Some researchers state that Bhutan's GNH philosophy "has evolved over the last decade through the contribution of western and local scholars to a version that is more democratic and open. Therefore, probably, the more accurate historical reference is to mention the coining of the GNH phrase as a key event, but not the Bhutan GNH philosophy, because the philosophy as understood by western scholars is different from the philosophy used by the King at the time." Other viewpoints are that GNH is a process of development and learning, rather than an objective norm or absolute end point. Bhutan aspires to enhance the happiness of its people and GNH serves as a measurement tool for realizing that aspiration.
