Wikipedia:An interest is not a conflict of interest

Conflict of interest is a cause not a crime.

Conflict of interest is one of Wikipedia's least understood and yet most cited behavioral guidelines. In a nutshell it strongly discourages promoting interests an editor is related to unless it is certain that the interests of Wikipedia remain paramount.

Conflicted editors can be an extremely valuable and largely untapped resource as they are often the most equipped and motivated to report on a given subject. Policy permits conflicted editors to edit articles provided they comply with other policies. Unfortunately some such editors fail to write from a neutral point of view, introduce original research or unverifiable claims, link to third-party websites or breach other policies and guidelines such as those dealing with autobiographies.
