We review some recent kinetic models for opinion formation. The time evolution of the opinion distribution is described by (systems of) Boltzmann-type equations. We show that at suitably large times, in presence of a large number of interactions in each of which individuals change their opinions/positions only little, the Boltzmann-type equations are well approximated by Fokker-Planck type equations, which admit different, nontrivial steady states. Furthermore, we discuss the extension towards the more general case when the opinion dynamics depends on an additional independent variable, e.g. an assertiveness or spatial variable.
