You might like Blink, by Malcom Gladwell
"In Blink, Malcolm Gladwell (author of The Tipping Point) explores the experience of making quick, impulsive decisions. There are those who are brilliant decisions makers who often make their judgement in the blink of an eye, and those who constantly fail at the same task. What makes the difference between the two and how do the successful decision makers instantly process the information that leads them down the right path? Gladwell introduces the concept of "thin-slicing," being able to filter the important information from a multitude of variables. He shows examples of how this can be done and how it can be blocked by prejudices already in place."
