Writing studies must conduct replicable, aggregable, and data-supported (RAD) research to understand the relationship between creativity and writing, including how writers use creative thinking to generate texts and how environmental factors mediate writers’ engagement with creative thinking. This article traces research on creativity from selected writing studies journals since the 2011 release of The Framework for Success in Postsecondary Writing. Through a systematic literature review, the findings show how RAD research supports domain-specific knowledge-building about writers’ creativity, which can help teachers, scholars, and practitioners to understand what counts as originality in writing, how writers produce creative texts, and how educational institutions can teach advanced writing skills that develop students’ creative thinking.
