The term "Mock jury" refers to a type of group research that allows lawyers to evaluate the potential reactions of jurors to their evidence and arguments before a case goes to trial. Typically, a mock jury consists of eight to 12 "Jurors" who are assembled to hear a summary presentation of both sides of a case. Once the case is presented, participants then discuss the evidence and the arguments. Generally, lawyers observe the group discussion from behind a one-way mirror or via remote video transmission. A typical mock jury discussion lasts one to two hours.
