[19], Although there is some debate in the scientific community regarding the efficacy of polygraphs, assessments of polygraphy by scientific and government bodies generally suggest that polygraphs are inaccurate, may be defeated by countermeasures, and are an imperfect or invalid means of assessing truthfulness. "[42], In Canada, the 1987 decision of R v Bland, the Supreme Court of Canada rejected the use of polygraph results as evidence in court, finding that they were inadmissible. It is all about how the operator interprets.
