Design Research Failures is a design research project that facilitates conversation, reflection and action around the question: “In what way has Design Research failed in the last 50 years?” In this article, the project is further discussed as a potential vehicle for making and unmaking design history in various ways. As a call for action for design historians to engage in this exploration, two examples of such possible engagements are included, one by Kaisu Savola and another by Ben Highmore.
