ABSTRACT: There is an ongoing debate about whether recommender systems could produce a social disintegration, that is break the society into separate hubs of homogeneous individuals, with no communication channel between them. The reason behind such a dystopian outcome is that recommender systems would fuel individuals’ homophily. Building on a computer simulation model of knowledge exchange among homophilous agents, we find that a society break does emerge in the case of extreme homophily. While some scholars advocate for a redesign of recommender systems, we rather propose to focus on maximizing people’s opportunities to benefit from serendipity, that is to be confronted with unexpected knowledge, especially in the off-line world, for instance when getting involved into a thrid place, like a public library. Indeed, simulations suggest that extremely homophilous agents can still produce a society-wide network of knowledge exchange when some of their knowledge bits get modified unexpectedly.
