Verifiability does not guarantee inclusion
While information must be verifiable in order to be included in an article, this does not mean that all verifiable information must be included in an article. Consensus may determine that certain information does not improve an article, and that it should be omitted or presented instead in a different article. The onus to achieve consensus for inclusion is on those seeking to include disputed content.
Tagging a sentence, section, or article
If you want to request a source for an unsourced statement, you can tag a sentence with the or removed. When using templates to tag material, it is helpful to other editors if you explain your rationale in the template, edit summary, or on the talk page.
Take special care with material about living people. Contentious material about living people that is unsourced or poorly sourced should be removed immediately, not tagged or moved to the talk page.
Exceptional claims require exceptional sources
Any exceptional claim requires multiple high-quality sources. Red flags that should prompt extra caution include:
- surprising or apparently important claims not covered by multiple mainstream sources;
- challenged claims that are supported purely by primary or self-published sources or those with an apparent conflict of interest;
- reports of a statement by someone that seems out of character, or against an interest they had previously defended;
- claims that are contradicted by the prevailing view within the relevant community, or that would significantly alter mainstream assumptions, especially in science, medicine, history, politics, and biographies of living people. This is especially true when proponents say there is a conspiracy to silence them.
