What is the essence of the Daubert standard?

• A. That all digital evidence is automatically admissible if authenticated
• B. That only tools or techniques accepted by the scientific community are admissible at trial
• C. That evidence must be obtained with a warrant
• D. That expert witnesses must be certified

Answer: (B)

The essence of the Daubert standard is that the judge must act as a gatekeeper to ensure expert testimony rests on scientifically valid and reliable methods that can be properly applied to the facts of the case. It’s not enough for an expert to be competent or for a method to be popular; the underlying technique must be demonstrably reliable. To judge reliability, Daubert looks at factors like whether the method can be tested or falsified, whether it has been peer-reviewed and published, known error rates, and the existence of standards governing its use, along with whether it has gained general acceptance in the relevant scientific community. These ideas together mean that only tools or techniques recognized as scientifically valid by the community are admissible at trial. Warrant requirements, expert certification, or automatic admissibility after authentication are not what Daubert governs.
