Research on lie detection has found that there is little correlation between accuracy and confidence. Additionally, nonverbal behaviors, such as eye contact and fidgeting, are not foolproof indicators of deception. Therefore, it is unclear whether the suspect is lying or not based solely on the other juror's confidence in their perception of deception. Furthermore, evidence such as a failed polygraph test is not admissible in a court of law and should not be considered as evidence for determining guilt.
