Discussion of the need for policy sciences and for improving public policymaking systems. In the case of systems, one need is for intelligent mass participation in public policymaking. Among an array of innovative approaches: more policy research organizations--some working directly for the public, not just government; sabbaticals for elected politicians to broaden their understanding of political, social and technological trends; new legal-political arrangements to permit extensive social experimentation; and new uses for modern technology, such as analyses of controversial issues on TV and systematic opinion polling with the aid of computer home consoles. New training tools for this effort might include projects, policy games, and policy exploration programs on cable TV. 28 pp.
