Logical Fallacies Detection Guide
Use this handout to help ākonga recognise weak reasoning, emotional manipulation, and argument moves that sound persuasive without actually being sound. The goal is not to “win” an argument, but to think more carefully and argue with integrity.
Free reasoning scaffold, premium adaptation path
This handout is ready to print and use as-is. If you want a version built around current political debate, local issues, AI-generated claims, or your own class texts, Te Wānanga can adapt the examples while keeping the reasoning frame intact.
- Swap in examples from social media, class debates, or current events.
- Generate junior or senior versions with lighter or denser analytical language.
- Save the adapted version and reopen it later in My Kete or Creation Studio.
Kaiako planning snapshot
- Use length: 15-25 minutes for a quick analysis round, or a full lesson if students revise and improve arguments.
- Grouping: Whole-class modelling first, then pairs or small groups to detect fallacies in sample claims.
- Prep: Bring one speech extract, article quote, or social post that contains weak reasoning students can unpack together.
- Teaching move: Emphasise that naming a fallacy is not enough — students should also explain what stronger reasoning would look like.
Resources already provided
- Common fallacy quick-reference
- Detection questions
- Example and repair prompts
- Self-check for reviewing arguments
- Discussion/writing sentence starters
- Curriculum companion for planning/reporting
If the lesson asks students to identify flawed reasoning or improve an argument, the main scaffold is already here so kaiako are not left inventing examples or prompts.
Ngā Whāinga Akoranga / Learning Intentions
- We are learning how to recognise common patterns of weak reasoning.
- We are learning how to explain why a claim is flawed, not just label it.
- We are learning how to rebuild an argument so it is fairer and stronger.
Paearu Angitu / Success Criteria
- I can identify at least one logical weakness in an argument.
- I can explain what makes the reasoning weak or manipulative.
- I can suggest how the claim could be improved using stronger evidence or reasoning.
Curriculum integration / Te Marautanga alignment
Use the companion page to make the curriculum intent explicit around analysing argument, participating in discussion, and making reasoned, evidence-based responses in English and inquiry-rich contexts.
Why this matters in Aotearoa
Arguments in public life often sound certain while hiding weak evidence, false binaries, or attacks on people rather than ideas. In Aotearoa, students need tools that help them navigate debate with mana, challenge poor reasoning, and avoid reproducing harmful stereotypes or simplistic narratives.
Common fallacies to watch for
Ad hominem
The speaker attacks the person instead of addressing their idea or evidence.
Straw man
The argument misrepresents the other side so it is easier to attack.
False dilemma
The speaker pretends there are only two options when more possibilities exist.
Appeal to emotion
The claim relies on fear, pity, outrage, or guilt instead of sound evidence.
Hasty generalisation
A broad conclusion is drawn from too little evidence or one striking example.
False cause
Two things happen together and the speaker assumes one automatically caused the other.
Questions to ask when a claim sounds strong
- What is the actual claim being made?
- What evidence supports it?
- Is the argument attacking an idea, or attacking a person/group?
- Is the speaker leaving out other possible explanations or options?
- Would the claim still stand if the emotional wording was removed?
Detect and repair scaffold
- Claim: _________________________________________________
- Possible fallacy: ______________________________________
- Why it is weak: _______________________________________
- What evidence is missing: ______________________________
- A stronger version of the argument would: ________________
Sentence starters for oral or written response
- This argument is weak because...
- The speaker relies on ___ instead of evidence when...
- A stronger argument would include...
- This claim leaves out...
- The reasoning would be more convincing if...
Self-check before I use or repeat a claim
- I can identify the main claim being made.
- I can explain whether the reasoning is strong or weak.
- I can point to the evidence being used — or notice that it is missing.
- I am not repeating a claim just because it sounds confident or emotional.
- I can suggest a fairer or better-supported alternative.
Tautoko / Support
- Teach two or three high-frequency fallacies first before showing the full set.
- Use a shared class example so students can practise the language together.
- Let students explain their thinking orally before writing.
Whakawhānui / Extension
- Ask students to find fallacies in contemporary media or political language.
- Have learners revise a weak argument into a stronger one.
- Compare how different fallacies affect trust in the speaker.

Social Sciences — Tikanga ā-Iwi
Level 3–4: Investigate social, cultural, environmental, and economic questions; gather and evaluate evidence from diverse sources; communicate findings and reasoning clearly for different audiences and purposes.

Level 3–4: Read, interpret, and evaluate information texts; write clearly and purposefully for specific audiences; apply critical thinking skills to evaluate sources and construct well-reasoned responses.
Aronga Mātauranga Māori
This resource sits within a kaupapa that recognises mātauranga Māori as a living knowledge system with its own frameworks, values, and ways of understanding the world. The New Zealand Curriculum calls for learning that reflects the bicultural partnership of Te Tiriti o Waitangi, which means every subject area has an obligation to engage authentically with Māori perspectives — not as cultural decoration but as substantive contributions to how we understand our topics. The concepts of manaakitanga (care for others), kaitiakitanga (guardianship), whanaungatanga (relationship and belonging), and tino rangatiratanga (self-determination) provide a values framework applicable across all learning areas, and all are relevant to the work in this handout.

📋 Teacher Planning Snapshot
Ngā Whāinga Ako — Learning Intentions
Students will engage with this resource to develop te whakaaro māramatanga — critical and analytical thinking skills — examining claims, evaluating evidence, identifying bias, and constructing reasoned arguments. This unit frames critical thinking through both Western analytical traditions and the kōrero-based reasoning of Te Ao Māori.
Ngā Paearu Angitū — Success Criteria
- ✅ Students can identify a claim, evaluate the evidence supporting it, and detect potential bias or fallacy.
- ✅ Students can construct a reasoned argument using evidence, acknowledging counter-perspectives.
Differentiation & Inclusion
Scaffold support: Provide argument frames (claim → evidence → reasoning → counter-argument) for entry-level access. Use structured controversy activities where students argue assigned positions. Offer extension tasks requiring students to analyse a real media article or policy document using the lesson's critical framework.
ELL / ESOL: Pre-teach argumentative language structures ("I argue that…", "The evidence suggests…", "However, one might counter…"). Allow oral argument as a first step before written production. Sentence frames and argument maps lower the language barrier while maintaining cognitive demand.
Inclusion: Structured debate and discussion formats benefit all learners — particularly neurodiverse students who thrive with explicit rules and clear roles. Affirm that disagreement done respectfully is a high-value academic and civic skill. Allow quiet processing time before group discussion. Offer written alternatives for students who find oral argument challenging.
Mātauranga Māori lens: Te whakaaro māramatanga — enlightened thinking — reflects a long tradition of reasoned debate in Te Ao Māori. The whare (meeting house) is a place of kōrero, where multiple perspectives are heard before decisions are made. Tikanga requires that arguments be made with integrity and respect (mana). Māori oratory (whaikōrero) is a sophisticated critical tradition — whakataukī encode compressed wisdom that often challenges surface-level thinking.
Prior knowledge: Best used within a sequence building critical thinking skills progressively. No specialist knowledge required for entry-level engagement with structured tasks.
Curriculum alignment
- Do — Social Studies: Explore perspectives, use evidence to form conclusions, and share ideas — compare viewpoints, evaluate claims, and present reasoned arguments.
- Speaking, Writing, and Presenting: Construct and deliver clear, reasoned arguments drawing on evidence and acknowledging multiple perspectives.
