for the climate challenge. Then, as now, entrenched special interests vigorously opposed change. … Of course, we need more research and technical innovation—money and genius are always in short supply. But there is no purely technical solution for climate change. For public policy to be grounded in the hard-won results of climate science, we must now turn our attention to the dynamics of social and political change." These findings indicate there are at least two subproblems to be solved: change resistance and proper coupling. Given the human system's long history of unsuccessful attempts to self-correct to a sustainable mode, it appears that high change resistance is preventing proper coupling. This may be expressed as an emerging principle: systemic change resistance is the crux of the sustainability problem and must be solved first, before the human system can be properly coupled to the greater system it lives within, the environment. Systemic versus individual change resistance Systemic change resistance differs significantly from individual change resistance. "Systemic means originating from the system in such a manner as to affect the behavior of most or all social agents of certain types, as opposed to originating from individual agents." Individual change resistance originates from individual people and organizations. How the two differ may be seen in this passage: "The notion of resistance to change is credited to Kurt Lewin. His conceptualization of the phrase, however, is very different from today's usage. [which treats resistance to change as a psychological concept, where resistance or support of change comes from values, habits, mental models, and so on residing within the individual] For Lewin, resistance to change could occur, but that resistance could be anywhere in the system. As Kotter (1995) found, it is possible for the resistance to be sited within the individual, but it is much more likely to be found elsewhere in the system. "Systems of social roles, with their associated patterns of attitudes, expectations, and behavior norms, share with biological systems the characteristic of homeostasis—i.e., tendencies to resist change, to restore the previous state after a disturbance. "Lewin had been working on this idea, that the status quo represented an equilibrium between the barriers to change and the forces favoring change, since 1928 as part of his field theory. He believed that some difference in these forces—weakening of the barriers or strengthening of the driving forces—was required to produce the unfreezing that began a
