it pains me to quote mr wales but this is actually quite clear from jimbo wales paraphrased from this post from september on the mailing list if a viewpoint is in the majority then it should be easy to substantiate it with reference to commonly accepted reference texts if a viewpoint is held by a significant minority then it should be easy to name prominent adherents if a viewpoint is held by an extremely small or vastly limited minority it does not belong in wikipedia regardless of whether it is true or not and regardless of whether you can prove it or not except perhaps in some ancillary article keep in mind that in determining proper weight we consider a viewpoint's prevalence in reliable sources not its prevalence among wikipedia editors if you are able to prove something that few or none currently believe wikipedia is not the place to premiere such a proof once a proof has been presented and discussed elsewhere however it may be referenced see wikipedia no original research and wikipedia verifiability
