Why we tend to believe what we read online
The internet is usually the first place we look for answers, whether for work, a school project or university study. A quick search will turn up something that reads like a clear, confident explanation.
Because it's in writing, often on a tidy-looking website, it's easy to accept without a second thought. But a writer can be sincere and still be wrong, so it helps to ask how much weight a source can carry.
Open websites and where they fall short
Almost anyone can publish on the web. That openness gives us information on nearly every subject, but no guarantee the writer knows what they're talking about.
It's tempting to rely on the first few search results, where Wikipedia often appears. It can be a useful starting point, and volunteer editors correct errors and remove vandalism, but quality varies between articles. Check the references behind important claims rather than relying on the page alone.
Blogs, forums, social media posts and personal websites need the same caution. Some writers are well informed. Others repeat something half-remembered, or want to sell a product or promote a view.
AI chatbots and AI-generated summaries can produce fluent text containing errors or invented details. They may also cite references that don't exist or don't support their answers. Images, videos and screenshots can be edited, generated by AI, or shown with a false date or location.
A high search ranking isn't a guarantee of accuracy. Search engines use many signals to rank pages, and paid adverts may appear above ordinary results.

How to check what you find
These checks can help you decide what deserves closer attention.
- Who wrote it? Look for a named author or organisation with relevant knowledge or qualifications.
- Is the website what it claims to be? Watch for lookalike addresses and fake official pages. A professional design, logo or padlock symbol doesn't make information true.
- When was it written? Rules, prices and advice change, and an "updated" label doesn't mean every claim has been reviewed.
- Why was it written? A page selling something may present only one side.
- Does it cite sources, and do they back it up? Open the links and check they actually say what the page claims.
- Do other sources agree? Trace claims to where they started. Several sites copying one report don't count as independent confirmation.
- Be wary of emotional language, dramatic headlines and claims that seem too neat or too surprising.
- Treat AI answers as a prompt for further checking, not a final answer.
For health, legal and financial decisions, use current official guidance and, where needed, appropriately qualified advice.
Where to find reliable sources
Official rules, rates and thresholds for tax, benefits and pensions can change each year, so go to the source. GOV.UK covers many of these, but some rules and services differ between England, Scotland, Wales and Northern Ireland. Check that guidance applies where you live: see mygov.scot, GOV.WALES or nidirect.
The NHS website is useful for medical information but is mainly aimed at England. For local services, use NHS inform in Scotland, NHS 111 Wales or nidirect in Northern Ireland. Citizens Advice covers consumer rights, money and housing, with Citizens Advice Scotland and Advice NI serving Scotland and Northern Ireland.
The Office for National Statistics publishes official figures, but check the coverage: a figure may apply to the UK, Great Britain, England and Wales, or one nation. To test a claim from the news or social media, try Full Fact, an independent fact-checking charity, or BBC Verify, the BBC's verification team.
School, college and university libraries can help students find sources suited to their subject and assignment, including peer-reviewed research, though peer review is a check rather than a guarantee. Teachers and lecturers can advise on what's acceptable for coursework.
The UK Safer Internet Centre and Childnet offer free resources for parents talking with children about this.
Before relying on something you've read online, ask who said it, how they know, and whether anyone independent has confirmed it.
