Bias and Perspective Q&A

Q: What is bias?

A:  Bias is any judgment, argument, or conclusion that is not supported with evidence. Often bias is unintentional, sneaking in by way of human nature. When people feel strongly about a topic, they often think their opinions are facts when in actuality they are not. Sometimes bias is intentional. An author, company, or organization may want to promote or eliminate a certain opinion, product, or ideology so they manipulate the reader through word choice, tone, and omission (more below).

Q: What is the difference between bias and perspective? 

A: Bias is an opinion that is not supported with any facts or evidence, whereas perspective is an interpretive framework through which someone is analyzing an issue. Perspectives can be different, but they should be supported by factual evidence. 

Q: How can I tell if a source is biased?

A: Bias can be hard to spot. You usually won't be able to detect bias by just looking at the abstract - this is the kind of evaluation you will do as you read through and compare the sources you've collected. Even then, you often need to collect multiple sources on the same issue to determine whether bias is present. There are a few different things you can do to avoid bias:

Word Choice:

  • Look at the word choice used in the article: Does it seem over-the-top? Is it trying to evoke a certain emotion in the reader? Word choice that seems exaggerated or over dramatic may be a warning flag for bias. 


  • Look at the tone of the article: Does it seem aggressive? Accusatory? This could also mean bias is at hand. 


  • Has any information been purposefully omitted from the article? You may need more than one article on this topic to know for sure. Are they only presenting one side of the story? Are they blaming one party without backing it up with evidence? 


  • Look at the sources! If it's a scholarly article, they should cite their sources. If it is a newspaper, magazine, or website, look at where the author is getting their information within the article itself. Who did they cite? Who did they interview? Are they getting their information from multiple sources or just one? If the information is coming from a limited number of sources, there may be some risk of bias. 


  • Understand the purpose of the source. Ask yourself if the source you're analyzing has anything to gain from promoting one side of an issue over the other. Are they simply trying to inform you? Do they want to sell you something? Are they trying to spread a certain ideology? 


  • Look at the author of the source. Do they have credentials on this topic? Do they have anything to gain from promoting one side of an event over the other. Do they incorporate various perspectives in their article? 

WHAT is it - WHY should you believe it - WHY is it right for you now

Where to Find the Credibility Information for Sources


  • Database = on article page or link to a bio or description
  • Website = search with quotes like "New York Times" and look for  "About" or "Publishing Standards" or "Qualifications"
  • Wikipedia page = beware of any suspiciously positive or negative information



  • Book Itself = Front/back flap or pages
  • Website = of Author or Publisher
  • Wikipedia = beware suspicious negative or positive spin



  • "About" page = OR "Credentials," "Who We Are, "Mission, "Purpose"
  • Impossible to find = what are they hiding? Why? Why would you use it, then?
  • Click as many times into the information as you need to truly understand who is responsible for the information--sometimes it may be 5 consecutive clicks in or more



  • Web search = quotes around full name, e.g. "Junot Diaz." Interviews can work. Add inurl:edu if scholarly.
  • Impossible to find = Are they dead? Are they hiding?
