Query: Spontaneous emergence of contrarian-like behaviour in an opinion
  spreading model   We introduce stochastic driving in the Sznajd model of opinion spreading.
This stochastic effect is meant to mimic a social temperature, so that agents
can take random decisions with a varying probability. We show that a stochastic
driving has a tremendous impact on the system dynamics as a whole by inducing
an order-disorder nonequilibrium phase transition. Interestingly, under certain
conditions, this stochastic dynamics can spontaneously lead to agents in the
system who are analogous to Galam's contarians.
