Evidence Matrix & Source Indexing
When research contains many documents and competing claims, an evidence matrix can connect the question to the exact source instead of relying on memory.
Define the question or claim
Create rows around the questions, events or assertions the research needs to evaluate.
Identify the supporting item
Record the document, record, webpage, interview or other source tied to the issue.
Preserve chronology
Track source and event dates separately when timing affects interpretation.
Capture the relevant point
Summarize what the source contributes without rewriting the entire document.
Show contradictory material
Record where sources disagree rather than hiding the inconsistency in narrative notes.
Make retrieval immediate
Keep a stable link, file path, document ID or other locator that leads back to the underlying source.
A matrix turns research into a reviewable system.
The format is especially useful when many sources touch the same issue, when chronology matters, or when different readers need to verify where a summary came from.
