About the Book: Why do we so often misjudge people, misinterpret events, and even mis-understand ourselves? We search endlessly for the causes of behavior, yet our explanations are frequently flawed. The reason lies in hidden mental shortcuts cognitive errors and biases-that quietly shape the way we think, feel, and act. This book uncovers the invisible forces behind irrational thinking and shows how they influence our daily lives. Drawing on insights from social psychology, it explores seventeen key themes that reveal why our minds so often lead us astray. From anchoring and adjustment to the status quo heuristic, from the planning fallacy to the optimism bias, from negativity’s dominance to the power of nonverbal cues each chapter demonstrates how these psychological traps distort judgment and subtly guide behavior.
