Opinion and evidence
An opinion is what someone thinks or feels is right: "Homework should be short." A fact can be checked; an opinion is a view that people may share or not.
To make others believe an opinion, give evidence: a reason (why you think so) and a proof (a fact, number or example). Join them with because.
Check the link
Ask: "Does this evidence really show that my opinion is right?" If the answer is no, the evidence is off-topic, even if it is true.
Concrete and abstract
Concrete words name things you can see, touch, hear or count: neem tree, 28 degrees, a red bus.
Abstract words name ideas, feelings or groups: nature, fairness, comfort, transport.
One idea can sit on several levels. Neem (concrete) is a kind of tree (middle), and trees belong to nature (abstract).
Going up and down the ladder
- Going up (abstract): when you see many examples, say what they have in common. This is a summary or a main idea.
- Going down (concrete): when someone says an idea, ask "Can you give an example?"
A clear text uses both. Only abstract words feel foggy. Only examples feel like a list with no point.
Putting both together
Strong evidence is usually concrete: a number, a name, an example. A strong opinion is usually abstract enough to cover those examples. Write the opinion, then support it with two concrete pieces of evidence and a "because".
Try it
Pick an opinion about your school. Write two concrete examples as evidence. Then write one abstract sentence that sums them up. Swap with a friend and check the link.
Key formulas and definitions
- Opinion + reason + proof (joined by "because") = a supported opinion
- Concrete = can see, touch, count
- Abstract = general idea or feeling
- Up the ladder = general; down the ladder = example
- Evidence must connect to the opinion
Worked examples
1. Sort into concrete or abstract: pencil, honesty, 12 students, freedom.
Concrete: pencil, 12 students. Abstract: honesty, freedom.
2. Opinion: "Cycling is good for students." Which is better evidence: "Cycles are blue" or "Ten cyclists in our class reached school 5 minutes earlier"?
The second. It is concrete and connects to the opinion. "Cycles are blue" is true but does not support it.
3. Climb up the ladder for: sparrow, crow, pigeon.
Bird (middle level), then animal or living thing (more abstract).
Common mistakes
- Giving a true fact that does not connect to the opinion.
- Treating an opinion as a fact because many people agree.
- Using only abstract words with no example.
- Listing examples without ever saying the main idea.
