Steve Sailer recently pointed out that millennials are a lot shier about nudity than their parents and grandparents.
There are plenty of cultural explanations – less exposure to the military, more spacious accomodations, millennial whininess, etc. – but I get the impression that, as with Chinese underperformance in football, the inventor of HBD might have needlessly shied away from his own trademark framework.
- Religiosity is heritable.
- The religious have been having more surviving kids for more than a century.
- Religiosity is also correlated with modesty and aversion to nudity.
“Sexual Freedom League” protest in Berkeley, 1965. But of greater longterm relevance – what were their completed fertility rates? Berkeley has one of the lowest fertility rates in all California – lower than in crowded, uber-expensive SF. Berkeley student hippies??
In the culture wars of the past half century, many very good – or at least convincing – arguments have been brought in support of LGBT rights, personal sexual autonomy, and even atheism. Those arguments have objectively worked, at least in the sense that all of these positions have gained converts. In the case of homosexuality, we have gone from a situation where almost everyone regarded it as a criminal abnormality to one where a majority now supports gay marriage.
On the other hand, no particularly intelligent or influential voices have been arguing for the social justice virtues of nudity. With no countervailing cultural “push,” attitudes towards nudity are perhaps just going where they logically should, as the Germanic ancestry share of the US population declines, and those who remain become more religious (only genotypically, since Dawkins & Hitchens suppress their expression) with every generation.
More generally, one frequent observation is that the people at the front of social progressivism today, the SJWs, are puritans, in contrast to the 1960s hippies, who were libertines. Could this be the religious genes making themselves felt, even if in this very distorted form?
