There are multiple mnemonic devices for what you should consider when evaluating an information source, but they all target the same basic principles of evaluating who is saying the info and why, and whether they have solid evidence to back up their claims (plus whether the info is of the right time frame to still be relevant!).
Caveat!
These tests/checklists generally rely on what's called vertical reading: evaluating an information source based on how it presents itself. However, recent research indicates that this is often insufficient. Professional fact-checkers can more quickly and accurately gauge the accuracy of a source by engaging in lateral reading. As you read an article, pop open additional tabs to look up and verify claims against other sources, rather than staying siloed in looking solely at the one article.
For best results, employ both strategies.
