Using SIFT to Evaluate Sources

SIFT is an acronym that can help you remember a quick method for doing an initial evaluation of a website or other source.  The sift method was created by Michael Caulfield.

  • What do you know about this source?
  • What do you know about the reputation of the source?
  • Do you know enough to decide whether or not to use it?
  • Don't share or use a website unless you know for sure what it is.

"F" stands for Find Trusted Coverage (or Find Better Coverage):

If the reputation of the source doesn't impress you but you are still interested in the information:

  • Try searching for a better source on the same topic.
  • Try looking at multiple sources on the same topic.
  • Does there seem to be a consensus among experts on this topic?
  • What is the best source you can find on this topic?

"T" stands for Trace Claims, Quotes, and Media to the Original Context:

Many things online are not in their original context, which can make it difficult to evaluate credibility.

  • Examine your source to see if it may have information that is out of context.
  • If your source contains images, are they from another source? 
  • Could videos or images in your source have been altered from the original?
  • If your source contains a video, can you trace where it is from?  
  • If your source contains quotations, can you check the original source?

 

Lateral Reading for Source Evaluation

vertical reading vs. lateral reading for evaluating websites.  Vertical reading: read the website's about page, look at the web address to see if it is .com, .org, .gov, look for the authors name and any information about them that might be available on the website, look to see when the website was last updated.  Lateral Reading: search for the website on google to look for reviews of it, find out who is clting or linking to the website, verify the author's credentials in another source, fact check information from the site in outside sources, look for information about the website's reputation in other credible sources.
