In their paper titled, People systematically overlook subtractive changes, Adams and colleagues conduct a series of experiments where participants were asked to improve various designs, such as recipes, golf course layouts, travel itineraries, and Lego bridges. Despite scenarios where subtracting was the better strategy for improvement, participants overwhelmingly kept on adding to the designs. This tendency is likely due to the fact that people simply did not consider subtraction as a possibility and instead instinctively defaulted to adding. This may explain why individuals often find themselves adding more to their already busy schedules, or why some interventions cause more harm when they are introduced into a system.
