"Scientific dissent and public policy"
''EMBO Reports'', 14 (3): 231–235. In modern times, with the increased role of science on the society and the politicization of science, a new aspect gained prominence: effects of scientific dissent on public policies. Scientific dissent is distinct from

denialism In the psychology of human behavior, denialism is a person's choice to denial, deny reality as a way to avoid believing in a psychologically uncomfortable truth. Denialism is an essentially irrational action that withholds the validation of a h ...

Dissent as part of scientific inquiry

Miriam Solomon in her book ''Social Empiricism'' argues that scientific dissent is the normal state of

scientific inquiry Models of scientific inquiry have two functions: first, to provide a descriptive account of ''how'' scientific inquiry is carried out in practice, and second, to provide an explanatory account of ''why'' scientific inquiry succeeds as well as it ap ...

, rather than a conflict situation that needs resolution. She argues that disagreements of individual scientists about the proper direction of research are not cause for concern, because scientific rationality must be assessed at the level of the scientific community. As long as all theories being pursued yield some unique empirical successes, Solomon argues that their pursuit is worthwhile and even consistent with the common view that science aims at truth. In Solomon's view, competing scientific theories can even be inconsistent with one another while each containing some degree of truth. Empirical evidence may not be sufficient to distinguish between competing theories, and successful theories often have core assumptions that are incorrect.

Historical scientific dissent

A number of famous scientists have been sceptical of what were, or came to be, mainstream scientific positions. For example,

Ernst Mach Ernst Waldfried Josef Wenzel Mach ( ; ; 18 February 1838 – 19 February 1916) was an Austrian physicist and philosopher, who contributed to the understanding of the physics of shock waves. The ratio of the speed of a flow or object to that of ...

famously declared in 1897: "I don't believe that atoms exist!" Wilhelm Ostwald expressed a similar scepticism about atoms, but changed his mind in 1908. In the early 20th century,

Suppressed dissent

Scientific debate is a healthy and necessary part of science, but scientific debate may collide with power dynamics within the academic world.Delborne, J.A. (2016) "Suppression and Dissent in Science". In: Tracey Ann Bretag (Ed) ''Handbook of Academic Integrity'', 64: 943–956. Springer. . Suppression of legitimate scientific debate can be considered as a breach of academic integrity. Examples of suppression include journal editors rejecting a paper for political reasons prior to peer-review, refusing access to data for research which might draw negative conclusions about the safety of some commercial product, and putting pressure on a university to fire a dissenting researcher.

False scientific dissent

. In what is sometimes known as the " Galileo gambit", pseudoscientists will sometimes compare themselves to Galileo, arguing that opposition from established scientists is actually a point in favour of their ideas. Jean Paul Van Bendegem writes that "No doubt the most famous example of mistaken analogy is the abuse of Galileo Galilei's case resulting in his conviction by the Holy Inquisition. The basic strategy consists of equating Galileo with the poor astrologer or parapsychologist and equating the Inquisition with the scientific establishment."

Effect on modern public policies

Views which disagree with

may have an adverse effect on the perception of science by general public and affect decision making in various policies. When prominently promoted without due proportion, dissenting views can create an impression of uncertainty to laypeople. Common examples of such situation include global warming controversy and issues of

s. Therefore, scientists treat scientific dissent as problematic when it may have a significant impact on public and policy-making, and try to mitigate it.Aklin, M. and Urpelainen, J. (2014
"Perceptions of scientific dissent undermine public support for environmental policy"
''Environmental Science & Policy'', 38: 173–177. Inmaculada de Melo-Martín and Kristen Intemann criticize three major strategies in battling allegedly dangerous scientific dissent: masking the dissent, silencing the dissent, and discrediting the dissenters. Melo-Martin and Intermann argue that these strategies come from a misdiagnosis: the real problem is not dissent, but public scientific illiteracy. Rather than focusing on dissent, scientists must concentrate on educating the general public, so that people could make educated opinions and recognize false claims and invalid arguments. They further argue that silencing dissent rather than promoting literacy incurs the risk of undermining the public trust in science. Sheila Jasanoff, in the context of
