Attorneys assume four roles when representing clients: advocate, advisor, negotiator and evaluator. Only the role of advocate requires conventional courtroom skills and tactics, while the other three roles of advisor, negotiator and evaluator mandate proficiency in a broader skill set that underpins decision-making expertise. This book assists attorneys, law students and clients to become expert decision makers. It summarizes decades of research regarding attorney-client decision making, introduces new data regarding the effectiveness of attorney-client decisions in adjudicated cases, describes the psychological and institutional factors that affect decision making, explains the legal malpractice and disciplinary consequences of poor quality decision processes and presents more than 65 ideas, methods and systems for improving personal and group decision making
