Imagine having the power to predict whether someone will follow through on their promises or betray your trust. After the catastrophic events of 9/11, FBI Behavioral Analysis Program head Robin Dreeke confronted a harsh reality: he couldn't accurately predict the behavior of even those he thought he knew well. This realization launched his quest to develop a systematic approach to sizing people up - not just for national security, but because accurately reading others is one of life's most critical skills. His methodology transforms your ability to determine who deserves your trust with accuracy far exceeding the 50% success rate most achieve through intuition alone. The foundation of Dreeke's system is disarmingly simple: people almost always act in their own best interests. This isn't cynicism; it's human nature. Understanding this principle allows us to predict behavior by determining what someone perceives as beneficial to them. A colleague who consistently delivers projects on time does so not necessarily out of altruism, but because reliability advances their career prospects. By thinking like a behavioral analyst - objectively analyzing actions, statements, body language, and reputation - you can make clearer judgments even in high-stakes situations.
