Introduction to Disadvantages

What is a Disadvantage?

Commonly abbreviated as a disad or a DA, a disadvantage is an argument on the negative side of the debate that seeks to either prove the affirmative side as ineffective or a net harm. 

Similar to the other parts of a case, a disad has the same structure! As a reminder, that structure is: 

• Uniqueness (UQ): The uniqueness is an analysis of the current world, describing and painting a picture of what is actively happening right now in reference to the resolution. 

• Link (L): The link links the uniqueness to the impact, for example, by explaining how something will get better, get worse, not change, etc. 

• Internal Link (I/L): Though often invisible, implied, or chalked up to common knowledge, the internal link is a link between the link and the impact.

• Impact (IMP): The impact is why your argument actually matters, or what will happen as a result of affirmation or negation. For example, common impacts include climate change getting worse/better, the economy imploding/booming, war will break out/war will cease, etc.

Since this is a negative argument, disads will typically focus on a net negative that the policy/resolution produces OR how doing the policy/resolution will stifle the ability to do something else that may solve the issues in the round better than the affirmative describes.

How does a disadvantage function?

In every debate round, the affirmative and negative debater are each given a burden: 

• The affirmative debater has what is called the “Burden of Proof.” Essentially, for the affirmative debater to win a round, they must prove that their argument is advantageous to some standard, usually revolving around their framework. 

• On the other hand, the negative debater has what is called the “Burden of Rejoinder.” In general, for the negative to win the round, they must prove that either A. The affirmative is disadvantageous to some standard or B. The affirmative makes other methods that solve better impossible/it’s better to do something else instead that the affirmative’s policy action prohibits. 

What should my goal be when I read a DA?

As explained above, the purpose of a DA is to say that the affirmative makes some undesirable consequence, either something that is “bad” or stops us from doing something that is “better” than what the affirmative proposes. These types of arguments that explain why the negative position should win the debate are referred to as “offensive arguments.” 

However, sometimes arguments don’t necessarily need to be about why you win, but rather why you shouldn’t lose. This type of argument is called a “defensive argument.”

Although they sound similar, these 2 ideas carry profound differences for debate. Let’s take an example:

Let’s say I am the negative on the January/February 2026 LD topic, which states, “Resolved: The possession of nuclear weapons is immoral.” Since I am the negative, I’ll argue that the possession of nuclear weapons is not an immoral action or at least that not possessing them would produce comparably more immoral actions. 

We’ll call my sample disadvantages DA 1 and DA 2: 

DA 1: Bioweapons

• States that if states did not have nukes, then they would seek to create biological weapons, or for short, bioweapons. These are weapons that use viruses, pandemics, and other forms of disease to wage war on others, similar to that of the Mongol Empire. 

• This illustrates part B of the “Burden of Rejoinder.” The affirmative’s idea of getting rid of nuclear weapons is bad because it promotes states to make bioweapons- countries wouldn’t just stop war if they didn’t have nukes, they’d find new, potentially worse, ways to keep up. 

DA 2: Asteroids 

• If states did not have nukes, then if a large asteroid were to collide with Earth, we’d have no way to stop it. These large asteroids carry the potential to end all of Earth, and the only current means we have of stopping such a threat is with nuclear weapons. 

• This illustrates part A of the “Burden of Rejoinder.” The affirmative’s idea is inherently bad because it produces an undesirable consequence: the threat of extinction via an asteroid. 

Ok, that was a lot of words and a lot of explanations. Let’s take a step back and have our friend Disad Dan help us out with the rest :) 

Dan is bored. Like any logical person, Dan goes and stands on the edge of a cliff to look off into the sunset. Sounds great right? Let’s examine the different parts of Dan’s decision using the ideas we’ve learned above!

First, let’s go with the affirmative:

• Uniqueness: Currently, Dan is bored :(

• Link: In order to stop being bored, Dan decides to go watch the sunset at the edge of a cliff :)

• Internal Link: Generally, when people see sunsets they become less bored and more engaged.

• Impact: Overall, this leads to more happiness and fulfillment for Dan, which we can say is advantageous to what the status quo (uniqueness) was before. 

This all sounds great, but unfortunately, it wasn’t for Dan. Suddenly, a strong gust of wind comes and Dan loses his balance and plummets to his death. How would the negative articulate this argument as a DA? 

DA: Dan’s Death :(

• Uniqueness: Dan was standing at the edge of a cliff.

• Link: A strong gust of wind came and toppled Dan over the cliff.

• Internal Link: Because of gravity, Dan fell off the cliff at a force equal to his mass * acceleration. 

• Impact: This force was too much for Dan to handle, so when he hit the ground, he died :(

Obviously, the affirmative didn’t plan for Dan to die. Had we stopped just with the affirmative case, then we wouldn’t have seen the unintended, and obviously, undesirable consequences of Dan dying.
