My humble advice:
1. If you read through a forty-line story and there's only marginally two lines of pure fact...the odds are that there's a fair amount of 'sway' or disinformation in the piece.
2. If 'anonymous' sources are the primary structure of the article/news....it's best to just discard it.
3. If they tell you right away that their data has been fact-checked....like in paragraph two, then it's probably wise to ask who the fact-checker is, and their background or past.
4. Typically, the headline of a disinformation piece is signaling you ahead of time.....so look over the headline carefully.
5. Finally, if the article is written to help someone or some group, or to harm someone/some group.....the odds are heavily in favor of it being disinformation.
