1923 Frye v. United States sets the general acceptance standard for scientific evidence 0 cit. A federal appeals court ruled that a precursor to the polygraph, a systolic blood pressure deception test, could not be admitted as evidence because the underlying technique had not gained general acceptance in the relevant scientific community. The resulting Frye standard governed the admissibility of scientific evidence, including many forensic disciplines, in most U.S. courts for the next seventy years. It was eventually superseded in federal courts by the Daubert standard. politics / science ●●●
