Scientific credibility has been defined as the extent to which science in general is recognized as a source of reliable information about the world. The term has also been applied more narrowly, as an assessment of the credibility of the work of an individual scientist or a field of research. Here, the phrase refers to how closely the work in question adheres to scientific principles, such as the
scientific method. The method most commonly used to assess the quality of science is
peer review and then publication as part of the
scientific literature. Other approaches include the collaborative assessment of a topic by a group of experts, this process can produce reviews such as those published by the
Cochrane Collaboration, or the
Intergovernmental Panel on Climate Change. The 2008 credibility article written by Peter Alagona highlights that, "In environmental science, credibility is one of the most referenced yet the least comprehended concepts." This lack of understanding is due to the public often confusing credibility with trust because of shared characteristics, such as reliability and dependability. To be credible in the scientific field, researchers are to demonstrate
expertise, reliability and objectivity, through methods such as peer and systematic review, and
experimental studies. Alagona states that "the credibility of scientific research shapes the public's trust and influence policies." Therefore, scientific credibility means that when research is seen as trustworthy, it can shape various rules and regulations. This reinforces the public's trust, belief, and acceptance, as these guidelines are based on credible scientific findings. The general public can give a great deal of weight to perceptions of scientific authority in their decisions on controversial issues that involve scientific research, such as
biotechnology. However, both the credibility and authority of science is questioned by groups with non-mainstream views, such as some advocates of
alternative medicine, or those who dispute the
scientific consensus on a topic, such as denialists of
AIDS.
Political endorsements can reduce non-
partisan scientific credibility. == In medicine ==
