Help:Verifiability

Verifiability means that people reading and editing the Dota 2 encylopedia can check that the information comes from a reliable source. Dota 2 Wiki does not publish original research. Its content is determined by previously published information rather than the beliefs or experiences of its editors. Even if you're sure something is true, it must be verifiable before you can add it. When reliable sources disagree, present what the various sources say, give each side its due weight, and maintain a neutral point of view.

What counts as a reliable source
The word "source" in Dota 2 Wiki consists of the following:


 * 1) the type of the content (some examples include heroes, an item, or an event)
 * 2) the creator of the content (for example, a Steam Workshop content creator)
 * 3) the publisher of the content(for example, Valve).

All of the above have an impact on the reliability of the content.

Questionable sources
Questionable sources are those that have a poor reputation for checking the facts, lack meaningful editorial oversight, or have an apparent conflict of interest. Such sources include websites and publications expressing views that are widely considered by other sources to be extremist or promotional, or that rely heavily on unsubstantiated gossip, rumor or personal opinion. Questionable sources should only be used as sources of material on themselves, especially in articles about themselves; see below. They are not suitable sources for contentious claims about others.

Self-published sources
Anyone can create a personal web page or publish their own book, and also claim to be an expert in a certain field. For that reason, self-published media, such as books, patents, newsletters, personal websites, open wikis, personal or group blogs, Internet forum postings, and tweets, are largely not acceptable as sources. Self-published sources may be considered reliable when produced by the creator of the content, whose work has previously been published by a reliable publisher. Exercise caution when using such sources: if the information in question is really worth reporting, someone else will probably have done so.
