The USB Lie Detector

The results of a polygraph machine, known as a “lie detector”, has been repeatedly proven to be inaccurate at best, and wildly misleading in most cases. Official court opinions (including those of the Supreme Court) have been issued stating that polygraph results cannot be used as evidence due to their inaccuracy.

Of course, the manufacturers of Real Lie Detector: USB Polygraph have chosen to ignore this, going instead with the pitch “Easy to use. Hook up your friends and get the truth.”
