Blink is a cool new book from the author of Tipping Point. Blink explores the ability of people to make extremely rapid decisions and analyzes what causes some of those decisions to be correct or not. You might have heard about the Harvard study which showed that students made the same assessment of a professor's competency after a 30 second video as when they took a class with him/her for an entire semester; Blink talks about this as one example of rapid decision ability, and points out that this test was able to be narrowed down to a two second video without sound! There are some other fun stories in here as well. ¶7:05 AM; digg
