Sometimes entire fields are shaped by military priorities. An obvious example is nuclear physics, which has received heavy military funding and provided jobs for many researchers. Furthermore, in several countries governments pursued nuclear power programmes as a means of keeping open the option of acquiring nuclear weapons or (in the US “Atoms for Peace” programme) to reposition nuclear technology as “peaceful.” The priority on nuclear weapons and nuclear power has meant that non-military nuclear physics, carried out in universities, has had a higher priority than otherwise would have been the case. Military researchers have been ready to take advantage of any advance from university research. Without the military and commercial interest in nuclear technology, it is likely that other branches of physics such as solar physics would have received greater attention.
Microelectronics and computing are other fields that were, for many years, driven by military applications.[4] For example, the development of sophisticated nuclear weapons makes heavy demands on computer power. In the early decades of nuclear weapons, the US nuclear weapons design laboratories — Lawrence Livermore National Laboratory and Los Alamos National Laboratory — worked closely with computer manufacturers to develop machines serving their particular requirements for high-speed numerical computation, and in some cases purchased a large proportion of the resulting production runs. Some of the choices in the architecture of supercomputers consequently reflect military influences.[5]
Since the development of computers, the field of numerical analysis — which, in part, deals with ways to solve problems using computers — has dramatically expanded, and there are areas of pure mathematics that take up esoteric questions related to numerical analysis. Thus, the development of computers has influenced the research priorities of some mathematicians; in turn, pure mathematics research relating to numerical analysis occasionally leads to results that have practical value.
In this way, possible applications influence the direction of research. Military applications are one such application. Thus, although most pure mathematicians do not have military applications directly in mind, their work may be oriented in directions making it more likely to serve military purposes.
The large amount of US military funding for electronics in the years after World War II actually led to few transfers for civilian uses.[6] In recent years, commercial uses have played a larger role in microelectronics research. Commercialisation is even a goal for some military-funded research.[7]
In the case of the insecticide DDT during World War II, military applications served to accelerate research in one particular direction. As a result of the emphasis on short-term control of insect pests by chemicals to support the war effort, research into biological control of pests declined rapidly, institutionalising a pattern that has persisted long after commercial interests became the primary influence on pesticide research.[8]
The social science field of communication studies in the United States was shaped by massive military funding and military agendas, especially in the early years 1945-1960. The military’s interest in the field derived from interest in psychological warfare which — in military terms — included not just propaganda but also techniques such as deception, “dirty tricks,” assassination, and terrorism. This context was omitted from the academic face of communication studies. Leading researchers and research centres received massive military grants. Major military studies were often later published in academic forums, usually without acknowledgement of their link to the military. Communication research was oriented to the goals of domination and manipulation of mass audiences. The development and use of now-standard survey techniques also reflected military priorities.[9]
Similarly, research in educational technology in the US has been heavily funded by the military, with military priorities of developing man-machine systems. Douglas Noble argues that computers in classrooms and computer-related procedures are not neutral tools, but rather reflect military goals. For example, when educational institutions operate in terms of “instructional delivery systems,” this can be said to reflect a military interest in command and control.[10]
