To bridge this gap here we introduce a higher-order framework that takes into account both group interactions and homophily. We find that group interactions can strongly enhance polarization in sparse systems by limiting agents’ exposure to dissenting views. Conversely, they can suppress polarization in fully connected societies, an effect that intensifies as the group size increases. Our results highlight that polarization depends not only on the homophily strength but also on the structure and microscopic arrangement of group interactions. 000165867 536__ $$9info:eu-repo/grantAgreement/ES/DGA/E36-23R-FENOL$$9info:eu-repo/grantAgreement/ES/MICINN/PID2020-113582GB-I00$$9info:eu-repo/grantAgreement/ES/MICINN/PID2021-128005NB-C21$$9info:eu-repo/grantAgreement/ES/MICINN/PID2023-147734NB-I00 000165867 540__ $$9info:eu-repo/semantics/openAccess$$aby-nc-nd$$uhttps://creativecommons.org/licenses/by-nc-nd/4.0/deed.es 000165867 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000165867 700__ $$aLamata-Otín, Santiago$$uUniversidad de Zaragoza 000165867 700__ $$aMalizia, Federico 000165867 700__ $$0(orcid)0000-0002-1406-8810$$aFloría, Luis Mario$$uUniversidad de Zaragoza 000165867 700__ $$0(orcid)0000-0001-5204-1937$$aGómez-Gardeñes, Jesús$$uUniversidad de Zaragoza 000165867 700__ $$0(orcid)0000-0002-6388-4056$$aSoriano-Paños, David 000165867 7102_ $$12003$$2395$$aUniversidad de Zaragoza$$bDpto.
