Scrutinizing the multifaceted relationship between the history of science and the political, economic and cultural transformations of the 1970s, while acknowledging that Cold War [social] science' has proven to be a fruitful heuristic concept, the paper asks if- in a period decreasing confrontation -there was also a detente [social] science'? First, it presents a short overview of the most significant transformations of the 1970s and sketches if and to what extent developments in the realm of science influenced them or even brought them about. Secondly, the perspective will be turned around. After developing the concept of Cold War Science in greater detail, the paper asks whether the changes of the 1970s influenced the development of the natural and social sciences. In particular, it analyzes their influence on the conceptions of knowledge and expertise that have been described as constitutive elements of Cold War Science. In conclusion, it tries to assess if these changes amount to anything that might be labelled fruitfully as detente science.
