According to experts, "fake news," is "fabricated information that mimics news media content in form but not in organizational process or intent. Fake-news outlets, in turn, lack the news media's editorial norms and processes for ensuring the accuracy and credibility of information. Fake news overlaps with other information disorders, such as misinformation (false or misleading information) and disinformation (false information that is purposely spread to deceive people)." [David M. J. Lazer, et al. "The Science of Fake News," Science, 9 Mar. 2018: vol. 359, no. 6380, pp. 1094-1096.]
"Fake news" has also become a buzzword for those who want to call attention to this biased or inaccurate information, as well as for those who use the accusation "that's fake news!" as a way to defend their own points of view, discredit other perspectives, or even deflect attention from their own disinformation.
Clickbait fuels the dissemination of fake news and filter bubbles (or "echo chambers") create a lack of variety in the information and ideas to which individuals are exposed.
Oxford Living Dictionaries defines clickbait as "(on the Internet) content, especially that of a sensational or provocative nature, whose main purpose is to attract attention and draw visitors to a particular web page."
A filter bubble or echo chamber is the result of website algorithms designed to determine which content you want to see and which you don't, based on your past behavior and other information about you. Over time, the web content you see represents an increasingly narrow range of information and ideas, and you are exposed to fewer and fewer experiences, ideologies, and perspectives that differ from yours.
