Your article has made me feel more relaxed about the polygraph examination. I have only seen it in Hollywood movies being used to interview individuals especially in cases where the stakes are high or in law enforcement.

I never thought it could be used as a pre-employment tool. I appreciate the need for it in the investigation of fraud. Banks in Nigeria need that technology because it usually happens that when a fraud is committed, members of the unit in which it happened are relieved of their duties or worse, prosecuted without any persons trying to discover the truth and each individual's culpability.

Thanks for the education.
