Diversity

Importance
From Möller et al. (2018) : "Functioning democracies rely on the media's role to enable different groups and interests in society to participate in the democratic debate and create the opportunity for citizens to encounter diverse opinions (Owen & Smith, 2015 Owen, D., & Smith, G. (2015). Therefore, diversity is one of the core public values in media law and policy. As the Council of Europe (2007 Council of Europe (2007) has put it, ‘media pluralism and diversity of media content are essential for the functioning of a democratic society’ and the right to freedom of expression ‘will be fully satisfied only if each person is given the possibility to form his or her own opinion from diverse sources of information’."

Problem
People blame algorithms for creating "filter bubble".

Möller et al. (2018) suggest that algorithms are not worse than human editors in terms of diversity. Note, however, that they used synthetic data. Even if humans and algorithms are equally bad at preserving diversity, it doesn't mean that we don't have a problem. Algorithms bring recommendations to a much bigger scale, therefore exxacebate the problem.
