Cognitive ontologies have been primarily developed in a top-down manner on the basis of psychological theories that lean heavily upon folk psychological concepts. I will first assess the degree to which these ontologies are effective in predicting brain activity using cognitive encoding models, showing that they are surprisingly effective but also highlighting some important shortcomings. I will then ask whether we might develop better understanding of the organization of the mind through bottom-up, or “data driven” ontologies. I will present two examples of such data-driven ontologies, outlining their success but also detailing important limitations on this approach.
