In this paper, we present an experiment-based design to examine the dynamics of group decision making. The experiment-based design on group decision making that we put forth provides a path for understanding collective decision making. Understanding more about the dynamics of collective decision making will benefit public policy making and design of roundtable discussions, which can enhance communication and cooperation on important issues such as the design and placement of transportation infrastructure, hospitals facilities, and housing for the homeless, and many others.
