Editorial policy

Original contribution

Every published guide must add an original synthetic scenario, explanation, calculation, or interactive demonstration. A source summary by itself is not a publishable page. Parameter variations remain within one canonical experiment URL; the site does not create thousands of indexable pages from generated states.

Sources

Definitions and methodological claims should be supported by primary teaching material, standards bodies, official statistical agencies, or peer-reviewed work where appropriate. Sources are checked for the specific claim they support. Links are listed near the article and in the central source index.

Source language is paraphrased. A citation does not imply that the source endorses the site's scenario or interpretation. When reliable sources disagree because they answer different questions, the disagreement and assumptions should be stated rather than flattened into false certainty.

Synthetic-data labeling

Generated examples are labeled synthetic in the experiment, chart caption, and related guide. They must not be described as surveys, tests, observations, benchmarks, or field results. The site avoids realistic personal records and does not generate claims about medical conditions, financial returns, gambling outcomes, political groups, or protected classes.

Automation and human review

Software assists with deterministic calculation, consistency checks, spelling, links, and build validation. Publication still requires a human review gate for mathematical meaning, source fit, unsupported claims, tone, and policy pages. Automated text is not published in bulk and generated output is not treated as evidence.

Advertising and commercial influence

Advertising, if enabled after review, is visually and editorially separate from controls and results. Advertisers cannot purchase favorable examples, placement in calculations, or changes to conclusions. Sponsored statistics, paid rankings, and affiliate product reviews are outside the current editorial scope.

Updates and corrections

Each guide displays its publication and latest update dates. Minor spelling and accessibility fixes may be made without a public note. A correction that changes a number, definition, conclusion, source, or material limitation receives a dated record on the corrections page and, when useful, a note on the affected guide.
