Negative response to an excessive bias by a mixed population of voters
We study an outcome of a vote in a population of voters exposed to an externally applied bias in favour of one of two potential candidates. The population consists of ordinary individuals, that are in majority and tend to align their opinion with the external bias, and some number of contrarians —...

irk-123456789-1569672019-06-20T01:27:02Z Negative response to an excessive bias by a mixed population of voters Dotsenko, V.S. Mejía-Monasterio, C. Oshanin, G. We study an outcome of a vote in a population of voters exposed to an externally applied bias in favour of one of two potential candidates. The population consists of ordinary individuals, that are in majority and tend to align their opinion with the external bias, and some number of contrarians — individuals who are always hostile to the bias but are not in a conflict with ordinary voters. The voters interact among themselves, all with all, trying to find an opinion reached by the community as a whole. We demonstrate that for a sufficiently weak external bias, the opinion of ordinary individuals is always decisive and the outcome of the vote is in favour of the preferential candidate. On the contrary, for an excessively strong bias, the contrarians dominate in the population’s opinion, producing overall a negative response to the imposed bias. We also show that for sufficiently strong interactions within the community, either of two subgroups can abruptly change an opinion of the other group. Ми вивчаємо результат голосування в популяцiї виборцiв, якi перебувають пiд дiєю зовнiшнього змiщення на користь одного з потенцiйних кандидатiв. Популяцiя складається зi звичайних iндивiдуумiв, якi становлять бiльшiсть i чия думка має тенденцiю до вирiвнювання пiд дiєю зовнiшнього змiщення, i з деякого числа протилежно настроєних iндивiдуумiв, якi завжди є противниками змiщення, але не знаходяться в конфлiктi з простими виборцями. Виборцi взаємодiють мiж собою як всi зi всiма, намагаючись прийти до спiльної думки спiльноти як цiлого. Ми показуємо, що для достатньо слабого зовнiшнього змiщення, думка звичайних iндивiдуумiв є завжди вирiшальною, i результат голосування є в користь преференцiйного кандидата. Навпаки, для надто сильного змiщення протилежно настроєнi iндивiдууми домiнують, приводячи вцiлому до негативного вiдгуку на прикладене змiщення. Ми також показуємо, що для достатньо сильних взаємодiй в межах спiльноти, будь-яка з двох пiдгруп може несподiвано змiнити думку iншої групи. 2017 Article Negative response to an excessive bias by a mixed population of voters / V.S.

| description |
We study an outcome of a vote in a population of voters exposed to an externally applied bias in favour of one of
two potential candidates. The population consists of ordinary individuals, that are in majority and tend to align
their opinion with the external bias, and some number of contrarians — individuals who are always hostile to
the bias but are not in a conflict with ordinary voters. The voters interact among themselves, all with all, trying to
find an opinion reached by the community as a whole. We demonstrate that for a sufficiently weak external bias,
the opinion of ordinary individuals is always decisive and the outcome of the vote is in favour of the preferential
candidate. On the contrary, for an excessively strong bias, the contrarians dominate in the population’s opinion,
producing overall a negative response to the imposed bias. We also show that for sufficiently strong interactions
within the community, either of two subgroups can abruptly change an opinion of the other group. |
