What the 1st Prop does

The first proposition speech in World Schools Debate is eight minutes. You are the first speaker the panel hears, you set the definition the round will run on, you build the substantive case, and you hand it off to your 2nd speaker who extends.

The job has four parts: define the motion clearly, state the burden of proof both sides should meet, present 2-3 substantive arguments, and end with one line that sets up the rest of the prop case for the 2nd speaker. In that order.

WSDC panels are mixed: some are pure-flow adjudicators, some weight rhetoric and adaptation more heavily. The 1st Prop speech is where you signal you understand the format. Sloppy here and you spend the rest of the round digging out.

Definition: be reasonable

WSDC definitions are looser than Asian Parli definitions. You do not need a statutory mechanism with named actors. You need a reasonable interpretation that gives the opposition genuine ground to attack and the proposition genuine ground to defend.

Squirrels (unreasonably narrow definitions) lose on principle in WSDC. Panels will rule against a proposition that defined the motion in a way no reasonable opposition could attack. So define generously: state what the motion would mean in plain reading, name the most contested interpretation, and move on.

Example, motion = "This house believes that social media has done more harm than good." Definition: "We interpret social media as the major platforms (Facebook, Instagram, TikTok, X, YouTube) and the 2010-present period. The harm-vs-good question is comparative: net welfare assessment across the population using these platforms." 20 seconds. Both sides have clear ground.

Burden of proof

After the definition, state the burden: what does each side need to prove to win. This is more formal in WSDC than in APDA. Adjudicators expect it.

On comparative motions ("does more harm than good"), state that both sides need to show net effect, with examples representative of the affected population. On policy motions ("this house would..."), state that proposition shows the policy is preferable to the status quo on key axes.

Stating the burden does two things. It commits the opposition to the same standard. And it signals to the panel that you understand the structure of the round, which builds early credibility.

Build 2-3 substantive arguments

After definition and burden (about 90 seconds combined), you have 6.5 minutes for substantive content. Build 2-3 arguments. Not 5.

Each argument should have: a clear claim, two or three warrants (mechanism + evidence), an impact, and a brief comparative note about why this argument matters more than the obvious opposition response.

Order the arguments by strength: lead with your most defensible argument (because the judge's attention is highest in the first 3 minutes), put your second-strongest second, and if you have a third, make it short.

In a motion about social media harm: argument 1 = mental health (strongest, most-cited evidence, biggest magnitude). Argument 2 = political polarization (substantive, well-warranted, harder to attack on warrant). Argument 3 (short) = attention economy externalities. Three arguments in 6 minutes, each gets 2 minutes, all develop.

Pre-empt the obvious opposition attack

The strongest 1st Prop speeches pre-empt the obvious opp move. You know opp's 1st speaker will argue that social media also has connective benefits. Address it in your final argument: "Opp will argue connective benefits. We grant connective benefits exist. The burden, as we stated, is comparative net welfare. Three responses on why net welfare still favors prop..."

You have not won the connective-benefits fight. But you have planted a frame, and now opp 1 has to clear two arguments instead of one to make their lead stick.

Do not pre-empt every possible opp move. Pick the one you know they will lead with. One pre-empt is strategic; five is paranoid and eats your time.

Hand off to your 2nd Prop

End the speech with 20 seconds reserved for partner handoff. "2nd prop will extend on the mental-health argument with the new platform-specific data, respond to whatever opp 1 brings on the political-polarization piece, and add the third argument I previewed."

This does two things. It tells the panel there is a coherent two-speech strategy on prop, not just two solo speeches stapled together. And it gives your 2nd Prop explicit licensed turf so they do not retread your ground.

WSDC panels reward bench coordination. If 1st and 2nd Prop sound like they prepped together, the prop case feels more substantial than the opp case even when the content is similar.

Sample lines

Definition for a social-media motion.
"We interpret social media as the major platforms (Facebook, Instagram, TikTok, X, YouTube) over the 2010-present period. The harm-vs-good question is comparative: net welfare assessment across the population using these platforms."
Concrete platform list, time-bounded, frames the burden as comparative. Opp gets attackable ground; prop gets defendable ground. No squirrel.
Partner handoff line.
"2nd prop will extend on the mental-health argument with the new platform-specific data, respond to whatever opp 1 brings on political polarization, and add the third argument I previewed."
Tells the panel there is a coherent two-speech strategy. Licenses turf for 2nd prop. Saves the bench from a panicked huddle between speeches.
