There appears to be a widespread belief that the social sciences during the 1950s and 1960s can be characterized by an almost unquestioned faith in a positivist philosophy of science. In contrast, the article shows that even within the narrower segment of Cold War social science, positivism was not an unquestioned doctrine blindly followed by everybody, but that quite divergent views coexisted. The article analyses two ‘techniques of prospection’, the Delphi technique and political gaming, from the perspective of a comprehensive set of ideas attributed to ‘positivism’. Both techniques were developed in the early 1950s by researchers at the RAND Corporation, a Californian think tank with tight relations to the US Air Force. Despite the closeness of origin, the two techniques show considerable differences in their basic epistemologies. The article thus concludes that more important than positivism in uniting US Cold War social science was the shared sense of urgency and of the potential of social science to put decision-making in foreign policy on a rational basis. In this sense, as far as the Cold War social sciences were of a piece, they were made so by the sense of danger and urgency of action evoked by the image of the Iron Curtain.

The bi-polar confrontation between the Soviet Union and the USA involved many leading game theorists from both sides of the Iron Curtain: Oskar Morgenstern, John von Neumann, Michael Intriligator, John Nash, Thomas Schelling and Steven Brams from the United States and Nikolay Vorob’ev, Leon A. Petrosyan, Elena B. Yanovskaya and Olga N. Bondareva from the Soviet Union. The formalization of game theory (GT) took place prior to the Cold War but the geopolitical confrontation hastened and shaped its evolution. In our article we outline four similarities and differences between Western GT and Soviet GT: 1) the Iron Curtain resulted in a lagged evolution of GT in the Soviet Union; 2) Soviet GT focused more on operations research and issues of centralized planning; 3) the contemporary Western view on Soviet GT was biased and Soviet contributions, including works on dynamic stability, non-emptiness of the core and many refinements, suggest that Soviet GT was able to catch up to the Western level relatively fast; 4) international conferences, including Vilnius, 1971, fostered interaction between Soviet game theorists and their Western colleagues. In general, we consider the Cold War to be a positive environment for GT in the West and in the Soviet Union.

An Area Studies Division was created at the 6^th Section of the École Pratique des Hautes Études (Paris) in the mid-1950s. It was devoted to several world regions, including the USSR and eastern Europe. This article investigates the links between its institutionalization and the international scientific and financial transfers underpinning it: the transatlantic support granted to the nascent division by the Rockefeller and Ford foundations and the academic cooperation programme that it launched with eastern Europe. The Russian, Soviet and East European programme served, thus, as an East/West interface and a platform for broader intellectual exchanges. Local French scientific, academic and political rationales favoured the specific pathways it took. The article also shows that the EPHE 6^th Section was discreetly linked with American players in Cold War intellectual warfare whose forms of action gradually changed in the context of the thaw. In particular, it had connections with the Congress for Cultural Freedom. These collusions attest to the entanglement of scientific and political issues, their intricacies increasing when external factors compounded domestic ones.
