Multi-Source Reasoning

Retrieve only the relevant facts across tabs or sources without trying to memorize the entire information set.

4 min

Mindset

Multi-Source Reasoning rewards targeted retrieval.

You do not need to learn every tab. You need to find the source that contains the fact required by the current question.

Framework

Use this retrieval sequence.

  • Read the question first.
  • Identify the key noun, metric, or claim.
  • Predict which source is most likely to contain it.
  • Open that source and scan for the target.
  • Check another source only if the answer depends on it.

Definition trap

Similar terms can have different definitions across sources.

A label such as "revenue" may mean gross revenue in one tab and net revenue in another. Use the definition attached to the specific source.

Efficiency

Do not open every tab before you know the question.

That creates memory load and makes similar facts harder to distinguish.

Mental map

Build a tiny mental index instead of a full summary.

For example: Tab 1 = policy, Tab 2 = monthly data, Tab 3 = customer comments. Then retrieve details when needed.

Cross-source claims

When a claim combines sources, verify each part at its source.

Do not let a true fact from one tab make an unsupported second fact feel true.

Mini application

Try this: a question asks whether a policy threshold was met in March.

Which source should you inspect first: policy text, monthly data, or customer comments?

Solution

Start with the policy text to identify the threshold, then check March in the monthly data.

The task requires a definition from one source and a measured value from another.

Remember this

Retrieve; do not memorize.

Question first, likely source second, targeted scan third.
