How digital media drive affective polarization through partisan sorting

Proceedings of the National Academy of Sciences, Год журнала: 2022, Номер 119(42)

Опубликована: Окт. 10, 2022

Politics has in recent decades entered an era of intense polarization. Explanations have implicated digital media, with the so-called echo chamber remaining a dominant causal hypothesis despite growing challenge by empirical evidence. This paper suggests that this mounting evidence provides not only reason to reject but also foundation for alternative mechanism. To propose such mechanism, draws on literatures affective polarization, and opinion dynamics. From polarization literature, we follow move from seeing as diverging issue positions rooted sorting: alignment differences which is effectively dividing electorate into two increasingly homogeneous megaparties. explain rise sorting, dynamics media research present model essentially turns its head: it isolation opposing views drives precisely fact bring us interact outside our local bubble. When individuals locally, outcome stable plural patchwork cross-cutting conflicts. By encouraging nonlocal interaction, drive conflicts along partisan lines, thus effacing counterbalancing effects heterogeneity. The result even if individual interaction leads convergence. polarize through creating maelstrom more identities, beliefs, cultural preferences become drawn all-encompassing societal division.

The future of theoretical evolutionary game theory

Philosophical Transactions of the Royal Society B Biological Sciences, Год журнала: 2023, Номер 378(1876)

Опубликована: Март 20, 2023

Evolutionary game theory is a truly interdisciplinary subject that goes well beyond the limits of biology. Mathematical minds get hooked up in simple models for evolution and often gradually move into other parts evolutionary biology or ecology. Social scientists realize how much they can learn from thinking transfer insight was originally generated Computer use their algorithms to explore new field where machines not only environment, but also each other. The breadth focus on few very popular issues, such as cooperation, comes at price: several insights are re-discovered different fields under labels with heroes modelling traditions. For example, reciprocity spatial structure treated differently. Will we continue develop things parallel? Or converge single set ideas, tradition eventually software repository? will these cross-fertilize other, learning engaging constructive exchange between fields? Ultimately, popularity rests its explanatory power, intuitive character models. This article part theme issue ‘Half century games: synthesis theory, application future directions’.

Information and communication technologies hold immense potential to enhance our lives societal well-being. However, digital spaces have also emerged as a fertile ground for fake news campaigns hate speech, aggravating polarization posing threat harmony. Despite the fact that this dark side is acknowledged in literature, complexity of phenomenon coupled with socio-technical nature necessitates novel approach unravel its intricacies. In light sophistication, current study employs theory configurational investigate impact diverse disinformation speech polarizing societies across 177 countries through cross-country investigation. The results demonstrate definitive role societies. findings offer balanced perspective on internet censorship social media monitoring necessary evils combat menace control polarization, but suggest such efforts may lend support milieu fuels polarization.

The Polarization of Popular Culture: Tracing the Size, Shape, and Depth of the Oil Spill

Опубликована: Сен. 1, 2022

Recent research suggests that political polarization has spilled over into otherwise mundane areas of social life. And yet, the size, shape, and depth spillage popular culture is generally unknown. Relying on a sample 135 most widely known movies, TV shows, musicians, sports, leisure activities, we investigate this question. We find oil spill large but loosely organized multiple fairly shallow pools. Cultural also asymmetric. Liberals like wide variety culture, do not dislike conservative their tastes are more rooted in sociodemographics. Conservatives, other hand, much narrower range created liked by Black urban liberals, directly ideology. Potential implications an asymmetric war, ideas for future research, discussed.

Polarization in the United States and around world is of growing concern. about more than just differences opinions society. It occurs when groups increasingly diverge either actual or perceived opinion can involve both disagreements issues negative views other groups. Since most environmental problems are collective action problems, polarization may interfere with kinds deliberation collaborations needed for effective decision-making. In this review, we examine how influences decision-making what strategies could be useful preventing reducing consequences polarization.

Evolution of norms for judging social behavior

Proceedings of the National Academy of Sciences, Год журнала: 2023, Номер 120(24)

Reputations provide a powerful mechanism to sustain cooperation, as individuals cooperate with those of good social standing. But how should someone’s reputation be updated we observe their behavior, and when will population converge on shared norm for judging behavior? Here, develop mathematical model cooperation conditioned reputations, that is stratified into groups. Each group may subscribe different assessing reputations so norms compete choose move from one another. We show initially comprising minority the nonetheless overtake entire population—especially if it adopts Stern Judging norm, which assigns bad who When do not change membership, stratifying information groups tends destabilize unless are strongly insular favor in-group interactions. discuss implications our results structure flow in evolution judgment.

Polarization is common in politics and public opinion. It believed to be shaped by media as well ideologies, often incited misinformation. However, little known about the microscopic dynamics behind polarization resulting social tensions. By coupling opinion formation with strategy selection different dilemmas, we reveal how success at an individual level transforms global consensus or lack thereof. When defection carries it fear of punishment absence greed, stag-hunt game, fragmentation smallest. Conversely, if promises a higher payoff also evokes like prisoner's dilemma snowdrift more difficult attain.

Exotic swarming dynamics of high-dimensional swarmalators

Physical review. E, Год журнала: 2024, Номер 109(4)

Опубликована: Апрель 24, 2024

Swarmalators are oscillators that can swarm as well sync via a dynamic balance between their spatial proximity and phase similarity. Swarmalator models employed so far in the literature comprise only one-dimensional variables to represent intrinsic dynamics of natural collectives. Nevertheless, latter indeed be represented more realistically by high-dimensional variables. For instance, alignment velocity vectors school fish or flock birds set up three-dimensional space, while opinion formation population could multidimensional, general. We present generalized D-dimensional swarmalator model, which accurately captures self-organizing behaviors plethora real-world collectives self-adaptation sensible visualization interpretation results, we restrict our simulations Our model provides framework for modeling complicated processes such flocking, schooling fish, cell sorting during embryonic development, residential segregation, social groups. demonstrate its versatility capturing maneuvers qualitatively quantitatively, suitable extension original incorporate appropriate features besides gallery self-organizations various interactions. expect proposed potentially useful describing swarming systems programmable reconfigurable wide range disciplines, including physics active matter, developmental biology, sociology, engineering.

While many believe that affective polarisation poses a significant threat to democratic stability, the definition and operationalisation of concept varies greatly. This leads conceptual slippage as well imprecise tests causes consequences polarisation. In order clearly identify target its micro-foundations, we must understand degree which political divides are, in fact, affective. this paper, do so. We begin by delineating polarisation, social divide is purportedly distinct from policy-based disagreements. Subsequently, explore influence emotions politics, including how affect conceptualised within framework Where possible, our literature review supplemented with analyses existing datasets support points.

The drivers of online polarization: Fitting models to data

Information Sciences, Год журнала: 2023, Номер 642, С. 119152 - 119152

Опубликована: Май 18, 2023

Users online tend to join polarized groups of like-minded peers around shared narratives, forming echo chambers. The chamber effect and opinion polarization may be driven by several factors including human biases in information consumption personalized recommendations produced feed algorithms. Until now, studies have mainly used dynamic models explore the mechanisms behind emergence objective was determine key contributing these phenomena identify their interplay. However, validation model predictions with empirical data still displays two main drawbacks: lack systematicity qualitative analysis. In our work, we bridge this gap providing a method numerically compare distributions obtained from simulations those measured on social media. To validate procedure, develop an that takes into account interplay between algorithmic factors. We subject testing diverse media platforms benchmark it against state-of-the-art models. further enhance understanding platforms, provide synthetic description characteristics terms model's parameter space. This representation has potential facilitate refinement algorithms, thus mitigating detrimental effects extreme discourse.
