I think that it is good that technology is being used to help detect deception, and I just wish it were more accurate because it becomes a double edged sword - especially with truthful people whose nonverbals are misinterpreted due to poor training with inaccurate methods, such as LVA or polygraph, etc.

This is one reason why attorney's advise their clients to retain counsel prior to being "interviewed" by law enforcement, because "anything you say (or do) can and will be used against you":

Q. What is the Employee Polygraph Protection Act? How does it apply to government agencies like police departments?

A. The Employee Polygraph Protection Act of 1988 (29 U.S.C. Chapter 22) is a law designed to protect private sector employees from polygraphs and other purported lie-detection devices. It was enacted in the wake of numerous allegations of abusive behavior by polygraphers and after a number of studies concluded that polygraph accuracy was unacceptable. A number of prominent organizations such as the American Medical Association and American Civil Liberties Union testified in support of its passage.

Generally, this law prevents private employers from even requesting that an employee or job applicant submit to a polygraph or any other type of "lie-detection" test (CVSA, etc.). There are a number of exemptions, which include:

* Employers under contract with the federal government for defense/energy/law-enforcement purposes;
* Employers whose primary business involves providing armored car personnel, burglar alarm system personnel, or security personnel whose function includes protection of facilities that have a significant impact on the health and/or safety of any state or municipality (power plants, water supply facilities, etc.);
* Employers authorized to manufacture, distribute, or dispense a controlled substance.

In addition, all private sector employers may request that any employee submit to a polygraph interrogation if the employer is investigating a specific loss. However, the employee has the right to refuse the polygraph in this situation and may not be fired/demoted/disciplined/denied promotion solely on the basis of this refusal.

Government employers, such as law enforcement agencies, are completely exempt from this legislation. This exemption applies to all levels of government: federal, state, and local. This means that government entities have carte blanche to use the polygraph however they see fit with virtual impunity.


Q. I would like to see the Employee Polygraph Protection Act expanded to provide protection from unreliable lie-detection for all Americans. How can I help?

A. The best thing to do its to write your representatives and urge that more comprehensive antipolygraph legislation be passed. The AntiPolygraph.org Get Involved page has sample letters and the addresses of several prominent senators who have shown some interest in this issue.


Q. I am a minority job applicant, and I recently "failed" a polygraph when I was truthful. Is it possible that racism, sexism, or other bigotry has contributed to my failure?

A. Certainly. While polygraph "false positives" affect those of all races, creeds, and colors, it is quite probable that this "test" is being used to carry out bigoted hiring practices in broad daylight. Because it can easily be manipulated by one person (the examiner), the polygraph is the perfect "tool" for circumventing an otherwise fair hiring process. A single "failed" polygraph can create an indelible negative mark on an otherwise outstanding applicant. Furthermore, in most circumstances, there is no right of appeal. Even if there is an appeal process, the applicant still faces an uphill battle -- after all, his/her credibility is suspect because he has "failed" a polygraph.

AntiPolygraph.org has been contacted by a number of minority applicants informing us that they were falsely accused by a polygrapher and that there may have been a racist element to their "failure." If you are in this situation, we suggest that you contact the NAACP by written letter and inform them of your situation and this website. Moreover, urge them to aggressively support closing the loopholes in the 1988 Employee Polygraph Protection Act and extending protection from polygraphs to all Americans.

It is troubling that there are many examples of abusive practices with polygraph/anti-lying devices:

And yet law enforcement insists on using it despite it's proven unreliability proven in scientific research.
