Majority Correctness in Social Networks: From Well-Mixed Electorates to Complex Networks
Dan Braha, Marcus A. M. de Aguiar
The paper investigates how repeated social interactions on various network structures affect the likelihood that a majority vote selects the objectively correct option, using a zea…
Selection Mechanisms, Stationary Distributions, and Reversibility in Multiallelic Moran Models
Dan Braha, Marcus A M de Aguiar
The Moran process with selection and recurrent mutation is a classical model in population genetics, yet how the placement of selection within the update rule shapes the stationary…
The multi-allelic Moran process as a multi-zealot voter model: exact results and consequences for diversity thresholds
Dan Braha, Marcus A. M. de Aguiar
The Moran process is a foundational model of genetic drift and mutation in finite populations. In its standard two-allele form with population size , allele counts, and hence al…
Interplay of sync and swarm: Theory and application of swarmalators
Gourab Kumar Sar, Kevin O'Keeffe, Joao U. F. Lizarraga +3
Swarmalators, entities that combine the properties of swarming particles with synchronized oscillations, represent a novel and growing area of research in the study of collective b…
Generalizing Condorcet's Jury Theorem to Social Networks
Dan Braha, Marcus A. M. de Aguiar
We generalize Condorcet's jury theorem (CJT) to socially connected populations in which agents revise discrete choices on a network in the presence of zealots. Free agents receive…
Emergence of Collective Accuracy in Socially Connected Networks
Dan Braha, Marcus A. M. de Aguiar
We analyze the accuracy of collective decision-making in socially connected populations, where agents update binary choices through local interactions on a network. Each agent rece…
