Here, we introduce a model of public opinion expression. Two groups of agents with different opinion on an issue interact with each other, changing the willingness to express their opinion according to whether they perceive themselves as part of the majority or minority opinion. We formulate the model as a multigroup majority game and investigate the Nash equilibria. We also provide a dynamical systems perspective: Using the reinforcement learning algorithm of Q-learning, we reduce the N-agent system in a mean-field approach to two dimensions which represent the two opinion groups. This two-dimensional system is analyzed in a comprehensive bifurcation analysis of its parameters. The model identifies social-structural conditions for public opinion predominance of different groups. Among other findings, we show under which circumstances a minority can dominate public discourse. 2020 true true true false false NONE 2023-07-27 false 0 0 0 0 0 0 0 0 0 0 0 0 2 2 Q1 false false false false 2023-10-25T12:42:38.728+0000 3 25 0 3 0 true Language 10002 /api/language/10002 Angol English true 2 true PersonAuthorship 94579450 /api/authorship/94579450 1 0.0 true false true Gaisbauer Felix true false false AuthorshipType 1 /api/authorshiptype/1 0 true 0 true false true PersonAuthorship 94579451 /api/authorship/94579451 2 0.0 false false false Olbrich Eckehard true false false AuthorshipType 1 /api/authorshiptype/1 0 true 0 true false true PersonAuthorship 94579452 /api/authorship/94579452 3 0.0 false true false Banisch Sven true false false AuthorshipType 1 /api/authorshiptype/1 0 true 0 true false true PublicationIdentifier 18132607 /api/publicationidentifier/18132607 PlainSource 6 /api/publicationsource/6 PublicationSourceType 10001 /api/publicationsourcetype/10001 true true true DOI DOI https://doi.org/@@@ true true 6 true IDENTICAL 10.1103/PhysRevE.102.042303 https://doi.org/10.1103/PhysRevE.102.042303 false true PublicationIdentifier 18132606 /api/publicationidentifier/18132606 PlainSource 1 /api/publicationsource/1 PublicationSourceType 10003 /api/publicationsourcetype/10003 false true true WoS WoS https://www.webofscience.com/wos/woscc/full-record/@@@ true true 1 true IDENTICAL 000577084700002 https://www.webofscience.com/wos/woscc/full-record/000577084700002 false true PublicationIdentifier 18132608 /api/publicationidentifier/18132608 PlainSource 3 /api/publicationsource/3 PublicationSourceType 10003 /api/publicationsourcetype/10003 false true true Scopus http://www.scopus.com/record/display.url?origin=inward&eid=2-s2.0-@@@ true true 3 true IDENTICAL 85093089134 http://www.scopus.com/record/display.url?origin=inward&eid=2-s2.0-85093089134 false true PublicationIdentifier 18132609 /api/publicationidentifier/18132609 PlainSource 17 /api/publicationsource/17 PublicationSourceType 10003 /api/publicationsourcetype/10003 false true true PubMed PubMed http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=PubMed&list_uids=@@@&dopt=Abstract true true 17 true IDENTICAL 33212677 http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=PubMed&list_uids=33212677&dopt=Abstract false true Classification 10154 /api/classification/10154 true true Classification 10003 /api/classification/10003 true true SjrRating 11001716 /api/sjrrating/11001716 80 0.24 journal RatingType 10002 /api/ratingtype/10002 sjr true true ClassificationExternal 3104 /api/classificationexternal/3104 true 3104 true Q1 DIRECT true true /api/publication/31746897 <div class="JournalArticle Publication long-list"> <div class="authors"> <img title="Idézőközlemény" style="float: left" src="/frontend/resources/grid/publication-citation-icon.png"> <div class="autype autype0"> <span class="author-name" >Gaisbauer Felix ✉ </span> ;&nbsp;&nbsp;&nbsp;
