Abstract

This paper proposes a central idea in the investigation on the diffusion of influentials - that a minority of individuals influences an exceptional number of pairs is important for the formation of the public opinion. We examine this idea denominated by Watts- Salganik-Dodds: “influence hypotheses”, which use their experiments in computer simulation on processes of interpersonal influence. The intellectual work of Herbert Simon on Bounded Rationality also studied. In a majority of cases the conditions offer large cascades of opinion that are not derived from the individual influence, but by a critical mass of influential leaders. Although these results not exclude the possibility that this influence is important, suggests it influence hypothesis requires one more amore careful and resisted specification with empirical applications.
