Credibility of the source of information should depend on the information itself and not the opinion of whoever the author is that wrote the article. This is a form of impartiality. The author should only state facts. For example, if discussing a particular type of medicine, it should be clear of the author’s connection. Is he/she selling the product or promoting it? The writing style and tone is another way to form credibility and validity of sources of information. You should determine whether the tone is professional or not. If it is indeed professional and the tone is for the targeted audience then more than likely the source of information is credible. Some examples
