The SIFT Method
For more information about the SIFT method you can read the free, short ebook: Web Literacy for Student Fact Checkers by Mike Caulfield (Washington State University).
The CRAAP test is a basic set of evaluation criteria and questions that you can apply to any source that you find. CRAAP is an acronym for Currency, Relevance, Authority, Accuracy, and Purpose.
Currency: the timeliness of the information.
Relevance: the importance of the information for your needs.
Authority: the source of the information.
Accuracy: the reliability, truthfulness, and correctness of the content.
Purpose: the reason the information exists.
Lateral reading helps you determine an author's credibility, intent, and biases by searching for articles on the same topic by other writers (to see how they are covering it) and for other articles by the author or organization that you're checking on. This is one of the strongest tools in your fact checking toolkit. Ideally lateral reading is an essential part of both the CRAAP test (notably the "Can you verify any of the information in another source or from personal knowledge?" question under the "Accuracy" criteria) and SIFT method (essentially Step 3's "Is there a consensus for the information provided?"), but it might help to understand this as a strategy of its own.
You can learn more about this strategy using the library's Lateral Reading Tutorial.
