If you do a search on the famous phrase “You can’t handle the truth!” from the movie A Few Good Men, you will find it in a list of useless movie quotes. Ironically, it was also voted as the twenty-ninth greatest movie quote of all time by the American Film Institute.
My point is that one should be very careful when handling the truth—especially if you’re a human resource (HR) professional. That being said, the use of polygraph (better known as a lie detector) testing in HR can be quite controversial. Obviously, in such sensitive fields as national security, the benefits of its usage are apparent. But how far should you go in other, less sensitive professions?
In North America, polygraph testing is very rarely used in HR and employers or recruiters that do use it need to thoroughly justify its use. The Polygraph Protection Act clearly states: “Employers are generally prohibited from requiring or requesting any employee or job applicant to take a lie detector test”. Refusing to take such a test should not impact the recruiter’s decision to hire someone nor should it be used as a basis to fire an individual when they are part of a criminal investigation. Furthermore, when people agree to take the test and fail, the results should not be used by the company to take actions against the employee. The results of the test can only be used as evidence when legal actions against the employee are initiated.
Things are quite different in other parts of the world. In Eastern Europe for instance, I found two HR consulting companies that use polygraph testing for both recruiting and employee assessment. In both cases, it is unclear what the rights are of the people being tested: the privacy of the employee/candidate seems to be at jeopardy.
The first company I reviewed is CHR. One of the advantages of using polygraph testing, as mentioned on its Web site, is that it can “estimate employees’ loyalty, motivation, and their personal features.” I wonder how this works. Does the company use the polygraph test when the candidate says that they would like to spend the rest of their life working for a company and share its values, vision, blah, blah, blah?
The second company I reviewed, Solo HR, seems to be a bit more innovative. It offers its customers the option to “use computerized polygraph called KRIS even in open air conditions!” So, the next time you take your employees out for a picnic, take a polygraph with you—it’s going to be much more fun and you can find out which employees are the most motivated!
There are no HR consulting companies in North America doing polygraph testing. When required, recruiters or HR professionals use the services of specialized companies (see the American Polygraph Association). From the same Web site, we also learn that “To date, there has been only a limited number of research projects on the accuracy of polygraph testing in the pre-employment context, primarily because of the difficulty in establishing ground truth.”
In conclusion, the use of polygraph testing in HR can prove to be useful under very specific circumstances (national security agencies, companies dealing with confidential data, lawsuits, etc.)—and it can be even ethical if we consider that the nation’s security is more important than the privacy of the individual.

Then, where do stand an HR recruiter qualifications?? isn’t he enough trained to be able to detect if someone is not being honest?should we rely on machines for everything??
it’s a pity,,
it is quite interesting to see new innovation of polygraph application in HR profession. however, i think we (HR Professional) should try strike a balance between the right of empolyee and employer. the polygraph test should also be use by the employer for the intending employee to know the true stand (Financial, Vision, Mission and Core Value System) of the company before joining.
Use of a polygraph for potential emlpoyees sets a very negative tone right at the beginning of the employee relationship. Psychometric tests are far better at determining trustworthyness and in determining fit, and a solid reference check will also provide the information you are requesting. Both of which provide more accurate results without teh negative associations of a polygraph.
@Sylvie Those qualifications should be enough in 99% of the cases, but what do you do when you hire people involved in national security activities?
@Segun Good point - I agree!
@Theresa I am a strong believer in psychometrics and i will write a post about this in the near future
What people do not realize is that a poly is nothing more than an elaborate psych testing tool that has been proven to be only 50% accurate at best. Of course law enforcement and several HR professionals state otherwise. In the state of New York, the use of polygraphs has been outlawed for employmetn screening because of their inaccuracies.
Mant times a person is a little nervous when undergoing this regime and a perfectly honest person will fail the test. At the same time, using well documented procedures it is child’s play to beat a poly.
This practice has been in the industry for many years. My first encounter was over 20 years ago; nearly every question was “Have you stolen … from … over … dollars?” Passing the polygraph was a requirement of employment. I was furious for weeks after passing it because I am an honest person, today I will not interview with an organization (outside DOD) that requires one. The test is as good as the interpreter, which is why its accuracy rate is so bad and why the polygraph law was passed.
If the HR folks are willing to take the test on themselves while making commitments on the role and career path (in addition to the test on the candidates), then this can be worth a try. Otherwise it is a win-lose proposition.
@William: Interesting that you mentioned that- i just found an article about this: How to cheat a polygraph test (http://www.wikihow.com/Cheat-a-Polygraph-Test-(Lie-Detector))
@John: It is offending and makes you feel guilty until proven innocent!
@G Sriram: Some kind of Hippocratic Oath for HR people? Not a bad idea!
For the most part, I would be inclined to distrust a company that does this. How would I know that officers and senior managers are held to the same criteria? This is another reason why the shifting of more of the hiring responsibility and decision making from the hiring manager to HR very often results in poor hires.
The polygraph is not allowed in the courtroom because it is notoriously unreliable, even when used by experienced professionals. I doubt most HR departments have skilled professionals on staff. Why limit the question to polygraphs? There are other surreptitious ways to invade potential employees’ privacy - two that have been talked about publicly are reverse speech and micro-tremor analysis.
If my HR manager announced that he/she wanted to introduce polygraph testing for recruitment or for any other people management activity I would immediately fire the HR manager and also quickly make an annoucement that I had done so.
If my HR manager/staff cannot do their jobs without such testing then they are totally incompetent and have an attitude which I would never tolerate.
In fact If my HR manager had this attutude to managing my staff then I would be very angry with myself for ever hiring that HR manager.
Recruitment does need to be more professional in many organizations, using ethical and professional methodologies to find the best match candidates
People are the capability and the power house of every organization, they must be treated as critical to the business, the whole management of the organizations needs to behave and communicate in a way which encouraged the staff to be engaged and to be innovative and creative, at all levels, and management at all levels needs to conti uously show all staff that they are respected as critical to the business and respected as human beings.
Using polygraph instantly makes a divide between the organization management and the staff and would be a ‘killer’ of engagement and creativity.
It would instantly kill trust, kill open dialogue, and would prompt the staff to think in terms of them being accused of lying, etc.
Absolutely no way!
