Understanding Polygraph Results

The examinee was found to be truthful. NDI / NSR is the finding that the examinee has NO significant involuntary physiological reactions throughout the charts, reactions which may indicate a deception in one or more of the pertinent questions asked.

The examinee was found to be deceptive in one or more of the pertinent questions asked during the test. Significant changes in involuntary physiological reactions were consistently recorded, which can be explained as deception indicators.

As there are many potential reasons which may explain the inconclusive result, this result type is meant to increase conclusive test results’ reliability and validity. Inconclusive serves as a buffer zone out of an abundance of caution. An Inconclusive result often requires some explanation from the examinee and/or test question modification prior to administering a follow-up test. 

The examinee did not complete the test, or did not fully comply with the examiner's instructions, and/or the examiner did not have enough confidence in the integrity of the data gathered during the test.
