Nudge: Improving Decisions About Health, Wealth, and Happiness

No menu is neutral. The instant someone lays out options—food along a cafeteria line, funds in a retirement plan, boxes on an organ-donor form—they’ve already tilted the decision one way or another. Richard Thaler and Cass Sunstein build their whole book on that fact: since arranging choices is unavoidable, you might as well arrange them to help people, while leaving them free to go their own way. That’s a nudge—a small, cheap change to the environment that shifts behavior without banning anything or spending real money. Move the carrots to eye level and bury the fries, and kids eat up to 25% more vegetables. Etch a small fly into an airport urinal as a target, as Amsterdam’s Schiphol did, and spillage drops 80%. No lectures, no rules, just design that works with human nature instead of against it.
