Wikipedia:Notability is not a level playing field

Goldington Road Stadium, Bedford, where the pitch has a pronounced slope and dip at one end. This photo doesn't show the pitch, but that doesn't really matter as this is an essay.

Notability is not a level playing field. This means that in certain areas, the inclusion requirements are lower than in others. This is related to the argument WP:OTHERSTUFFEXISTS - to the extent that an article within field (a) is included while a similar article in field (b) is deleted.

Reasons for this

Several possible reasons for this:

1. Wikis should generally be constructed in a hierarchical, top down manner, more notable subjects first. This combined with the fact that people write about what they're interested in, which might be unimportant, rather than what is assessed as important than a "professional" committee-written encyclopedia, means that Wikipedia is more complete in some areas than others.
2. Sources and research: Reliable sources are available to cover some areas more than others. Some areas have been researched and had that research published, others haven't.

Examples

• Politicians - moderate.
• Species: Many of which we can't know about because they're extinct and have left no fossil record or genetic heritage.
• Sports biographies - low see WP:NFOOTY and WP:NCRICKET

What to do about it

What should we do about it? Some suggestions:

1. Try to balance the playing field by lowering the notability requirements in some areas and raising them in others.
   • Note that doing this creates problems of what to do with existing content that previously met requirements but doesn't any more.
2. Carry on as before as you don't think this is a problem.
3. Write about what's important, not what you're interested in.
