Throughout our whole life our memory banks store our unique emotional reactions to situations. Outcomes are marked negative or positive. Thus when it is time to make a decision, the greatest multitude of possibilities are automatically ruled out by our brain because we have established bad feelings about them. Therefore we only have to decide from a limited number of choices that our brain presents to us.

People who have severe tissue damage, and can feel no emotion about things can make no judgment between two things. They are physically incapable of limiting their choice of possibilities and so they end up choice-less.
