Presentation: Lincoln-Douglas Debate

Adapted from handout by Robert Marmorstein

For your presentation grade in this class, I want you to participate in a Lincoln-Douglas Style Debate.

In a Lincoln-Douglas debate, the opponents alternate speeches. The affirmative speaker speaks three times. The negative speaker speaks twice. The general structure is this:

Speeches

First affirmative constructive speech (1AC): 6 minutes – The affirmative speaker lays out their case for the proposal.

Cross-Examination: 2 minutes – The negative speaker asks questions about the case.

First negative constructive speech (1NC): 7 minutes – The negative speaker argues against the points made in the first affirmative constructive and describes possible disadvantages of the plan.

Cross-Examination: 2 minutes – The affirmative speaker asks questions about their opponent's arguments.

First Affirmative Rebuttal (1AR): 4 minutes The affirmative speaker responds (very quickly) to all of the negative speaker's points.

First Negative Rebuttal (1NR): 6 minutes The negative speaker replies to the points made in the 1AR.

Second Affirmative Rebuttal (2AR): 3 minutes The affirmative speaker (very, very quickly) summarizes their points and tells why they should win.

Preparation Time

In between speeches, the speakers can use “prep time” to look through their evidence and decide what to say. Each speaker gets a total of 2 minutes of preparation time to use through the debate.

Summary:

Each person gets 13 minutes to talk, plus 2 minutes of cross-examination, plus 2 minutes to prep. That's 17 minutes each or 34 minutes total.

(This is trimmed slightly from the standard L-D debate format in order to be able to fit two debates in a class period.)

Constructive Speeches

In the constructive speeches, you make your case.

Example: The State of Virginia Should Significantly Change Its Speed-Limit Laws (See attached sheet)

The structure of the 1AC:

1. Statement of the topic

2. Harms – What “bad” things are happening because we haven't adopted the policy? – Usually qualitative

3. Significance – Why do these things matter? (Financial cost, environmental cost, health cost, etc.) – Usually quantitative

4. Inherency – We can't fix the “bad things” without the plan. – For instance: There is some sort of legal barrier. There is some sort of prevailing attitude that prevents a solution. No one has done this yet.

5. Plan -- Mandates – What steps can we take to solve the problem? – Should be fairly specific. -- Funding – How will we fund the proposal? -- Administration – Who will implement the proposal?

6. Solvency – The plan will solve the problems outlined in the “harms”. – Use of empirical examples is good (it's worked somewhere else).

7. Closing Statement -- Something like "vote for me".

The structure of the 1NC:

The first negative constructive should follow the same order as the affirmative constructive. You want to attack pretty much everything they said, if you can. The best way to do this is to cite a source that contradicts it, but you can also just use common sense, logic, or other argumentation.

The general pattern is to do something like, "They said X, but really Y."

To attack their plan, you want to present some disadvantages. You should prepare these arguments in advance. Each “disadvantage” should be presented in three parts:

Link – Their plan causes the disadvantage.

Uniqueness – Nothing else causes it.

Impact – It's bad.

For example,

Disadvantage 1: Raising speed limits leads to worse accidents

A. Link: Raising speed limits increases the severity of accidents

Katy Waldman, "I Can't Drive 85: Do Higher Speed limits cause more car accidents?", Slate.com, June 12, 2012

“Do higher speed limits cause more car accidents? No, but they do cause more severe ones. Accidents that occur at high speeds are more often fatal, since high-velocity objects collide with greater force. Overwhelmingly, studies show that freeway deaths increase with freeway speed limits, although it’s hard to know how much of that upturn stems from the greater volume of overall traffic that’s drawn in by looser speed regulations.”

B. Uniqueness: Since speed limits are directly related to more severe accidents, other changes don't affect whether the speed limit is safe.

C. Impact: High speed causes fatalities

“There were 274 traffic deaths in NYC in 2012, compared to 245 in 2011. Motor vehicle occupant fatalities increased from 50 to 73. The number of pedestrian and cyclist deaths was mostly unchanged: 166 in 2012 compared to 163 in 2011. Pedestrian fatalities were up in 2012, while cyclist deaths decreased.

Speeding was the leading single factor in traffic deaths, contributing to 81 fatal crashes.”

Disadvantage 2: Raising the speed limit reduces fuel economy

A. Link: Cars are designed to run at 55 MPH

“Speed Kills MPG”, MPGForSpeed.com, May 13, 2008

“Unfortunately, it's true. Your car's gas mileage decreases once it gets past its optimal speed. For most cars, this is around 55-60 mph. This means that every time you go over this speed, you're essentially wasting gas and money - and creating unnecessary greenhouse gases. “

B. Uniqueness: Other factors that affect MPG are unlikely to change – Weight of the car – Volume of the car – Make and Model of the car

– Driving behavior like jack rabbit starts

C. Impact: Greenhouse gases cause global warming and kill us all Spencer Weart, “The discovery of global warming”, American Institute of Physics, February 2015

“A few scientists took a closer look in the late 1950s when they realized that the level of carbon dioxide gas (CO2) in the atmosphere might be rising, suggesting that the average global temperature might climb a few degrees Celsius before the end of the 21st century. Roger Revelle, the most senior of these researchers, publicly speculated that in the 21st century the greenhouse effect might exert "a violent effect on the earth's climate" (as Time magazine put it). He thought the temperature rise might eventually melt the Greenland and Antarctic icecaps, raising sea level enough to flood coastlines. Noting that climate had changed abruptly in the past, perhaps bringing the downfall of entire civilizations in the ancient world, in 1957 Revelle told a Congressional committee that the greenhouse effect might someday turn Southern California and Texas into "real deserts."

Cross Examination:

What is cross-examination for?

1. To clarify things you missed or didn't understand.

2. To try to "trip up" your opponent by getting them to contradict themselves.

3. To "set up" one of your arguments in the next speech.

Rebuttals:

Rebuttals are your chance to attack your opponent's arguments.

Rule: The affirmative MUST win at least one point of every issue to win. The negative MUST win all points of at least one issue to win.

Flowing:

It is very important to take good notes during the debate. To do this properly, turn your notebook sideways. Divide each page into 5 columns, one for each speech. Take notes about the speeches vertically, leaving space so you can match points in the 1AC to points in the 1NC to points in the 1AR to points in the 1NR to points in the 2AR.

Tips for good public speaking:

1. Make eye contact with each person in the audience at least once. Don't spend time looking at your opponent (even during the cross-examination): your audience is the audience.

2. Instead of saying uh or um, pause and collect your thoughts.

3. Pay attention to volume. Be sure you are loud enough we can hear you.

4. Preparation makes the best speech. Do your research and have your briefs ready. If you are negative, this is especially important!

5. Use appropriate gestures. Don't pace back and forth. Try to keep your hands still unless you need them to make a point.

6. Make sure you use your time effectively. If you are giving a 1AC, read through your speech a couple times to see how long it takes. Make sure you can get through the whole thing in 6 minutes!

7. Use formal language. Be polite to your opponent.
