This paper presents a case study about the responsible design of a recommender system of a prominent Dutch Public Service Media (PSM) organization, combining personalized content recommendations to users while aligning with the organization’s overarching mission of fostering diversity. A conceptual framework of diversity in news recommenders was translated into four possible prototypes of recommender systems, representing different ways to strike a balance between the objectives of personalization and diversity. These prototypes were presented to PSM stakeholders with different expertise, aiming to increase their insight into practical consequences of different conceptual choices, thus facilitating their communication and decision processes.
