Guide to Debating

Debating is an important skill in many aspects of life, from winning political seats, to negotiating new contracts, to personal development.


What is debating?

A debate is a structured contest over an issue or policy. There are two sides - one supporting, one opposing.

Benefits of debating include:

  • Allowing you to think about aspects and perspectives you may not have considered.

  • Encourages you to speak strategically.

  • Improving public speaking skills.

  • Learning how to create a persuasive argument.

  • When you have to argue against your personal view you realize that there are two sides to the argument.



Debate structure

There are multiple formats a debate can follow, this is a basic debate structure:

  • A topic is chosen for each debate - this is called a resolution or motion. It can be a statement, policy or idea. The motion is usually a policy which changes the current state of affairs or a statement which is either truth or false. The motion typically starts with "This House..."

  • There are two teams of three speakers:

  • The Affirmative team support the statement

  • The Negative team oppose the statement

  • Sometimes you will be asked to take a position in the debate but in other debates you will be allocated your position.

  • Teams are provided with time to prepare - usually one hour

  • Each speaker presents for a set amount of time

  • Speakers alternate between the teams, usually a speaker in the Affirmative team starts, followed by a Negative speaker, then the second Affirmative speaker presents, followed by the second Negative speaker etc.

  • The debate is then judged.

  • There may be an audience present but they are not involved in the debate

Once you have learned how to debate in one format you can easily switch to another.



Roles of the speakers

Each speaker must typically do the following:


First Affirmative

  • Contextualize the debate - clearly set out your team's interpretation of the topic and the significant issues they disagree with.

  • Provide definitions if necessary.

  • Outline the team line and the team split - this is where you outline your team's case and summarize the way your arguments have been divided between your speakers.

  • Provide 2-3 arguments supporting the motion.

First Negative

  • Re-contextualize the debate and resolve any definitional issues - if you have disagreements with the definition given by the Affirmative these must be handled immediately. If you want to challenge the definition then you must prove that you have the most appropriate definition. There are three main steps in a definitional challenge:

  1. Clearly state your definition

  2. Provide your arguments as to why this is the superior definition

  3. Rebut the Affirmative's arguments supporting their definition


  • Outline a team line and team split.

  • Rebut the arguments made by the First Affirmative.

  • Deliver 2-3 arguments against the motion.

Second Affirmative

  • If needed, resolve any definitional issues.

  • Rebut the First Negative's arguments.

  • Deliver 2-3 arguments supporting the motion.

Second Negative

  • If needed, resolve any definitional issues.

  • Rebut the arguments made by the Affirmative team up to this point, with a focus on the Second Affirmative's arguments.

  • Deliver 2-3 arguments against the motion.

Third Affirmative

  • Rebut specific issues raised by Second Negative and defend any other important attacks on your team's case.

  • Conclude your speech with a brief summary (1-2 minutes) of your team's case. You should include the key issues which you and the Negative team disagreed on during this.

  • You can introduce new material but this is interpreted as poor team planning.

Third Negative

  • This is the same structure as the Third Affirmative.

There are many variations of the three against three debate, a commonly known one is Points of Information. This is used a lot in university debates. During a speech the opposition is allowed to ask a question or make a point.


They stand up and say "point of information" or "on that point" etc. The speaker can choose to accept or reject the point. If accepted, the point of information can last around 15 seconds and the speaker can ask for it to stop at any time.



Debate definitions

Younger debaters tend to waste time defining terms so you must first decide whether you need to define a term. Ask yourself: will my speech be confusing if I don't define this term? Could the opposition misinterpret what I mean without a definition? For example, the motion could be "we should ban plastic straws". It's clear what "plastic straws" are but what does "ban" mean?



Two factors which determine the definition of the debate:

1. Context - what is happening in the area that relates to this issue? For example, maybe the government of a country is debating banning smoking in public buildings and you decide to define the term "passive smoking" during the debate. If a significant event related to the topic has occurred then it should be the focus of the debate, for instance, a shocking report may have recently been revealed in the media showing the widespread effects of second-hand smoking.

2. Spirit of the motion - topics are chosen for a reason so what sort of debate was imagined when the topic was chosen? Looking at the spirit of the motion will ensure that you pick a definition that will produce a well-balanced and important debate.

If the topic is vague then you will have more choice of definitions. You have a duty to pick a clear definition and one that will create a good debate. If not, this may cause a definitional challenge which will ruin the debate and frustrate the judges.

For example, the topic may be "we spend too much money on the stars". Stars can refer to celebrities or astronomy so you need to choose a definition.

  1. Look at the context and see if there has been a recent significant event related to either topics - the media is the best place to look.

  2. Then apply second test - which definition will lead to the best debate, which will be more interesting and debatable?

If one answer passes both tests then that's your definition. If they tie then either is a good definition.

When providing your definition explain the context used to form the definition. This is important because your understanding of the context may be different from others due to various factors, such as, religion, culture, gender etc.



Basic argument structure

There are various ways of dividing up cases according to groups of arguments, such as, social/economic/political etc. You could assign each speaker to handle a group.

Place the most important arguments first, for example, "The media has more influence on self-esteem than anybody else. This is true for three reasons. Firstly (most important argument)… Secondly…, Thirdly (least important argument)..."

To structure an argument follow these steps:

  1. Claim - present your argument in a clear statement. This claim is one reason why you're in favor of/against the motion.

  2. Evidence - the evidence supporting your claim, such as, statistics, references, quotes, analogies etc.

  3. Impact - explain the significance of the evidence - how does this support your claim?


Rebuttal

Arguments are weakest at the evidence stage as it's easy to argue against, for example, the evidence may consist of isolated examples or there may be counter evidence. But it's not a good technique because the opposition can provide more evidence or rebut your criticisms.

It's difficult to rebut claims because they are usually reasonable but if you can attack a claim then that speaker's whole argument falls apart. So if you think a claim is vulnerable then rebut it but you will need a strong explanation to show why it doesn't matter.

There are common flaws you can look for to form a rebuttal:


1. False dichotomy - this is where the speaker is trying to falsely divide the debate into two sides even though there are more alternatives than they state. It's likely the speaker is doing this on purpose but in some cases they do not understand the debate.


2. Assertion - this is when a speaker presents a statement which isn't actually an argument because there is no reason to believe that the statement is valid. It may just be an assumption. You can point out that there has not been enough examination to prove this validity and then give a reason why the assertion is (probably) not valid.


3. Morally flawed - arguments can be morally flawed, for example, "All criminals given a prison sentence should be given the death penalty instead, this will save the country money and space." What has been argued is true but it's clearly morally flawed.


4. Correlation rather than causation - a speaker may suggest a link between two events and suggest one led to the other. But the speaker may not explain how one caused the other event which can make an argument invalid.


5. Failure to deliver promises - sometimes a speaker might fail to complete a task they promised to deliver. For instance, they may state that they will provide evidence supporting a certain claim but they may lose track of what they have said and not actually do this.


6. Straw man - the opposing team introduces an argument and then rebuts it. They may use an extreme example of your proposal or perhaps they were hoping that you would make this argument.


7. Contradiction - an argument the other team presents may contradict one of their previous arguments. You must point out that the arguments cannot be true simultaneously and then explain how this reduces their case's credibility.


8. Compare the conclusion to reality - think "what would happen if what they (the other team) are suggesting is implemented right now?" This usually shows that it's more complicated than they have suggested and the changes can cause secondary problems.



Important skills for debating

To meet the judges criteria you will have to develop certain skills, consider the following:

  • You points must be relevant to the topic.

  • Provide evidence whenever you can and not your personal opinion.

  • You must put aside your personal views and remain objective when you debate so your argument remains logical. You can be passionate about a topic but interest can turn into aggression and passion can turn into upset.

  • Consider the audience's attention span - make it interesting, for example, don't just present lots of complicated statistics.
