This study explores the determinants of popularity within friendship and advice networks.We involved almost two hundreds college students in an experiment to predict how personality traits, self-monitoring, creativity, intelligence, energy, and beauty influence the development of friendship and advice networks. Our results indicate that physical attractiveness is key to develop both friendship and task-related interactions, whereas perceived intelligence and creativity play an important role in the advice network. Our findings seem to support the idea that there might be a kernel of truth in the stereotype that attractiveness correlates with positive social traits and successful outcomes.The paper is organized as follows. In the next section, we review the literature on the main determinants of popularity and then we present the hypotheses ( §2). After describing how data was collected and variables measured ( §3), we present the results of the analyses ( §4). We conclude by discussing the main implications of the findings, the limitations of our study, and important topics for future research ( §5 and §6).
Homophily and Determinants of PopularityPsychological studies in the area of social cognition (Fiske et al., 2006) suggest that human social perception is influenced by two main factors: liking, which captures traits like friendliness and sociability; and respecting, which captures factors like intelligence, competence, and efficiency. More recent research gave evidence to the possible interdependence of friendship and advice-related interactions between individuals (Kilduff, 1990;Snijders et al., 2013). For example, Snijders et al. (2013) suggested that in the advice network homophily, defined as the individuals' tendency to choose to connect with others exhibiting similar attributes, is mediated by friendship relations which are influenced by mutual attraction. Similarly, in our study we focus on the co-evolution of friendship and advice relationships, taking into account the way they influence one another.We define the advice network as a set of "relations through which individuals share resources such as information, assistance, and guidance" (Sparrowe et al., 2001, p.317). The friendship network is defined by the ties of affection and companionship that connect individuals (Baldwin et al., 1997). We rely on the methodologies and techniques of social network analysis to operationalize individual's centrality within a network (Wasserman and Faust, 1994). There
