The method treats research as an iterative loop rather than a one-way accumulation of information. Early interviews often contain decisive evidence, but the researcher lacks enough context to recognize it. After speaking with more people, testing hypotheses, and struggling to explain the narrative clearly, the researcher identifies a sharper critical question. They then return to the earliest notes and transcripts, reading them through this improved lens. Statements that once seemed incidental can become direct answers, reveal contradictions, or supply the organizing idea for the finished work. The output is a clearer narrative grounded in evidence already collected rather than a premature search for still more sources.
Origin
John Authers traced the method to investigative journalist Donald Steel, who told journalism students that many of his scoops came from revisiting old notes. Extracted from Masters in Business.
Core principles
- 01Early evidence gains meaning as context accumulates
- 02Later research reveals better questions
- 03Important answers may already exist in overlooked notes
- 04Re-examination can unlock a stalled narrative
How to run it
- 1
Preserve the Raw Record
Keep complete notes or transcripts from early conversations rather than retaining only conclusions that seemed important at the time.
Pro tip Record surrounding context so later interpretations can be checked against the original exchange.
Watch out Aggressive early summarization may erase the clue you will need later.
- 2
Expand the Context
Continue interviewing, reading, and testing explanations until patterns and unresolved tensions become visible.
Pro tip Track questions that become more precise as your understanding grows.
Watch out Do not assume the first framing of the subject is the correct one.
- 3
Name the Critical Question
State the question that must be answered to unlock the narrative or decision. Make it specific enough that evidence can support or contradict it.
Pro tip If the question cannot change your interpretation, sharpen it further.
- 4
Re-read the Earliest Material
Review the first notes with the critical question in mind. Flag direct answers, overlooked qualifications, and statements whose significance changed with context.
Pro tip Start with the earliest interviews because they were interpreted with the least contextual knowledge.
Watch out Do not silently rewrite ambiguous statements to fit the new theory.
- 5
Rebuild the Narrative
Use the recovered evidence to clarify the explanation, then verify it against the rest of the record.
Pro tip Distinguish what the source actually said from what you now infer.
Watch out A rediscovered quote is evidence, not automatic proof of the entire thesis.
In the wild
An investigative reporter interviews a supplier before understanding a procurement scandal. After twenty more interviews, she realizes that the decisive issue is who approved an unusual contract exception. Re-reading the first transcript reveals that the supplier had already named the approving office, but the detail seemed routine at the time. She verifies the statement with records and reorganizes the article around the approval chain.
→ The reporter resolves the central question without relying on a speculative new source.
An author cannot explain why a company abandoned a successful product. After later interviews reveal an internal incentive conflict, he returns to an early executive transcript and notices a previously overlooked comment about compensation targets. He corroborates it with other material and uses the incentive conflict to structure the chapter.
→ The chapter gains a clear, evidence-based causal narrative.
Common mistakes
Searching Only for New Evidence
Researchers often keep adding interviews when the needed answer is already present in material they collected before understanding the subject.
Re-reading Without a Better Question
Simply reviewing notes again may reproduce the original interpretation. The method works when accumulated context supplies a sharper question or hypothesis.
Forcing Old Quotes Into a New Theory
New context can reveal meaning, but it can also create confirmation bias. Preserve the exact language and seek corroborating evidence.
Is it for you?
Best for
It is best for journalists, analysts, authors, and investigators working through complex, evolving subjects.
Not ideal for
It is not ideal when no original notes exist or when the underlying evidence is unreliable.
From the transcript
“from rereading my old notes”
“when you go back to the first person you talked to, you realize now what the critical question is and that they answered it for…”
“I actually had the answer to them sitting in my notebooks.”
