GCSE-readyCritical reading: bias, evidence and claims
The specification asks you to recognise bias and the misuse of evidence, and to tell the difference between statements that are supported by evidence and statements that are not. This makes your evaluation (AO4) much sharper.
Fact, opinion and claim
| Type | What it is | Example |
|---|---|---|
| Fact | Can be checked and shown to be true | The school opened in 1962. |
| Opinion | A personal view or judgement | It is the best school in the county. |
| Supported claim | A view backed by evidence the reader can weigh | Attendance rose from 91% to 95% after breakfast club began. |
| Unsupported claim | A view presented as true with no evidence | Everyone knows breakfast clubs work. |
Practice extract
Every sensible person now agrees that mobile phones are ruining our schools. Last week I asked twelve parents at the school gate, and eleven of them told me phones should be banned. That says it all. Since Hillside Academy down the road banned phones, its exam results have gone up, which proves that the ban works. Of course, a few so-called experts will say that phones can help with learning, but they have clearly never set foot in a real classroom. Teenagers today are glued to their screens from morning till night. It is time for every school to act.
Signs of bias and misused evidence
Loaded words: 'so-called experts', 'glued to their screens'.
Sweeping generalisations: 'every sensible person', 'teenagers today'.
Tiny or unfair samples: twelve parents at one gate.
Cause and effect assumed: results went up after a ban, so the ban must be the reason (other causes are ignored).
Attacking people, not ideas: dismissing opponents instead of answering them.
Bias is not always bad: a column is meant to persuade. Your job is to notice it and judge how convincing the writing is.
Why is 'eleven out of twelve parents agreed' weak evidence?
- The sample is tiny: only twelve people.
- They were all at one school gate, so they may not represent other parents.
- We do not know what exactly they were asked.
Answer: The sample is very small and unrepresentative, so it cannot show what parents in general think.
Separate facts from opinions, check whether claims are supported, and look for loaded words, generalisations, tiny samples and assumed causes. Then judge how far the bias weakens or strengthens the writing for its purpose.
- Bias
- Presenting one side unfairly, leaving out or playing down evidence for the other side.
- Purpose
- What a text sets out to do, such as to argue, persuade, inform, advise, describe or entertain.

Answer: 'Teenagers today are glued to their screens from morning till night.'
It claims all teenagers behave the same way.
'Eleven of them told me phones should be banned. That says it all.' What is the flaw?
- It treats a tiny sample as if it settles the argument
- It uses no numbers
