Nudge: Improving Decisions About Health, Wealth and Happiness by Richard H. Thaler, Cass R. Sunstein

4.0

“The picture that emerges is one of busy people trying to cope in a complex world in which they cannot afford to think deeply about every choice they have to make. People adopt sensible rules of thumb that sometimes lead them astray… they accept questions as posed rather than trying to determine whether their answers would vary under alternative formulations… People are, shall we say, nudge-able.”

“A nudge…is any aspect of the choice architecture that alters people’s behaviour in a predictable way without forbidding any options or significantly changing their economic incentives. To count as a mere nudge, the intervention must be easy and cheap to avoid. Nudges are not mandates.”
