When to use it

  • You are about to cite a source and have only read it for agreement.
  • A seminar or tutorial is coming and you need the source's weak joints named.
  • Two sources conflict and you need more than vibes to choose.

What to ask AI

Type something like: “Here's a source I'm thinking of relying on [paste]. Cross-examine it: claims, evidence, interests.”

Ask what is missing, not only what is said.

Decide whether you still rely on it, yourself.

How it helps

Agreeable sources feel trustworthy because they fit what you hoped to find.

Cross-examination puts the source in the witness box before you cite it.

You ask what exactly is claimed, what evidence is present, what is missing, and who benefits if you believe it.

Sometimes you keep the source. Sometimes you downgrade it. Both outcomes are wins.

How to run it

  1. Paste a manageable excerpt (or a clear summary plus key quotes).
  2. List the exact claims before evaluating them.
  3. Ask what evidence is actually offered versus gestured at.
  4. Ask about interests, audience, and omissions.
  5. Write a one-line reliability judgment and whether you will cite it, and for what.

Example exchange

You

This blog says “the new study proves screens destroy teen sleep.” I want to cross-examine it before I cite it.

AI

What exact claim in that sentence is measurable, and does the piece report sample, design, or effect size, or only a headline?

You

It cites one correlational survey, no effect size, and the site sells sleep apps. I’ll cite the survey cautiously or find the paper.

AI

Write one line: what will this source be allowed to support in your essay?

Copyable prompt

Here's a source I'm thinking of relying on [paste]. Cross-examine it:
what exactly is it claiming, what evidence is actually present, what is missing,
and what interests or audience shape it? Do not tell me to trust or ditch it
until I give my judgment.

The Tell

If you have never abandoned or downgraded a source after cross-examining it, you may be confirming, not examining.

If the AI issues a trust verdict before you judge, take the verdict back and decide yourself.

Principle evidence

Strength of the underlying learning idea, not a claim about AI products.

The underlying learning idea is rated moderate. Source interrogation is central to information literacy and historical sourcing: authorship, evidence, audience, and omission matter for trust.

AI delivery evidence

Whether an AI tutor delivers this method well is a separate question.

AI can misread sources or invent bibliographic details. Verify quotes and citations. Delivery is speculative.
