Collection description

At the beginning of its diffusion as a mass communication medium, the Internet had been enthusiastically saluted as a technology able to shift users from coordination models, based on hierarchical production and extrinsic market-driven incentives, to more effective, decentralized, collective, and intrinsically motivated peer to peer collaborations (Benkler, 2006; Castells, Fernández-Ardèvol, Qiu, & Sey, 2009; Levy, 1998; Malone & Klein, 2007; Tomlinson, 2007). Currently, several online platforms provide their users with opportunities and functionalities that support aggregation, membership, and interaction through connection, discussion, and content sharing. However, the literature on group thinking has consistently shown that interaction among members of a group can be conducive to dysfunctional dynamics that prejudice the development of individual and collective beliefs and choices. One of these dysfunctional dynamics is known whit the name of Group Polarization (GP) and refers to the tendency of groups to make decisions that are more extreme than the initial inclination of their members (Moscovici et al., 1972; Myers and Lamm, 1976). Over time, several studies have proved that GP can occur even when a group is not physically together, and that online groups are not immune to this form of group thinking, as well. The research work presented in this thesis explores the role of SM on the development of this particular dysfunctional group dynamic and its implications on human behaviors. In particular, we focused our attention on the role of online diversity in the development of GP and peoples' intention to act in sustain a cause in which they believe. Overall, while our results seem to mitigate the worrying echo-chambers consequences, they demonstrate that it would be naïve to believe that greater diversity could attenuate the emergence of GP or surely improve decision-making.
