A wicked problem is a social or cultural problem that is difficult or impossible to solve for as many as four reasons: incomplete or contradictory knowledge, the number of people and opinions involved, the large economic burden, and the interconnected nature of these problems with other problems. Poverty is linked with education, nutrition with poverty, the economy with nutrition, and so on. These problems are typically offloaded to policy makers, or are written off as being too cumbersome to handle en masse. Yet these are the problems—poverty, sustainability, equality, and health and wellness—that plague our cities and our world and that touch each and every one of us. These problems can be mitigated through the process of design, which is an intellectual approach that emphasizes empathy, abductive reasoning, and rapid prototyping.
Horst Rittel, one of the first to formalize a theory of wicked problems, cites ten characteristics of these complicated social issuesRittel, Horst. "Dilemmas in a General Theory of Planning." Policy Sciences, 1973: 155-169.:
Based on these characteristics, not all hard-to-solve problems are wicked, only those with an indeterminate scope and scale. So most social problems—such as inequality, political instability, death, disease, or famine—are wicked. They can't be "fixed." But because of the role of design in developing infrastructure, designers can play a central role in mitigating the negative consequences of wicked problems and positioning the broad trajectory of culture in new and more desirable directions. This mitigation is not an easy, quick, or solitary exercise. While traditional circles of entrepreneurship focus on speed and agility, designing for impact is about staying the course through methodical, rigorous iteration. Due to the system qualities of these large problems, knowledge of science, economics, statistics, technology, medicine, politics, and more are necessary for effective change. This demands interdisciplinary collaboration, and most importantly, perseverance.
