We study an opinion formation model that takes into account that individuals have diversepreferences when adopting an opinion regarding a particular issue. We show that the system exhibits"diversity-induced resonance" [C.J. Tessone et al. Phys. Rev. Lett. 97, 194101 (2006)], by which an externalinfluence (for example advertising, or fashion trends) is better followed by populations having the rightdegree of diversity in their preferences, rather than others where the individuals are identical or have toodifferent preferences. We support our findings by numerical simulations of the model in different networktopologies and a mean-field type analytical theory.
