The Science and Public Policy Institute (SPPI) provides research and educational materials dedicated to sound public policy based on sound science. We support the advancement of sensible public policies rooted in rational science and economics.  Only through science and factual information, separating reality from rhetoric, can legislators develop beneficial policies without unintended consequences that might threaten the life, liberty, and prosperity of the citizenry roposals demanding prodigious economic or political sacrifices for the sake of negligible benefits should be rejected in favor of policies to address graver, more immediate concerns PPI meets its educational objectives through timely online publication of white papers, reprints, briefings, blog entries, news stories and other educational materials.
