People can simply be good at something. Maybe lesbian firefighters actually work very hard to overcome the expectations against them.
The connection of Nobel prize to race/ethnicity, as well as a claim that jews are supposedly smarter than everybody else (to the extent of dominating nobel nominations) is incredibly racist and is false.
Its basically the same ubermensch/untermensch argument made by adolf hitler in Mein Kampf about "superior Aryan race" but this time applied to jews as ubermensch. https://pmc.ncbi.nlm.nih.gov/articles/PMC3190562/
And similarly we have no evidence that lesbian firefighters who gain leadership positions got there through either genetic predisposition or bias. Maybe they just had the right attitude and the right mentors, like those researchers.
No, because Ashkenazi Jews have been demonstrated to perform significantly better on IQ tests on average, and performance on IQ tests is associated with various intellectual outcomes like winning the Nobel Prize. On the other hand, lesbians haven't been demonstrated to perform better on any kind of metrics associated with success at firefighting, and the greater difficulty women face gaining muscle mass puts them at a disadvantage.
Rabbinal Judaism has existed for nearly 2000 years, and prizes debate and logical examination.
Jewish people, particularly those that left the Middle East during diaspora, tend to have high IQ when measured, and tend not to marry outside their group. The brain is not special and different groups people differ in that organ the same way different groups differ in their muscles and blood.
Finally and quite sadly many Jewish people have been targeted viciously by individuals and governments and invading systematic execution requires a certain degree of wits.
Or that IQ tests predict physics Nobels?
My lord…
