How decision makers define state interests and formulate policies to deal with complex and technical issues can be a function of the manner in which the issues are represented by specialists to whom they turn for advice in the face of uncertainty. The contributors to this issue examine the role that networks of knowledge-based experts—epistemic communities—play in articulating the cause-and-effect relationships of complex problems, helping states identify their interests, framing the issues for collective debate, proposing specific policies, and identifying salient points for negotiation. Their analyses demonstrate that control over knowledge and information is an important dimension of power and that the diffusion of new ideas and data can lead to new patterns of behavior and prove to be an important determinant of international policy coordination.

4. The term “epistemic communities” has been defined or used in a variety of ways, most frequently to refer to scientific communities. In this volume, we stress that epistemic communities need not be made up of natural scientists or of professionals applying the same methodology that natural scientists do. Moreover, when referring to epistemic communities consisting primarily of natural scientists, we adopt a stricter definition than do, for example, Holzner and Marx, who use the term “epistemic community” in reference to a shared faith in the scientific method as a way of generating truth. This ignores that such faith can still bond together people with diverse interpretations of ambiguous data. By our definition, what bonds members of an epistemic community is their shared belief or faith in the verity and the applicability of particular forms of knowledge or specific truths. Our notion of “epistemic community” somewhat resembles Fleck's notion of a “thought collective”—a sociological group with a common style of thinking. It also somewhat resembles Kuhn's broader sociological definition of a paradigm, which is “an entire constellation of beliefs, values, techniques, and so on shared by members of a given community” and which governs “not a subject matter but a group of practitioners.” See Holzner, Burkhart and Marx, John H., Knowledge Application: The Knowledge System in Society (Boston: Allyn & Bacon, 1979), pp. 107–11;Google ScholarFleck, Ludwig, Genesis and Development of a Scientific Fact (Chicago: University of Chicago Press, 1979; translated from the 1935 edition printed in German)Google Scholar; and Kuhn, Thomas S., The Structure of Scientific Revolutions, 2d ed.

5. Other characteristics of epistemic communities that were mentioned or discussed during the preparation of this volume included the following: members of an epistemic community share intersubjective understandings; have a shared way of knowing; have shared patterns of reasoning; have a policy project drawing on shared values, shared causal beliefs, and the use of shared discursive practices; and have a shared commitment to the application and production of knowledge. These phrases were not incorporated in the formal definition listed here; they are simply provided to evoke additional notions that are associated with epistemic communities. a For examples, See Gilpin, Robert, War and Change in World Politics (Cambridge: Cambridge University Press, 1981)CrossRefGoogle Scholar; Krasner, Stephen D., Structural Conflict (Berkeley: University of California Press, 1985)Google Scholar; and Waltz, Kenneth N., Theory of International Politics (Reading, Mass.: Addison-Wesley, 1979).Google Scholar b For examples, See Cardoso, Fernando Henrique and Faletto, Enzo, Dependency and Development in Latin America (Berkeley: University of California Press, 1979)Google Scholar; Evans, Peter, Dependent Development (Princeton, N.J.: Princeton University Press, 1979)Google Scholar; Evans, Peter, “Declining Hegemony and Assertive Industrialization,” International Organization 43 (Spring 1989), pp. 207–38;CrossRefGoogle ScholarGaltung, Johan, The True Worlds (New York: Free Press, 1984)Google Scholar; and Wallerstein, Immanuel, The Capitalist World Economy (Cambridge: Cambridge University Press, 1979).Google Scholar c For examples, See Derian, James Der and Shapiro, Michael J., eds., International/Intertextual Relations (Lexington, Mass.: Lexington Books, 1989)Google Scholar; and Ashley, Richard K. and Walker, R.

6. A number of earlier studies focusing on the interplay between expertise, technical issues, consensual knowledge, and state power have considered the role of epistemic-like communities in the decision-making process. At the level of international organizations, such studies have been undertaken with regard to wide variety of issue-areas and have demonstrated that webs of nonstate actors provided information and were involved in the shaping of agendas and the defining of state interests. While all of these studies cannot be listed here, a few examples show the range of areas analyzed: Russell, Robert W., “Transgovernmental Interaction in the International Monetary System, 1960–1972,” International Organization 27 (Autumn 1973), pp. 431–64;CrossRefGoogle ScholarAscher, William, “New Development Approaches and the Adaptability of International Agencies: The Case of the World Bank,” International Organization 37 (Summer 1983), pp. 415–39;CrossRefGoogle ScholarCrane, Barbara B. and Finkle, Jason L., “Population Policy and World Politics,” paper presented at the Fourteenth World Congress of the International Political Science Association, Washington, D.C., 28 08 to 1 09 1988Google Scholar; Haas, Peter M., Saving the Mediterranean: The Politics of International Environmental Protection (New York: Columbia University Press, 1990)Google Scholar; Johnson, Barbara, “Technocrats and the Management of International Fisheries,” International Organization 29 (Summer 1975), pp. 745–70;CrossRefGoogle Scholar and Wooster, Warren S., “Interactions Between Intergovernmental and Scientific Organizations in Marine Affairs,” International Organization 27 (Winter 1973), pp. 103–13CrossRefGoogle Scholar. For examples of studies in comparative politics that discuss the role of epistemic-like communities in the development and enforcement of common policies, See Weir, Margaret and Skocpol, Theda, “State Structures and the Possibilities for ‘Keynesian’ Responses to the Great Depression in Sweden, Britain, and the United States,” in Evans, Rueschemeyer, and Skocpol, Bringing the State Back In, pp. 107–68;Google ScholarHall, Peter A., Governing the Economy (Cambridge: Polity Press, 1986), pp. 275 ff.;Google Scholar and King, Anthony, “Ideas, Institutions, and Policies of Governments: A Comparative Analysis” (in 3 parts), British Journal of Political Science 3 (07 and 10 1973), pp. 291–313 and 409–23CrossRefGoogle Scholar. With respect to policy coordination, it is worth stressing that even if actors believe that their common understandings will contribute to enhancing the collective good, serious unanticipated consequences are possible; See Evera, Stephen Van, “Cult of the Offensive and the Origins of the First World War,” International Security 9 (Summer 1984), pp. 58–107CrossRefGoogle Scholar.

7. While the transfer of authority to the sphere of the secular and the rational can be traced back to the eighteenth century and the granting of Noblesse de la Robe in France, the integration of scientists and engineers into a new rationalized corporate structure really began with the second industrial revolution of the 1880s.

13. Jawaharlal Nehru, arguing that less developed countries must also turn toward science, offered the following rationale: “It is science alone that can solve the problems of hunger and poverty, of insanitation and illiteracy, of superstition and deadening custom and tradition, of vast resources running to waste, of a rich country inhabited by starving people…. Who indeed could afford to ignore science today? At every turn we have to seek its aid….

Based on his survey of 75 percent of the UN's professional staff, Mango concluded that about 4,000 served key functions “in all areas of human endeavor from peace and disarmament to health, nutrition, industry, communications, and the environment.” Thus, for the full 100 percent of the staff, the figure may have reached 5,000.
20. The percentage of the UN budget allocated for specialized agencies steadily rose from 45.1 percent in 1950 to 60.5 percent in 1985. With the adoption of the Kaasebaum amendment, the percentage has remained at the 1985 level. Two specialized areas involving science and technology—that of food and agriculture and that of health—have come to control over 25 percent of the resources of the UN system. See UN document nos.

39. According to the definition of epistemic communities employed in this volume, community members have intersubjective, internally defined validity tests. This contrasts with Ernst Haas's usage of the concept of epistemic communities, in which he explicitly mentions that such communities “profess beliefs in extracommunity reality tests.” See Haas, Ernst B., When Knowledge Is Power (Berkeley: University of California Press, 1990), p. 41Google Scholar. Although there are other differences between his and our usage, they are fairly minor. I believe that this particular difference in emphasis on intracommunity versus extracommunity truth tests springs primarily from differing overarching historical visions. Ernst Haas seeks to demonstrate the evolution of rationality over time, possibly through the gradual intercession of epistemic communities into collective decision making. For such a normative claim to be sustained, the epistemic community must share a common basis for validation of its understanding with the broader policy community. Conversely, I am much more skeptical about such universal validity claims and am content to settle for the less ambitious internal truth tests. While in most cases members outside the epistemic community may concur that validity claims exist, it is less clear that they would be able to identify or evaluate them.
40. According to A. M. Carr-Saunders, “What we now call a profession emerges when a number of persons are found to be practicing a definite technique founded upon specialized training.” Carr-Saunders's classic formulation is cited by Vollmer, Howard M. and Mills, Donald L. in Professionalization (Englewood Cliffs, N.J.: Prentice-Hall, 1966), p. 3Google Scholar. Subsequent sociologists have formulated a fuller definition that includes a reputation for authority, society's sanction, barriers to entry, a regulative code of conduct, and a service orientation.
