³¹Another striking example in the case of humans is pornography, where watching sexually desirable models on a computer screen is felt to be somehow rewarding by its human consumer, and leads to desire towards such pictures. Simply seeing sexually attractive people naked should indeed have a very high state-value, since that is likely to happen only when copulation is near—at least in our evolutionary past. But in the modern world, this behaviour is quite dysfunctional in the sense that there is almost no chance that the consumer would be actually able to mate with those models.
