The knowledge of experts presumably affects their credibility and the degree to which the trier of fact will agree with them. However, specific effects of demonstrated knowledge are largely unknown. This experiment manipulated a forensic expert’s level of knowledge in a mock trial paradigm. We tested the relation between low versus high expert knowledge on mock juror perceptions of expert credibility, on agreement with the expert, and on sentencing. We also tested expert gender as a potential moderator. Knowledge effects were statistically significant; however, these differences carried little practical utility in predicting mock jurors’ ultimate decisions. Contrary to hypotheses that high knowledge would yield increased credibility and agreement, knowledge manipulations only influenced perceived expert likeability. The low knowledge expert was perceived as more likeable than his or her high knowledge counterpart, a paradoxical finding. No significant differences across expert gender were found. Implications for conceptualizing expert witness knowledge, credibility, and their potential effects on juror decision-making are discussed.
This study examined the scope and components of mitigation assessments in a first effort to develop some guidelines for conducting mitigation evaluations. Using the Mitigation Evaluations Survey (MES) we developed for this research, we surveyed 266 psychologists about the characteristics and content of mitigation evaluations. A high percentage of participants endorsed each of the 14 content areas presented in the MES as essential or recommended for inclusion in mitigation evaluations. However, when the participants were given a hypothetical open-ended referral question regarding a mitigation evaluation, fewer participants included all 14 content areas in their responses. This discrepancy as well as information regarding the qualifications and expertise of the participants is discussed.
