Abstract
We have recently shown that a stochastic driving in an opinion spreading model has a tremendous impact on the system dynamics, spontaneously leading to system's agents which are analogous to Galam's contrarians. We have analyzed the existence of stochastic resonance phenomena in this social model in the presence of such contrarians. We have found that the system does not show conventional stochastic resonance, but, interestingly, it does exhibit system size stochastic resonance.
