“…In the world of big data, however, we find the explicit recognition that personality does not exist in a vacuum. In the digital realm, people do not merely behave, they interact with dynamic environmental factors that can also be measured-other people (Davidson, Jones, Joinson, & Hinds, 2019;Pan, Altshuler, & Pentland, 2012), games (Canossa, Badler, El-Nasr, Tignor, & Colvin, 2015), web pages (Shobeiri, Laroche, & Mazaheri, 2013;Turkyilmaz, Erdem, & Uslu, 2015), smartphone apps (Miller, 2012), and so on. Social context parameters such as network size, centrality (position or role), and local transitivity (connectedness among friends) are associated with personality (Fang et al, 2015;Gosling, Augustine, Vazire, Holtzman, & Gaddis, 2011;Staiano et al, 2012), and traits such as cooperation are at least in part emergent properties of context, dependent upon community structure (Apicella, Marlowe, Fowler, & Christakis, 2012).…”
