    "abstract": "We introduce stochastic driving in the Sznajd model of opinion spreading.\nThis stochastic effect is meant to mimic a social temperature, so that agents\ncan take random decisions with a varying probability. We show that a stochastic\ndriving has a tremendous impact on the system dynamics as a whole by inducing\nan order-disorder nonequilibrium phase transition. Interestingly, under certain\nconditions, this stochastic dynamics can spontaneously lead to agents in the\nsystem who are analogous to Galam\u0027s contarians.",
