In this blog post, we will examine the relationship between science and society, focusing on the issue of the value neutrality of science and technology and the social responsibility of scientists.
The Meaning of Value Neutrality and Discussions on Science
The term “value neutrality” refers to an approach in scientific research that focuses solely on objective facts and seeks to exclude subjective value judgments. In his work ‘Objectivity in the Social Sciences and Social Policy’, the German sociologist Max Weber criticized the tendency for individuals’ worldviews to permeate social science discourse. He argued that ethical value judgments belong to the realm of the philosophy of values and that it is inappropriate for such judgments to interfere with the methodology of the social sciences, which are a branch of the empirical sciences.
The concept of “value neutrality,” as used in the social sciences, is employed with a similar meaning in the fields of pure science and technology. This has served as the starting point for important debates surrounding the meaning of science in society. In science, value neutrality refers to the perspective that “scientific facts or technology itself are completely neutral and pure, possessing no social or political significance beyond the researcher’s intellectual curiosity.” In other words, it is the claim that science consists solely of objective facts and does not, in and of itself, confer any additional value on a subject.
In ancient and medieval times, attempts were made to explore nature based on pure human curiosity and to explain the world through thought experiments and abstract reasoning. However, these activities were closer to philosophy than to science in today’s strict sense. Since the modern era, as science has developed rapidly, science and the technology derived from it have been applied across all aspects of daily life and have begun to interact closely with society as a whole. Advances in science and technology have significantly improved the standards of social systems such as agriculture, industry, and medicine, and policies and institutions have evolved accordingly. In modern society, it has become difficult to view science and technology as completely unrelated to social values, and consequently, the question “Is science truly value-neutral?” has been raised in earnest. Furthermore, as discussions regarding the social responsibility of scientists became necessary, the value-neutrality of science was also reexamined. The following two cases are representative examples of this.
The first case is the development of the atomic bomb. Physicist Robert Oppenheimer oversaw the design and final assembly of the atomic bomb during World War II. Working in collaboration with General Leslie Groves, the military director of the “Manhattan Project,” he organized thousands of scientists and led the project. While it is easy to assume that Oppenheimer conducted this research against his will due to military pressure, in reality, he himself had wanted to become the project’s director, and many of the scientists involved also supported the development of the weapon and its use against Japan. At the time, Oppenheimer regarded his research as a significant scientific achievement, but he came to feel deep guilt after the horrors of Hiroshima and Nagasaki became known. Subsequently, he did not participate in the development of the hydrogen bomb and, concerned about the international nuclear arms race, took a stance opposing its development. If Oppenheimer had given deeper consideration to the social implications and ethical responsibilities of science and technology at an earlier stage, it is possible that the development of the atomic bomb might have taken a different course.
The second example involves the advanced science, technology, and chemical agents used during the Vietnam War. In the 1960s, at the height of the Vietnam War, the United States launched the “Igloo White Project.” This plan involved using high-speed aircraft to install acoustic and seismic sensors along the North Vietnamese Army’s main routes of movement. This equipment detected the subtle vibrations and sounds generated by the North Vietnamese Army’s movements and transmitted the information to a computer center, which was then used to rapidly dispatch bombers. In addition, the United States sprayed large quantities of the defoliant Agent Orange over key operational areas in Vietnam. This defoliant contained highly toxic dioxin, and its purpose was to kill off the forest and eliminate enemy hiding places. It is reported that more than 76 million liters of herbicide were sprayed, a significant portion of which was Agent Orange. Even after the war ended, this substance left local residents with serious long-term health effects, including cancer, congenital disorders, and neurological disorders. The use of such advanced science and technology in actual warfare highlights the negative aspects of modern scientific and technological development and prompts us to reconsider the social responsibility of scientists and the value neutrality of science. Did scientists anticipate that the results of their research would be used as weapons that threaten humanity? If they did not anticipate this, can they not be held accountable for the consequences?
The Debate on Scientists’ Social Responsibility and Value Neutrality
This is precisely why the value neutrality of science is such an important issue. Depending on how the nature of science is defined, the roles and responsibilities of the various actors in society differ. If science is viewed as value-neutral, the scientific community must maintain its independence from society and bears only the responsibility to ensure that its research does not embody specific values. Furthermore, it is not considered necessary to consider the impact on society or actively deliberate on ethical issues when setting research directions. In this scenario, ethical judgments and social responsibility are left to other members of society, such as ethicists, politicians, and citizens. In today’s reality, it is not uncommon for many scientists and engineers engaged in highly specialized and fragmented research to fail to deeply consider the social implications of their work. Unless faced with extreme situations such as war, they often do not seriously reflect on how their research might affect society or feel a sense of responsibility for it. If society accepts the value-neutrality of science as an absolute principle, there is a possibility that scientists lacking a sense of responsibility regarding the social impact of research and development could give rise to various value conflicts and ethical problems in future society.
Conversely, if science is viewed as not being value-neutral, it is understood that science and technology already embody specific values and social purposes from the very stage of setting research goals. Therefore, scientists conducting research are required to exercise sound value judgments and maintain an ethical stance. In particular, following the dropping of atomic bombs toward the end of World War II, many scientists became aware of their moral responsibility regarding their research and, based on this, have continued efforts to fulfill the social obligations entrusted to scientists by organizing various groups and conferences. The recognition that the actual and potential harms caused by advances in science and technology must be minimized has also gradually expanded; there are two representative examples illustrating this.
One of the leading organizations that rejects the notion of scientific value neutrality is the World Federation of Scientific Workers (WFSW). This organization was founded in London, England, in 1946 under the leadership of the British Association of Scientific Workers, and scientists and science and technology-related organizations from various countries around the world subsequently joined. In 1948, the WFSW adopted the “Scientists’ Charter,” which is still regarded today as a document that clearly illustrates the social responsibilities faced by scientists. The Charter emphasizes that “the profession of a scientist entails special responsibilities in addition to those borne by ordinary citizens,” and declares that “since scientists possess specialized knowledge that is not readily accessible to the general public, they must strive to ensure that such knowledge is used for the benefit of humanity.” This means that scientists must shoulder responsibilities toward humanity and society that go beyond their functional role of simply seeking truth.
To fulfill these responsibilities, the Charter proposes that scientists must make efforts in three areas. First is the responsibility toward “science.” The purpose of scientific research must be sound; scientists must resist the suppression or distortion of scientific knowledge and share their research findings with society.
Second is the responsibility toward “society.” Scientists are expected to consider how their field of research relates to economic, social, and political issues; to explore knowledge that can have a positive impact on society; and to strive to ensure that such knowledge is actually put to use. Third is the responsibility toward “the world.” This includes researching the causes of war while simultaneously opposing the use of their research to prepare for or propagate war.
Another representative example that challenges the value neutrality of science is the Pugwash Conferences on Science and World Affairs, an international movement of scientists opposed to the arms race. The Pugwash Conferences is an international organization of scientists focused on mitigating the arms race and achieving disarmament. This, too, is an example demonstrating that scientists fundamentally reevaluated their social responsibilities following World War II. The starting point for the Pugwash movement was the “Russell-Einstein Manifesto,” published in 1955. Bertrand Russell, Albert Einstein, and other eminent scholars appealed for scientists to come together—transcending their differing political stances—to discuss the dangers that the development of weapons of mass destruction posed to all of humanity. Consequently, in 1957, 22 scientists from around the world gathered in Pugwash, Canada, to hold the first conference, which came to be known as the “Pugwash Movement” after the name of the host town. At the first meeting, the prevention of nuclear war and the achievement of disarmament were set as core objectives. At subsequent meetings, various measures were continuously discussed to reduce the risks of the nuclear arms race, achieve a complete halt to nuclear testing, prevent the proliferation of nuclear weapons, and prevent international crises from escalating into nuclear war.
Can Science and Society Be Separated?
As we have seen, unlike in the past when science remained within the realm of philosophical thought, in modern society—where science and technology transform society as a whole—it is difficult to completely separate science from society. Since scientists who develop science and technology are also human beings living within society, their research inevitably reflects, to some extent, social values and the demands of the times.
Those who advocate for the value neutrality of science argue that “the earliest science originated from the pure curiosity of scientists.” On the other hand, those who oppose value neutrality contend that science and technology—which have dual aspects—were not initially developed for the public good only to be later corrupted by human selfishness; rather, in many cases, research began from the outset within the context of the needs and interests of state power or large corporations. In other words, since scientific research itself is conducted under the influence of massive social interests, capital, and policy, the values of science and society are inextricably linked.
Nevertheless, the debate over the value neutrality of science continues to this day. Recently, with the rapid advancement of new scientific and technological fields such as artificial intelligence, gene editing, synthetic biology, and autonomous weapon systems, interest in the social responsibility of scientists has grown even further. These discussions are significant for examining science from social and philosophical perspectives and for gaining a more concrete understanding of the intersection between science and society. Moving forward, before new scientific and technological advancements—including artificial intelligence and human genetic technologies—are fully implemented in society, it will be necessary to conduct thorough social and philosophical discussions regarding the value neutrality of science and the social responsibility of scientists.
