Research on Your Own

Information Savvy!

Many websites, such as Wikipedia, can be great resources to quickly get oriented on a subject before conducting more in depth research. However, anyone in the world can create and maintain a website or write a seemingly legitimate article and may, intentionally or unintentionally, publish false or “misinformation.” When reviewing information on the Internet, you should always consider the ABC’s:

  • Accuracy. Is the information accurate? Can you confirm the same information using other resources published by a different author or organization?
  • Author. Who composed the information? Can you easily identify the author and contact the author or website publisher?
  • Bias. What bias might the author or author organization have?
  • Credibility. What is the author’s or author organization’s credentials for publishing the information? What expertise, experience, or education does the author have in this area that makes him or her qualified to write on the subject matter?
  • Currency. When was the web page last updated? Is it possible the information might have changed since this web page was last published?
  • Critical eye! Remember to always use your discretion and critical eye to determine whether information you find on the web (or even in books and news sources!) is trustworthy. Putting websites to the ABC test will get you started in developing a strong critical eye.
