Be curios. Be reflective. Actively investigate your news sources.
If you have an immediate emotional reaction to a news article or source: pause, reflect, investigate. Exciting an emotional reaction is a primary goal of fake news producers. Do not be part of a viral fake news spiral.
Independently verify the source (by performing a separate search) and independently verify the information (through more mainstream news sources or fact-checking sites).
Select news sources known for high-quality, investigative reporting. Search these sources directly. Don't settle for web search results or social media news feeds. Social media algorithms are designed to present the news that reinforces your current views, not a balanced view.
Background: "Evaluating news sources is one of the more contentious issues out there. People have their favorite news sources and don’t like to be told that their news source is untrustworthy.
For fact-checking, it’s helpful to draw a distinction between two activities:
Most newspaper articles are not lists of facts, which means that outfits like The Wall Street Journal and The New York Times do both news gathering and news analysis in stories. What has been lost in the dismissal of the New York Times as liberal and the Wall Street Journal as conservative is that these are primarily biases of the news analysis portion of what they do. To the extent the bias exists, it’s in what they choose to cover, to whom they choose to talk, and what they imply in the way they arrange those facts they collect. The news gathering piece is affected by this, but in many ways largely separate, and the reputation for fact checking is largely separate as well."
