Today, most scientists and technologists are full-time professionals working for government, industry or universities. To get to these positions, they first have to undergo a long period of study and apprenticeship. To obtain a research post with some degree of authority and influence in a field, the researcher must proceed successfully through high school, university, PhD studies and often postdoctoral employment. The employment situation and the training to get there have a big impact on the sort of work the researchers do.

Most scientific training promotes conformity to standard scientific ideas and methods. In school and university, students are seldom encouraged to question conventional ideas such as cell structure, quantum theory or bridge design. Most science teachers simply teach “the facts,” including a set of methods for solving standard problems. They might want in principle to foster a more questioning approach, but in practice the syllabus is usually so filled with facts and skills that there is little time to do so. Students who are good at solving complex problems of the standard type — whether this is calculus or chemical analysis — are given the greatest encouragement through the system of assignments, examinations and grades. Those who develop their own methods, or who question the point of the exercises, are seldom favoured, unless they are also extremely good at the standard approaches.

By the time students are ready to begin their research apprenticeship, they have imbibed the current scientific world view. Research then involves a certain breaking down of the textbook picture of science, exploring areas where answers are less predictable and encouraging limited challenges to orthodoxy.

Although scientific training promotes conventional orientations to science, a few individuals come through their education with unorthodox perspectives. However, it is most difficult to develop a career at variance with standard views, because there are few jobs that allow this. Most jobs in government and industry are for applied research and development, or in pure research very obviously related to applied areas. Researchers in government agriculture departments might study transport of chemicals in soils. Chemical companies are likely to employ researchers to develop more effective pesticides. University researchers typically have more freedom, but they often rely on industry or government for grants to obtain equipment and technical support. Setting off in a research direction divergent from the standard one is not an easy road.

The military influence comes in at this level. The military provides jobs for a vast number of scientists and engineers, perhaps one quarter or even one half worldwide. Although a few military-funded scientists are able to do “pure research,” it is in areas of potential interest to the military, such as theoretical nuclear physics rather than sustainable agriculture.

The social location of most scientists and engineers who are not employed directly by the military is still quite convenient for military purposes. Most university and industry scientists and engineers are highly specialised in their training and work: they cannot readily switch from mechanical engineering to microbiology or vice versa. They are generally well-paid, see themselves as professionals and work among peers. As a group of workers who are mainly highly specialised, professionally oriented employees, most scientists and engineers are receptive to doing work where there is ample funding. They are trained and employed as technicians, namely to solve technical puzzles, and not to explore in depth who benefits and loses from their work. The funded research has to be in their field, so that their specialised skills can be brought to bear; it has to be sufficiently well funded, in keeping with their professional status; and it has to be recognised as acceptable by their peers.

The military can take advantage of this situation. Much military R&D requires highly specialised skills. The military has plenty of money to pay for research. Finally, military funding is acceptable to a good proportion of scientists and engineers. Most corporations are happy to have military funding, and so are most universities.[16] Most scientists and engineers are happy to accept whatever funding is available. There are also some who actively solicit military support, proposing projects that will appeal to military funders.[17]
