S. I. F. T. is an evaluation strategy to help you judge whether or online content can be trusted for credible and reliable information. The SIFT strategy is quick, simple, and can be applied to various kinds of online content: social media posts, memes, statistics, videos, images, news articles, scholarly articles, etc.
Credible sources are those a reader can trust.
Example: The Wall Street Journal newspaper is credible, but not scholarly.
