Abstract
In response to lawyers' critiques of earlier staged-crime, mock-jury studies, 16 eyewitnesses to a staged crime were videotaped while being questioned by lawyers in a real courthouse. Accurate and inaccurate eyewitnesses were questioned by experienced or inexperienced lawyers for the prosecution and defense. Subsequently, 178 University of Alberta undergraduates served as mock-jurors and attempted to detect the accuracy of the witnesses based on their taped testimony. As in the previous research, the overall rate of belief was quite high (69%), and the subjects believed the testimony of accurate and inaccurate eyewitnesses at about the same rate (68% vs. 70%, respectively). Lawyers' experience failed to influence verdict. Confidence of the eyewitness was significantly related to belief of their testimony. The data replicate the previous findings and demonstrate that lack of expertise of the questioners does not account for the failure to detect eyewitness accuracy in this paradigm.
