In the 1960s, and experiment was done with mice, giving them a mouse utopia. All the food they needed, housing they needed, etc. It didn't go as thought.

The parallels are apparent today, with younger people avoiding sex, violence increasing, parenthood waning, deviance on the rise, etc. It is not just an interesting article, but a sign of the e hell we are headed into.

Quote:

Eventually other deviant behavior emerged. Mice who had been raised improperly or kicked out of the nest early often failed to develop healthy social bonds, and therefore struggled in adulthood with social interactions. Maladjusted females began isolating themselves like hermits in empty apartmentsunusual behavior among mice. Maladjusted males, meanwhile, took to grooming all daypreening and licking themselves hour after hour. Calhoun called them "the beautiful ones." And yet, even while obsessing over their appearance, these males had zero interest in courting females, zero interest in sex.

More recently scholars saw similarities to the Industrial Revolution and the rise of modern urban society. The 19th and 20th centuries saw population booms across the world, largely due to drops in infant mortalitysimilar to what the mice experienced. Recently, however, human birth rates have dropped sharply in many developed countriesoften below replacement levelsand young people in those places have reportedly lost interest in sex. The parallels to Universe 25 seem spooky.
