Citation and Abstract
Procedural bias in forensic science examinations of human hair.
Miller, Larry S.
Law and Human Behavior, Vol 11(2), Jun 1987, 157-163.
Trained 14 students enrolled in advanced college crime courses in human hair identification techniques. Each S was given 4 hair samples to examine and render an opinion. Possible sources of influence or bias that may be responsible for examiner errors are considered. Results of the experiment that compared the conventional examination procedure (known vs questioned samples) against an alternative procedure (a lineup of samples) designed to limit the influence of factors that contribute to error show that the alternative procedure produced fewer incorrect conclusions (3.8%) than the conventional procedure (30.4%).
