I thought I was being clear. Access to education, which is a function of wealth, race segregation, and/or cultural expectations, or in other words, economic + social factors.

For example, if a family encourages their child to work from the earliest allowed age at the expense of schooling, that's a manifestation of both economic and social pressures.

Education? Or more directly, socio-economics.

The many of the subjects tested never had any experience with this kind of formal testing, had little to no education, and of course predictably failed on several abstract tasks. It might be that the very pattern of sitting down and intensely focusing on apparently meaningless problems isn't as innate as expected.

Religion isn’t ethnicity. Did England become less British after Catholics fell from a vast majority to ~10% post-Reformation?

And the actual numbers still don’t show a majority shift. Even if every Muslim in France kept their religion, they’d be ~10% of the population — far from "replacement".

You quoted the number but skipped the part where MacKellar says the whole premise relies on treating 3rd- and 4th-generation citizens as “not French.”

> While the ethnic demography of France has shifted as a result of post-WWII immigration, scholars have generally dismissed the claims of a "great replacement" as being rooted in an exaggeration of immigration statistics and unscientific, racially prejudiced views.[12] Geographer Landis MacKellar criticized Camus's thesis for assuming "that third- and fourth- generation 'immigrants' are somehow not French."[63] Researchers have variously estimated the Muslim population of France at between 8.8% and 12.5% in 2017, and less than 1% in 2001,[64][65] making a "replacement" unlikely according to MacKellar.[63]

Does your hospital kill more people than it saves? If so, you might be describing the 19th century Vienna General Hospital, which had two maternal wards: one staffed by trained physicians, suffering up to 30% mortality, the other by midwives, only experiencing 2~10% rates. The difference was so pronounced, local women desperately avoided the first ward, begging to give birth in the streets rather than be admitted there. Ignaz Semmelweis later attributed the disparity to doctors having performed autopsies before attending births without disinfecting their clothes, hands, or tools, dropping to only a few percent with disinfection.

Or if you limit your demographics, perhaps you might be thinking of the Tuskegee syphilis study, where treatment was intentionally withheld for a progressive, life-threatening disease without the consent of the patients, making its purpose to slowly kill the participants by its own admission?

Yes, if your hospital does seem to kill more people than most and there's no alternative explanation like accepting more severe cases, then its purpose might be inverse or orthogonal to its stated goal.
