New research by a University of California, Riverside psychologist raises serious questions about eyewitness identification procedures that are being adopted by police departments across the United States.<\/p>\n
These new procedures are designed to reduce the kinds of false identification errors that can lead to wrongful convictions of innocent people.<\/p>\n
While it has long been held that these changes reduce false identifications with little or no loss of correct identifications, UC Riverside psychology professor Steven E. Clark suggests that that is not the case.<\/strong><\/p>\n The loss of correct identifications can be significant, Clark says.\u00a0 Importantly, the new procedures may, under some circumstances, lead to identification evidence that is less accurate than the identification evidence from the procedures they are designed to replace<\/strong>. Policymakers need to look very carefully at the data from empirical studies as they consider adopting new procedures, he cautions.<\/p>\n Clark\u2019s study, \u201cCosts and Benefits of Eyewitness Identification Reform: Psychological Science and public Policy,\u201d appears in the May issue of the peer-reviewed journal Perspectives on Psychological Science<\/em>, published by the Association for Psychological Science. It can be viewed online.<\/p>\n Clark has been involved in more than 200 criminal and civil cases, has consulted with prosecution and defense attorneys, and has testified as an expert in federal and state courts in six states, including California. Much of his research has been funded by the National Science Foundation.<\/p>\n In the paper, the psychologist notes that the reforms are directed at fundamental aspects of the identification process: How lineups are constructed, what witnesses are told and how they are instructed prior to the lineup, the way that the lineup is presented, and what police officers should and should not say and do during the identification procedure.<\/p>\n \u201cWhether policymakers decide to adopt or not adopt these new procedures is up to them,\u201d he says. \u201cIn order to make those policy decisions, they need to know clearly what the benefits are and what the costs are.\u201d<\/p>\n For some of the new procedures the cost-benefit trade-offs are clear.\u00a0 For other procedures, Clark suggests that the critical research has not been done.\u00a0 For example, one of the new procedures coming into use requires that the police officer who shows the lineup not know which person in the lineup is the suspect. In this \u201cblind\u201d procedure, the police officer would not know whether the suspect was second, third or sixth in the lineup. The blind procedure prevents police officers from deliberately or inadvertently cuing witnesses about who they should pick from the lineup.<\/p>\n \u201cThe principle behind blind lineup administration is solid,\u201d Clark says.\u00a0 \u201cIf the criminal justice system is concerned that the police might inadvertently communicate their expectations to witnesses, then a good solution is for the police to not have expectations by not knowing which person in the lineup is the suspect. However, many ideas that seem right in principle don\u2019t actually work, or have unintended side effects. The principle behind the blind lineup may be solid, but solid data would be better.\u201d<\/p>\n Clark\u2019s research examines the results from dozens of eyewitness identification studies that have been conducted and published over the last 32 years. The trade-off between false identifications avoided versus correct identifications lost is consistent, he says.<\/p>\n This trade-off raises an important question:\u00a0 How many correct identifications is the justice system willing to lose in order to avoid a false identification?\u00a0 Clark explains that under some conditions that trade-off may be very high, with many correct identifications lost for each false identification avoided.<\/p>\n Is that a trade-off that the criminal justice system is willing to accept?\u00a0 It depends, Clark says.<\/p>\n \u201cIn our justice system there is a view that a false conviction is a far worse error than a false acquittal,\u201d he says. \u201cHowever, false identifications do not always lead to prosecution or false convictions, and false nonidentifications do not always lead to false acquittals. This raises a question about the justice system\u2019s ability to correct its mistakes.<\/p>\n \u201cWhether the justice system prefers one eyewitness identification procedure over another depends on many factors, the nature of the trade-off \u2014 for example, how many correct identifications are lost in exchange for each false identification that is avoided \u2014 and what the consequences of those errors are.\u00a0 There are many other considerations as well, in terms of due process and procedural justice. \u00a0Policymakers have a lot to chew on.\u201d<\/p><\/blockquote>\n","protected":false},"excerpt":{"rendered":" From the UC Riverside press release: New research by a University of California, Riverside psychologist raises serious questions about eyewitness identification procedures that are being adopted by police departments across… Read more »<\/a><\/p>\n","protected":false},"author":4,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":[],"categories":[4],"tags":[289,12],"_links":{"self":[{"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/posts\/3340"}],"collection":[{"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/users\/4"}],"replies":[{"embeddable":true,"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/comments?post=3340"}],"version-history":[{"count":2,"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/posts\/3340\/revisions"}],"predecessor-version":[{"id":3360,"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/posts\/3340\/revisions\/3360"}],"wp:attachment":[{"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/media?parent=3340"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/categories?post=3340"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/tags?post=3340"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
