Human Factors Consultants specializes in providing legal expertise, consultation and testimony on eyewitness identification, including issues of perception, memory, line-up procedures, recovered memory; the factors that affect the accuracy of fingerprint comparisons; language, including comprehension, verbal and nonverbal harassment, children's understanding, memory and testimony; and safety failures, including human factors analyses of product design, warning, and training, and of accidents.

We have assisted clients in ten states and six Federal District court districts. We have been retained by both plaintiffs and defendants in over 75 civil cases, and by both prosecution and defense in over 75 criminal cases.

Lyn Haber and Ralph Haber have provided scientific expertise to the legal profession since 1980. We formed the partnership of Human Factors Consultants in 1987, and we work together on every case. We firmly believe that combining our complementary knowledge and skills provides better expertise than can a single expert, or a large firm of experts. Research has strongly documented that two heads working together are better than one. Our partnership is an instance: we offer the legal community the best consultative services and the finest understandable, scientifically based courtroom presentations available.

Ralph Haber received his Ph.D. in experimental psychology from Stanford University, his BA and MA from the University of Michigan and Wesleyan University, respectively, and post-graduate training in Cambridge, England in human factors from the Medical Research Council. He has held full time teaching and research appointments at Stanford University, Yale University, University of Rochester, and the University of Illinois, has been chairman of the psychology department at the University of Rochester, has held a full time research appointment with the United States Air Force, and has held visiting appointments at many other universities.

He has published 7 books and 250 professional scientific papers, and given over 100 conference and convention presentations.
