Abstract Starting from constructs' range of convenience as a central criterion, a model of the hierarchical organization of a personal construct system is developed by using elementary tools from set and graph theories. According to a radical constructivist point of view, constructs with their dichotomous nature are seen as the primitive objects, and the elements to which they apply are defined in terms of the constructs themselves. The difference between ordinal and logical relationships is made clear. The assumed structure permits a reconsideration of the notions of construct correlation, of predictive efficiency, and of invalidation and change in terms of the emergence of one or mare new constructs
