Pornography, sperm competition, and behavioural ecology
By Michael N. Pham, William F. McKibbin, and Todd K. Shackelford
Like candy, pornography creates an adaptive mismatch. For a moment, try to see the world not from “human eyes” but from the eyes of an animal biologist. You might think that men’s enjoyment of pornography is bizarre: men are sexually aroused by the sight of ink that’s splattered on magazine pages, or computer pixels that display light. Nobody would argue that men evolved to have sex with magazines or computers. Adaptive mismatch? Quite.
