I hear this kind of nonsense often...."He has conducted over 10,000 polygraph examinations"  and similar. Doing the same thing wrong for 20 years simply makes one worse, not better.

The methods described in The Lie Behind the Lie Detector can reduce, but not eliminate, the risk of a false positive outcome. It is true that hand-scoring introduces subjectivity, but it should be borne in mind that polygraphy is pseudoscience to begin with, whether or not a computer scores the charts.

Will this really work?? 

What if they hand grade it?

I'm sorry (but not surprised) to read of your unfortunate experience. False positives (a truthful person being wrongly branded as deceptive) are quite common in polygraphy. You'll find suggestions for reducing the risk of a second false positive in our book, The Lie Behind the Lie Detector, which you can download here:

See especially chapters 3 & 4.

I recently took a polygraph test and told the truth and the polygraph examiner told me he thought I was lying and I had failed. This examiner said he has 20 years experience as a polygraph examiner. He graded his test by hand and did not use the computer to grade.

The funny thing is, I took a polygraph test and passed with pretty much the same questions, same everything. It was graded by computer, but I passed with flying colors. 

I've heard when the chart is graded by hand it's more subjective. I don't know what to do. I told the truth, but I need to pass. What do I do? How can I pass?

PLEASE HELP!!!
