Tendenz

Tendency writing is literature produced in order to promote a cause or serve a rhetorical purpose that the writing itself never makes explicit. These purposes are typically social, political, or moral. The name is borrowed from German forms such as Tendenzschrift, Tendenzroman ("tendency novel"), and Tendenzdrama.
