Nudge
Written by Richard R. Thaler and Cass R. Sunstein, Nudge is a blog about "improving decisions about health, wealth, and happiness" based on a popular book of the same name. Each post provides a great example of how little changes in perception can make a big difference. Plus, you'll feel smarter for reading. Recent posts cover ways to get people to take the stairs more often (think music and a view), a method for answering questions more accurately, and the benefits of using urinal flies when you have seven-year-old twins. The site's link roundups are especially interesting and will alert you to a scale that tells the world how much you weigh via Twitter and a recycling program that allows users to earn awards.
