Controversiality

• The proposition should state a thesis that is potentially disputable rather than one about which most people would agree

• The proposition should be clearly and precisely stated; ambiguous terms and double-barreled claims should be avoided

• The claim should be stated in objective, neutral language rather than in a way that reveals the personal biases or prejudices of the person making the claim.

• The proposition should confront an audience's prevailing beliefs, values, or state of affairs.
