Don't Just Share It: How to Fact-Check Claims You See Online

Something crosses your feed. It is alarming, or infuriating, or confirms exactly what you already suspected. A screenshot of a statistic, a clip stripped of context, a bold claim attached to no source. Your first instinct might be to share it, or to fire back at whoever posted it. Before you do either, there is a better path.

This guide is about building a habit. Not the paralysing, cynical habit of trusting nothing, but the grounded, active habit of checking claims before they go further. Misinformation spreads because it triggers an emotional response faster than critical thought can catch up. The remedy is not to stop having emotions about what you see online. It is to give those emotions a moment to settle before your fingers do the talking.

The Pause That Changes Everything

The most powerful thing you can do when you see a provocative claim is wait. Not for hours. Sometimes not even for long. Thirty seconds of deliberate thinking can be enough to break the cycle.

When a claim provokes anger, fear, or outrage, your brain is doing exactly what it evolved to do: responding to a perceived threat quickly. That is useful in many situations. On social media, it tends to make things worse. Misleading content is often designed to exploit precisely this mechanism, presenting information in a way that feels viscerally true and urgent, discouraging the kind of slower, reflective engagement that would reveal its flaws.

Before you react, ask yourself three questions. Is this claim specific enough to verify? Does it include a source, and if so, is that source named and findable? Does it seem designed to make you feel a particular emotion rather than inform you? These questions do not tell you whether the claim is true or false. They tell you whether it is worth looking more carefully before sharing.

Non-Violent Communication, or NVC, offers a useful frame here. The GreenMeans De-escalation Toolkit at toolkit.greenmeans.ovh is built around the idea that separating observation from reaction is the starting point for productive communication. Before you can respond clearly to a claim, you need to know what you actually observed, as opposed to what you interpreted or felt. A screenshot asserting that a policy costs a certain amount is an observation. The conclusion that someone is lying or that the country is falling apart is an interpretation. Keeping them separate is not pedantry. It is the foundation of accurate thinking.

The Anatomy of a Claim Worth Checking

Not every viral post requires an investigation. Some things are obviously implausible nonsense. Others are so vague that no single source could confirm or refute them. The claims most worth investigating tend to share a particular shape.

They are verifiable in principle. They assert something concrete: a number, a policy, a legal rule, an event. They carry some surface plausibility, meaning they are not obviously absurd on their face. And they have consequences, meaning that if true, they would matter.

Watch out for claims that cite no source at all, or cite a source that does not appear to actually exist. Watch out for precise-looking numbers with no reference to where those numbers come from. Watch out for claims that present a single case or anecdote as representative of a broader pattern. Watch out for claims that combine a true fact with a false conclusion, accurately stating that X happened while falsely implying that Y caused it. And watch out for official statistics that have been stripped of context to make them appear to say something they do not.

None of these features proves a claim is false. They are flags that tell you it deserves closer examination.

Where to Go When You Want Answers

Several well-resourced organisations exist precisely to do this work, and their outputs are publicly available and free to access.

Full Fact (fullfact.org) is the UK's leading independent fact-checking organisation. It has been operating since 2010, covers UK politics and public life specifically, and publishes detailed breakdowns of particular claims: where the numbers come from, what they actually show, and where the original claim went wrong. If a UK political claim has been circulating widely, there is a reasonable chance Full Fact has already looked at it.

BBC Reality Check, accessible through the BBC News website, applies similar rigour to claims that emerge in national news and political debate. It is particularly useful during elections or major policy announcements, when misleading statistics tend to multiply quickly.

Channel 4 FactCheck (channel4.com/news/factcheck) has been publishing detailed investigations into political claims and statistical assertions since 2005, and its archive covers a wide range of domestic and international topics.

Reuters Fact Check (reuters.com/fact-check) is valuable for claims that originate outside the UK or that involve international events, institutions, or statistics.

For raw data, the Office for National Statistics (ons.gov.uk) is the authoritative source for most domestic figures covering crime, employment, migration, health, housing, and a great deal more. The UK Government's own website at gov.uk is equally important for checking what legislation or policy guidance actually says, as opposed to how it has been characterised in a viral post.

These are not the only reliable sources, but they are among the most dependable starting points. A search combining the name of one of these organisations with the specific claim you are checking will often surface an existing analysis within seconds.

Three Claims, Fact-Checked

The most direct way to demonstrate the process is to walk through it. What follows are three claims that circulate regularly in online spaces, frequently shared in good faith by people who genuinely believe them. Working through each one shows what careful investigation looks like in practice.

"Asylum seekers receive more in state support than British pensioners."

This claim, and variations of it, appears repeatedly on social media and has been circulated widely enough that Full Fact has examined it on multiple occasions. A proper investigation requires comparing what asylum seekers actually receive with what pensioners are entitled to. Asylum seekers in the UK are housed and receive a modest weekly allowance intended to cover food, clothing, and toiletries. That allowance is not comparable in scale to the full State Pension, and when like is compared with like, the claim does not hold up. The versions of this claim that circulate online typically conflate different categories of support, compare figures that are not directly comparable, or rely on numbers that have no verifiable origin. The evidence does not support the conclusion.

"The UK's contribution to global CO2 emissions is so small it doesn't matter what we do."

This one deserves a different kind of scrutiny, because it contains a real statistical fact used to reach an unjustified conclusion. The UK does account for a relatively modest share of current annual global emissions. That part is accurate. What the claim consistently omits is that the UK was among the world's first industrialised nations and carries a significant share of historical cumulative emissions that have already accumulated in the atmosphere. Per-capita UK emissions also remain relatively high by global standards. International climate agreements are built on the principle that wealthier, historically industrialising countries bear a proportionate responsibility for action. The statistic used in this claim is real. The conclusion drawn from it misleads by design.

"Crime has gone up because of immigration."

This is a causal claim rather than a statistical one, and causal claims require a stricter standard of evidence than correlational ones. Establishing causation requires not only identifying a relationship between two variables, but showing a plausible mechanism, ruling out alternative explanations, and controlling for confounding factors. When researchers examine the actual relationship between immigration and crime rates in the UK, using data from the Office for National Statistics and similar authoritative sources, they do not find evidence of a positive causal link. The claim tends to conflate different types of offending, different categories of migrant status, and different time periods in ways that the underlying data does not support. Again, the facts are available. They simply do not point where the claim suggests.

In each case, the method is the same. Identify the specific claim. Find the original source if one exists. Check it against data from authoritative institutions. Distinguish between what the evidence actually shows and what the claim asserts.

Once You've Found the Truth: Responding Well

Finding out that a claim is false is only half the work. Deciding what to do with that information matters just as much, and this is where communication skills become genuinely important.

The natural instinct is to correct firmly and immediately. You have done the research, you have the evidence, and the person sharing false information ought to know. In practice, public corrections delivered with contempt tend to produce defensiveness rather than reflection. The person who shared the claim may double down. Others watching the exchange may take away nothing useful. The correction may even trigger what researchers sometimes call the backfire effect, where challenged beliefs are held more tightly rather than revised.

The GreenMeans De-escalation Toolkit at toolkit.greenmeans.ovh sets out a four-part framework grounded in Non-Violent Communication: observation, feeling, need, and request. Applying it does not mean being soft on misinformation. It means communicating in a way that has a genuine chance of landing.

An observation-based response might take this shape: you noticed a specific claim being shared, you felt concerned because accurate information matters for informed decision-making, and what you would like is for people to look at the original data before drawing conclusions. That is not weakness. It is a method of engagement that keeps the conversation open rather than slamming it shut.

The toolkit's section on empathy guesses is equally practical here. Someone sharing a misleading claim about immigration may be genuinely worried about housing, public services, or economic security. Those concerns are real, even if the claim they encountered gave them an inaccurate target. Acknowledging the underlying concern while challenging the specific claim is far more likely to reach someone than treating them as an adversary. As the toolkit puts it, the goal is to connect before you correct.

This is not merely good manners. It is strategy. A correction delivered with empathy and evidence has a far better chance of being heard than one delivered with contempt.

Why Staying Engaged Matters

When faced with the sheer volume of misleading content circulating online, it can feel tempting to stop engaging altogether. One corrected post seems vanishingly small against the scale of what spreads every day. The research on how misinformation travels, however, suggests that individual action genuinely matters. Accurate information that reaches people early, before a false claim has been widely shared, can reduce how far that claim spreads. Communities with higher levels of media literacy are more resilient to coordinated disinformation campaigns. The choice to disengage, to stop correcting, to stop engaging with the information environment, does not reduce the volume of false claims. It simply leaves them unchallenged.

Misinformation thrives on two things: emotional amplification and social silence. The people who share misleading content most effectively are counting on the rest of us to feel too tired, too outnumbered, or too cynical to respond. The pause before the reaction, the search for a primary source, the calm response that acknowledges the person while correcting the specific claim: none of these are grand gestures. Individually they are small. Collectively, they shape the information environment that everyone lives and makes decisions within.

Hate and falsehood do not win because they are more powerful. They win when accurate, grounded voices stop showing up. The remedy is straightforward, even if it requires patience: look before you share, check before you respond, and when you do respond, do it in a way that keeps the door open. The tools to do this exist, they are free, and the habit can be built by anyone willing to pause for thirty seconds before hitting send.
