“In short, high sensitivity, or responsivity, as these biologists also called it, involves paying more attention to details than others do, then using that knowledge to make better predictions in the future. Sometimes you are better off doing so; other times it is a waste of energy or worse. What if events now have nothing to do with your past experiences? Suppose you are at the horse races and the first two races are won by horses with jockeys wearing red silks. Of course you are one of the few to notice. Would you bet on red silks in the third race or, if that fails, do it in the fourth? Your subtle red-silk strategy could be a costly mistake. Further, when a past experience was very bad, an HSP can overgeneralize and avoid or feel anxious in too many situations, just because the new ones resemble in some small way the past bad one. The biggest cost to us of being highly sensitive, however, is that our nervous systems can only take in so much. Everyone has a limit as to how much information or stimulation can be absorbed before one becomes overloaded, overstimulated, over-aroused, overwhelmed, and just over! We simply reach that point sooner than others.”
