The purpose of this paper is to propose an enlarged framework for defining and evaluating knowledge risk, by changing the paradigm of cognitive knowledge with that of the multifield theory of knowledge. So far, knowledge risk has been considered only from the perspective of explicit knowledge (i.e. rational knowledge) and tacit knowledge (i.e. experience). However, the concept of knowledge has been enriched with the multifield theory of knowledge which considers three fundamental forms of knowledge: rational, emotional, and spiritual. These three fields of knowledge imply a larger framework of defining and evaluating the knowledge risk. We propose a metaphorical approach in defining the knowledge spectrum and a critical thinking analysis in explaining the new dimensions of knowledge risk. The knowledge dynamics theory created by Ikujiro Nonaka is based on the iceberg metaphor, which considers only two forms of knowledge: explicit and tacit. Based on this metaphor, the knowledge risk framework has two dimensions: the explicit dimension used for the rational knowledge and the tacit dimension used for the experiential or know-how knowledge. The present paper introduces the energy metaphor for knowledge and defines the knowledge risk framework considering three dimensions: rational, emotional and spiritual. This methodology allows an enlarged and more realistic framework for the knowledge risk definition and evaluation. The energy metaphor allows for an entropic knowledge dynamics and better approach in the managerial decision-making in order to reduce the organizational knowledge risk. The outcomes of the application contributes to creating a sustainable knowledge management by developing new dynamic capabilities in evaluating the organizational knowledge risk and reducing its probable negative consequences. By using this approach mangers can realize a better balance of the organizational knowledge creation, acquisition and loss. Also, managers can design a better motivational system along the emotional dimension of the organizational knowledge, and improve the level of corporate social responsibility along the spiritual dimension of the organizational knowledge.
