Contact, conflict, or opportunity? Out-group exposure creates tie opportunity, not tolerance
Mauritz N. Cartier van Dissel, Tomáš Lintner, Samuel Martin-Gutierrez +1
Three theories offer competing predictions about how people respond to growing diversity in their social environment. Contact theory suggests more exposure to out-groups reduces pr…
Impact of individual actions on the collective response of social systems
Samuel Martin-Gutierrez, Juan C. Losada, Rosa M. Benito
In a social system individual actions have the potential to trigger spontaneous collective reactions. The way and extent to which the activity (number of actions) of an individ…
Recurrent patterns of user behavior in different electoral campaigns: A Twitter analysis of the Spanish general elections of 2015 and 2016
Samuel Martin-Gutierrez, Juan C. Losada, Rosa M. Benito
We have retrieved and analyzed several millions of Twitter messages corresponding to the Spanish General elections held on the 20th of December 2015 and repeated on the 26th of Jun…
Relationship between ideology and language in the Catalan independence context
Julia Atienza-Barthelemy, Samuel Martin-Gutierrez, Juan C. Losada +1
Political polarization generates strong effects on society, driving controversial debates and influencing the institutions. Territorial disputes are one of the most important polar…
Large language models replicate and predict human cooperation across experiments in game theory
Andrea Cera Palatsi, Samuel Martin-Gutierrez, Ana S. Cardenal +1
Large language models (LLMs) are increasingly deployed as decision-making agents in high-stakes domains and as imitators of human behavior in the social and behavioral sciences. Ye…
Network Inequality through Preferential Attachment, Triadic Closure, and Homophily
Jan Bachmann, Samuel Martin-Gutierrez, Lisette Espín-Noboa +2
Inequalities in social networks arise from linking mechanisms, such as preferential attachment (connecting to popular nodes), homophily (connecting to similar others), and triadic…
hyperFA*IR: A hypergeometric approach to fair rankings with finite candidate pool
Mauritz N. Cartier van Dissel, Samuel Martin-Gutierrez, Lisette Espín-Noboa +2
Ranking algorithms play a pivotal role in decision-making processes across diverse domains, from search engines to job applications. When rankings directly impact individuals, ensu…
Mapping urban segregation through co-residence network reconstruction
Marc Sadurní, Samuel Martin-Gutierrez, Ola Ali +3
Urban segregation poses a critical challenge for cities, exacerbating inequalities, social tensions, fears, and polarisation. It emerges from the interplay of socio-economic dispar…
Intersectional inequalities in social networks
Samuel Martin-Gutierrez, Mauritz N. Cartier van Dissel, Fariba Karimi
Social networks are shaped by complex, intersecting identities that drive our connection preferences. These preferences weave networks where certain groups hold privileged position…
The hidden architecture of connections: How do multidimensional identities shape our social networks?
Samuel Martin-Gutierrez, Mauritz N. Cartier van Dissel, Fariba Karimi
Our multidimensional identities determine how we interact with each other, shaping social networks through group-based connection preferences. While interactions along single dimen…
Unveiling homophily beyond the pool of opportunities
Sina Sajjadi, Samuel Martin-Gutierrez, Fariba Karimi
Unveiling individuals' preferences for connecting with similar others (choice homophily) beyond the structural factors determining the pool of opportunities, is a challenging task.…
Multipolar social systems: Measuring polarization beyond dichotomous contexts
Samuel Martin-Gutierrez, Juan C. Losada, Rosa M. Benito
Social polarization is a growing concern worldwide, as it strains social relations, erodes trust in institutions, and thus threatens democratic societies. Academic efforts to under…
First-mover advantage explains gender disparities in physics citations
Hyunsik Kong, Samuel Martin-Gutierrez, Fariba Karimi
Mounting evidence suggests that publications and citations of scholars in the STEM fields (Science, Technology, Engineering and Mathematics) suffer from gender biases. In this pape…
Variance and covariance of distributions on graphs
Karel Devriendt, Samuel Martin-Gutierrez, Renaud Lambiotte
We develop a theory to measure the variance and covariance of probability distributions defined on the nodes of a graph, which takes into account the distance between nodes. Our ap…
