Consolidation and Change: Exploring the Impact of Anger and Network Dynamics on Inequality Belief Systems

Published in Network Science, 2025

Uses network models and simulations on the 2019 ISSP Social Inequality module to show how anger strengthens and polarises US inequality belief systems and how changes in central attitudes can propagate through the system.

Conspiracy Theories Are Central to the Complex System of Predictors of Italian Vaccine Hesitancy

Published in Italian Political Science, 2026

talks

1st ISSP User Conference on Social Inequality: Overcoming the structuralist/individualist dichotomy (Franetovic and Bertero)

Published:

In December 2022 Gonzalo Franetovic and I were pleased to present at the 1st ISSP User Conference on Social Inequality. We showed how Exploratory Graph Analysis can be leveraged to isolate at least three dimensions of inequality beliefs in the vast majority of the ISSP countries. This represents an important finding since most of the literature was anchored to the structuralist/individualist dichotomy. The pdf of the presentation can be found here.

Chilean Social Network Conference (CHISOCNET): How do people understand inequality in Chile? (Franetovic and Bertero)

Published:

In January 2023 Gonzalo Franetovic and I were pleased to present at CHISOCNET. We adopted network analysis on attitudes toward inequality to investigate how people understand this complex socio-political phenomenon in Chile. Results show that these attitudes are part of a single belief system and that people from lower social status positions have a more multidimensional understanding of inequality. You can find the slides here.

SISEC Conference: Modelling, estimating, simulating. Formalizing attitudes towards inequality as a complex network (Bertero and Franetovic)

Published:

At the beginning of 2023, we presented at the conference of the Italian Society of Economic Sociology (SISEC). We modeled attitudes toward inequality as a complex system. We further estimated structural differences in these attitudes across different social groups; Finally, we simulated attitudinal change to show how they are likely to develop over time. Here are the slides!

ECPR Conference: Modelling, estimating, simulating (II) (Bertero and Franetovic)

Published:

As a political scientist, ECPR is very important to me! In Toulouse, I presented a refined version of the work “Modelling, estimating, simulating”, which me and Gonzalo originally presented at SISEC. We were in the fantastic panel “Network of Political Beliefs”, chaired by Lorien Jasny and Claudia Zucca. It was an incredible pleasure to receive expert feedback and get in contact with extraordinary researchers from all over the world. Slides are available here!

CCA Days: Conspiracy theories are central to the complex system of predictors of Italian vaccine hesitancy

Published:

In June 2023 I presented at the CCA Days, a workshop jointly organized by NASP and Collegio Carlo Alberto. I had the pleasure of presenting research on Italian vaccine hesitancy. The literature on the topic usually conceives hesitancy as a dependent variable of regression models of limited sizes, adopting a reductionist approach. To mitigate this limitation, I try to study hesitancy as an emergent phenomenon whose state depends on the intricate relationships occurring between its predictors. In the results, I show that this behavior is strongly influenced by a restricted list of variables that I label empirical predictors. This can help design effective intervention strategies. Slides are available here
