Claim: The Assertion

Every argument starts with a claim — the one-sentence assertion you want the judge to believe. You will be able to write a clear, specific claim and distinguish it from vague filler.

What a Claim Is

A claim is a short, declarative statement of what you are arguing, such as 'Raising the minimum wage reduces poverty' or 'Banning the practice increases black-market activity.' A claim by itself is just an opinion — it carries no persuasive weight until it is backed by a warrant.

Specific Beats Vague

Weak claims are broad and unfalsifiable, like 'This policy is bad for society.' Strong claims name a mechanism and a direction, like 'This policy increases youth unemployment by removing entry-level jobs.' Specificity makes a claim easier to prove and easier for the judge to remember.

Worked example

A debater is drafting a contention tag line for a case on plastic bag bans.

Weak claim: 'Plastic bag bans are good.' Strong claim: 'Plastic bag bans reduce marine plastic pollution by eliminating the single largest source of coastal litter.' The strong version tells the judge exactly what mechanism to expect proof for.
