How to write a multi-source summary

Synthesize by claim and evidence role. State the shared fact once, attribute unique reporting, preserve material disagreement, and attach the sources that support each part of the conclusion.[1][2]

Why this gets difficult

A multi-source summary is not improved by averaging every source into one neutral paragraph. That can erase who knows what, flatten disagreement, and give repeated claims more weight than independent evidence.[1][2]

A practical way through

  1. Resolve each item to its original source and identify whether it adds fact, method, context, or interpretation.[1][2]
  2. Cluster items around the same underlying claim before writing.[1][2]
  3. Draft the shared conclusion from independent evidence, not publication count.[1][2]
  4. Keep a source-specific line when a contribution or disagreement changes the takeaway.[1][2]

An example

The situation: Five articles cite one agency report, while a sixth adds original interviews that challenge the expected impact.[1][2]

What changes: The agency report anchors the common fact, its five rewrites count once, and the interview reporting remains a distinct perspective.[1][2]

What you get: The summary reflects evidence diversity rather than mistaking repetition for corroboration.[1][2]

What to watch for

  • Sources may share an undisclosed origin, making apparently independent agreement less meaningful.[1][2]
  • Compression can remove qualifiers; high-stakes claims still require reopening the primary material.[1][2]

Sources worth keeping

  • Primary documents or original reporting for the common fact.[1][2]
  • Sources with genuinely independent evidence.[1][2]
  • Specialists whose disagreement is tied to a method or assumption.[1][2]

How Scottie helps

Scottie groups source items into stories before writing and keeps viewpoints separate when their differences matter to the reader.[3]
