Information Online

Part of being a good researcher - part of being a good citizen - is learning how to critically evaluate the information you find online. Academic journal articles go through a process of peer review and editing, but the Internet has billions of websites of varying quality and origin. On social media platforms, there are billions upon billions of posts with information and claims of fact. 

Here are a few tips on evaluating online sources of information.

Evaluating Websites

When you come across a website that has interesting information, you can use the "CARS" method to critically evaluate the website's content. CARS stands for:

  • Credibility
  • Accuracy
  • Reasonableness
  • Support
Credibility
  • Trustworthy source
  • Author’s credentials
  • Evidence of quality control
  • Known or respected authority
  • Organizational support
Goal: an authoritative source, a source that supplies some good evidence that allows you to trust it.
Accuracy
  • Up-to-date
  • Factual
  • Detailed
  • Exact
  • Comprehensive
  • Audience and purpose reflect intentions of completeness and accuracy
Goal: a source that is correct today (not yesterday), a source that gives the whole truth.
Reasonableness
  • Fair
  • Balanced
  • Objective
  • Reasoned
  • No conflict of interest
  • Absence of fallacies or slanted tone
  • Common sense
Goal: a source that engages the subject thoughtfully and reasonably, concerned with the truth.
Support
  • Listed sources
  • Contact information
  • Available corroboration
  • Claims supported
  • Documentation supplied
Goal: a source that provides convincing evidence for the claims made, a source you can triangulate (find at least two other sources that support it).

Evaluating Social Media Posts

Even if you are not researching a topic for an assignment, you are bombarded all the time with information - whether on TV, Facebook, Twitter, or TikTok. The SIFT method helps you sift through all of the information that comes your way even when you're not researching!

  • Stop
  • Investigate
  • Find better coverage
  • Trace claims, quotes, and media back to their original context

Here is a video from Wayne State University that explains the SIFT method:


Stop

  • Content?
  • Date?
  • Author?
  • Publisher?

Investigate the source

  • Who is the author?
  • Are they credible?
  • What is their expertise?
  • What is their agenda?

Find better coverage

  • Find other sources that cover the information and compare.

Trace claims, quotes, and media back to their original context

  • Look up where the information came from. News source? Joke?
