This study examined the impact of MRI-based evidence on juror perceptions of guilt in a criminal case. Jury eligible undergraduates read one of three mock trial summaries of a murder case wherein MRI evidence was manipulated: (1) MRI evidence with accompanying neuroimages, (2) MRI evidence without accompanying brain images, or (3) no MRI evidence. The proportion of guilty verdicts rendered was statistically similar across all conditions. In addition, participants did not list MRI evidence as the most influential piece of evidence for their verdict. Based on the results of this study it appears that MRI-based evidence and neuroimages do not significantly influence the juror decision making processes. Implications and future directions are discussed.
