Current policy analysis has proved less useful in improving public policy formation than policy scientists once argued it would. At least part of the reason for this lies in the fact that policy analysis has concentrated too narrowly on economic paradigms in teaching and practice, minimizing the evaluation of consequences outside that field. To be truly effective, policy analysis should have a multidisciplinary focus, combining insights from many social and natural sciences. Greater political science input at the level of teaching and practice can lead to a more holistic, and ultimately more useful, analytical science. Such an enterprise would be concerned with a greater range of problems and solutions and assessment criteria and would be more sensitive to the needs of elected officials and interest groups involved in the policy process.
