摘要: In deciding the trustworthiness of eyewitness testimony, U.S. judiciary employs as one five criteria witness' level confidence demonstrated at confrontation. A very recent laboratory study has shown that juror perceptions witness account for 50% variance in judgments to accuracy. This strong faith adequacy certainty a predictor accuracy is not all supported by present review 43 separate assessments accuracy/confidence relation eye- and earwitnesses. Statistical support provided notion predictability from overtly expressed varies directly with degree optimality information-processing conditions during encoding witnessed event, memory storage, testing memory. Low optimal conditions, those mitigating against likelihood highly reliable typically result zero correlation Using arbitrary criterion 70% or greater define high seven forensically relevant studies are identified, six them exhibiting significant positive correlations It concluded, however, no really clear currently exist distinguishing post hoc low witnessing any particular real-life situation. Hence should cease their reliance on an index
