Wells, G. L., Kovera, M. B., Douglass, A. B., Brewer, N., Meissner, C. A., & Wixted, J. T. (2020). Policy and procedure recommendations for the collection and preservation of eyewitness identification evidence
. Law and Human Behavior, 44(1), 3.
This review was recently produced to update previous recommendations for eyewitness identification procedures published in 1998. It makes five additional recommendations to the four originally published.
The paper included a comparison of lab experiments with field study data not available at the time of the previous review. There is a risk that participants in lab studies might make more mistaken identifications because there are no real consequences. The paper compares the percentage of mistaken filler identifications in 6,734 actual lineups conducted by police investigators (23.7%) with those in lab studies (27.9%).
Another point I found interesting was the effect of base rates (prior probability of culprit being present) on the likelihood of mistaken identification of an innocent suspect. This is often neglected because there is a tendency to ignore base rates and wrongly conclude that the probability of a mistaken identification is based on eyewitness accuracy alone (as with ignoring base rates in medical diagnostic tests).
