Polygraph or Lie Detection Services

Polygraph or Lie Detection: Polygraph testing and lie detection services are used when our clients need facts, and other investigation tools will simply not satisfy the nature of the inquiry or the due process of law. From criminal defense to domestic matters, our polygraph examiners can answer some of the most difficult questions.

As of 2014 ICS is no longer offering polygraph examination services directly. We are currently sub-contracting all polygraph services only in conjunction with investigation type cases. Polygraph examinations should be conducted as part of or proceeding a more complex investigation. Please complete a free consultation to learn about alternatives to polygraph testing services.

Are all Polygraph Testing and Lie Detection the Same?

  • Many polygraph examiners work alone and cannot meet realistic time schedules
  • Not all lie detection equipment is equal
  • Many are not credentialed
  • Many have a limited background and cannot "wordsmith" the right questions
  • Many do not ask admissible questions
  • Many will not work on referral not from attorneys

Polygraph testing and lie detection examinations are usually short and to the point. In many circumstances results are admissible in court. Although there is no Supreme Court brief to date on polygraph, many lower courts will admit.

  • Computerized

Examination Measures

  • Respiratory
  • Sweat Gland
  • Blood Pressure


  • Emotional Examination
