Group decision making refers to a process in which two\r\nor more individuals select one choice out of several possible ones. This species form\r\ncomplex tunnel systems underground in which different rooms are determined by\r\ngroup members. We investigated how this species decide the room allocation by\r\ncombining behavioural observation, experiments, and simulation.
