Descriptions are models. All models have a validity-property, validity is a property that describes how well the model manages to model the thing that it is modeling. The less validity a model has, the more "wrong" it is. A description of the earth as flat, seamingly has a lower validity than a description as the earth as a perfect sphere. But ultimately it depends on how one measures validity.
