The authors argue that systems are designed to produce their results, even when their results are far from perfect. Systems also have internal “negative feedback processes” that maintain system stability by canceling out disruptions. Overcoming these stabilizing systems can be challenging, and pushing a system far enough to initiate change can result in sudden, highly disruptive shifts to a new system. Rather than cause such disruptive change, the authors advocate for incremental shifts to avoid the kind of wholesale disruption that could leave financial, social, and political systems in shambles.
