Developing and supporting a scientific consensus

In my writing, I often refer to the scientific consensus, which is the collective opinion and judgement of scientists in a particular field of study. This consensus implies general agreement, though disagreement is limited and generally insignificant.

The major difference between a scientific theory and a scientific consensus is that the theory is essentially fact. It is so predictive, it is supported by so much evidence, and it is so well accepted, it takes an almost ridiculous amount of data to refute it, though it is possible.

In the hierarchy of scientific principles, we often mention 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.

We want to focus on the scientific consensus, describing what it is. Take a deep breath, because this is a complicated one.

Judging the quality of science sources

Recently, I wrote articles on skepticism and debunking pseudoscience, both of which require large amounts of evidence. And of course, a true scientific skeptic needs to judge the quality of evidence, because individuals who push science denialism often cherry pick seemingly high quality science to support their beliefs.

A good scientific skeptic needs to decipher the science (or pseudoscience) in popular news articles, for example, to determine its validity. We should be critical, if not skeptical, of what is written in these articles to ascertain what is or is not factually scientific. We even need to determine the quality of science from the best to the weakest, so that we can determine the level of authority of the science before we pass it along to others.

With the social media, like Facebook and Twitter, which provides us with data that may not exceed a few words, then it’s even more imperative that we separate the absurd (bananas kill cancer) from the merely misinterpreted (egg yolks are just as bad as smoking).

Wikipedia is one place which can either be an outstanding resource for science or medicine, or it can just a horrible mess with citations to pseudoscience, junk medicine pushers. For example, Wikipedia’s article on Alzheimer’s disease is probably one of the best medical articles in the “encyclopedia”. It is laid out in a logical manner, with an excellent summary, a discussion of causes, pathophysiology, mechanisms, treatments, and other issues. It may not be at the level of a medical review meant for a medical student or researcher, but it would be a very good start for a scientifically inclined college researcher or someone who had a family who was afflicted with the disease.

Quality of science sources in Wikipedia and the news

Several weeks ago, I wrote an article on how to decipher the science (or pseudoscience) in popular news articles. It discusses how we should be critical, if not skeptical, of what is written in these articles to ascertain what is or is not factually scientific. We even need to determine the quality of science from the best to the weakest, so that we can determine the level of authority of the science before we pass it along to others. With the social media, like Facebook and Twitter, which provides us with data that may not exceed a few words, then it’s even more imperative that we separate the absurd (bananas kill cancer) from the merely misinterpreted (egg yolks are just as bad as smoking).

Wikipedia is one place which can either be an outstanding resource for science or medicine, or it can just a horrible mess with citations to pseudoscience purveyors. For example, Wikipedia’s article on Alzheimer’s disease is probably one of the best medical articles on the “encyclopedia”. It is laid out in a logical manner, with an excellent summary, a discussion of causes, pathophysiology, mechanisms, treatments, and other issues. It may not be at the level of a medical review meant for a medical student or researcher, but it would be a very good start for a scientifically inclined college researcher or someone who had a family who was afflicted with the disease.
