The use of law as a tool for directed social change is widespread in all contemporary societies, but systematic procedures and understanding are lacking. Only a complex multivariable behavioral analysis can provide the knowledge necessary for wise policy recommendations. The task requires mixed teams of lawyers, social scientists, and policy analysts at various points in the social guidance cluster--the legislature, the executive, research organizations, and universities. It also calls for changes in the policymaking system to permit utilization of the work of such teams, through a broader, more systematic approach to policymaking in general. This, in turn, requires changes in higher education to provide (1) analytical and social science training in the law schools, and (2) special institutes at which interested lawyers, social scientists, and policy analysts acquire a grounding in each other's skills.
