Destabilizing democracyComplex systems help explain how democracies are destabilized

Published 30 November 2018

Complex systems theory is usually used to study things like the immune system, global climate, ecosystems, transportation or communications systems. But with global politics becoming more unpredictable – highlighted by the U.K.’s vote for Brexit and the presidential elections of Donald Trump in the United States and Jair Bolsonaro in Brazil – it is being used to examine the stability of democracies. “There is little work on the circumstances under which instability of democracy might happen. So, we lack the theory to show us how a democracy destabilizes to the point it is not describable as a democracy anymore,” says a researcher.

Complex systems theory is usually used to study things like the immune system, global climate, ecosystems, transportation or communications systems.

But with global politics becoming more unpredictable – highlighted by the U.K.’s vote for Brexit and the presidential elections of Donald Trump in the United States and Jair Bolsonaro in Brazil – it is being used to examine the stability of democracies.

An international, interdisciplinary team including mathematicians, economists, psychologists, philosophers, sociologists and political scientists publishes a collective examination of the work in this field today in the European Journal of Physics.

Dr. Karoline Wiesner, from the University of Bristol’s School of Mathematics, is the lead author. She explains the premise of the team’s work: “There is little work on the circumstances under which instability of democracy might happen. So, we lack the theory to show us how a democracy destabilizes to the point it is not describable as a democracy anymore.

“This reflects the way we in the West have lived in the past fifty to sixty years. But times have changed. Citizens of democracies are becoming less content with their institutions. They are increasingly willing to ditch institutions and norms that have been central to democracy. They are more attracted to alternative, even autocratic regime types.

“Furthermore, we recently saw elected officials in Hungary and Poland put pressure on critical media and undermine institutions like independent courts. This illustrates the need to rethink the idea of democracies as stable institutions.”

Bristol says that the team’s paper focuses on two features of complex social systems in general, and of democratic systems in particular: feedback and stability, and their mutual relationship.

They examined how the stability of the social institutions democracy relies on are affected by feedback loops.

They looked at several strands, including economic inequality, political divergence, and the impact of media and social media on societal “norms.”
