While Wendt's 2015 book Quantum Mind and Social Science does not focus on political science, it does discuss the applicability of quantum theory to social systems in general, and its publication led to a great deal of analysis and discussion on this topic. Other related areas where quantum ideas are seeing applications include quantum game theory, quantum decision theory, quantum finance and quantum economics. In a 2019 article for the Bretton Woods Committee, Andrew Sheng wrote that "A quantum paradigm of finance and the economy is slowly emerging, and its nonlinear, complex nature may help the design of a future global economy and financial architecture."
