Disinformation is any communication (either overt or covert) containing intentionally false material, often combined selectively with true information, which seeks to mislead and manipulate an audience. The volume and velocity of the current disinformation tsunami surrounding COVID-19 is unprecedented compared to any other time in human history.
Fake news is a multi-step process that involves making or taking content that others have produced, passing it off as real news, and capitalizing on social media to get as much attention as possible.
We define “fake news” to be 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).
“Fake news” is a term that can mean different things, depending on the context. News satire is often called fake news as are parodies such as the “Saturday Night Live” mock newscast Weekend Update. Much of the fake news that flooded the internet during the 2016 election season consisted of written pieces and recorded segments promoting false information or perpetuating conspiracy theories. Some news organizations published reports spotlighting examples of hoaxes, fake news and misinformation on Election Day 2016.
Misinformation is false or misleading information that is unwittingly shared, while disinformation is deliberately created and distributed with an intent to deceive or harm.
Arguably the most commonly applied definition of misinformation is the one offered by Lewandowsky et al. (6), who refer to misinformation as “any piece of information that is initially processed as valid but is subsequently retracted or corrected” (6). Others have removed the “processing” element from this definition, describing misinformation as information that is initially presented as true but later shown to be false (e.g., refs. 7 and 8).
