Criticism of science
Criticism of science addresses problems within science in order to improve science as a whole and its role in society. Criticisms come from philosophy, from social movements like feminism, and from within science itself.
The emerging field of metascience seeks to increase the quality of and efficiency of scientific research by improving the scientific process.
Philosophical critiques
advanced the idea of epistemological anarchism, which holds that there are no useful and exception-free methodological rules governing the progress of science or the growth of knowledge, and that the idea that science can or should operate according to universal and fixed rules is unrealistic, pernicious and detrimental to science itself. Feyerabend advocates a democratic society where science is treated as equal to other ideologies or social institutions such as religion, and education, or magic and mythology, and considers the dominance of science in society authoritarian and unjustified. He also contended that the demarcation problem of distinguishing science from pseudoscience on objective grounds is not possible and thus fatal to the notion of science running according to fixed, universal rules.Feyerabend also criticized science for not having evidence for its own philosophical precepts. Particularly the notion of Uniformity of Law and the Uniformity of Process across time and space, or Uniformitarianism in short, as noted by Stephen Jay Gould. "We have to realize that a unified theory of the physical world simply does not exist" says Feyerabend, "We have theories that work in restricted regions, we have purely formal attempts to condense them into a single formula, we have lots of unfounded claims, phenomena that do not fit into the accepted framework are suppressed; in physics, which many scientists regard as the one really basic science, we have now at least three different points of view...without a promise of conceptual unification". In other words, science is begging the question when it presupposes that there is a universal truth with no proof thereof.
Historian Jacques Barzun termed science "a faith as fanatical as any in history" and warned against the use of scientific thought to suppress considerations of meaning as integral to human existence.
Sociologist Stanley Aronowitz scrutinized science for operating with the presumption that the only acceptable criticisms of science are those conducted within the methodological framework that science has set up for itself. That science insists that only those who have been inducted into its community, through means of training and credentials, are qualified to make these criticisms. Aronowitz also alleged that while scientists consider it absurd that Fundamentalist Christianity uses biblical references to bolster their claim that the Bible is true, scientists pull the same tactic by using the tools of science to settle disputes concerning its own validity.
New-age writer Alan Watts criticized science for operating under a materialist model of the world that he posited is simply a modified version of the Abrahamic worldview, that "the universe is constructed and maintained by a Lawmaker". Watts asserts that during the rise of secularism through the 18th to 20th century when scientific philosophers got rid of the notion of a lawmaker they kept the notion of law, and that the idea that the world is a material machine run by law is a presumption just as unscientific as religious doctrines that affirm it is a material machine made and run by a lawmaker.
Epistemology
David Parkin compared the epistemological stance of science to that of divination. He suggested that, to the degree that divination is an epistemologically specific means of gaining insight into a given question, science itself can be considered a form of divination that is framed from a Western view of the nature of knowledge.Author and Episkopos of Discordianism Robert Anton Wilson stresses that the instruments used in scientific investigation produce meaningful answers relevant only to the instrument, and that there is no objective vantage point from which science could verify its findings since all findings are relative to begin with.
Ethics
Several academics have offered critiques concerning ethics in science. In Science and Ethics, for example, the professor of philosophy Bernard Rollin examines the relevance of ethics to science, and argues in favor of making education in ethics part and parcel of scientific training.Social science scholars, like social anthropologist Tim Ingold, and scholars from philosophy and the humanities, like critical theorist Adorno, have criticized modern science for subservience to economic and technological interests. A related criticism is the debate on positivism. While before the 19th century science was perceived to be in opposition to religion, in contemporary society science is often defined as the antithesis of the humanities and the arts.
Many thinkers, such as Carolyn Merchant, Theodor Adorno and E. F. Schumacher considered that the 17th century Scientific Revolution shifted science from a focus on understanding nature, or wisdom, to a focus on manipulating nature, i.e. power, and that science's emphasis on manipulating nature leads it inevitably to manipulate people, as well. Science's focus on quantitative measures has led to critiques that it is unable to recognize important qualitative aspects of the world.
Critiques from within science
is the use of scientific methodology to study science itself, with the goal of increasing the quality of research while reducing waste. Meta-research has identified methodological weaknesses in many areas of science. Critics argue that reforms are needed to address these weaknesses.Reproducibility
The social sciences, such as social psychology, have long suffered from the problem of their studies being largely not reproducible. Now, medicine has come under similar pressures. In a phenomenon known as the replication crisis, journals are less likely to publish straight replication studies so it may be difficult to disprove results. Another result of publication bias is the Proteus phenomenon: early attempts to replicate results tend to contradict them. However, there are claims that this bias may be beneficial, allowing accurate meta-analysis with fewer publications.Cognitive biases
Critics argue that the biggest bias within science is motivated reasoning, whereby scientists are more likely to accept evidence that supports their hypothesis and more likely to scrutinize findings that do not. Scientists do not practice pure induction but instead often come into science with preconceived ideas and often will, unconsciously or consciously, interpret observations to support their own hypotheses through confirmation bias. For example, scientists may re-run trials when they do not support a hypothesis but use results from the first trial when they do support their hypothesis. It is often argued that while each individual has cognitive biases, these biases are corrected for when scientific evidence converges. However, systematic issues in the publication system of academic journals can often compound these biases. Issues like publication bias, where studies with non-significant results are less likely to be published, and selective outcome reporting bias, where only the significant outcomes out of a variety of outcomes are likely to be published, are common within academic literature. These biases have widespread implications, such as the distortion of meta-analyses where only studies that include positive results are likely to be included. Statistical outcomes can be manipulated as well, for example large numbers of participants can be used and trials overpowered so that small difference cause significant effects or inclusion criteria can be changed to include those are most likely to respond to a treatment. Whether produced on purpose or not, all of these issues need to be taken into consideration within scientific research, and peer-reviewed published evidence should not be assumed to be outside of the realm of bias and error; some critics are now claiming that many results in scientific journals are false or exaggerated.Science has been criticized for being too conformist, and for becoming on average less disruptive.
Feminist critiques
Feminist scholars and women scientists such as Emily Martin, Evelyn Fox Keller, Ruth Hubbard, Londa Schiebinger and Bonnie Spanier have critiqued science because they believe it presents itself as objective and neutral while ignoring its inherent gender bias. They assert that gender bias exists in the language and practice of science, as well as in the expected appearance and social acceptance of who can be scientists within society.Sandra Harding says that the "moral and political insights of the women's movement have inspired social scientists and biologists to raise critical questions about the ways traditional researchers have explained gender, sex, and relations within and between the social and natural worlds." Anne Fausto-Sterling is a prominent example of this kind of feminist work within biological science. Some feminists, such as Ruth Hubbard and Evelyn Fox Keller, criticize traditional scientific discourse as being historically biased towards a male perspective. A part of the feminist research agenda is the examination of the ways in which power inequities are created and/or reinforced in scientific and academic institutions.
Other feminist scholars, such as Ann Hibner Koblitz, Lenore Blum, Mary Gray, Mary Beth Ruskai, and Pnina Abir-Am and Dorinda Outram, have criticized some gender and science theories for ignoring the diverse nature of scientific research and the tremendous variation in women's experiences in different cultures and historical periods. For example, the first generation of women to receive advanced university degrees in Europe were almost entirely in the natural sciences and medicine—in part because those fields at the time were much more welcoming of women than were the humanities. Koblitz and others who are interested in increasing the number of women in science have expressed concern that some of the statements by feminist critics of science could undermine those efforts, notably the following assertion by Keller:
