Witness confidence and witness accuracy: Assessing their forensic relation

Jurors overbelieve eyewitnesses, have difficulty reliably differentiating accurate from inaccurate eyewitnesses, and are not adequately sensitive to aspects of witnessing and identification conditions. A major source of juror unreliability is reliance on witness confidence, a dubious indicator of eyewitness,accuracy even when measured at the time an identification is made, Confidence appears to be influenced by postidentification factors such as repeated questioning, briefings in anticipation of cross-examination, and feedback about the behavior of other witnesses. Juror reliance on witness confidence appears to be unaffected by traditional safeguards such as cross-examination and judges' instructions in eyewitness cases, Expert psychological testimony on the factors that influence eyewitness memory, in contrast, appears to reduce juror reliance on confidence and enhance use of other factors known to affect memory.
