i have found this post and infographic and i want to share it
zetabrarian's blog says they are a socially progressive librarian monsterfucker, which a quick scroll through their blog seems to support. This makes them pretty cool but not necessarily the perfect source -- anyone can say they are a librarian, and surely not every librarian is correct about processing information
if i go to a search engine (in this case google via firefox) i see that several universities, libraries from large municipalities (like Los Angeles) as well as the BBC all agree that this is a real method experts in information fields recommend. I wouldn't necessarily take any single one of these sources as 100% credible, but they are individually reasonably reliable, and taken together indicate a high probability of factual information
TRACE TO ORIGINAL CONTEXT
A brief search reveals that the SIFT method was created by Mike Caulfield, who is a research scientist at the University of Washington’s Center for an Informed Public, where he studies the spread of online rumors and misinformation. This is an extremely good source of information for how to process information on the internet. As the creator of the SIFT method, he has taught thousands of teachers and students how to verify claims and sources through his workshops.
It corroborates the above information, though there are a few notable differences. For example, under the "trace to original context" section in the Washington U. source (again, as close to the original as i could find) this step contains advice to check the date. This seems very good to include, as in the fast moving world of internet information, things become outdated or get updated very quickly, and yet first takes and outdated articles hang around and get shared for a long time.
I personally find that it is important to outright search for the opposite information. For example, I put in a few searches like "Mike Caulfield discredited" "Mike Caulfield wrong" "SIFT method bad" etc. I found nothing showing me any indications this method has any problems. Interestingly, somehow this did turn up an article about news literacy on Medium, which was actually written by Mike Caulfield in April of 2017
