Small changes are appealing for many reasons. They’re cheap, for one thing. Also, what works can be easily expanded, and what doesn’t work can be as easily terminated or altered. One successful food concession can become two; an unsuccessful stall selling local crafts can be replaced; a planter made from a material that discolors or chips can be replaced with a better one. Contrast that with grand schemes, which can attract broad opposition and be subject to complex political, logistical, and financial obstacles. Once an elaborate design has been committed to, backing away from it—or even altering it—becomes both politically and mechanically complicated. Further, planners have a limited capacity to predict how people will respond to their designs. The larger the project, the more likely unintended consequences become, and the more difficult it is to change course.
