What was the outcome of the Frye v. United States case regarding polygraph tests?

The outcome of the Frye v. United States case established that polygraph tests were not admissible in court primarily due to concerns regarding their reliability. The ruling highlighted that scientific evidence must be not only relevant but also accepted by the relevant scientific community to be considered admissible. In this case, the court found that the results of a polygraph test did not meet the necessary criteria because the accuracy and consistency of these tests were still under debate among professionals.

This landmark case set a precedent for the admissibility of expert testimony and scientific evidence in the legal system, emphasizing the importance of reliability and general acceptance within the scientific community. Thus, the decision effectively limited the use of polygraph tests in judicial proceedings, reinforcing the notion that scientific methods must be sufficiently established to be considered legitimate in a court of law.
