How evidence is assessed

Testimony is evidence. Verification is a process.

A workplace experience does not become meaningless because it was never written down. At the same time, the project must avoid treating every account as automatically proven.

Evidence categories

Different forms, assessed in context.

First-hand account

A contributor describes an event, conversation, decision or workplace experience they directly experienced.

Direct witness account

A contributor describes something they personally observed involving another employee.

Contemporary record

A note, message, email, calendar entry or other record created close to the event.

Supporting document

Material that supports part of an account, even if it does not establish every detail.

Independent corroboration

Another contributor independently reports materially similar information.

Pattern evidence

Multiple independent accounts reveal a recurring theme across locations, roles or time periods.

Public-source evidence

Official publications, company statements, reputable journalism, legal records or archived websites.

Company response

Information provided by MECCA or another relevant party in response to a claim or theme.

Status labels

Precise language matters.

First-hand testimony

Direct personal experience.

Directly witnessed

The contributor personally observed the event.

Supported by records

Records support part of the account.

Independently corroborated

A separate source supports a material element.

Pattern identified

Similar information has been independently received across multiple accounts.

Partially corroborated

Some significant details are supported while others remain unconfirmed.

Disputed

A relevant party has provided conflicting information.

Unverified

There is not enough information to support the claim.

Unable to determine

The evidence does not allow a responsible conclusion.

Verified factual element

A specific detail is supported through reliable documentation, independent sources or both.

Never describe an entire person as verified. Verification labels apply only to specific claims or factual elements.

Assessment process

From receipt to publication decision.

01

Receive

The contributor shares an account and chooses how they may be contacted.

02

Record consent

Research, follow-up, interview and publication are separate decisions.

03

Establish direct knowledge

Identify whether the person experienced, witnessed or heard about the event.

04

Clarify context

Record broad dates, location, role, period and circumstances.

05

Identify themes

Code the account by relevant areas of inquiry.

06

Review supporting information

Review relevant records where available.

07

Compare independent accounts

Assess similar experiences across locations, roles and periods.

08

Examine contradictions

Document conflicting information and alternative explanations.

09

Seek response

Offer relevant parties a fair opportunity to respond.

10

Make a publication decision

Publish only where consent, public interest, safety, fairness and standards support it.

Pattern thresholds

When does a theme become a pattern?

The project does not rely on a rigid number. It considers independence, geographic spread, roles, seniority, periods, similarity, records, witnesses, contradictions and alternative explanations.

Ten vague accounts may be less persuasive than three detailed, independent accounts supported by records.

Limitations

Limits of testimony-based research

Memory, interpretation, incomplete information and time can affect testimony. Contributors are self-selecting, so their experiences cannot be treated as representative of the entire workforce.

Where the available evidence is insufficient, the project will say so.
