New though it may be, psychology has much to offer trial lawyers when it comes to jurors and juries. Each juror is an individual human being, and so, like all of us, can be better understood with cognitive psychology. Cognitive psychology has mapped out to an impressive extent how individuals perceive events, make sense of them, recall them, and report them. Juries, as groups, can be better understood with social psychology. Social psychologists have developed the science of how people cooperate and come to decisions together. Other branches of psychology can also be applied in the context of juror and jury research – all to the benefit of the trial lawyer.
