    [ding Policy Analysis: The NSF Roleear public and private organizations commission or perform thou-policy-focused analyses in which issues of science and technologyally important. This blizzard of risk assessments, decision analy-the like plays an increasingly important role in the processes ofgoverning, and regulating our technological society. While they

    tire a few days or several years to perform, such analyses arey short-term. They must use available strategies, analytical tools,Ice to inform and enlighten the policy-making process.Df these analyses have been disappointing. Too often the bound-assumptions are not adequately defined and justified; scientific

    r uncertainties are inadequately characterized; issues of value arely delineated and may be confused with issues of fact; analyticals are inadequate; and virtues such as simplicity, robustness,and transparency are lost in a haze of technical verbiage.

    zing the quality of policy analysis that involves science andDry is the responsibility of many groups, both public and private.ional Science Foundation, charged with the support of basicin science and engineering, has a unique opportunity to contribute.support research, development, and selected demonstrationsbasic strategies, tools, and assumptions in science- and technolo-

    d policy analysis; encourage the development of mechanisms foral review and evaluation of analyses and analysis methods, both inst of quality control and in the expectation that we can learn fromrience; support selected "model" policy studies with substantiver engineering content which could serve as benchmarks againsty-to-day analyses could be measured; support policy studies ont problems that fall between the cracks of mission-agency agendas;graduate education in this field; and finally, encourage a modest)f basic research to be more responsive to policy-focused needs.ecently, NSF has supported some of these activities but has noten a broad program to support fundamental long-term improve-the field. Since the late 1970's NSF's policy resources have beenated in its Division of Policy Research and Analysis (PRA).rly in its early years, PRA devoted some of its resources to long-damental work. However, the provision of policy analysis supportIs federal agencies has always been part of its mission. In recenthas spent more and more of its resources on studies that areve to the immediate and, often, political needs of these agencies.nt months, PRA has moved aggressively to restructure its activi-as assumed a higher profile in servicing the needs of OSTP, OMB,d other federal agencies, doing some work in-house and obtainingitside assistance from groups such as consulting firms throughrdering agreements" rather than the traditional grant mechanism. ItIs a variety of longer term grant programs. It is not yet clear howive these will be, how much science and engineering they willor how closely they will be tied to federal agency agendas.veral reasons a different and more drastic reorientation of PRAe contemplated. NSF is not, and has never been, a good place for aoolicy analysis job shop. Despite possible political appeal, the long-,s of such work to the foundation, particularly to its reputation as a)nate and objective research organization, are considerable. NSFyve a far greater impact, and in a manner more consistent with itsal role, if steps were taken to substantially reduce its directnent in policy support for federal agencies and its efforts wereated on building a long-term substantive program designed tothe quality and fundamental capabilities of science- and technolo-ed policy analysis. The choice deserves careful reconsideration.{ANGER MORGAN, Head, Department of Engineering and Public-arnegie-Mellon University, Pittsburgh, Pennsylvania 15213
