how does Wikipedia decide what article is worth to write?

Wikipedia determines whether a topic is worth writing about primarily through the concept of notability. This requires that there be “a lot of in-depth coverage from well-regarded news sources demonstrating public interest in the topic”^[3]. Articles should focus on subjects that fulfill this criterion, ensuring significant information is available in reliable sources.

Moreover, content must adhere to Wikipedia's core policies, including writing from a neutral point of view and ensuring that information is publicly verifiable^[3][6]. By assessing the sources' integrity, Wikipedia editors decide if a proposed article meets the required standards for inclusion in the encyclopedia.
