Logical Fallacy Quick Reference
These are the reasoning mistakes that show up in almost every heated argument. Learn to spot them in what other people say and in your own thinking.
Ad Hominem
Attacking the person instead of their argument. "You are too young to understand" does not address the point being made.
Straw Man
Misrepresenting someone's argument to make it easier to knock down. "So you want to ban all cars?" when the other person suggested better buses.
Appeal to Authority
Claiming something is true because an expert said it, without checking whether that expert is relevant to the topic.
False Dilemma
Presenting only two options when more exist. "You are either with us or against us" ignores every middle ground.
Slippery Slope
Arguing that one small step will inevitably lead to an extreme outcome without showing how each step follows.
Circular Reasoning
Using the conclusion as evidence. "This policy is fair because it is the right thing to do" goes nowhere.
Anecdotal Evidence
Using a personal story or one example to override data. "My grandfather smoked and lived to 95" does not disprove health research.
Begging the Question
Assuming the thing you are trying to prove is already true. Hidden in the premises, not stated openly.

Debate Behaviors That Push People Away
Even with perfect arguments, certain habits will lose your audience. Watch for these in yourself.
Talking over people
Let the other person finish. Interrupting signals that you care more about winning than understanding.
Raising your voice
Louder does not mean stronger. A calm tone makes people more willing to listen to your actual points.
Refusing to concede anything
Admitting a small point the other side makes shows confidence, not weakness. Nobody wins 100 percent.
Making it personal
Comments about intelligence, age, or background shut down conversation. Stay on the topic.
Using "always" and "never"
Absolute statements are easy to knock down. "Often" and "in many cases" are harder to attack and more honest.
Straw-manning on purpose
Deliberately twisting someone's point to beat it is dishonest. Engage with their strongest version instead.
Common Questions
Can I use this for school debate practice?
Yes. The structured format works well for practice rounds. Print the prep sheet and use it as a cheat sheet during prep time.
How are the arguments chosen?
Arguments are selected based on how commonly they appear in public discourse and how well they hold up to basic scrutiny. The goal is to show the strongest version of each side, not the weakest.
What if my topic is not in the library?
Type it into the input field at the top. The sorter will generate a basic pro/con framework and fallacy watch list based on common patterns for similar topics.
Is there a way to share a topic with someone?
Yes. Click the share button on any topic to copy a link with the topic encoded in the URL. When they open it, that topic loads automatically.
Does this tell me who won the argument?
No. This gives you the raw materials. How you present them and how your audience responds is up to you. The goal is clarity, not a trophy.
