3. 📖 Core Content
3.1 Intuition: What Is Critical Analysis?
Critical analysis means not believing everything you read. Instead of accepting a text at face value, you ask: Is this true? Is the evidence strong? Is the author biased? What is missing?
Think of it like detective work. You are investigating the text for clues, looking for what is hidden, and judging whether the case is solid.
Real-world context: We live in an age of information overload — fake news, biased articles, marketing disguised as information. Critical reading is not just an academic skill; it is essential for being an informed citizen and making good decisions.
3.2 The Critical Reading Framework
(Diagram)
| Question | What It Reveals |
|---|---|
| Who wrote this? | Author's expertise and potential bias |
| What is the main claim? | The argument being made |
| What evidence is provided? | The support for the claim |
| Is the evidence credible? | Trustworthiness of sources |
| What is missing? | What the author left out |
| Why was this written? | Purpose (inform, persuade, entertain) |
3.3 Analyzing Arguments
Every argument has three parts:
| Part | Definition | Example |
|---|---|---|
| Claim | The main point the author wants to prove | "Social media harms teenage mental health." |
| Evidence | The support for the claim | "A 2023 study found that teens who use social media 3+ hours daily have 2x higher depression rates." |
| Assumption | The unstated belief linking evidence to claim | "Exposure to curated content causes harmful social comparison." (not stated but necessary for the argument to work) |
Worked Example
"School uniforms should be mandatory because they reduce bullying. In schools that implemented uniform policies, reports of bullying decreased by 30%."
| Element | Identification |
|---|---|
| Claim | School uniforms should be mandatory |
| Evidence | Bullying decreased by 30% in schools with uniforms |
| Assumption | The decrease in bullying was CAUSED by uniforms (not other factors) |
3.4 Detecting Bias
Bias = a one-sided perspective that distorts the truth.
| Type of Bias | Description | Example |
|---|---|---|
| Confirmation bias | Only presenting evidence that supports one's view | A climate change skeptic only citing studies that question global warming |
| Selection bias | Choosing data/examples that support the argument | A company's review page showing only 5-star reviews |
| Framing bias | Presenting information in a way that influences perception | "We have a 95% success rate" rather than "5% of patients die." |
| Omission bias | Leaving out important information | An article about nuclear power mentioning accidents but not safety improvements |
Questions to Detect Bias
| Question | Example |
|---|---|
| Who is the author and what are their credentials? | A cigarette company executive writing about health risks of smoking? |
| Who funded this research? | A sugar industry-funded study claiming sugar is not linked to obesity? |
| What language is used? (emotional vs. neutral) | "Shocking new evidence" vs. "Recent research suggests" |
| What perspectives are missing? | An article about immigration without immigrant voices |
3.5 Evaluating Evidence
The CRAAP Test
| Criteria | Question |
|---|---|
| Currency | When was this published? Is the information up-to-date? |
| Relevance | Does this information relate to the topic? Who is the intended audience? |
| Authority | Who is the author/publisher? Are they qualified? |
| Accuracy | Is the information supported by evidence? Can it be verified? |
| Purpose | Why was this written? To inform? Persuade? Sell? |
Evidence Hierarchy
| Strength | Type | Example |
|---|---|---|
| Strongest | Peer-reviewed research | Double-blind clinical trials |
| Strong | Government/official data | Census data, WHO statistics |
| Moderate | Expert opinion | Professor's analysis |
| Weak | Anecdotal evidence | "My friend tried this and..." |
| Weakest | Personal opinion | "I think that..." |
3.6 Logical Fallacies
Logical fallacies are errors in reasoning that make an argument invalid.
Common Fallacies
| Fallacy | Definition | Example | Why It's Wrong |
|---|---|---|---|
| Ad Hominem | Attacking the person, not the argument | "You can't trust his climate science — he drives a car!" | Personal attacks don't disprove evidence |
| Straw Man | Misrepresenting the opponent's argument to make it easier to attack | "Opponents of free tuition want poor students to suffer." | Oversimplifies the opposing view |
| False Dilemma | Presenting only two options when more exist | "Either we ban plastic bags or the planet will die." | Ignores middle-ground solutions |
| Slippery Slope | Arguing that one step will lead to extreme consequences | "If we allow AI grading, soon robots will replace all teachers." | No evidence for the extreme outcome |
| Appeal to Authority | Using an authority figure in the wrong context | "A famous actor says this diet works!" | Actors are not nutrition experts |
| Circular Reasoning | The conclusion is also the premise | "This medicine works because it is effective." | No real evidence provided |
| Hasty Generalization | Drawing a conclusion from insufficient evidence | "I met two rude people from that city — everyone there is rude." | Sample too small |
| Correlation = Causation | Assuming because two things happen together, one causes the other | "Ice cream sales cause shark attacks." (both increase in summer) | Ignores third variables |
Fallacy Detection Exercise
"Students who use laptops in class perform worse. Therefore, laptops should be banned from all classrooms. If we don't ban them, soon no one will pay attention, grades will plummet, and the education system will collapse." Fallacies found:
- Hasty generalization — one study doesn't prove laptops cause poor performance
- Slippery slope — banning laptops → collapsing education system
- False dilemma — either ban laptops or accept total failure (ignoring middle options like monitored use)
3.7 Fact vs. Opinion vs. Inference
| Category | Definition | Example |
|---|---|---|
| Fact | Verifiable, objective | "The Earth orbits the Sun." |
| Opinion | Personal belief or judgment | "The Earth is the most beautiful planet." |
| Inference | Logical conclusion from facts | "Since Earth is the only known planet with life, conditions here must be unique." |
3.8 Annotated Example: Critical Analysis of an Article
Text:
"A new study from the University of Oxford shows that students who drink coffee score 15% higher on exams. The study followed 2,000 students over three years. Clearly, coffee is the secret to academic success. Every student should drink coffee before exams." Critical Analysis:
| Check | Finding |
|---|---|
| Author | Not named — could be anyone |
| Claim | Coffee improves exam scores |
| Evidence | Oxford study, 2,000 students, 15% higher scores |
| Assumption | Coffee CAUSED the higher scores |
| Bias | Coffee industry may have funded the study |
| Missing info | Did the study control for other factors (study time, sleep)? What kind of coffee? Who funded it? |
| Fallacy | Correlation = Causation. Students who drink more coffee might also study more. |
| Conclusion | The claim is too strong. The evidence shows correlation, not causation. |
3.9 Before/After: Naive vs. Critical Reading
| Naive Reading | Critical Reading |
|---|---|
| "The article says coffee improves grades. I should drink more coffee." | "The article shows a correlation between coffee and grades, but it doesn't prove causation. I need more information about the study." |
| "This website says the product is amazing. I should buy it." | "This is a product review site — likely biased. I should check independent reviews." |
| "The politician promises to fix everything. I will vote for them." | "Campaign promises are not evidence. I should check their track record and policy details." |
3.10 Key Concepts Summary Table
| Concept | Definition | Key Question |
|---|---|---|
| Claim | The main argument | "What is the author trying to prove?" |
| Evidence | Support for the claim | "What proof is offered?" |
| Assumption | Unstated belief | "What must be true for the argument to work?" |
| Bias | One-sided perspective | "What is the author's agenda?" |
| Fallacy | Error in reasoning | "Where does the logic break down?" |
| CRAAP Test | Evidence evaluation | "Is this source trustworthy?" |
| Fact | Verifiable | "Can this be proven?" |
| Opinion | Personal belief | "Is this someone's judgment?" |
4. Common Pitfalls
Pitfall 1: Accepting Everything at Face Value
- Mistake: "It was on the news / in a book / posted online, so it must be true."
- Why: We trust sources we are familiar with
- How to fix: Always ask: Who wrote this? Why? What evidence supports it? What is missing?
- Correct: Be skeptical. Verify claims against other sources.
Pitfall 2: Confusing Correlation with Causation
- Mistake: "More ice cream sold → more shark attacks. Therefore, ice cream causes shark attacks."
- Why: Humans naturally look for cause-effect relationships
- How to fix: Ask: Is there a third variable? (In this case: summer = more beach goers = more ice cream + more shark attacks)
- Correct: Correlation does NOT equal causation.
Pitfall 3: Letting Emotion Override Logic
- Mistake: Believing a story because it made you emotional
- Why: Emotional stories feel "true"
- How to fix: Separate emotional impact from factual accuracy. A moving story can still be false.
- Correct: "This story made me sad, but I need to verify its claims independently."
5. Practice Questions
Question 1
Identify the claim, evidence, and assumption:
"You should buy this laptop because it has the fastest processor on the market."
Click for answer
- Claim: You should buy this laptop.
- Evidence: It has the fastest processor.
- Assumption: A fast processor = the best laptop (ignores battery life, price, weight, etc.)
Question 2
Identify the logical fallacy:
"Either we build this new highway, or our city will be stuck in traffic forever."
Click for answerFalse Dilemma — presents only two extreme options. Other solutions exist (public transport, bike lanes, work-from-home policies, etc.).
Question 3
Apply the CRAAP test: You find an article claiming that chocolate cures cancer. It is published on a website called chocolatenews.com.
Click for answerCurrency: Check the date. Relevance: Claims about cancer treatment are important. Authority: SUSPECT — chocolatenews.com is likely biased (chocolate industry). Accuracy: Cross-check with medical sources (WHO, cancer research institutes). Purpose: Likely to sell chocolate, not to inform.
Question 4
Is this fact or opinion?
"The Earth's average temperature has risen by 1.1°C since the 19th century."
Click for answerFact — measurable, verifiable by scientific data.
Question 5
Detect the bias:
"Our product is loved by thousands of satisfied customers. Rated 5 stars by our verified purchasers!"
Click for answerBias: Selection bias — only showing positive reviews. "Verified purchasers" could mean selected users. No negative reviews shown. The company controls the narrative.
Question 6
Identify the fallacy:
"How can we trust your opinion on education policy? You don't even have children!"
Click for answerAd Hominem — attacking the person (not having children) instead of addressing their argument about education policy.
Question 7
Analyze this argument:
"Studies show that students in smaller classes perform better. Therefore, all classes should have no more than 15 students."
Click for answer
- Claim: All classes should have ≤15 students.
- Evidence: Studies show smaller classes improve performance.
- Assumption: The benefit of small classes justifies the cost of hiring more teachers/building more rooms.
- Missing: Cost analysis, feasibility, comparison with other interventions.
Question 8
What type of bias is this?
A news channel covers a protest and only interviews people who support the government's position.
Click for answerSelection bias / Omission bias — choosing which voices to include (only one side) and omitting the other perspective.
Question 9
Identify the straw man fallacy:
"People who support renewable energy want to shut down all fossil fuel plants tomorrow and leave everyone in the dark."
Click for answerStraw Man — misrepresenting the pro-renewable position. Most supporters advocate a gradual transition, not an immediate shutdown.
Question 10
Evaluate this evidence: "My uncle smoked for 40 years and lived to 90, so smoking isn't that harmful."
Click for answerWeak evidence — anecdotal (one person). Ignores the overwhelming statistical evidence that smoking causes disease. This is also a hasty generalization.
Question 11
Apply critical analysis to this headline:
"Study Finds That Students Who Use AI Write Better Essays"
Click for answerCritical questions:
- Who conducted the study? (Any conflict of interest?)
- How was "better" measured? (Grades? Originality? Speed?)
- What was the sample size?
- Did the study control for student ability?
- Who funded the research? (AI company?)
- What is NOT mentioned? (Potential downsides like reduced critical thinking?)
Question 12
Identify ALL fallacies in this short text:
"Everyone knows that video games cause violence. My friend's son plays video games and he got into a fight at school. If we don't ban video games, soon every child will be violent. People who defend video games just want kids to be violent."
Click for answer
- Hasty Generalization — one anecdote does not prove all video games cause violence.
- Slippery Slope — "if we don't ban them, soon every child will be violent."
- Straw Man — misrepresenting game defenders as wanting violence.
- Ad Hominem — attacking defenders instead of their arguments.
- "Everyone knows" — appeal to false consensus (bandwagon fallacy).
