Eyewitness evidence often plays a critical role in decisions made in the criminal justice system. To evaluate eyewitness testimony accurately, judges must be aware of factors that can contaminate this type of evidence. In 2008, a survey of judges in Norway revealed a lack of awareness of several factors that affect eyewitness testimony. In the current study, a survey was administered to Norwegian judges (N=98) to evaluate their knowledge of factors that affect eyewitness testimony. Results showed that judges’ overall knowledge scores were similar to those reported in 2008, but substantial increases and decreases in knowledge were observed for specific factors. Additional analyses indicated that increased uncertainty regarding some eyewitness factors led to a decline in accuracy when compared to responses observed in 2008. The current study provides an updated assessment of judges’ knowledge of eyewitness factors and highlights the need for more comprehensive training for judges regarding these factors.

目击者证据通常在刑事司法系统中做出的决定中起关键作用。为了准确评估目击者的证词，法官必须意识到可能污染此类证据的因素。2008年，对挪威法官进行的一项调查显示，人们对影响证人证词的几个因素缺乏了解。在当前的研究中，对挪威法官（N = 98）进行了一项调查，以评估他们对影响目击者证词的因素的了解。结果表明，法官的整体知识得分与2008年报告的得分相似，但是在特定因素下，知识的增长和下降均显着。进一步的分析表明，与2008年观察到的反应相比，某些目击者因素增加的不确定性导致准确性下降。
