Human beings interact with complex systems very successfully. We do it all the time. But we do it by managing them, not by claiming to understand them. Managers interact with the system: they do something, watch for the response, and then do something else in an effort to get the result they want. There is an endless iterative interaction that acknowledges we don’t know for sure what the system will do—we have to wait and see. We may have a hunch we know what will happen. We may be right much of the time. But we are never certain.
