    "abstract": "We here propose a model to simulate the process of opinion formation, which\naccounts for the mutual affinity between interacting agents. Opinion and\naffinity evolve self-consistently, manifesting a highly non trivial interplay.\nA continuous transition is found between single and multiple opinion states.\nFractal dimension and signature of critical behaviour are also reported. A rich\nphenomenology is presented and discussed with reference to corresponding\npsychological implications.",
