We use simulations of mantle convection with surface yielding to show that multiple tectonic regimes are possible for equivalent system parameter values. Models with the same lithospheric strength parameters and the same vigor of convection can display different modes of tectonics. Within the region of multiple solutions, the evolutionary pathway of the system is the dominant factor that determines the tectonic mode (e. g., whether mantle convection operates in a plate tectonic like mode). The extent of the multiple regimes window is found to increase with the temperature-dependent viscosity contrast across the system. The implication for models that seek to predict the tectonic regimes of planets is that the temporal evolution of the planet needs to be taken into account. A further implication is that modeling studies can lead to different conclusions regarding the tectonic state of a planet, extra-solar planets in particular, despite the final model parameter values remaining equivalent.
