This paper aims to analyze learning as a two-type process. A dynamic equilibrium process represents a stable learning process, that may express an individualistic behavioral learning or an organizational adaptation. A teleological process represents an intentional, goal-oriented, learning process. This second type of learning can express an individualistic cognitive learning or a managerial organizational change. It is argued that this learning typology can helps to understand why similar organizations or individuals may learn differently when confronted to the same environmental stimuli.
