Choice Overload: When More Options Produce Fewer Decisions

What is this page about?

An explainer of choice overload, the finding that too many options can reduce decisions and satisfaction, anchored in Iyengar and Lepper's 2000 jam study where a 6-variety display produced far more purchases than a 24-variety one. It reviews the contested evidence, including the Scheibehenne meta-analysis showing a near-zero average effect and Chernev's work specifying the conditions under which overload appears, plus the inverted-U relationship, the cognitive mechanisms, four case studies (jam, 401(k) participation, Netflix, medical decisions), and when more choice is genuinely better.
