Submit Evidence for Validation Consideration
Market Proof Lab's evidence record is built from publicly available sources, and no research process captures every relevant piece of public evidence. If you have identified publicly available evidence not reflected in a Lab validation output, this pathway is the formal channel for submitting it for review. All submitted evidence is assessed against the same seven-class proof framework applied to all Lab research.
What this pathway is for
The evidence submission pathway exists because any structured research process can miss publicly available evidence. Market Proof Lab's coverage of a category or vendor is based on the evidence the research team was able to identify from public sources at the time of publication. New public evidence may become available after publication. Evidence that existed at publication time may not have been identified. Either situation can affect a proof classification.
This pathway accepts publicly available evidence for review. It is not a channel for requesting favorable coverage, disputing editorial interpretations without new evidence, or advocating for a different proof classification without supporting it with public sources. The proof record is updated when the evidence record changes — not when a vendor prefers a different classification.
Evidence we can review
- Publicly accessible regulatory filings or compliance records
- Published third-party research or analysis from independent sources
- Public court records or documented legal proceedings
- Published industry certifications verifiable through the issuing body
- Documented practitioner or community discussions in public forums
- Published news coverage from editorially independent sources
- Publicly accessible product documentation or technical records
- Search and market signal data from public measurement tools
What this pathway cannot accept
- Confidential or proprietary materials not publicly accessible
- Internal documents not available to independent researchers
- Requests for favorable coverage or improved proof classification without evidence
- Objections to editorial interpretations unaccompanied by new public evidence
- Materials that require the Lab to verify their authenticity without independent corroboration
- Anonymous submissions without at minimum a contact email for follow-up
How evidence is assessed
All submitted evidence is reviewed against the Lab's seven-class proof framework. The class assigned to submitted evidence determines what proof weight it carries and whether it changes a proof classification. Evidence submitted by vendors or parties with a relationship to the subject is classified as Class 6 (submitted evidence) regardless of the quality of the material — this is not a judgment on the material's accuracy, but an accurate statement of its independence status.
Submission process
Identify the specific output and claim
Identify the specific Market Proof Lab validation output and the specific proof classification or documented claim you believe is incomplete or incorrect based on publicly available evidence. The more precisely the submission identifies the specific claim, the more directly the review can be targeted. General submissions without a specific claim reference take longer to assess.
Confirm the evidence is publicly accessible
Before submitting, confirm that the evidence you are providing is publicly accessible — available to any researcher from public sources without requiring vendor cooperation, confidential access, or materials not already in the public domain. Evidence that cannot be independently verified from public sources cannot change a proof classification, because the Lab cannot independently verify it.
Submit via email with complete source information
Send your submission to [email protected] with the subject line "Evidence submission: [category or output name]." Include the specific URL or document reference for each piece of evidence, the specific claim it addresses, and your assessment of how it relates to the current proof classification. The research team will review the submission and respond within 10 business days.
Evidence review and classification
The research team assesses submitted evidence against the seven-class proof framework. Evidence is classified by class and assessed for its proof weight relative to the specific claim it addresses. The team determines whether the submitted evidence changes the existing proof classification, adds supporting or contradicting context to the record, or does not meet the threshold for inclusion in the evidence record.
Accepted corrections update the proof record
If submitted evidence is accepted and changes a proof classification or adds materially to the evidence record, the relevant validation output is updated and a changelog entry is created documenting the date, what changed, the evidence class of the submitted material, and the new proof classification. Submitters are notified of the outcome. The correction is documented in the Lab's public changelog at marketprooflab.com/changelog/.
Who can submit
The evidence submission pathway is open to all organizations and individuals, including vendors whose claims are assessed in Lab research, research organizations, journalists, practitioners, and members of the public. The identity and relationship of the submitter are not factors in whether submitted evidence is accepted — the evidence class and proof weight of the submitted material are the determining factors.
Evidence submitted by vendors or parties with a disclosed relationship to the subject is classified as Class 6 (submitted evidence), regardless of the quality of the material. This classification accurately reflects the independence status of the source. Class 6 evidence can be included in the evidence record as supporting context but does not substitute for Class 1-5 independent evidence in proof classification decisions.
