The threshold for inclusion in Wikipedia is verifiability, not truth. This policy and the verifiability policy reinforce each other by requiring that only assertions, theories, opinions, and arguments that have already been published in a reliable source may be used in Wikipedia.

Neutral point of view
Main article: Wikipedia:Neutral point of view
The prohibition against original research limits the extent to which editors may present their own points of view in articles. By reinforcing the importance of including verifiable research produced by others, this policy promotes the inclusion of multiple points of view. Consequently, this policy reinforces our neutrality policy. In many cases, there are multiple established views of any given topic. In such cases, no single position, no matter how well researched, is authoritative. It is not the responsibility of any one editor to research all points of view. But when incorporating research into an article, it is important that editors provide context for this point of view, by indicating how prevalent the position is, and whether it is held by a majority or minority.
The inclusion of a view that is held only by a tiny minority may constitute original research. Jimbo Wales has said of this:
If your viewpoint is in the majority, then it should be easy to substantiate it with reference to commonly accepted reference texts;
If your viewpoint is held by a significant minority, then it should be easy to name prominent adherents;
If your viewpoint is held by an extremely small minority, then — whether it's true or not, whether you can prove it or not — it doesn't belong in Wikipedia, except perhaps in some ancillary article. Wikipedia is not the place for original research
