Gladwell includes caveats about leaping to conclusions: marketers can manipulate our first impressions, high arousal moments make us "mind blind," focusing on the wrong cue leaves us vulnerable to "the Warren Harding Effect" (i.e., voting for a handsome but hapless president). In a provocative chapter that exposes the "dark side of blink," he illuminates the failure of rapid cognition in the tragic stakeout and murder of Amadou Diallo in the Bronx. He underlines studies about autism, facial reading and cardio uptick to urge training that enhances high-stakes decision-making. In this brilliant, cage-rattling book, one can only wish for a thicker slice of Gladwell's ideas about what Blink Camp might look like. --Barbara Mackoff
