In the hierarchy of scientific principles, the scientific consensus – that is, the collective opinion and judgment of scientific experts in a particular field – is an important method to separate real scientific ideas and conclusions from pseudoscience, cargo cult science, and other beliefs.
I often discuss scientific theories which “are large bodies of work that are a culmination or a composite of the products of many contributors over time and are substantiated by vast bodies of converging evidence. They unify and synchronize the scientific community’s view and approach to a particular scientific field.”
A scientific theory is not a wild and arbitrary guess, but it is built upon a foundation of scientific knowledge that itself is based on evidence accumulated from data that resulted from scientific experimentation. A scientific theory is considered to be the highest scientific principle, something that is missed by many science deniers. In addition, a scientific consensus is formed by a similar method – the accumulation of evidence.
I have written frequently about the scientific consensus because it is one of the most powerful pieces of evidence in a discussion about critical scientific issues of our day – evolution, climate change, vaccines, GMOs, and many other areas of science.
This tome has one goal – to clarify our understanding of the scientific consensus, and how we arrive at it. Through this information, maybe we all can see the power of it in determining what is real science and what are policy and cultural debates.
But the most important thing is that the scientific consensus (and theories, for that matter) are not opinions. They aren’t random thoughts pulled out of the ether. Scientific consensus is based on overwhelming scientific evidence published in respected journals.Continue reading “Scientific consensus – collective opinion on vaccines, evolution, climate change”
