Clearly caused by the same (unknown) thing that's been causing the double-digit decline in testosterone levels of Western men for the last few decades, regardless of job market or dating apps or whatever. So I'm leaning toward physiological explanation, not social.
- anonytrary 8y agoI don't know either, but I would not make this guess, because cultural evolution tends to happen at a much faster pace than physiological (biological?) evolution. Physiology will not change much in 20 years, but culture could change drastically in the same timeframe.
- Mirioron 8y agoThere has been a significant population level decrease in testosterone in men. It's at around 1.2% per year when adjusted by age.[0] Similar effects have been found in other countries too. I think this is what he means when he says physiological.

- bm1362 8y agoThat study had roughly 3k participants, from the Boston area. In my opinion, the are more than probably many factors that influence testosterone production and that’s not sufficient evidence to declare a population-wide crisis.

- cousin_it 8y agoWasn't talking about evolution, was talking about stuff in the environment (food, plastics, etc) that affects physiology.
- anonytrary 8y agoReplace "evolution" with "changes". I don't necessarily mean Darwinian evolution (if that's what you thought).
- nukeop 8y agoBPA plastics? Bad diets? Roundup? Chemicals in the water that make the freaking frogs gay? It's funny until it happens to you.
