This study formulates the uncertainty relation accompanying the quantum fluctuation of the life and death drives using the two-state system quantum-mechanical mathematical model. A function hypothesis model of the intervention method with either-or questions is then developed. A drive is treated as a dynamical variable and represented as the operator of the spin components, and the mental state is represented as the quantum-mechanical state vector. The psychological model can be expressed through such a correspondence as a quantum mathematical model. In this way, we can quantitatively discuss the transition probabilities and the uncertainty relations in the psychological model. The either-or questions function to assist the energy processing of the internal drive through the fixation of position enabled by the resonance of position and drive. The assignment of words to particles of the opposite vector enables the formulation of questions probing 50% probability. A processing can therefore be expected through the uncertainty relationships between the life and death drives. This mathematical model benefits the literature by creating a starting point for the differentiation and integration of the two drives in a psychodynamics intervention while maintaining the perspective of economic theory. The actual measurement and examination of linking such psychodynamic interventions of either-or questions are necessary.
