Reframing our understanding of justice and ethics, philosopher Barry Lam argues that while use of discretion--whether by a sports referee, a parent, a police officer, or a judge--can never be perfect, removing it has even more problematic effects. Mandatory arrests and sentencing laws have not eliminated bias, but have corrupted the courtroom, institutionalized lying, and brought about even more unjust and arbitrary results. Fewer Rules, Better People is a bold, riveting treatise that sheds new light on political debates about law and justice while aiming to prepare us for the imminent threat of more "perfect," discretion-less rule enforcement by AI.
