Choice Architecture: Designing Decisions for Impact
When Brian Wansink rearranged a school cafeteria, putting fruit at eye level and making desserts harder to reach, fruit consumption increased significantly.
Page Summary
An explainer of choice architecture, the practice of designing how options are presented to influence decisions without restricting freedom, opening with Thaler and Wansink's cafeteria experiment where rearranging food placement raised fruit consumption by up to 25%. It contrasts nudges with mandates, covers the cognitive foundations (dual-process theory, default effects, present bias, social norms), four applied case studies (organ-donation defaults, Save More Tomorrow, OPOWER energy norms, tax-compliance social proof), the empirical evidence, and the ethical critiques about manipulation and autonomy.

2 corrections applied: In Nudge the anecdote involves a food-services director named Carolyn, unrelated to Thaler; 'Caroline Thaler' is unverified. | The cafeteria placement research was conducted by Brian Wansink (with David Just and collaborators); there is no 'Carolyn Wansink'.
Beforea school district administrator named Caroline Thaler posed a problem to the economist Richard Thaler... Thaler and his collaborator Carolyn Wansink conducted what became one of the most-cited demonstrations
Aftera school food-services director named Carolyn posed a problem to the economist Richard Thaler... Thaler and the researcher Brian Wansink conducted what became one of the most-cited demonstrations
Why: Corrected two unverified names: the anecdote's food-services director is unnamed (referred to only as Carolyn) in Nudge, not a school district administrator named Caroline Thaler; and the cafeteria placement research was conducted by Brian Wansink, not an unverified Carolyn Wansink. Verified already live on the article; also confirmed no leftover instances in faq, excerpt, meta_description, or seo_keywords.
