It’s tough to change our behavior radically, or even significantly. It’s easier to give ourselves a nudge towards utopia. Some real-world examples of the nudge are putting fruit at the front of the school lunch line instead of pizza, because hungry kids (and let’s face it, adults, too) often grab whatever is closest to hand; or the new Illinois policy that changed the wording for the organ donor program so that drivers have to explicitly opt out of being an organ donor instead of signing up to participate in the program, a simple change that saves the lives of many. These nudges are examples from Cass Sunstein and Richard Thaler’s book Nudge: Improving Decisions About Health, Wealth, and Happiness. In the book they suggest useful nudges that help us behave or perform better than we might otherwise. Others are from A. J. Jacobs, author and personal experimenter extrordinaire.
