Sludge theory

Last updated

Sludge in behavioral economics refers to any form of design, administrative, or policy-related friction that systematically impedes individuals' actions or decisions. [1] [2] [3] It encompasses a range of frictions such as complex forms, hidden fees, and manipulative defaults that increase the effort, time, or cost required to make a choice, often benefiting the designer at the expense of the user's interest. [1] [4] [5]

The concept of sludge highlights the importance of transparent and user-friendly design in promoting welfare, efficiency, and equity in decision-making processes. [1]

Sludge was popularized by behavioral economist Richard Thaler and legal scholar Cass Sunstein. They introduced it as the "dark cousin" of nudging in their book Nudge: Improving Decisions About Health, Wealth, and Happiness.
