Accidental Politicians: How Randomly Selected Legislators Can Improve Parliament Efficiency

by A. Pluchino, C. Garofalo, A. Rapisarda, S. Spagano, M. Caserta

We study a prototypical model of a Parliament with two Parties or two Political Coalitions and we show how the introduction of a variable percentage of randomly selected independent legislators can increase the global efficiency of a Legislature, in terms of both number of laws passed and average social welfare obtained. We also analytically find an “efficiency golden rule” which allows to fix the optimal number of legislators to be selected at random after that regular elections have established the relative proportion of the two Parties or Coalitions. These results are in line with both the ancient Greek democratic system and the recent discovery that the adoption of random strategies can improve the efficiency of hierarchical organizations.
