Most-quoted passages
The sentences later courts lift from this opinion, ranked by how many decisions quote each — the parts of the opinion doing the work. These counts are smaller than the citation total above because most of the 5 citing decisions cite the case generally; a passage count includes only decisions quoting that exact language verbatim.
“' "A study of the theory and process of the polygraph examination reveals complexities not present in the fields of fingerprint, handwriting, voice print, ballistics, and neutron activation analysis, all of which are based on the identity or behavior of physical phenomenon. The experts and studies differ as to the capability of the polygraph industry to cope with these complexities, but none would dispute their existence. The distinction is that polygraphy, albeit based on scientific theory, remains an art with unusual responsibility placed on the examiner. The acquainting of the examiner with the subject matter is often a source of improper suggestion, conscious or subconscious. The preparation of the test and discussion with the examinee of the polygraph procedure furnishes additional opportunity for improper subjective evaluation. The construction of the examination further proliferates controversy, for while experts may agree that a particular examination was inconclusive, they often do so for different reasons.””
1 later decision quote this exact passage“We foresee very few circumstances under which the “results” of a polygraph test would ever be admissible. The potential for prejudice resulting from the jury knowing whether a defendant passed or failed a polygraph test would far outweigh any probative value that such evidence might have in determining the voluntariness or involuntariness of a subsequently or previously obtained confession. While the “fact” that the test was taken may be relevant under some circumstances to the voluntariness of a confession, the actual results of the test would ordinarily have very little, if any, such relevance.”
