4-6 of 12 Popular Logical Fallacies

Abstract 

Master slippery slope arguments, appeals to authority, and emotional manipulation. These skills will boost your critical thinking.

In everyday arguments, people don't always play fair. Sometimes they use tricks that sound convincing but fall apart when you look closer. We call these logical fallacies, and recognizing them gives you a huge advantage. Let's explore three more common ones that you'll see all the time.

Slippery Slope

Sometimes people call it the domino effect. A slippery slope fallacy claims that a single action will lead to bad outcomes. People claim this without any proof that the subsequent events will actually occur. It's like saying if you push one domino, a hundred others must fall, but there's no proof those other dominoes even exist.

Example

Your parents say, "If we let you stay out until 11 PM on weekends, next you'll want midnight, then 1 AM, and soon you'll be staying out all night and failing school."

This assumes every step must follow the last. It doesn’t account for the fact that you can stay out until 11 PM without things getting chaotic.

How to Win

Break the chain of their argument. Take their concerns one at a time. You could say something like:

"Because I want to stay out until 11 on Saturdays doesn't mean I'll keep asking for later and later curfews. I'm only asking for this one change. My school grades are good, and I've proven I'm responsible."

By addressing each worry, we show that their fear of losing control isn’t genuine. You can also mention that many responsible teenagers have later curfews and still do well in school.

Appeal to Authority: Because Someone Famous Said So

Have you ever heard someone say, "It's true because an expert said so"? That's an appeal to authority. It's when a person tries to win an argument by pointing to someone important or famous instead of giving you the real facts. Being an authority doesn't mean someone is always right. And even a true expert can be wrong about things outside their field.

Example

"LeBron James says this cryptocurrency is the future of money, so we all should buy some."

In this case, someone asks you to believe in something not because of proof, but because a famous athlete said it.

LeBron is a fantastic basketball player, but that doesn't make him a financial expert. We must give his opinion on cryptocurrency careful consideration before deeming it correct.

How to Win

Don't trust someone because they are famous. Stop and ask, "Why should they?"

For example, if LeBron James tells you to invest in cryptocurrency, you could say: "LeBron is an amazing basketball player. But what does that have to do with cryptocurrency? What proof does he have that it's a good idea?"

This changes the talk from "a famous person said so" to "show me the facts." People who actually know what they're talking about can give you good reasons and real information to support their claims. They won't say, "Trust me, I'm an expert." They'll be able to explain why they're right.

Appeal to Emotion: Feelings Over Facts

Sometimes in an argument, people will try to get you to agree by making you feel something instead of giving you real proof. They might try to scare you, make you feel sympathy for them, or get you filled with excitement. Your feelings matter, but they don't count as evidence. The goal of this trick is to distract you with emotion, which prevents a close examination of the facts.

Example

During a debate about a new tax for school technology, someone says, "How can you be so heartless? Don't you care about giving every student the same opportunities? Some kids can't afford laptops!"

This makes people feel guilty for questioning the tax. They may have real concerns about whether it works or how they use the funds.

How to Win

First, show them you understand their point. Then, bring the talk back to what's practical. You might say:

"I agree, every kid should get a fair shot. That's the goal. But before we increase taxes, we should explore all ways to pay for them. Could we apply for grants or even find used laptops through a donation drive? And then there is the cost of maintaining them?"

When you do it this way, it's clear you're on the same team. You're being practical. Being calm and asking good questions shows you're looking for a real solution, not going with the moment.

Putting It All Together

These three fallacies—slippery slope, appeal to authority, and appeal to emotion—occur with great frequency. Politicians use them. Advertisers use them. Your friends likely use them without awareness. But they all have the same weakness: they avoid dealing with facts and logic.

When you recognize these patterns, you gain power in any discussion. You can steer conversations back to evidence and reason. You will make better choices when you engage in clear thinking. Do not let fear, guilt, or blind trust in authority control you.

Practice spotting these fallacies in conversations, news articles, and social media. The more you recognize them, the sharper your thinking becomes—and the harder you are to fool.
