Overlooking Subtractive Solutions to Design Problems

Abstract

Do people systematically overlook opportunities to improve objects, ideas, and situations by subtracting from them? Eliminating features may enhance usability. Deleting words may clarify communications. Removing barriers may encourage desired behaviors. Yet, my research team and I have found that subtractive improvements are not as common as additive improvements in the changes that people pursue, and subtractive improvements are often overlooked entirely in the ideas that people generate. In our experiments, participants failed to identify advantageous subtractive improvements. This was true unless participants were explicitly prompted to consider subtration, given multiple opportunities (versus only one) to recognize the shortcomings of additive solutions, or when not cognitively burdened (verse under high cognitive load). Pursuing additive improvements without considering comparable, sometimes superior, subtractive ones may contribute to overburdened schedules, minds, and ecosystems.
