“Social consensus through the influence of committed minorities” (DOI: 10.1103/PhysRevE.84.011130) is a fascinating read. In it, Xie et al. of the Rensselaer Polytechnic Institute take the well-known phenomenon of an inflection point in thinking – a tipping point past which a minority opinion will become the majority opinion – and use computational and analytic simulations to try to determine what that point might be. Their conclusion? That when the number of “true believers” reaches 10% of a given population, conversion of the rest of the population becomes inevitable. Below 10%, it would take far longer for such a conversion to take place.
