1 of 3

• LD resolutions focus on philosophical, ethical, and moral issues rather than specific policies
• Debaters must argue for or against the resolution based on underlying values and principles (justice, equality, individual rights)
• Resolutions often involve weighing competing values and determining which should take precedence in a given situation

One-on-one debate format

• LD debates feature two debaters, one affirmative and one negative, arguing directly against each other
• The one-on-one format allows for more direct engagement and refutation compared to team-based debate formats
• Debaters must be prepared to both present their own arguments and respond to their opponent's case

Typical LD debate structure

Six minute affirmative constructive

• The affirmative debater begins with a six-minute speech presenting their case in support of the resolution
• This speech introduces the key arguments, values, and evidence that form the basis of the affirmative position
• The affirmative constructive sets the foundation for the rest of the debate and frames the discussion

Three minute cross examination periods

• After each constructive speech, the opposing debater has three minutes to ask questions and clarify arguments
• Cross-examination allows debaters to expose weaknesses, gain admissions, and set up future arguments
• Effective cross-examination requires strategic questioning and the ability to think on one's feet

Seven minute negative constructive

• The negative debater presents a seven-minute speech challenging the affirmative case and presenting their own arguments
• The negative constructive may involve direct refutation, presenting counterarguments, or proposing alternative value frameworks
• This speech is crucial for establishing the negative's position and undermining the affirmative's case

Four minute rebuttal speeches

• Each debater has a four-minute rebuttal speech to respond to their opponent's arguments and reinforce their own case
• Rebuttals involve identifying and addressing the key points of clash, prioritizing arguments, and crystallizing the debate
• Effective rebuttal requires adaptability, strategic decision-making, and the ability to weigh competing arguments

Three minute affirmative rejoinder

• The affirmative has a final three-minute speech, the rejoinder, to respond to the negative's case and summarize their position
• The rejoinder is the last opportunity for the affirmative to leave a lasting impression on the judge and solidify their arguments
• This speech should focus on the most important issues in the debate and clearly articulate why the affirmative should win

Roles and responsibilities of debaters

Affirmative case for the resolution

• The affirmative debater must present a coherent, logical case in support of the resolution
• This involves defining key terms, establishing a clear value framework, and presenting arguments that link the resolution to the chosen values
• The affirmative has the burden of proof to demonstrate that the resolution is true or beneficial based on the values being considered

Negative case against the resolution

• The negative debater must challenge the affirmative case and present arguments against the resolution
• This can involve direct refutation of the affirmative's arguments, presenting counterexamples, or proposing alternative value frameworks
• The negative should also offer reasons why the resolution is false, harmful, or less desirable than the alternative

Preparing for an LD debate

Researching the resolution

• Debaters must thoroughly research the resolution to understand its philosophical implications and real-world applications
• This involves studying relevant literature, analyzing examples and case studies, and considering various perspectives on the issue
• Effective research helps debaters construct well-supported arguments and anticipate their opponent's strategies

Constructing logical arguments

• LD debaters must develop clear, logical arguments that link the resolution to their chosen value framework
• Arguments should be structured with claims, warrants, and impacts that demonstrate the reasoning behind the debater's position
• Debaters should also consider potential counterarguments and be prepared to defend their case from multiple angles

Anticipating opponent's arguments

• Successful debaters must anticipate their opponent's likely arguments and strategies
• This involves considering the common positions on both sides of the resolution and brainstorming potential responses
• By anticipating the opponent's case, debaters can be better prepared to engage in direct clash and refutation during the debate

Effective LD debating techniques

Clarity and organization of arguments

• LD debaters should strive for clear, well-organized arguments that are easy for the judge to follow
• This involves using signposting language, logical transitions, and clear labels for each argument
• Arguments should be presented in a coherent order that builds a compelling case for the debater's position

Citing evidence and examples

• Debaters should support their arguments with relevant evidence and examples from philosophical texts, real-world cases, and expert opinions
• Evidence helps to bolster the credibility and persuasiveness of arguments
• Debaters should be prepared to explain the significance of their evidence and how it relates to the resolution

Identifying flaws in opponent's logic

• Effective LD debaters must be able to identify and exploit weaknesses in their opponent's arguments
• This may involve pointing out logical fallacies, inconsistencies, or unwarranted assumptions in the opponent's case
• By exposing flaws in the opponent's logic, debaters can undermine the credibility of their arguments and strengthen their own position

Adapting to opponent's arguments

• LD debates require flexibility and the ability to adapt to the opponent's arguments in real-time
• Debaters must listen carefully to their opponent's case and adjust their strategies accordingly
• This may involve prioritizing certain arguments, dropping less important points, or introducing new arguments to counter the opponent's case

Judging criteria for LD debates

Strength and logic of arguments

• Judges evaluate the strength and logical coherence of each debater's arguments
• Arguments should be well-supported by evidence and reasoning, and should clearly link to the debater's value framework
• Judges consider the relevance, specificity, and implications of each argument in relation to the resolution

Refutation of opponent's case

• Judges assess each debater's ability to directly clash with and refute their opponent's arguments
• Effective refutation involves identifying the key points of disagreement, exposing weaknesses in the opponent's logic, and offering compelling counter-arguments
• Debaters who successfully negate their opponent's case while defending their own are more likely to win the debate

Persuasiveness of delivery

• Judges also consider the persuasiveness and clarity of each debater's delivery
• This includes factors such as speaking style, tone, pacing, and the ability to convey arguments with conviction
• Debaters should strive for a confident, engaging delivery that effectively communicates their ideas to the judge

Adherence to LD debate rules

• Judges evaluate each debater's adherence to the rules and norms of LD debate
• This includes following the prescribed speech times, engaging in respectful cross-examination, and avoiding personal attacks or off-topic arguments
• Debaters who consistently violate the rules may face lower scores or even disqualification

Common challenges in LD debates

Managing limited preparation time

• LD debaters often have limited time to prepare their arguments and responses, especially during the debate itself
• Debaters must be able to quickly analyze their opponent's case, prioritize arguments, and formulate effective responses
• Effective time management and the ability to think on one's feet are essential skills for success in LD debate

Defending against strong arguments

• Debaters may face strong, well-supported arguments from their opponents that are difficult to refute
• In these situations, debaters must be able to identify the core of the argument and find creative ways to challenge its assumptions or implications
• This may involve conceding certain points while still maintaining the overall strength of one's own case

Staying within time constraints

• LD speeches have strict time limits, and debaters must be able to convey their arguments and responses within these constraints
• This requires careful planning, efficient delivery, and the ability to prioritize the most important points
• Debaters who consistently run out of time or fail to address key arguments may be at a disadvantage in the eyes of the judge

Differences vs other debate formats

Focus on values vs policies

• Unlike policy debate, which focuses on specific plans and their consequences, LD debate emphasizes philosophical values and principles
• LD resolutions are often more abstract and open-ended, allowing for a wider range of arguments and interpretations
• Debaters must be able to navigate complex moral and ethical questions and apply philosophical concepts to real-world situations

Shorter speech times vs policy debate

• LD speeches are generally shorter than those in policy debate, with a typical LD round lasting around 45 minutes
• The shorter speech times require debaters to be concise and strategic in their argumentation
• LD debaters must be able to quickly get to the heart of the issue and make their case in a clear, compelling manner

Philosophical nature of resolutions

• LD resolutions often deal with deep philosophical questions about justice, morality, and human nature
• Debaters must be well-versed in various philosophical traditions and be able to apply abstract concepts to concrete situations
• The philosophical nature of LD debate requires a different set of skills and knowledge compared to more policy-oriented formats
