Rhode Island Weighing the Testimony of an Expert Witness is a legal process that determines the admissibility of expert opinion evidence. This process involves a judge deciding if an expert's testimony is reliable and relevant to the case. The judge considers the qualifications of the expert, the methodology used, any bias, and the logical consistency of the expert's testimony. The judge must weigh the probative value of the expert's testimony against its prejudicial effect. There are two types of Rhode Island Weighing the Testimony of an Expert Witness: Dauber Weighing and Frye Weighing. Dauber Weighing is a standard set by the U.S. Supreme Court in Dauber v. Merrill Dow Pharmaceuticals, Inc. (1993). This standard emphasizes the reliability of the expert's opinion. Frye Weighing is a standard set by the U.S. Court of Appeals in Frye v. United States (1923). This standard emphasizes the acceptance of the expert's opinion within the relevant scientific community.
