What Makes a News Story False?
You can't verify its claims
A fake news article may or may not have links in it tracing its sources; if it does, these links may not lead to articles outside of the site's domain or may not contain information pertinent to the article topic.
Fake News appeals to emotion
Fake news plays on your feelings. It makes you angry or happy or scared. This is to ensure you won't do anything as pesky as fact-checking.
Authors usually aren't experts
Most authors aren't even journalists, but paid trolls.
It can't be found anywhere else
If you look up the main idea of a fake news article, you might not find any other news outlet (real or not) reporting on the issue.
Fake news comes from fake sites
Did your article come from abcnews.com.co? Or Realnewsrightnow.com? These and a host of other URLs are fake news sites.
