What Is Misinformation and How Do You Spot It?

Misinformation is false or inaccurate content shared without the intent to deceive: the person sharing it genuinely believes it. This sets it apart from disinformation, where the spread of false content is deliberate and coordinated. Spotting misinformation on social media involves five quick checks: (1) Can you find the same story from a credible outlet? (2) Is the headline supported by the article body? (3) Is the author identifiable and credentialed? (4) Does the content provoke a strong emotional reaction, especially urgency or outrage? That is a common feature of viral misinformation. (5) Has a fact-checker already assessed the claim? Tools like Google Fact Check Tools Explorer and Full Fact search hundreds of previous verdicts instantly. If any check fails, pause before sharing. Spreading misinformation, even accidentally, amplifies the harm.
Defining the terms: misinformation, disinformation, and malinformation
These three terms are frequently confused in everyday usage. The canonical taxonomy was set out by Claire Wardle and Hossein Derakhshan in their 2017 report “Information Disorder” for the Council of Europe. Understanding the distinctions matters because the correct response to each differs: education for misinformation; platform enforcement or legal action for disinformation.
| Type | Definition | Intent | Example |
|---|---|---|---|
| Misinformation | False or inaccurate content | No intent to deceive | Sharing a debunked health remedy because you believe it works |
| Disinformation | Deliberately fabricated or manipulated content | Intent to harm or further an agenda | A coordinated campaign of fabricated news stories |
| Malinformation | True information used out of context | Intent to harm | A genuine photo from a different event presented as evidence for a current one |
How misinformation spreads: the mechanics
A 2018 study in Science by Vosoughi, Roy, and Aral at MIT analysed millions of stories shared on Twitter and found that false news spread faster, deeper, and more broadly than true news. Humans, not bots, were responsible for the greater part of this. The leading explanation is emotional amplification: content that triggers anger, fear, or disgust generates more engagement and therefore travels further in engagement-optimised feeds, regardless of accuracy.
Two further mechanisms accelerate the spread. Social proof (seeing a high share count or endorsement from trusted contacts) makes content feel credible even when it is false. Algorithmic amplification then compounds both effects by surfacing high-engagement content to larger audiences. Ofcom's Online Safety Act duties require large platforms to assess and mitigate the risks of harmful misinformation as part of their systems and processes obligations.
Seven types of false content
Claire Wardle's seven-category taxonomy, developed through First Draft, gives a more granular picture of the problem than the single word “fake news”:
- Satire or parody: no intent to harm, but can mislead when shared without context
- Misleading framing: accurate content, but a false headline or caption changes its meaning
- Imposter content: fake accounts or sources impersonating real ones
- Fabricated content: 100% invented, designed to look real
- False connection: headline, image, or caption does not match the body of the article
- Manipulated content: genuine content that has been distorted (deepfakes, out-of-context edits)
- False context: genuine content accompanied by false information
How to spot misinformation: a practical checklist
| Question | What to check | Free tool |
|---|---|---|
| Is the source credible? | Lateral reading: search the outlet name before reading | Wikipedia, MediaBiasFactCheck |
| Does the headline match the story? | Read the full article, not just the headline | No tool needed; just read past the headline |
| Is the author real and credentialed? | Search the author's name; check their other published work | Google, LinkedIn |
| Is the framing designed to bypass scepticism? | Note urgency, outrage, or disgust; slow down deliberately | Pause; apply SIFT |
| Has it been fact-checked already? | Search previous verdicts from accredited fact-checkers | Google Fact Check Tools, Full Fact |
Common patterns of misinformation on social media
- Health claims without study links or official guidance: always ask which organisation or study this comes from
- Statistics without source or with cherry-picked date ranges: check the ONS or original dataset
- “Leaked” documents or screenshots of unverifiable claims: screenshots can be fabricated; find the original
- Breaking news where facts are still developing: early reports are frequently wrong; wait for multiple credible sources to confirm
- Old events relabelled as current: reverse-search images to check the original date and context
Cognitive biases that make us vulnerable
Understanding why misinformation is so effective requires recognising the cognitive shortcuts it exploits. Research by Pennycook and Rand (2021), “The Psychology of Fake News” in Trends in Cognitive Sciences, identifies three key mechanisms:
- Confirmation bias: we are more likely to believe information that reinforces our existing views without scrutinising it
- Illusory truth effect: repeated exposure to a claim increases its perceived accuracy, even when the claim is false
- Authority bias: content shared by someone we trust or admire feels more credible, even when that person has not verified it themselves
Awareness of these biases does not eliminate them. Slowing down and applying a structured checklist before sharing meaningfully reduces the error rate.
What to do when you've spotted misinformation
- Do not share: sharing with a “this is false” caption still amplifies the original claim through repetition
- Report to the platform: use the built-in reporting tool so the platform's systems can act
- Submit to a fact-checker: if the claim is widespread and harmful, tip off Full Fact or AFP Fact Check
- Correct gently and privately: if a friend or family member has shared it, a direct message outperforms a public callout for changing attitudes, according to Lewandowsky et al.'s “Debunking Handbook”
UK-specific resources and regulation
In the UK, several organisations and legislative frameworks address misinformation directly:
- Ofcom: the communications regulator; its Online Safety Act powers require large platforms to assess misinformation risks in their systems
- UK Online Safety Act 2023: see the full text on legislation.gov.uk for duties relating to harmful content
- Full Fact: the UK's leading independent, charitable fact-checker; publishes verdicts on claims circulating in UK media and politics (fullfact.org)
Frequently asked questions
What is the difference between misinformation and disinformation?
Misinformation is false or inaccurate content shared without intent to deceive; the person spreading it believes it is true. Disinformation is deliberately fabricated or manipulated content spread to cause harm or further a political or commercial agenda. The distinction matters because the right response differs: education and correction for misinformation; platform enforcement and, in some cases, legal action for disinformation.
Why does misinformation spread so fast on social media?
A 2018 study in Science by Vosoughi, Roy, and Aral at MIT found that false news spreads faster, deeper, and more broadly than true news, and that humans, not bots, are primarily responsible. The leading explanation is that misinformation tends to provoke stronger emotional reactions (anger, fear, surprise), which drives more sharing in engagement-optimised feeds.
How can I quickly check if a claim has already been fact-checked?
Search the claim on Google Fact Check Tools Explorer (toolbox.google.com/factcheck/explorer), which aggregates verdicts from accredited fact-checkers worldwide. For UK-specific claims, Full Fact (fullfact.org) publishes a searchable archive of its investigations. If neither returns a result, the claim may not yet have been reviewed. Treat that as a reason to be cautious, not to assume it is accurate.
Should I share misinformation with a warning label to alert others?
Generally, no. Research on corrections and the “continued influence effect” shows that repeating a false claim, even to refute it, can strengthen its presence in people's memory. Lewandowsky et al.'s Debunking Handbook recommends leading with the accurate information rather than restating the myth. If you want to alert others, share a fact-checker's verdict directly rather than the original false content.
