About

The field of Human Factors originated during World War II to address issues of human performance in the U.S. armed forces. Costly failures due to error created an urgent, fresh, multi-disciplinary approach to design and accident analysis. Today, a Human Factors professional, also known as a Human Factors Engineer or Ergonomist, applies theory, methods, and principles based in psychology, engineering, and neuroscience to study the way people and technology interact, particularly in relation to how and why people respond (or not) to certain stimuli that are safety critical.

Dr. Joe Cohen is the Principal Consultant for Error Analysis. Joe is a board-certified Human Factors Professional (CHFP) and Hazard Control Manager (CHCM). During his career, Joe has personally investigated more than a thousand injury cases for legal clients in fourteen American states.  As a consultant or expert retained for litigation, Joe routinely addresses Human Factors issues in premises safety, product warnings, and forensic aspects of human performance in traffic crashes. His career project work has included clients such as Boeing, Con Edison, Zamboni Company USA, United Brotherhood of Carpenters, and the Coffee Bean & Tea Leaf. 

H. Harvey Cohen founded Error Analysis. His work significantly advanced the practice of Human Factors in claims and litigation, most notably in the areas of occupational safety and personal injury. This followed a celebrated career of public service, scientific research, consulting, and writing. Among several other books, Dr. Harvey Cohen is a co-author of Slips, Trips, Missteps, and Falls: Causes and Prevention (3rd Edition, 2021), published by Lawyers & Judges Publishing. Harvey retired from consulting in 2017. He entered full retirement in 2023.

Forensics

Personal injury claims in litigation are the primary source of Error Analysis’s work. We review case files, inspect accident sites, research, test, and may form opinions in disputed matters about issues in causation and liability. Typically, our cases involve personal injury due to falls, collisions, exposures, and/or repetitive motions. Within the field of Human Factors, our specialties are hazards and risk, standards and violations, warnings and instructions, unsafe acts, attention and decision- making, hazard response and avoidance, impairments, and the fundamentals of biomechanics.
