Joe, you did a cut and paste from the abstract. You have not read the complete study, correct?

Further, my article was more of a micro-study, i.e., one examiner with 25+ years of experience running exams on clear-cut criminal issues in a police setting.

The fear/hope spot has been discredited by some of the higher-profile polygraph "scientists," but I disagree with them.

A countermeasure challenge series would help clarify things,  but the dedicated-to-truth fakers say such a thing would just be a "circus stunt."

In other words, they're chicken.

As to why I run tests, it's all supply and demand. But at least I make sure the client knows that polygraph validity is grossly exaggerated. Additionally, more and more of my time with clients is spent consulting, not testing.
