Now that you have found your sources, you must evaluate them. Evaluating sources becomes a major component of researching because the materials chosen will reflect upon your reputation. Aside from being able to find informative sources, a good researcher is also able to quickly assess the credibility of information. Through practice, this skill will come.
When setting out to write a research paper, there is a vast pool of information available, including books, newspapers, periodicals, reference works, and government documents. Included in this can be your own empirical data, obtained in interviews and surveys, but you will probably not need to use it all. As important as it is to be able to find sources specific to your topic, it is equally vital to be able to correctly assess each source’s credibility — that is, how trustworthy, accurate, and verifiable the sources are. Due to the vast amount of information available on the Internet, it presents an especially interesting challenge in determining the credibility of sources. However, even when evaluating print sources, the same criticism should be maintained.
You must also be aware of the author’s possible bias. Even the most credible sources may exhibit forms of bias, as most authors’ past experiences will come into play. Bias is most likely to occur in controversial topics such as politics or religion, but is still likely to be present whenever an opinion is voiced. The author’s beliefs and experiences can thus affect the objectivity of the text. Another case may be when the author or publisher has ties to a special interest group that may allow him or her to see only one side of the issue. Lastly, make sure to evaluate how fairly the author treats the opposing viewpoints. Complete objectivity is very difficult to attain in writing, but try to find sources that are not incredibly subjective. Nonetheless, the most important thing is simply to be aware of possible biases so that you are not misled.
Here are four approaches to assessing the credibility of the sources you find.
