Research provenance is the documented chain of custody that connects every claim in a research deliverable to the source it came from: who said it or where it was published, how the source was verified, when it was gathered, and where the record is held. A provenance appendix is the section of a report that presents this chain so the client can inspect it.
A term borrowed from art and archives
Provenance is the word museums use for the documented history of an object: who owned it, when, and how it changed hands. A painting with a gap in its provenance is worth less, because the gap is where forgery and theft hide. Research is now in the same position. A claim without a documented source is where hallucination and fraud hide.
What a provenance appendix contains
| For each interview | For each document |
|---|---|
| Role and organisation type (name where consent permits) | Full citation with a working link or reference |
| How identity and role were verified | Who opened and checked the source, and when |
| Date and duration of the conversation | The specific passage or figure relied on |
| Where the recording or notes are stored | Any known limitations of the source |
| Consent status for follow-up |
Why it is the new minimum
Until recently a client could assume that a report from a reputable firm rested on real sources. That assumption failed publicly in 2025 and 2026. Deloitte Australia refunded part of a A$440,000 fee after a report cited a court judgment that did not exist. PwC Middle East published reports whose footnotes pointed nowhere. In neither case was the problem that AI was used. The problem was that no human had opened the sources, and the client had no way to check. A provenance appendix makes that check possible before the report is relied on rather than after it has failed.
What provenance does not do
It does not make the sources right. A verified expert can be wrong. Provenance tells you who said what and lets you weigh it. Judgment about what the evidence means is a separate act, and it should also have a name attached. That is why Theory pairs every provenance appendix with a signed recommendation.
How to ask for it
Add one line to any research or consulting brief: "The deliverable will include a provenance appendix listing every source, its verification method and date." A supplier who can do this will say yes immediately. A supplier who cannot will explain why it is not necessary. That explanation is the answer.
