Disinformation and Misinformation 101: Definitions

This blog post, written by members of the Library's Information Integrity Team, is a new series that covers disinformation and other related subjects. The goal is to help create a well-informed citizenry of active participants who shape our world.


DISINFORMATION is false information created and spread purposefully to deceive people for financial gain, for political power, to create chaos or confusion, or for satire. It can take the form of an outright lie, a photo taken out of context leading the viewer to a false conclusion, a doctored image, or a video showing someone saying something they never actually said (called a “deep fake”).

MISINFORMATION is false information spread unknowingly by me or you. For example, when I hit “share” on a post that is disinformation, I am creating misinformation—even if I think it is true or I don’t mean any harm.

Common Types of Disinformation/Misinformation

IMPOSTER CONTENT

Using logos or other branding to fool people into thinking the information is from a trusted news site or organization.

MISLEADING CONTENT

Presenting information in a misleading way, such as presenting a comment as fact.

FALSE CONTEXT

When content is shown in a false context, such as when an old photograph is used to imply that it accurately represents a current event.

FABRICATED CONTENT

Information that the creator makes up and knows to be false. 

MANIPULATED CONTENT

When content is changed intentionally to create a false conclusion different than its original message. Altered photographs or videos are examples.

SATIRE

Presenting false but funny stories as truth, such as in The Onion. The creator may not have intentionally meant to fool people, but these stories are sometimes spread by people who think they're true.
