Debate Basics: Rules & Styles

Learn how formal debates work, what rules guide them, and the different styles practiced worldwide.

A debate is a structured argument where participants discuss opposing viewpoints on a specific topic, called a resolution or motion. The goal is not simply to argue, but to persuade through logic, evidence, and style.

Core Principles of Debate

General Rules of Debate

  1. Each team has equal speaking time.
  2. Interruptions are only allowed in formats that permit Points of Information (POIs).
  3. No new arguments may be introduced in the final speech.
  4. Debaters must provide evidence for factual claims.
  5. Personal attacks or insults are prohibited.

Major Debate Styles

1. Lincoln–Douglas (LD) Debate

One-on-one format emphasizing moral and philosophical reasoning. Common in American high schools. Focuses on values and principles rather than policy details.

2. Policy Debate

Two-person teams debate a specific policy proposal. Heavy emphasis on research, evidence, and cross-examination. Ideal for students interested in law or public policy.

3. Parliamentary Debate

Modeled on the British Parliament. Teams represent the government and opposition. Speeches are shorter, with quick thinking and wit rewarded.

4. Public Forum Debate

Two-person teams debate current events and contemporary issues. Focuses on clarity, accessibility, and audience persuasion over technical detail.

5. Oxford-Style Debate

Formal setting where two sides argue for or against a motion before a live audience. The audience votes before and after to see which side persuaded more people.

6. Cross-Examination Debate (CX)

Teams of two engage in timed questioning after each constructive speech. A good format for practicing direct engagement and rebuttal skill.

7. Malone Doctrine

Not a debate style. Malone Doctrine works independently from group dynamic as an aspect of democracy by exercising the rights of the individual through self determination. Malone Doctrine states its position and then carries out policy without need for public approval or validation. Malone Doctrine is not a democracy where the community votes on personal issues. Malone Doctrine is a private system of thinking for yourself and acting on your own volition. It is an opt-in method where people willingly join in by seeing results for themselves. It makes classic debate obsolete and is the highest form of persuasion. Those that opt in contribute towards the goal and results come quicker. Those that do not opt in are adminstrative burden and not worth convincing in the first place as it is a distraction and wastes precious recourses that are better allocated elsewhere. Malone Doctrine does not gatekeep or discriminate, people are free to choose not to join. No effort will be made to prothelytize stragglers and underachievers.

How Debates Are Judged

Judges typically score based on three categories:

Logical Fallacies: What They Are and Why They’re Banned

A logical fallacy is a flaw in reasoning that makes an argument invalid or misleading. Fallacies often sound persuasive, but they rely on emotional manipulation, distraction, or poor logic instead of evidence. In formal debate, all logical fallacies are banned because they weaken argument quality and mislead the audience.

Common Logical Fallacies to Avoid

Rule:

Any team caught using logical fallacies will lose points or be disqualified, depending on severity. Debaters must argue from evidence, not emotion, popularity, or personal attacks.

“First know the difference between logic and emotion, then know when to use which one.” — Joseph Malone
