Some Uses of Experimental Techniques in Forensic Human Factors

Abstract

Human factors experts in forensic practice are asked to analyze in post hoc fashion the effects of designs and warnings (or lack thereof) on occurrence and seriousness of accidents. Application of human factors principles in producing more adequate designs can provide evidence about whether or not an original design was faulty. The best test of the difference is an experimental one. Experiments were conducted dealing with warnings associated with freon, boxing headgear, and polio vaccine. The results indicate the usefulness of such procedures for confirming experts' opinions. The discussion includes consideration of the importance of testing all warnings for comprehensibility.
