Wikipedia:Articles for deletion/The Spark: A Mother's Story of Nurturing Genius
The reason Wikipedia requires reliable independent secondary sources is that reliable journals and reliable journalism have fact-checking protocols. Larger journalistic enterprises hire fact-checkers whose job it is to ensure they publish accurately the details of each story, or they have other sourcing protocols reporters must follow. Wikipedia relies on secondary sources that are fact-checked, because Wikipedia does not have professional fact checkers, just us, the editors who write and revise articles. The Wikipedia:Identifying_reliable_sources#Overview|Overview section of the |guideline includes this statement:  {{tq|Source reliability falls on a spectrum: highly reliable sources, clearly unreliable sources, and many in the middle. Editors must use their judgment to draw the line between usable and unreliable sources.}} Note the verb ''must'' in that last sentence
— NONE, NONE
