The polygraph is sometimes useful to develop leads. Verify statements and crosscheck information. Moreover, it provides the police with a psychological advantage that may lead to a confession. Such confessions are admissible in court even though the test results are not. The proper tests are then determined, and the questions prepare and reviewed with the subject. After the test is completed, the subject and the police advised of the results in person or by letter. If the test indicates deception, an individual interrogation may follow. Any confessions that follow from such tests are almost universally accepted by the courts. The examiner's testimony is not conclusive evidence but rather opinion evidence regarding either guilt or innocence.
Polygraph results are generally not admissible in court-martial proceedings. The military courts typically follow similar standards to civilian courts regarding the reliability and validity of polygraph tests. While they may be used in investigations or as part of a plea deal, their results cannot be relied upon as definitive evidence in court.

Polygraph tests are generally not admissible as evidence in New York courts. The state considers them unreliable and lacks sufficient scientific validation for their results to be deemed credible in legal proceedings. However, they may be used in certain circumstances, such as for investigative purposes or in plea negotiations, but their results cannot be presented as evidence during a trial.
