Bias, whether done intentionally or not, occurs when a statement reflects a partiality, preference, or prejudice for or against an object, person, place, or idea. Listed below are problems to look for when determining if the source is biased.
NOTE: The act of determining bias in scholarly research is also an act of constant self-reflection. Everyone has biases. Therefore, it is important that you minimize the influence of your own biases by approaching the assessment of another person's research introspectively and with a degree of self-awareness.

Web Content Requires Additional Methods of Evaluation
A report from the Stanford University Graduate School of Education found that students evaluating information that flows across social media channels or retrieved from online search engines like Google or Bing, have difficulty distinguishing advertisements from news articles or how to identity where the content came from.
In general, the principles that guide your evaluation of print materials are the same that apply to evaluating online resources. However, unlike print materials that have certain features that help determine their scholarly integrity, the interactive and multimedia dynamics of digital sources requires additional attention to the content in order to obtain confidence that what you are viewing is valid and credible.
