Study of how we come to know—the nature of modeling and anticipation of our unpredictable, often dangerous environment—is the province of evolutionary epistemology. Constructivism depends upon knowledge being static or non-evolutionary and therefore cannot address the unforeseen and unknown in either our behavior or acquisition of knowledge. It has no anticipatory or feedforward mechanisms for the unanticipated. Likewise, constructivism has no mechanism for addressing error—either its detection or correction. Social or market orders (e.g., science) are sources of information used by agents to generate knowledge and to detect error. Trying to control science or the market by top-down intervention falsifies knowledge claims, fails to detect error, and reduces productivity in society. Socialism is not scientific, it kills inquiry by controlling its output.KeywordsAnticipatory systemsError eliminationCreativityControl
