Daubert standard is used by a trial judge to determine whether an expert's reasoning or methodology is scientifically valid and can be applied to the facts.

• A. Admissibility of hearsay
• B. Scientific validity of reasoning or methodology
• C. Relevance to the facts
• D. Authentication of documents

Answer: (B)

The Daubert standard acts as a gatekeeping test for expert testimony, focusing on the scientific validity of the reasoning or methodology the expert uses to reach conclusions and whether that approach can be appropriately applied to the case facts. It isn’t just about whether the testimony relates to the facts; it’s about whether the underlying methods are reliable and scientifically sound. In practice, it considers whether the technique can be tested, has undergone peer review, has known error rates, is governed by standards, and is generally accepted in the relevant scientific community. If these criteria are met, the testimony is admissible; if not, it’s excluded. The other topics—hearsay admissibility, document authentication, and general relevance to the facts—are governed by different evidentiary rules and do not capture the Daubert gatekeeping focus.
