Engineering design entails making value-laden judgments against ill-defined, ambiguous, and/or competing sociotechnical criteria. In this article, we argue that such conditions make engineering designers particularly susceptible to the potentially deleterious effects of mis/disinformation in the processes and practices of engineering design, their engagement with people and communities, and in the production and evaluations of the artifacts they produce. We begin by critiquing dominant approaches to engineering design education, specifically, engineering education's social-technical dualism and the ubiquitous ideology of depoliticization, which has exacerbated the effects of mis/disinformation in engineering design. We follow by outlining a framework for developing students' capacity for mitigating its effects in the specific context of engineering design thinking and making value-laden engineering judgments and decision-making. We envision three areas of opportunity for engineering design education to teach students strategies for navigating these challenges when engaging with (a) the processes and practices of engineering, which reflect the unique types of information students engage with across the design process, (b) people and their communities, including the strategic and careful performance of activities for gathering information, while mitigating the harms to misinformation and disinformation and maximizing the benefits of community involvement, and (c) the social and technical criteria of engineering design outcomes in the form of artifacts (e.g., products, processes).
