14ALL (19/08/2019 – 18/08/2022) is a Research Project of National Relevance (PRIN) funded by the Italian Ministry of Education, University and Research. It aims to investigate the conditions under which groups may trigger aggressive behavior in individual members and fuel retaliatory cycles magnifying the consequences of inter-group conflict.

14ALL adopts a set of complementary research methods, consisting of laboratory experiments, survey experiments and agent-based simulations, to investigate mechanisms underlying inter-group conflict.

First, we will use a laboratory experiment to determine when group membership and group reputation promote aggression. Second, we will conduct a survey experiment on a representative sample of the national population to investigate when vengeful or forgiving behavior is socially rewarded by the group. Third, we will develop an empirically calibrated agent-based model to simulate large-scale implications, test findings generalizability and support counterfactual analysis.

Findings and simulation tools will be presented to stakeholders to explore policies aiming to mitigate intergroup conflict in various settings, such as inter-ethnic conflicts, political extremism, and hooliganism.

The PI of the project is Davide Barrera. Giulia Andrighetto coordinates the LABSS-ISTC unit and Flaminio Squazzoni coordinates the UniMi unit.
