SECTION 1
Why We Need to Check Facts in Speeches
Throughout history, people in power have tried to convince others through speeches. Sometimes these speakers tell the truth, but other times they stretch facts or even lie to make their point stronger. The ability to fact-check speeches became especially important as newspapers, radio, and television allowed politicians to reach millions of people at once.

Today, we're flooded with information from speeches, social media posts, and news reports. Learning to identify and evaluate claims, reasons, and evidence helps us become smarter consumers of information and protects us from being misled by false or exaggerated statements.
SECTION 2
The Three Building Blocks of Arguments
Every persuasive speech is built from three main parts that work together like pieces of a puzzle. Understanding these building blocks helps us see how speakers try to convince their audience and whether their arguments actually make sense.
Claims
Reasons
Evidence
Think of these three elements like a house being built. The claim is what you want to build ("I want a house here"). The reasons are your plan ("because this spot has good drainage and sunlight"). The evidence is your proof ("here are the soil tests and weather data that show this").

SECTION 3
How Claims, Reasons, and Evidence Connect
When fact-checking a speech, you're looking for this logical flow from claim to reason to evidence. Sometimes speakers skip steps or provide weak evidence. Other times they make claims without giving any reasons at all. Learning to spot these missing pieces helps you evaluate whether an argument is trustworthy.
Good speakers make it easy to follow their logic by using signal words like "because," "since," "according to research," and "for example." These phrases help you identify when they're moving from their claim to their reasons to their supporting evidence.
SECTION 4
The Fact-Checking Process
Fact-checking isn't just about finding mistakes. It's a systematic process that helps you understand and evaluate arguments. Professional fact-checkers follow specific steps to make sure they're being fair and thorough when analyzing speeches and written arguments.
Remember that fact-checking isn't about proving someone wrong—it's about finding the truth. Sometimes you'll find that a claim is completely accurate. Other times you'll discover it's partially true but missing important context. The goal is to help people make informed decisions based on reliable information.
SECTION 5
Different Types of Evidence to Evaluate
Not all evidence is created equal. When speakers support their claims, they use different types of evidence that vary in strength and reliability. Learning to recognize these types of evidence helps you judge how convincing an argument really is.
| Evidence Type | What It Is | Strengths | Weaknesses |
|---|---|---|---|
| Statistics & Data | Numbers, percentages, survey results from studies or government reports | Objective, measurable, can be verified by checking original sources | Can be outdated, taken out of context, or from biased studies |
| Expert Testimony | Quotes or opinions from people with special knowledge or training | Based on years of study and experience in the field | Experts can disagree; some may have conflicts of interest |
| Historical Examples | Events from the past used to show patterns or predict outcomes | Well-documented, can show cause-and-effect over time | Past events may not apply to current situations |
| Personal Stories | Individual experiences or anecdotes that illustrate a point | Easy to understand, creates emotional connection with audience | One person's experience may not represent everyone's |
Comparing different types of evidence commonly used in speeches and arguments
The strongest arguments combine multiple types of evidence. For example, a speaker might use statistics to show the size of a problem, expert testimony to explain why it's happening, and personal stories to help the audience understand how it affects real people. When fact-checking, look for this variety—arguments that rely on just one type of evidence are usually weaker.
RED FLAGS TO WATCH FOR
SECTION 6
Fact-Checking a School Speech
Let's practice fact-checking by analyzing a speech from a student running for class president. We'll go through each step of the process to see how claims, reasons, and evidence work together—and what to do when they don't.
Sample Speech Excerpt
- 1
Step 1 — Identify the Main Claim
Speech text: "Our school needs a longer lunch period. Studies prove that students who have more time to eat perform better in afternoon classes. In fact, 95% of students at schools with 45-minute lunches get higher test scores."Main Claim: "Our school needs a longer lunch period." - 2
Step 2 — Locate the Reasons and Evidence
The speaker gives one reason: "students who have more time to eat perform better in afternoon classes." For evidence, they cite "studies" and claim "95% of students at schools with 45-minute lunches get higher test scores."Reason: More eating time → better performance. Evidence: Unnamed studies, 95% statistic - 3
Step 3 — Research the Claims
When we research "lunch length and academic performance," we find some studies showing benefits of longer lunch breaks, but they focus on physical activity and social time, not just eating. We cannot find the specific "95%" statistic cited anywhere in educational research.Research Finding: Some support exists, but the specific statistic appears to be false. - 4
Step 4 — Evaluate the Overall Argument
The general idea has some merit—longer lunch periods can benefit students. However, the speaker used a made-up statistic and oversimplified the research. The reason given was too narrow (focusing only on eating time) and the evidence was unreliable.Final Rating: MIXED—The claim has some valid support, but uses false evidence.
This example shows why it's important to check specific facts, not just general ideas. The student's claim about longer lunch periods might be worth considering, but the made-up statistic damages their credibility. Good fact-checking helps separate legitimate arguments from those that rely on false or misleading information.
SECTION 7
Judging Source Reliability
When fact-checking, you'll need to decide which sources to trust. Not all websites, articles, or experts are equally reliable. Learning to evaluate source quality is crucial for accurate fact-checking and helps you avoid spreading misinformation yourself.
| Source Type | Reliability Level | What to Look For |
|---|---|---|
| Government Agencies (CDC, Census Bureau, NASA) | Very High | Official data collection methods, peer review processes, clear methodology |
| Academic Journals & University Research | Very High | Peer-reviewed studies, detailed methods, citations to other research |
| Established News Organizations (AP, Reuters, BBC) | High | Professional journalists, fact-checking standards, corrections when wrong |
| Expert Interviews & Professional Organizations | Medium-High | Relevant credentials, no conflicts of interest, consensus among experts |
| Personal Blogs & Opinion Websites | Low | Author's expertise, citations to reliable sources, clear bias disclosure |
| Social Media Posts & Anonymous Sources | Very Low | Multiple independent confirmations, links to verified sources |
Guide to evaluating source reliability for fact-checking purposes
KEY TAKEAWAY
Remember to check the date of your sources too. A news article from 2015 about smartphone usage might not be accurate today. Government statistics from several years ago may be outdated. Always look for the most recent reliable information when fact-checking current claims.
SECTION 8
Beyond Basic Fact-Checking
As you become more skilled at fact-checking, you'll start noticing more subtle problems with arguments. These advanced techniques help you spot when speakers use true facts but present them in misleading ways, or when they make logical errors that weaken their arguments.
| Advanced Issue | What It Looks Like | How to Spot It |
|---|---|---|
| Cherry-Picking | Using only the data that supports your point while ignoring contradicting evidence | Look for missing context, check if other studies show different results |
| False Correlation | Claiming that because two things happen together, one must cause the other | Ask if there could be other explanations for the connection |
| Outdated Information | Using old statistics or research as if they're still current | Always check the date of studies and data cited in arguments |
| Emotional Manipulation | Using scary stories or extreme examples instead of typical evidence | Look for broader data that shows whether the examples are representative |
These advanced skills take practice to develop. Professional fact-checkers spend years learning to spot these subtle forms of misleading information. The key is to stay curious and skeptical—even when information comes from sources you trust, it's worth double-checking important claims that seem surprising or too good to be true.

SUMMARY
Mastering Fact-Checking Skills
Summary
Fact-checking speeches requires understanding how claims, reasons, and evidence work together to create convincing arguments. Every persuasive speech contains a main claim (what the speaker wants you to believe), supported by reasons (why you should believe it), and backed up with evidence (proof that makes the reasons believable). The four-step fact-checking process—identify, locate, research, and evaluate—helps you systematically analyze any argument you encounter.
Strong fact-checking skills protect you from misinformation and help you make better decisions. Remember to evaluate source reliability by checking credentials, dates, and potential bias. Watch for red flags like unnamed studies, emotional manipulation, and cherry-picked data. Most importantly, approach fact-checking with curiosity rather than just trying to prove someone wrong—your goal is to find the truth and help others make informed decisions based on reliable information.
