What is the Daubert standard, and what is its role in admitting scientific expert testimony?

• A. It governs the mootness of scientific findings and their relevance.
• B. It requires the jury to determine scientific reliability.
• C. It governs the trial court's gatekeeping of expert scientific testimony, requiring relevance and reliability based on factors like testing, peer review, error rates, and acceptance.
• D. It sets sentencing guidelines for experts found to be dishonest.

Answer: (C)

The Daubert standard centers on the judge’s gatekeeping role in admitting expert scientific testimony, making sure it is relevant to the case and grounded in reliable methods. The trial court weighs reliability and relevance by looking at how the theory or technique has been tested, whether it has been peer reviewed or published, the known error rates, the existence and maintenance of standards controlling the technique, and whether it has gained general acceptance in the relevant scientific community. These factors guide a flexible, case‑specific inquiry rather than a rigid checklist, with the aim of preventing junk science from reaching the jury while still allowing valid expert testimony to assist fact-finding. Daubert applies in federal courts and many jurisdictions, and the emphasis is on the court’s evaluation of method validity for the particular issue, not on a jury’s determination of credibility or on sentencing considerations.
