An example becomes useful evidence only when the writer explains what it demonstrates and why it matters to the claim. A famous event, personal anecdote or current issue placed beside an argument does not prove anything by proximity. Evidence needs a reasoning bridge.
Example and evidence are not identical
An example is a case. Evidence is material used to support a proposition. The same example can support one claim, fail to support another, or even undermine a claim depending on how representative and relevant it is.
The evidence conversion sequence
- Select: choose a case relevant to the exact claim.
- Specify: state the features of the case that matter.
- Interpret: explain what those features demonstrate.
- Limit: avoid claiming more than one case can support.
- Return: connect the interpretation explicitly to the thesis.
Worked example
Claim: Public spaces are more useful when planners consider different users.
Weak use of example: “For example, some parks have ramps and shaded seating.”
Stronger use: “Ramps allow wheelchair users and people pushing prams to move through spaces that stairs would restrict, while shaded seating makes longer visits more practical for older users and families. These features show how design choices can widen who is able to use a public space comfortably.”
Representativeness matters
One unusual case cannot safely prove a universal claim. If one student succeeds without revision, that does not establish that revision is unnecessary. Ask whether the example is typical, exceptional or merely illustrative.
Personal examples need analytical discipline
Personal experience can illuminate an argument, but it carries limited generalising power. “My class became quieter after phones were collected” may illustrate a mechanism worth discussing, but it does not establish that every school will experience the same result.
Historical and current examples
Use only the part of the case you can explain accurately. A complicated event reduced to a slogan can weaken credibility. If exact facts are uncertain during an examination, choose a simpler example you understand well rather than decorating the essay with fragile detail.
The “so what?” sentence
After every example, ask “So what does this show?” The answer is often the missing analytical sentence. If you cannot answer, the example may be irrelevant or your claim may be unclear.
Evidence strength ladder
Different claims require different support. A personal observation may be enough to illustrate an experience. A broad factual claim may require stronger, more representative evidence. A causal claim needs evidence capable of distinguishing cause from coincidence. Match evidence strength to claim strength.
Practice
Example: A neighbourhood library extends weekend hours and attendance rises.
Weak conclusion: “This proves all libraries should stay open longer.”
Defensible use: “The rise in attendance suggests that opening hours can affect accessibility in some communities, although other factors would need to be examined before generalising the result to every library.”
