Sengkang Secondary English tuition should help students understand a basic rule of fair argument: the person making a claim carries the responsibility to support it. A reader is not required to disprove every unsupported assertion before withholding agreement.
This rebuilt legacy URL now owns one distinct Secondary English reasoning job: claim → burden → evidence → challenge → reply → calibrated conclusion. Old broad promotional copy, stale local-centre wording and obsolete contact details have been removed.
eduKateSG does not claim a current Sengkang branch. Current centres are at 83 Punggol Central, Singapore 828761 and 8 Fourth Avenue, Singapore 268674. Selected Secondary English classes run in focused 3-pax small groups, typically 1.5 hours.
The Direct Answer
If you claim:
“This policy is effective,”
you should provide evidence showing what “effective” means and how the policy performs against that criterion.
The reply:
“Prove that it isn’t,”
does not automatically satisfy the original burden.
A challenge does not become evidence simply because the other person cannot immediately refute it.
What Is the Burden of Proof?
The burden of proof is the responsibility to provide adequate support for a claim that another reader or listener is being asked to accept.
It is especially important when the claim is:
- strong;
- surprising;
- causal;
- universal;
- evaluative;
- recommendatory.
Worked Example: “This Method Works”
Claim:
“This revision method works.”
Questions:
- works for what outcome?
- for whom?
- compared with what?
- how was improvement measured?
- over what period?
The claimant should supply support proportional to the strength of the claim.
Strong Claim, Strong Burden
Compare:
“This method helped one student.”
vs
“This method helps every student.”
The second has a much heavier burden because one counterexample can defeat the universal claim.
Negative Claims
Negative claims can also carry a burden:
“This programme has no benefit.”
If the speaker expects others to accept that broad conclusion, evidence is still needed.
The simple rule “you can never prove a negative” is false. Many negative claims can be tested.
Absence of Evidence
“No one has shown that the programme helps, therefore it does not help.”
This can be weak reasoning if the evidence simply has not been collected.
Absence of evidence can matter when strong evidence should be present if the claim were true, but the reasoning must be made explicit.
Worked Example: Missing Records
If a system is supposed to record every completed transaction and the record is absent, that absence may be meaningful evidence.
If no such record system exists, absence tells us less.
Context determines whether missing evidence is informative.
Burden Shifting
Claim:
“This app is completely reliable.”
Challenge:
“What testing supports that?”
Weak reply:
“Can you prove it is unreliable?”
The original claim remains unsupported.
The “Prove Me Wrong” Trap
“I am right until someone proves me wrong” is not a sound general rule for argument.
Reasonable belief should increase with positive evidence, not merely survive because no opponent has produced a refutation.
Default Positions
In some real systems, rules determine defaults:
- legal presumptions;
- administrative procedures;
- scientific null models;
- school rules.
But students should not import those specialised defaults into every everyday argument.
Evidence Proportionality
Ordinary claim:
“The library closes at six.”
A current official timetable may be enough.
Large claim:
“All students learn better at night.”
One anecdote is not enough.
More extraordinary or general claims require stronger support.
Worked Example: Causal Claim
Claim:
“The new timetable caused the improvement in results.”
Burden includes showing:
- results changed;
- timetable changed first;
- groups/conditions are comparable;
- alternative causes are addressed;
- a plausible mechanism exists.
Claim vs Question
Question:
“Could the timetable have contributed?”
This asks for possibility.
Claim:
“The timetable caused the improvement.”
This asserts causation and therefore carries a larger burden.
Burden and Definitions
Claim:
“The policy is fair.”
Before evidence, define fairness.
Without a criterion, the burden cannot be evaluated clearly.
Burden and Quantifiers
“Some students benefited.”
Burden:
show at least relevant cases.
“Most students benefited.”
Burden:
show a representative majority.
“All students benefited.”
Burden:
show every relevant case or a justified universal rule.
Burden and Recommendations
Claim:
“Schools should adopt the programme.”
Support should address:
- benefits;
- costs;
- feasibility;
- alternatives;
- who is affected.
Recommendation creates a decision burden, not merely a factual burden.
Worked Example: Public Transport
Claim:
“Adding buses is the best solution.”
Evidence should show:
- where capacity is insufficient;
- what adding buses changes;
- cost/trade-offs;
- why alternatives are weaker.
“It seems obvious” does not satisfy the burden.
The Claim–Burden Table
| Claim type | Evidence burden |
|---|---|
| specific fact | reliable source/record |
| generalisation | representative evidence |
| causal claim | comparison + alternatives + mechanism |
| evaluation | criterion + evidence |
| recommendation | benefit/cost/feasibility comparison |
Unsupported Counterclaim
Speaker A:
“The policy saves money.”
Speaker B:
“No, it wastes money.”
Now both sides have made claims. Both require support.
Rejecting one unsupported claim does not make the opposite claim true automatically.
Withholding Judgement
A valid response can be:
“There is not enough evidence yet to decide.”
Students sometimes think every discussion must end with yes/no certainty.
Withholding judgement is appropriate when evidence is insufficient.
The Three Positions
Instead of only:
true / false
use:
- supported;
- refuted;
- not yet established.
This is useful for critical reading.
Worked Example: Advertisement
Claim:
“Nine out of ten users prefer our product.”
Burden questions:
- how many users?
- how selected?
- what question wording?
- who conducted the survey?
A number does not remove the need for evidence quality.
Worked Example: Testimonial
“This course changed my life.”
The testimonial is strong evidence about that person’s reported experience.
It is weak evidence for:
“The course will change everyone’s life.”
Burden rises with scope.
Worked Example: Source Criticism
Claim:
“This source is biased, so its data is false.”
The accuser now carries a burden:
- show the relevant bias;
- show how it affects the data or interpretation;
- compare independent evidence.
Bias may justify scrutiny, not automatic dismissal.
Burden in Comprehension
When a writer asserts:
“The scheme has transformed the neighbourhood,”
ask:
- what transformation?
- what evidence?
- what baseline?
- what alternatives?
This helps students distinguish rhetorical confidence from demonstrated support.
Burden in Argumentative Writing
Before each strong sentence, ask:
What evidence have I already given that earns this wording?
If the answer is none, either:
- add evidence;
- narrow the claim;
- mark it as hypothesis/possibility.
The Burden Audit
- Underline every claim.
- Label its type.
- Locate the evidence.
- Check whether the evidence matches the claim.
- Check whether the claim is stronger than the support.
- Identify unanswered challenges.
Questioning Without Burden-Shifting
Good challenge:
“What evidence supports that conclusion?”
Good reply:
provide evidence or narrow the claim.
Poor reply:
“Prove the opposite.”
That changes the subject of responsibility.
The Symmetry Test
Apply the same evidence standards to:
- claims you like;
- claims you dislike;
- your own argument;
- the opposing argument.
Burden of proof should not change merely because the conclusion is convenient.
Burden and Counterargument
A counterargument should not merely attack.
Strong structure:
opponent claim → fair paraphrase → burden gap → evidence/counterevidence → revised conclusion
Burden and Uncertainty
If support is partial:
use calibrated language:
- suggests;
- supports;
- may;
- under these conditions;
- insufficient evidence to conclude.
Uncertainty language is not evasion when the evidence is genuinely limited.
Secondary English Context
MOE’s Secondary English Language Syllabus 2020 emphasises critical interpretation, evidence use and purposeful argument. Burden-of-proof reasoning helps students evaluate persuasive texts and strengthen their own essays.

Common Burden-of-Proof Failure Modes
| Symptom | Problem | Repair |
|---|---|---|
| “Prove me wrong” | burden shifted | support original claim |
| Opponent cannot refute, therefore true | absence mistaken for proof | seek positive evidence |
| Counterclaim unsupported | two assertions | support both sides |
| Strong universal from one example | burden exceeds evidence | narrow scope |
| Forced yes/no conclusion | uncertainty ignored | allow “not established” |
Why Three Students Helps
One student makes the claim, one asks what burden the claim creates and the third decides whether the evidence satisfies that burden or whether the conclusion should be narrowed.
When Sengkang Families May Consider This Support
- Essay claims sound confident but unsupported.
- Discussion relies on “prove me wrong”.
- Students think lack of refutation makes a claim true.
- Counterarguments become opposing assertions rather than evidence-based replies.
What Progress Should Look Like
A stronger learner can identify who made the claim, state what evidence burden follows, reject burden-shifting, distinguish unsupported from refuted and calibrate conclusions when the available evidence does not justify certainty.
