Editorial Principles

What follows explains how Jouer à Deux chooses its topics, checks its facts against their sources and fixes its mistakes.

Editorial Independence

No content is sponsored, commissioned or reviewed by a brand before publication. Outside links earn no commission: they lead to sources, or to useful resources. No fake reviews, no invented testimonials. No fake authors: the byline is the editorial team's.

The Hierarchy of Sources

Sources are chosen in this order:

1. federations, government bodies and institutes, official texts;
2. published studies and independent tests;
3. recognized news media, national or specialized;
4. a manufacturer's spec sheet, for its own product only.

No shops, no marketplaces, no price comparison sites.

Today, the site's sources include: 9 sources from official bodies or institutions, 2 scientific publications, 10 press titles.

How Each Fact Is Checked

Every piece of data — figure, rule, trend — is tied to a source that anyone can access, with a date. If no source establishes it, it isn't published.

Before publication, each fact is matched against the text of its source. It's removed if its source doesn't confirm it, if the source has disappeared or if it's a shop.

Last check of all the facts: October 13, 2026.

Each article names its sources, with their type and the date they were checked.

How Topics Are Chosen

Each article starts from a practical question on the site's theme (doubles strategy in pickleball). These are the questions that come up most often in readers' searches. The answers rely on material from recognized sources, which each article cites. No topic is requested or paid for by a brand.

Correction Policy

When a source is updated or a mistake is spotted, the point in question is corrected, or removed if nothing supports it anymore, and then every page that uses it is redone; the update date follows. No page is redated without a real change; no date is ever moved back.

This site has no form and no contact address: the publisher doesn't disclose their identity, and nothing is collected about readers. Every correction therefore starts from the sources. Content that looks illegal should be reported to the host, as the legal notice explains.
