What Will You Learn?

Critical thinkers don't just accept what they read - they ANALYZE it! Today you'll learn to break down arguments, evaluate evidence, spot logical fallacies, and identify bias. These skills help you make better decisions about what to believe.

The Three Parts of Any Argument: C.E.R.

Every strong argument has three essential components:

CLAIM

The main point or position the author argues

"What is the author trying to convince me?"

EVIDENCE

Facts, statistics, examples, or expert opinions that support the claim

"What proof does the author provide?"

REASONING

The logical explanation connecting evidence to the claim

"How does this evidence support the claim?"

Example: Analyzing an Argument

"Schools should start later for middle and high school students. Research from the American Academy of Pediatrics shows that teens need 8-10 hours of sleep, but their bodies naturally want to fall asleep later and wake up later than adults. When Seattle moved start times from 7:50 to 8:45 AM, students got 34 more minutes of sleep and had better attendance and grades. Since early start times fight against teen biology, later starts would improve student health and academic performance."

Component From the Argument
Claim Schools should start later for middle and high school students.
Evidence 1) Teens need 8-10 hours of sleep (AAP) 2) Seattle students got 34 more minutes of sleep 3) Better attendance and grades
Reasoning Early start times fight against teen biology, so later starts improve health and performance.

Evaluating Evidence: Is It Strong?

Not all evidence is created equal! Ask these questions:

Strong Evidence Weak Evidence
Specific facts and statistics Vague statements ("many people say...")
Expert opinions from qualified sources Opinions from unqualified sources
Recent, up-to-date information Outdated information
Evidence directly related to the claim Irrelevant facts that don't support the claim

Common Logical Fallacies (Flawed Reasoning)

A fallacy is an error in reasoning that makes an argument weak. Learn to spot these:

Bandwagon

"Everyone's doing it, so it must be right."

"All the cool kids have this phone - you should get one too!"

Ad Hominem (Personal Attack)

Attacking the person instead of their argument.

"Don't listen to her opinion on music - she's only 12!"

False Cause

Assuming one thing caused another just because they happened together.

"I got an A after eating pizza for dinner, so pizza makes me smarter!"

Either/Or (False Dilemma)

Presenting only two options when more exist.

"Either you support unlimited screen time or you hate technology."

Hasty Generalization

Drawing big conclusions from too little evidence.

"I met two unfriendly people from that school, so everyone there must be mean."

Appeal to False Authority

Using a celebrity or non-expert as proof.

"This famous actor says this diet works, so it must be true!"

Spotting Bias: Warning Signs

Bias is when an author favors one side without fairly considering other perspectives. Look for:

Author's Purpose Shapes Arguments

WHY an author writes affects WHAT they include and HOW they present it:

Purpose How It Affects Content
To Persuade Emphasizes supporting evidence; may downplay counterarguments; uses emotional appeals
To Inform Presents multiple perspectives; uses neutral language; focuses on facts
To Sell Highlights benefits; hides drawbacks; creates urgency or desire

Your Turn!

1. Identify the CLAIM in this argument:

"Homework should be limited to 30 minutes per night. Studies show excessive homework causes stress without improving learning. Students need time for physical activity, family, and sleep. Finland, which assigns minimal homework, consistently ranks among the top countries in education."

2. What logical fallacy is used here?

"You can't trust her opinion on the new cafeteria menu - she's a picky eater who doesn't even like pizza!"

3. Which piece of evidence is STRONGEST for the claim "Video games can have educational benefits"?
4. What sign of BIAS can you identify in this statement?

"The reckless decision to cut art programs will devastate students' creativity and destroy their futures."

5. An advertisement says: "9 out of 10 dentists recommend our toothpaste!" What questions should you ask to evaluate this evidence?
