From Individual Decisions to Collective Decisions Changing the World

Decision making plays an important role in many situations. This applies both to individual decision making and collective decision making, although the scope of the consequences of a decision may be quite different for both cases. In the collective case a worldwide scale can be reached whereas in an individual situation often the scale is limited to personal life. Nevertheless, also collective decisions usually have a basis in decisions of individuals within a population. In this paper it is discussed how in certain cases individual decisions can indeed lead to collective decisions with a worldwide scope of consequences. Two mechanisms for this are considered in particular: influencer-driven social contagion within social networks and plasticity-driven evolution within biological populations.


  • Collective decision
  • Contagion
  • Influencer
