You should evaluate information throughout the research process to ensure that the information you rely on to support your argument presents the clearest picture of a topic as possible. To learn about evaluating information throughout research process, check out our Evaluating Information guide.
Reference sources (the types of sources you typically use for background research) require slightly different methods for evaluating information.
In general, reference sources are just a starting point, so you don't need to worry as much about fact-checking every piece of information you find in a dictionary or encyclopedia. Your main goal in using reference sources is to help figure out where to go next, so focus more of your evaluation efforts on assessing the sources you consult once you have more background information.
However, there are still some things to consider when consulting any source:
Your goal for doing background research is to get facts and learn where to go next. Good reference sources will provide you with straightforward information and pathways to continue learning about your topic and related ideas. Some sources for doing background research may attempt to entertain or advocate on an issue, but any purpose besides providing accurate information should be secondary.
Every source is biased in some way. Choosing to provide information about a topic is a form of bias because the author has decided that the topic is worth providing information about. However, we should always seek to minimize bias in our research and in our own work.
When evaluating reference sources, look out for:
Accuracy of information can be difficult to judge if you are new to a topic. However, consider whether the source aligns with background knowledge you already have about the topic. If it doesn't, this could be a sign that the source is inaccurate, or you may need to search elsewhere to determine whether your previous understanding was wrong.
Logical fallacies are abuses of logic that lead to unwarranted or inaccurate conclusions. Purdue's Online Writing Lab (OWL) provides a great overview of different types of logical fallacies.
For background research, it's best to have the most updated information on a topic because this information tends to be more accurate and it will also give you the most useful options to explore further.
As you do background research, pause regularly to consider whether the information you're exploring is relevant to your research. It's totally fine (and encouraged) to let the information you find lead you to other ideas you hadn't considered before, but it will help you work more effectively and efficiently to keep your overall goals in mind throughout the process.
Most Wikipedia articles can be edited by anyone, which means there's an inherent risk that that information might be inaccurate or biased. However, the crowd-sourced nature of Wikipedia means that errors are typically corrected relatively quickly. That said, here are some general tips for evaluating the credibility of Wikipedia articles:
