}New documents are created without schema-defined fields. This means that a boolean field in your schema will not immediately result in documents containing the boolean key. The key must be assigned a value for it to appear in a document. Make sure your front-end code treats a missing boolean value as false.
Protip
In GROQ you can handle missing booleans and false values equally like this *[_type == 'story' && featured != true] which would match stories where featured is false or missing (or to be fair, any other value that is not true).
