U.S. Supreme Court Justice Louis Brandeis, in a 1932 opinion, wrote that a state could be a “laboratory” for policy, and “try novel social and economic experiments” on its own. We have since turned those words into today’s common political phrase that the 50 U.S. states are “laboratories of democracy.”
Some of these policy experiments move states to the right, politically, and others move states to the left. Now a new study conducted by MIT political scientists shows for the first time the modern political trajectory of all 50 U.S. states, since 1936, by examining their laws in relation to nearly 150 policy issues.
