The wonderfish scenario is therefore improbable. Anchors We can overcome the above difficulty by increasing the number of subjective states that can have a direct impact on probability amplitudes. I call these states anchors . Pain is an anchor. It ties painful experience to an appropriate occasion for pain in the objective world.
Fear is another anchor.
An anchor is an experience that has an intrinsic motivational direction, thereby having a definite positive or negative effect on the probability amplitude of the component of the quantum superposition in which it occurs. Natural selection then chooses the influences that are appropriate to the survival of the species. This is how a reliable psycho-physical parallelism is established. Without anchors that can affect points of positive or negative interactive feedback between quantum mechanical and psychological states, a parallelism would be impossible. Not all conscious experiences are anchors.
