Gewirtzman — Volume 63, Issue 2

Federalism has long been celebrated as a structure enabling state policy experimentation and innovation, yet constitutional scholarship remains surprisingly uninterested in the mechanics of experimental federalism. Gewirtzman applies complex systems theory to examine how decentralized systems innovate effectively. The article argues that traditional federalism scholarship has focused excessively on vertical relationships between federal and state governments, preoccupied with debates over states' rights versus federal power, and sidelined the practical question of how experimental federalism actually functions. Gewirtzman uses complex systems analysis to identify traits enabling decentralized systems to innovate: systems acquire more information when multiple actors simultaneously try different policy approaches; federal structures process information faster and offer conclusions more accurate than centralized experiments; federalism contains policy failure risks to individual states rather than imposing costs nationwide. When federal action creates policy vacuums, state experimentation becomes the only available solution for solving difficult social problems. The article explores how states are steadily expanding experimental spheres into areas with federal authority—immigration and medical marijuana—as political gridlock in Washington removes threats of federal preemption. Gewirtzman proposes a framework for understanding how experimental federalism works, identifying traits allowing decentralized systems to innovate effectively, and recommending constitutional changes that would help current federalism approach its experimental potential regardless of federal–state budget constraints or political climate shifts.
