Credibility is defined as the quality or power of inspiring belief. Credible sources, therefore, must be reliable sources that provide information that one can believe to be true. It is important to use credible sources in an academic research paper because your audience will expect you to have backed up your assertions with credible evidence.
Since credibility and reliability seem to have somewhat similar meanings finding the difference between reliability and credibility can be a little hard. When we speak of people, law, and even different sources of information, we use the terms reliable and credible.eliability, on the other hand, refers to relying on someone or something or being able to have trust and faith. It is true that the two terms are similar to a certain extent, but they are not synonymous. This article attempts to clarify the difference between the two words.
