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 100 citing decisions cite the case generally; a passage count includes only decisions quoting that exact language verbatim.
“If scientific, technical, or other specialized knowledge will assist the trier of fact to understand the evidence or to determine a fact in issue, a witness qualified as an expert by knowledge, skill, experience, training, or education, may testify thereto in the form of an opinion or otherwise.”
10 later decisions quote this exact passage“The test is not whether opinion testimony embraces an ultimate fact in the case, for that is the expected or desired result of specialized testimony. The test, restated, is whether the expert’s testimony, if believed, will assist the untrained layman trier of fact to understand the evidence or determine a fact in .issue ... and whether it is otherwise admissible under general rules of relevant admissibility. [[Image here]] Where specialized knowledge will assist the jury to understand the evidence or will assist them to determine a fact in issue, an expert may be allowed to provide the jury with the benefit of that knowledge. Two themes are prevalent within the language of the rule. First, the jury must not be qualified to intelligently and to the best possible degree determine the particular issue without benefit of the expert witness’ specialized knowledge. Second, the clear meaning of the rule must be observed.... The use of expert testimony must be limit ed to situations in which the expert’s knowledge and experience on a relevant issue are beyond that of an average juror.”
2 later decisions quote this exact passagee.g. Yount v. State · Speer v. State“[I]t cannot be said that each of us understands all facets of the problem, including why a child who has been abused will act in a certain manner which to the layman may appear unreasonable or inconsistent with a claim of abuse. Brogden’s information was both relevant and admissible under the rules of evidence, because it was specialized information of value in assisting the jury to understand the evidence regarding the complainant’s conduct.”
