I have a feeling that this will turn out to be one of the most important books I’ve read, Gerd Gigarenzer provided much of the research material the Malcolm Gladwell used when writing his brilliant book, Blink. GG lays out rules of thumb the brain uses as short cuts to make decisions and create beliefs. He also demonstrates how these intuitions are often more effective than reason. These rules could prove a marvelous guidance system for how to construct effective suggestions – something I’m working on now.
