Editorial and sponsorship policy

A document tool is worth exactly as much as its independence. This page explains how it is decided what enters the corpus, who pays for this, and precisely what a sponsor cannot buy.

1. The editorial line, in three sentences

2. What goes into the corpus

The full criteria — sources, thematic axes, relevance filters, indexing and known limitations — are in Method and limitations, and the exact composition is in The corpus. In short: peer reviewed scientific literature, DOI-registered output from any discipline, relevant grey literature — reports, proceedings, theses — and our own archive. Open access is preferred, and from closed works only metadata, abstract and link are kept.

A document being in the corpus does not mean we endorse what it says. An honest corpus contains studies that contradict each other: that is why every answer states the level of evidence behind what it cites.

3. Who pays for this

Noosphere is sustained by subscriptions, donations and, where applicable, identified sponsorships. There is no programmatic advertising, no ad networks and no sale of data. The list of sponsors, once there is one, will be public.

4. What a sponsor cannot buy

Not by paying, not by negotiating, not by accident. It is written into the contract they sign:

What they do buy is visibility, clearly labelled, around the edges of the tool: the welcome screen, the footer, the documentation pages and the sponsors page.

5. How it is labelled

Every paid placement carries the words "Sponsored" or "With the support of", visibly and without euphemism, and its links carry the rel="sponsored" attribute. If you have to wonder whether something is advertising, we have done it badly: tell us.

6. Advertisers we do not accept

7. Errors and corrections

If an answer misquotes, attributes something to the wrong person, or leans on a retracted paper, we want to know: noosphere@psiconautica.org. Retracted or refuted documents are flagged or removed from the corpus, and any systematic failure we find is documented in Method and limitations, not buried.

8. Conflicts of interest

Noosphere is part of psiconautica.org and shares its editorial direction. Part of the corpus's own archive comes from publications linked to the project — among them the back catalogue of Cannabis Magazine — and that is declared on the corpus page. Any other material economic relationship with an organisation cited here would be declared on this same page.
