We study how the presence of individuals with strong opinions affects a square lattice majority-vote model with noise. In a square lattice network we perform Monte-Carlo simulations and replace regular actors sigma with strong actors mu in a random distribution. We find that the value of the critical noise parameter q(c) is a decreasing function of the concentration r of strong actors in the social interaction network. We calculate the critical exponents ss/nu, gamma/nu, and 1/nu and find that the presence of strong actors does not change the Ising universality class of the isotropic majority-vote model.
