Dynamics with choice is a generalization of discrete-time dynamics where instead of the same evolution operator at every time step there is a choice of operators to transform the current state of the system. Many real-life processes studied in chemical physics, engineering, biology and medicine, from autocatalytic reaction systems to switched systems to cellular biochemical processes to malaria transmission in urban environments, exhibit the properties described by dynamics with choice. We study the long-term behaviour in dynamics with choice. We prove very general results on the existence and properties of global compact attractors in dynamics with choice. In addition, we study the dynamics with restricted choice when the allowed sequences of operators correspond to subshifts of the full shift. One of the practical consequences of our results is that when the parameters of a discrete-time system are not known exactly and/or are subject to change due to internal instability or a strategy or Nature's intervention, the long-term behaviour of the system may not be correctly described by a system with 'averaged' values for the parameters. There may be a Gestalt effect.
