As much as I want to believe this, I am having some doubts. Like, what if something happened so long ago, that I forget it. Perhaps, no one could forget comitting a murder.
|The most popular method of lie detection in use today is the polygraph machine, developed in the 1930s, but its accuracy is widely disputed. That's one reason why, in the Department of Justice's investigation of the more than 1,200 people so far detained in the investigation of the Sept. 11 attacks, the polygraph may be joined by at least one new lie detection mechanism. |
It's been dubbed "brain fingerprinting" by its architect, former Harvard Medical School faculty member Lawrence Farwell. Farwell's lie detection method kicks in before a person even has the chance to lie by looking for a telltale brainwave after a subject is flashed a cue having something to do with the crime — such as the murder weapon, the direction the victim was facing, etc. That brainwave only appears if the person has a memory of that information stored in their brain.
In that way, says Farwell, "it doesn't really detect lying at all. It detects information stored in the brain. But if someone has committed a crime, they have a record of that in their brain, and we can detect if they have the details of a specific crime stored in their mind."
