https://phys.org/news/2021-06-quarter-adults-dont-childrenand-theyre.html This is the first study of this kind that I've come across, which all but blatantly calls the previous studies garbage. Over the last century, the statistical evidence has been steadily building both physically and sociologically that reality doesn't even vaguely resemble Western culture, and that metaethics rule the universe, but the evidence has largely been suppressed and, only now, is the truth beginning to come out. The workaholic Japanese and white US and EU populations have been imploding faster than any other on the planet for half a century, and their proud teachers can all brag that they made more money. My work entails encouraging the idiots to kill themselves faster, and reproduce even less often, if that's what get their rocks off.
