Goal: Find a source that was produced for the appropriate audience, and understand the bias or point of view presented.
Watch out for hidden agendas. For example, be skeptical of a web site that touts the benefits of an alternative medical treatment when it includes a link to buy the product. Although advertising in itself is fine, beware of deceptive advertising masquerading as fact, and of "click bait" that exists only to drive advertising.
For a political or controversial issue, make sure you get information from organizations or individuals on more than one side of the issue. Arguments can sound perfectly reasonable until you read the other side and see what they left out. Also, you need to find out the arguments of the opposing side if you are to effectively argue against them.
Strong, inflammatory, and emotional language are signs of bias. Look closely at the types of adjectives and verbs used, especially superlatives/absolutes (“always” and “never”), emotional/sweeping generalizations, and exaggeration. Examples: "This is obviously the most important idea ever conceived!" or "All teenagers are distracted drivers since they are always texting."
Bias is the tendency to favor a particular point of view and to present that view instead of other equally valid alternatives. When presented with new information that can be interpreted in several ways, individuals with different biases may present wildly different conclusions based on that information. Often, issues with multiple interpretations are presented as one-sided.
Here are a few examples of bias that you should look out for: (Source: Wikipedia pages)
If you find or believe there is a bias in argumentation from an individual or group, it does not necessarily mean that the argument is wrong. For instance, people often claim that there is a funding bias when a scientific study is funded by an industry group. That is not reason enough to dismiss the study, but potential bias is good to keep in mind when interpreting its conclusions and comparing them to the conclusions of other studies. To reject them out of hand would constitute a bias in itself. Ultimately, accepting or rejecting a conclusion should be based on the scientific evidence.
