Query: Noise and disorder: phase transitions and universality in a model of
  opinion formation   In this work we study a 3-state opinion formation model considering two
distinct mechanisms, namely independence and conviction. Independence is
introduced in the model as a noise, by means of a probability of occurrence
$q$. On the other hand, conviction acts as a disorder in the system, and it is
introduced by two discrete probability distributions. We analyze the effects of
such two mechanisms on the phase transitions of the model, and we found that
the critical exponents are universal over the order-disorder frontier,
presenting the same universality class of the mean-field Ising model. In
addition, for one of the probability distributions the transition may be
eliminated for a wide range of the parameters.
