## Principles

### 01 — Every figure carries a record

No percentage appears anywhere on this site without a reference number that resolves to an entry in the evidence register, giving design, blinding, sample size, duration and endpoint. If we cannot source a figure, we do not print it.

### 02 — Design outranks sample size

A randomised, vehicle-controlled trial of 60 people tells you more than an uncontrolled survey of 18,000. We grade on design first and say so in the grade key.

### 03 — We separate fact from assessment

What a brand publishes is reported as fact and sourced. What we make of it is labelled as assessment. Readers should always be able to tell which is which, and to disagree with the second without disputing the first.

### 04 — We publish what we could not assess

Reviews state their method on the face of the page. Criteria we could not evaluate are left blank and the coverage percentage is printed beside the score.

### 05 — Brands get no advance copy

We will put factual questions to a company before publication and print the answer or the silence. We do not share drafts, scores or embargo dates, and we do not accept conditions in exchange for access.

### 06 — Nothing is unpublished on request

A brand may dispute a fact and we will correct an error. A brand may not have a review taken down, edited into approval, or quietly de-indexed because it is unflattering.
