Reliable Methodology

Methodological Reliability, Reliable Principles and Methods

Why it Matters?

The Daubert factors are non-exclusive and fit poorly outside laboratory science, which is why courts assessing engineering, accident reconstruction, and medical causation testimony frequently examine whether the expert applied the same rigor they would outside litigation. That framing from Kumho Tire is often more productive than working through factors designed for a different context.
