Koh Younghoon, a board member of the Korean Association for Public Interpretation and Translation (professor at the College of Occidental Languages, Hankuk University of Foreign Studies) published a translation of Sizing People Up: A Veteran FBI Agent’s User Manual for Behavior Prediction on August 13, 2020. The book introduces six manuals that predict people’s behaviors, created by FBI behavioral analysts through decades of rich field experience and research. If you learn this manual, you can identify fraudsters and resist those that try to manipulate psychology, just like agents at the world's largest and best investigative agency. This is because you can read their inner thoughts from their actions. In relationships with friends, colleagues, lovers, and bosses, or in business relationships, you will learn to predict whether or not the other person will be your ally or enemy, how the other person will behave in important situations, and why.
