Nudges
A “nudge” is a gentle push a friend gives you/to get your attention.// However,/you can also be nudged by strangers/for other purposes.// What’s more,/you may not even know what’s happening.//

　　You are at a subway station/in Stockholm,/Sweden.// You get off the subway/and look for a way/to get to the street.// You find stairs of black and white keys/—like huge piano keys—/leading up to the exit.// When you step on the keys,/they make piano-like sounds.// You can take the escalator if you want,/but you’ll probably choose the musical stairs/because they are so much fun.// At the same time,/you will be exercising.// The experimental piano stairs/resulted in a 66% increase/in the use of steps.//
　　A “nudge” is a little change/that leads you to do something/you may not have planned to do.// Nudges came to popular attention in 2008/when Richard H. Thaler and Cass R. Sunstein/published Nudge:/Improving Decisions about Health,/Wealth,/and Happiness.// The basic idea is to design an environment/which makes it easy for people/to do the right thing,/or at least to do/what you want them to do.// In many countries,/nudges have proved to be effective.//
