Nudge

by Richard H. Thaler and Cass R. Sunstein

Three key ideas

  1. Every layout steers attention. Order, wording, defaults, and effort all shape a decision.
  2. Judge a nudge by actual freedom to choose otherwise, not by what the designer calls it.
  3. A default applies when you do nothing, and it can steer outcomes.

The five 2-minute lessons

  1. 1.Notice the layout behind the choice
  2. 2.Keep a real way out
  3. 3.Defaults: starting points, not answers
  4. 4.Keep the pause, remove the sludge
  5. 5.Test it, then ask who it serves

From the comic

The default is selected. My arms have decided that inaction means everybody loves reminders.
