# Consensus time in a voter model with concealed and publicly expressed opinions

@article{Gastner2018ConsensusTI, title={Consensus time in a voter model with concealed and publicly expressed opinions}, author={Michael T. Gastner and Be{\'a}ta Oborny and M{\'a}t{\'e} Guly{\'a}s}, journal={Journal of Statistical Mechanics: Theory and Experiment}, year={2018}, volume={2018} }

The voter model is a simple agent-based model to mimic opinion dynamics in social networks: a randomly chosen agent adopts the opinion of a randomly chosen neighbour. This process is repeated until a consensus emerges. Although the basic voter model is theoretically intriguing, it misses an important feature of real opinion dynamics: it does not distinguish between an agent’s publicly expressed opinion and her inner conviction. A person may not feel comfortable declaring her conviction if her…

The voter model is an archetypal stochastic process that represents opinion dynamics. In each update, one agent is chosen uniformly at random. The selected agent then copies the current opinion of a…

According to the results, hypocrisy always prolongs the time needed for reaching a consensus and the initial abundances of opinions, but not the initial prevalence of hypocrisy, predicts the mean consensus time and determines the opinions’ probabilities of winning.

The concealed voter model (CVM) is an extension of the original voter model, where two different opinions compete until consensus is reached. In the CVM, agents express an opinion not only publicly,…

A model for opinion dynamics, where at each time step, randomly selected agents see their opinions evolve depending on a local interaction function, and it is shown that total consensus and total polarization are the only two possible limiting configurations.

A heterogeneous mean-field theory that agrees well with the Monte Carlo simulations is presented that implies that quantitative predictions about the consensus are possible even if empirical data do not allow a complete reconstruction of all edges in the network.

The conditions under which a population of agents can ultimately reach a consensus for the truth, reach aensus for falsehood, or reach an impasse where an agent tends to adopt the opinion that is in internal concords with its innate preference are determined.

### Is the Voter Model a model for voters?

- EconomicsPhysical review letters
- 2014

A noisy voter model (accounting for social influence) with recurrent mobility of agents (as a proxy for social context) with spatial and population diversity are taken as inputs to the model, which shows that the dynamics can be described as a noisy diffusive process that contains the proper anisotropic coupling topology given by population and mobility heterogeneity.

This work proposes a computational method that uses pinning control strategy to maximize the share of a party in a social network of independent voters and shows that controlling hubs is generally a good strategy, but the optimized strategy is even better.
