Source criticism according to the SIFT-method follows four steps:
S - Stop. Does the source seem reliable, what do you know about the source from before?
I - Investigate the source. Search for more information on the source from other sources. Who has written the source and could there be a hidden agenda?
F - Find better coverage. Has the information been mentioned in other sources, especially sources you know deliver reliable facts or news?
T - Trace claims, quotes and media to the original context. Find primary sources confirming the information.
