Basic Mechanisms for the Perfect Democratic Structure

  • Serge Galam
Part of the Understanding Complex Systems book series (UCS)


The democratic majority rule voting in democratic bottom-up hierarchical structures is shown to produce under certain conditions dictatorship effects by keeping a minority in power against a huge increase of the opposition. No coercion is necessary, only democratic voting. This result sheds new light in particular on the internal strength of former communist organizations. It also provides a scheme to assess the conditions by which a minority extremist group can quickly get into power by democratic means and without any intermediate step. In turn, it also defines the conditions by which to avoid such a danger.
