A computerized polygraph is similar to an analog polygraph instrument. The main difference is that the computerized version, instead of using mechanical ink pens and graph paper, makes its recordings on the computer's hard disk, and these can be printed out or viewed on-screen. Typically, the computerized polygraph also includes chart-scoring software.

But it's still the same voodoo. Computerization adds no more validity to polygraph chart readings than it does to astrological chart readings, and the criteria for passing a polygraph "test" remain the same, whether it's computerized or not.

To prepare for a polygraph "test," see Chapters 3 & 4 of The Lie Behind the Lie Detector.

Thank you for your help.  I've been told by my lawyer not to take a lie detector test.  She said it's like slitting my throat!  I have to do this to save my marriage.  I'm reading like crazy to get it down pat on how to pass this  test.  I'm also praying!

Teece,

One more reasonable demand upon which you should insist is that you video- and/or audiotape the entire polygraph process, from the beginning of the pre-test interview until the time you and the polygrapher part company. Plan for up to three hours.

Polygraph "testing" is a fraud that depends on the polygrapher lying to and deceiving the person being "tested" from beginning to end, and having the entire episode on tape will help to protect your rights.
