Find a Human Factors & Ergonomics Expert →Overview
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.

FAQ
A human factors expert typically holds an advanced degree in human factors, ergonomics, experimental psychology, or industrial engineering, and may hold a Certified Professional Ergonomist (CPE) credential. Applied or research experience in warnings, perception-reaction analysis, or usability, along with prior testimony experience, is important.
These experts are retained in cases involving warning adequacy, perception-reaction time, visibility and conspicuity, workplace task design, and human error in product or system use. They help determine whether a person could reasonably have perceived and avoided a hazard.
In general, expert fees are determined by the expert themselves, based on a variety of criteria. Among those criteria are professional experience, forensic and testimony experience, relevant certifications, case-type specialization, and publications. Vident does have some influence over expert fees by comparing experts within a specialty, but ultimately it is a personal decision by the expert.
