The critique of quantum mind: measurement, consciousness, delayed choice, and lost coherence

The formal logic of many celebrated paradoxes of quantum measurements does not rule out the effect of the observer's mind on the outcome of a measurement or even on the prehistory of a quantum system. The modern methodology of quantum mechanics offers a consistent explanation of the role of an observer's consciousness in physical measurements in universal terms of the interaction between a quantum system and the environment, loss of quantum coherence, and the unitary evolution of the state vector. In this picture, the observer's consciousness is no longer an agent that changes the prehistory of a quantum system, but is rather a subject of physical study. Instruments and methods based on quantum physics open a new phase in such studies.
