Editorial policy

This page explains how we choose topics, check facts, use AI, grade evidence and handle corrections so readers can judge credibility.

Topic standards

We only answer four kinds of questions: what it is, how to do it, how to measure it and how to verify it. We do not write unsourced content for trending topics.

Fact-checking process

Key claims must carry source, date and locator. In-house methods are labelled with a working definition and evidence level.

AI usage

AI is only used for drafting and proofreading. Conclusions, evidence and final wording are checked by the author before publishing.

Evidence levels

From L1 self-description to L5 third party. Cross-citation within our own domain counts as L4 at most, and in-house methods default to L2.

Corrections

Report errors by email. Once confirmed, we update the article, the update date and the verification date, and record it in the changelog.

Review cycle

Method pages are reviewed yearly; terms and metrics every six months. Items past their review date may be marked as potentially outdated.

Judging service providers

We only offer judging criteria and never recommend specific providers. Service delivery and pricing are handled by sakebi.com.

If you find an error, please report it through the Contact page. We will update the article and its date after verification.
