ABSTRACT
During the COVID-19 pandemic, defendants and witnesses (as well as the prosecution and defense counsel) may wear medical face masks to prevent the spread of the virus. Alternatively, courtrooms proceedings may take place virtually. In this article, we discuss how these deviations from normal procedures may affect jurors' lie detection ability and decision-making. Although research addressing this specific question does not exist, we are able to formulate an informed view based on the extensive deception literature. Since nonverbal signs of deception in the face and body are virtually absent, we conclude that medical face mask-wearing or virtual courtroom proceedings will not hamper jurors' lie detection abilities. If jurors can hear the speech well, they may become better at detecting deception if they pay more attention to speech content, which may occur as a result of mask-wearing in the courtroom.
