Editorial standards

Bottom line up front

Every briefing opens with a BLUF: the answer in one or two sentences. The detail follows.

Confidence

Each briefing states a confidence level and the basis for it:

• High: the core claims rest on primary sources, such as a regulator's own document or a published standard.
• Moderate: the core claims rest on credible secondary reporting, or a mix of primary and secondary sources.
• Low: the claims rest on limited or single-source reporting. We say what would change our view.

Sourcing

We link to primary sources wherever they exist and say so when we rely on secondary reporting. Sources are numbered in each briefing.

Review

Technical primers name a technical reviewer. The reviewer is shown under the headline.

Updates

When facts change we update the briefing, change its updated date and log the change. We do not change dates without changing content.
