It's called Brain Fingerprinting. And it turns a criminal's memory against them.
How does it work? Well, whoever committed a crime will obviously remember the details. So, a suspect is hooked up to sensors that record brainwaves. Then, they're shown a series of words or pictures on a screen. Things that are relevant to the crime like evidence, names, places, and people's faces - and random images.
When the suspect sees something familiar, the electrical activity in their brain changes in a distinct way. And it can't be controlled. Then, all the operator needs to do is analyze the brainwaves, and they know whether the suspect is guilty or not.
Still skeptical? The FBI tested Brain Fingerprinting on their own agents. They wondered if it could tell who worked for the FBI, and who didn't. Volunteers were shown words and pictures that only a trained FBI agent would recognize. The test was 100% accurate in picking out the real agents from the fakes. And the FBI hopes to someday use Brain Fingerprinting to discover if someone is a spy, or a member of a criminal organization.
Brain Fingerprinting may very well become the evidence of choice in future criminal trials. Using a person's own memories to prove their guilt or innocence.
