About Human Factors & Ergonomics Expert Witnesses

Human factors and ergonomics experts analyze how people perceive, process, and respond to information and hazards in their environment, and whether a product or system was designed for safe human use 1. Attorneys retain them to evaluate the adequacy of warnings and instructions, estimate perception-reaction times, and assess visibility, conspicuity, and the role of human error in an incident 2. These experts apply established research on cognition, attention, and biomechanics — validated through the discipline represented by the Human Factors and Ergonomics Society (HFES) — to determine whether a person could reasonably have detected and avoided a hazard 3. Credentials such as the Certified Professional Ergonomist (CPE) from the Board of Certification in Professional Ergonomics (BCPE) reflect demonstrated competency in perception-reaction analysis, warnings, and usability evaluation 4.

The Board of Certification in Professional Ergonomics (BCPE) requires a graduate degree or equivalent coursework plus three years of full-time practice in the field before awarding the Certified Professional Ergonomist (CPE) credential.
