Section 905.065 - Honesty testing devices(1) DEFINITION. In this section, "honesty testing device" means a polygraph, voice stress analysis, psychological stress evaluator or any other similar test purporting to test honesty.(2) GENERAL RULE OF THE PRIVILEGE. A person has a privilege to refuse to disclose and to prevent another from disclosing any oral or written communications during or any results of an examination using an honesty testing device in which the person was the test subject.(3) WHO MAY CLAIM PRIVILEGE. The privilege may be claimed by the person, by the person's guardian or conservator or by the person's personal representative, if the person is deceased.(4) EXCEPTION. There is no privilege under this section if there is a valid and voluntary written agreement between the test subject and the person administering the test. A distinction exists between an inquiry into the taking of a polygraph and an inquiry into its results. An offer to take a polygraph is relevant to an assessment of an offeror's credibility. State v. Wofford, 202 Wis. 2d 523, 551 N.W.2d 46 (Ct. App. 1996), 95-0979. The results of polygraph examinations are inadmissible in civil cases. While an offer to take a polygraph examination may be relevant to the offeror's credibility, that a person agreed to a polygraph at the request of law enforcement has not been found admissible and could not be without proof that the person believed the results would accurately indicate whether he or she was lying.
