Vague Definition (Unfair Definition)A definition that fails to clearly answer vital questions about what is meant by the motion or what will happen under the policy defended.
Manipulation of Absolute Words (Unfair Definition)An unfair definition that takes words like "all" literally to set an impossible burden or shield from Opposition.
Accept and Debate (Opposition Option)When faced with an unfair or unexpected definition, the Opposition proceeds directly to rebut the Proposition’s case and presents its own.

Mechanism

Chương 1. Argument · Part A: Fundamentals

Mọi thể thức

A mechanism (or Warrant) is a reason provided by the team that is concerned with explaining why or how something will occur. It is purely focused on explaining why a certain outcome will occur and whether that outcome is more likely on one side, rather than focusing on why that outcome is important in the debate.

Example: The ‘inability of casinos to advertise openly and attract crowds’ is a mechanism through which banning gambling reduces the number of people who gamble for the first time, and eventually become addicted.
