‘The accuracy of criminal verdicts will forever be constrained by the imperfect human cognition that makes them possible.” This is the chief conclusion of Dan Simon’s extraordinarily thought-provoking book that links research into cognitive science to America’s criminal justice system. Simon, professor of law and psychology at the University of Southern California, brings a unique psychological perspective to the inner workings of the criminal justice system.
