  News diversity in the media has for a long time been a foundational and
uncontested basis for ensuring that the communicative needs of individuals and
society at large are met. Today, people increasingly rely on online content and
recommender systems to consume information challenging the traditional concept
of news diversity. In addition, the very concept of diversity, which differs
between disciplines, will need to be re-evaluated requiring a interdisciplinary
investigation, which requires a new level of mutual cooperation between
computer scientists, social scientists, and legal scholars. Based on the
outcome of a multidisciplinary workshop, we have the following recommendations,
directed at researchers, funders, legislators, regulators, and the media
industry: 1. Do more research on news recommenders and diversity. 2. Create a
safe harbor for academic research with industry data. 3. Optimize the role of
public values in news recommenders. 4. Create a meaningful governance
framework. 5. Fund a joint lab to spearhead the needed interdisciplinary
research, boost practical innovation, develop. reference solutions, and
transfer insights into practice.
