STOP reminds you of two things.
1. When you first arrive at a page and start to read it — STOP. Ask yourself: Do I know and trust the website or source of the information? If you don't, follow the other moves to get a sense of what you're looking at. Don't read it or share it until you know what it is.
2. Once you begin the SIFT process and go through the moves, it can be too easy to go down a rabbit hole, chasing after more and more obscure facts or getting lost in a "click cycle". If you feel yourself getting overwhelmed in your fact-checking efforts, STOP and take a second to remind yourself what your goal is. Adjust your strategy if it isn't working. Make sure you approach the problem at the right amount of depth for your purpose.
This SIFT method guide was adapted from Michael Caulfield's "Check, Please!" course. The canonical version of this course exists at http://lessons.checkplease.cc. The text and media of this site, where possible, are released into the CC-BY, and free for reuse and revision. We ask people copying this course to leave this note intact so that students and teachers can find their way back to the original (periodically updated) version if necessary. We also ask librarians and reporters to consider linking to the canonical version.
As the authors of the original version have not reviewed any other copy's modifications, the text of any site not arrived at through the above link should not be sourced to the original authors.
