Verifiability is one of Wikipedia's core rules that stems from the principle of point of view neutrality. Along with the ban on posting unpublished work, the rules determine what may or may not be published on Wikipedia. They must be interpreted in relation to each other, and it is recommended that Wikipedia contributors know them well and make them their own. Information can only be mentioned if readers can verify it, for example if it has already been published by a quality source or reference. Contributors must provide such a source for all disputed or potentially disputed information. Otherwise, they can be withdrawn. Verifiability is not truth: our personal opinions about whether information is true or false are irrelevant in Wikipedia. What is essential is that all potentially disputed information, as well as all theories, opinions, claims or arguments, be attributed to an identifiable and verifiable source. It is particularly important to ensure the verifiability of extraordinary or controversial information, with sources of a quality proportional to their extraordinary or controversial degree.


One of the major criticisms against Wikipedia is the absence of a validation process, with critics deducing that the information is unreliable if there is no way to ensure the competence and possibly the honesty of the editors. Indeed, for those who wish, the anonymity of contributions is relatively well guaranteed by Wikipedia and anyone can claim expertise without ever having to prove it. Ultimately, Wikipedia does not offer any tool to assess the validity of the assertions made in an article, and it is extremely unlikely that this situation will change in the future, as this would require the questioning of several of the founding principles. . The only means at our disposal to offer useful content is therefore to rely on institutions that are equipped to verify the validity of these and therefore to refer the reader to publications that have recognized them as valid. What reliable sources should I use? Reliable sources Wikipedia articles must be based on reliable and independent sources to allow verification of facts and the accuracy of the information presented. These sources must have a direct relationship with the information present in the article. The relevance of the sources depends on the author, the publisher, the context and the link between the assertions and the source. The best sources are published by structures or people with the means to verify, analyze and cross-check facts, arguments and evidence. University and academic publications are generally the most reliable sources, especially in science or medicine, but also in fields such as history and philosophy. It is also possible to use reliable sources that are not academic, depending on the disciplines. The main reliable sources are: academic publications and textbooks; books published by respected publishers; mainstream newspapers. Unreliable or unreliable sources Publishers, especially press publishers, who publish reliable sources may also publish more questionable content. While some news outlets publish content with professional expertise that can be considered trusted sources, those same publishers may publish content that is not considered trusted sources such as certain blogs, op-eds, or editorials.
