Chapter 4: Fact Checking & Misinformation

4.2 Evaluating with SIFT

SIFT is an acronym developed by Mike Caulfield (2019) that describes four steps you can use to evaluate sources. The four steps included in SIFT are:

  • S: Stop
  • I: Investigate the source
  • F: Find better coverage
  • T: Trace information back to the source

Throughout the next few pages, we’ll be exploring each of these steps and how you can integrate them into your everyday habits for evaluating content. Below is a graphic from Suzanne Sannwald that provides another overview of the SIFT Method.

Below are simple habits to practice when looking at information...    Stop          Do you know the website?          What is its reputation?          What is your purpose?          How do you feel?          Consider cognitive biases.      Investigate the Source          What exactly is the source?          What can you find out about the website?           What about the author?          Is it worth your time?          Stuck? bit.ly/waacinfo Try steps under [W]ebsite & [A]uthor      Find other coverage          Is other coverage similar?          Can you find a better source?          One more trusted?          More in-depth?          What do expert sources agree on with coverage?

Why SIFT?

You might have been previously introduced to CRAAP, a checklist created in the 2000s for evaluating sources. CRAAP tells you to analyze a webpage by taking what it contains and how it is presented at face value and in isolation. Because there is now an overwhelming volume of information and misinformation available online, to really evaluate the trustworthiness of a source, you need to learn more about where the content within a source comes from so you can make a more informed decision about its value. SIFT helps you do that by walking you through practices you can use to get a broader view of a source and fully evaluate its content.

In contrast to other evaluation methods, SIFT presents evaluation as a set of steps you can use and modify, rather than treating the evaluation process as a checklist of attributes that are universally good or bad. When doing research as an NKU student, it is important to use this method to properly evaluate and analyze information you find. After all, you will want to evaluate the information in a newspaper article differently from the research you find in a peer-reviewed journal article. Sometimes you will need to navigate through all four of the steps in SIFT to determine a source’s usefulness and reliability, while other times you will only need one or two. What makes SIFT powerful is that it helps you engage with evaluation as an ongoing process. As the creator of SIFT explains, these steps don’t necessarily need to follow the same order every time. Although Stop will always come first, the other three steps can be executed in any order that makes sense for your situation![1]
