Misinformation and disinformation

Misinformation is false or misleading content shared without intent to deceive; disinformation is spread deliberately, often in coordinated campaigns. Both exploit attention, emotion and gaps in trusted information. Responses range from labelling and prebunking to platform rules and law, and each carries risks to free expression. This page sets out how false information spreads and is countered, the records that measure it, and who decides.

01In brief

The short answer.

Misinformation is false or misleading content shared without intent to deceive; disinformation is spread deliberately, often in coordinated campaigns. Both exploit engagement-driven ranking, coordination and information gaps. Legislatures, platforms, digital services regulators and electoral authorities hold the decisions on responses.

03The question

Misinformation and disinformation: how the risk develops.

Information harms and analytical limits. The dossier below sets out how the risk develops, what is measured, where the data come from, how it is modelled and who decides.

Mechanism

Engagement rewards the sensational

Ranking systems that optimise for engagement favour emotive and novel content, which false claims often are. Reach grows faster than corrections can follow.

Mechanism

Coordination amplifies

Networks of accounts, paid influencers and automated tools make fringe narratives look popular. Coordinated inauthentic behaviour is a pattern of conduct as much as a content problem.

Mechanism

Gaps invite false claims

Where official information is late, unclear or distrusted, people fill the gap with whatever circulates. Data voids on new topics are exploited quickly.

Mechanism

Remedies risk overreach

Laws against false information can be used against journalists and critics. Responses that target behaviour and transparency carry less risk to expression than bans on content.

04Key terms

Terms used on this page.

Each term as this page uses it. Where a standard-setting body defines the term, the wording follows that body.

TermDefinition
MalinformationGenuine information shared out of context or to cause harm, such as leaked private data.
PrebunkingWarning people in advance about manipulation techniques or likely false claims so they recognise them later.
Data voidA topic or search term for which little reliable content exists, which manipulators can fill.
05Indicators

What is measured, and how well.

Each indicator carries its unit, its cadence, the kind of source behind it and the evidence label a value would carry. No values are shown: a programme supplies them under its own authority.

06Canvas

From sources to decisions.

The topic as a computational graph: named sources feed the methods, an evidence review gates the outputs, and the decisions stay with the authorities that hold them.

Pipeline canvas · Misinformation and disinformation as a run graphDesign, not a record
Misinformation and disinformation: responding to harmful informationPublic narratives are monitored; items are detected and their provenance verified; harm is assessed against a threshold; the response (correct, prebunk, label, escalate) is chosen and reported transparently.

09Core questions

What experts ask.

Researchers on misinformation and disinformation ask questions that resist easy answers.

  • How prevalent is false or misleading content, and how much of it do people actually see?
  • Who shares it, why, and through which networks?
  • Does exposure change beliefs and behaviour, and for whom?
  • How are coordinated disinformation campaigns organized, and how can they be detected?
  • Which responses reduce harm without suppressing legitimate speech?
10Mechanisms and drivers

Spread, susceptibility and context.

False content can spread through social networks, especially when it is novel, emotional or confirms existing beliefs. Network research shows that a small number of highly active accounts often account for much of the sharing. Coordinated campaigns, sometimes using automated or inauthentic accounts, can amplify narratives and make fringe views appear widespread.

Exposure does not translate simply into belief or action. Research suggests that effects are concentrated among those already predisposed, that people use many sources, and that distrust in institutions makes alternative narratives more attractive. Measuring harm is difficult, and estimates of prevalence depend heavily on definitions and data access. Overstating the problem can itself erode trust and justify disproportionate responses.

11Methods and data

How the evidence is built, and where it stops.

  1. 01

    Content and network analysis

    Tracing how content spreads using network science. Platform data access is limited and uneven.

  2. 02

    Automated detection

    Classifiers that flag likely false or coordinated content using machine learning. Error rates and biases need disclosure.

  3. 03

    Experimental research

    Testing effects of exposure and interventions with social and behavioural science. Lab settings may not reflect real behaviour.

  4. 04

    Case investigation

    Detailed study of specific campaigns. Attribution to actors is often uncertain.

13Questions

Questions and answers.

What is the difference between misinformation and disinformation?
Misinformation is false or misleading content shared without intent to deceive; disinformation is false content created or spread deliberately to deceive or cause harm.
What is prebunking?
Warning people in advance about manipulation techniques or likely false claims, so they recognise them later. Experimental studies report effects of varying size and duration.
Do laws against false news work?
Evidence on their effect is limited, and human rights bodies have documented their use against journalists and critics. Many experts favour transparency and process duties over content bans.
Is all false information harmful?
No. Much is trivial or quickly corrected. Harm depends on content, reach, audience and context, which is why careful analysis matters.
Can disinformation be reliably attributed to its source?
Sometimes, with strong technical and contextual evidence. Often attribution remains uncertain, and claims should state their confidence.
Do fact-checks work?
Research suggests corrections can reduce belief in specific false claims, but effects vary and may fade. They are one tool among several.
