Did you know that the Target ads you receive in the mail are probably different from those in your neighbor's mailbox? How about this: Compulsive gamblers perceive near-misses as wins while more casual gamblers perceive them as losses. So, from lottery tickets to slot machines, gaming designers include a lot of near-misses to snare compulsive gamblers. Filled with interesting anecdotes, The Power of Habit provides insights into how habits are formed, and they can be broken. (Turns out it's not easy to break a habit.) If you just want the how-to part of understanding and changing habits, go straight to the appendix. I wish this book dealt more directly with the realm of education, but maybe that will come along eventually. The part about how social movements are formed was the weakest section, but the other case studies are fascinating.
