Choice architecture
Choice architecture is the practice of designing the context in which people make decisions — the arrangement of options, the setting of defaults, the framing of information, and the sequencing of choices — in order to influence behavior without coercing it or altering economic incentives. Coined by Thaler and Sunstein, the term captures the insight that there is no such thing as a "neutral" presentation of choices: every menu, form, and interface is already shaping what people select, often by accident rather than design.
The field draws on incentive architecture and behavioral economics to construct environments where beneficial choices are the easy choices. Unlike command-and-control regulation, choice architecture preserves autonomy while restructuring the default effect and loss aversion that already drive human decision-making. The ethical boundary between legitimate choice architecture and manipulative "dark patterns" remains contested — and the distinction may be less stable than its proponents assume.
