Cross-Examination Strategies

Cross-examination (CX) is your chance to take control of the debate. It’s not just a formality - it’s a weapon. If used correctly, it can expose weaknesses in your opponent’s case, force them into contradictions, and set up your own arguments for success. If used poorly, it’s a wasted opportunity.

Most novice debaters treat CX like a conversation. It’s not. It’s strategic. Every question you ask should serve a purpose. Every answer you give should protect your case.

The Purpose of CX

There are three main goals in cross-examination:

  1. Clarify - If something in your opponent’s case is vague or confusing, ask about it. Judges can’t evaluate what they don’t understand. (“Can you clarify how your criterion actually measures justice?”)

  2. Expose Weaknesses - Force your opponent to admit contradictions, lack of evidence, or logical flaws. (“You claim that AGI will lead to mass unemployment, but what about the new jobs created by AI? Do you have data that proves overall job loss?”)

  3. Set Up Your Case - Ask questions that will make your arguments stronger later. If you can get your opponent to agree with a premise that supports your case, you’ve already won half the battle. (“Would you agree that justice requires treating all individuals equally under the law?”)

How to Ask Effective Questions

Not all questions are equal. Some put pressure on your opponent. Others let them escape. Here’s how to ask questions that work:

Weak Question:How do you define justice?”(This gives your opponent too much room to control the discussion.)

Strong Question:So based on your definition, if an innocent person is punished unfairly, that would be unjust, correct?”(This locks them into a logical position that you can use later.)

How to Answer CX Without Losing Ground

When you’re on the receiving end of CX, your job is simple: don’t get trapped. Here’s how:

The Bottom Line

Cross-examination is where you gain control of the round. Ask sharp, direct questions that expose weaknesses and set up your arguments. Answer confidently and refuse to be trapped. If you master CX, you’ll force your opponent onto the defensive before their next speech even begins.
