Q. How can I check for bias in the books, articles or web pages that I'm reading?

When you're researching a topic, you often want "just the facts," so that you can draw your own conclusions about what you're reading.  Scholarly articles are a good choice, since they are often written simply to report and discuss original research findings.    Or, web articles published by educational organizations, intended to teach or inform, can be helpful, too.

However, plenty of people (and organizations) publish with other intentions.  They may want to advocate for a cause or a political issue.  They may want to sell a product.  It doesn't necessarily mean that you can't use their information.  In fact, if you want to find opposing viewpoints or to gather examples of marketing or political strategies, etc.  these kinds of publications might be just what you need.  But, when you need unbiased information, they could lead you astray.  Even genAI tools can pick up biases from the materials they use to write responses. You need to be able to spot bias, so that you can decide whether a source is right for your project.

• If its purpose is to persuade, endorse, promote, market, sell or entertain.  If you're not sure, check the organization/publisher/magazine website for an "about" or "mission" link.  If the site has motives beyond simply teaching or informing, then you need to be on guard for bias and inaccuracies in any information that you find there.
   
• If it presents a one-sided view of a controversial issue, or the author dwells on his or her opinion without giving equal time to opposing viewpoints.
   
• If it uses negative language to describe opposing viewpoints, products, candidates, etc.
   

• If it's scholarly, it's probably a safe bet.   Objectivity is prized in scholarly literature...particularly in peer review.
   
• It remains neutral on controversial issues, giving equal time to each point of view.  An unbiased author will try to fairly represent conflicting ideas, without trying to convince you that one is right.
   
• If its purpose is to teach or inform or disseminate research, it's likely relatively safe from bias. 
  • On an organization's website, look for an "about" or "mission" link. 
  • In an ebook, look for an introduction, or go to the publisher's website. 
  • For an article, go to the journal, magazine or newspaper's website and look for an "about" link.
