@a_centrism @AleResnik @dpinsen Reality is racist by his definition. Behold, European ancestry across the Americas, nations and some of their subnational divisions, as well as how well that area is working out as a single index score. Notice a pattern?

@a_centrism @AleResnik @dpinsen Some years later, we did a follow up study where we looked at the divisions of Argentina too. Same thing.

@a_centrism @AleResnik @dpinsen Economists have been noting the same thing for years at the world level.

Try this 2014 paper:

The European Origins of Economic Development

@a_centrism @AleResnik @dpinsen Works within the USA too, as shown in our study above (states), and also for counties. Here's a 2015 economist study:

Does It Matter Where You Came From? Ancestry Composition and Economic Performance of U.S. Counties, 1850-2010

@a_centrism @AleResnik @dpinsen Last year, I plotted data for the >5000 counties (communes?) of Brazil, using data from public test scores (ENEM) and self-reported race / "color". Notice a pattern?

@a_centrism @AleResnik @dpinsen So... is this just aggregate data? Nope, this works too if we look at individuals. Data from >8000 American kids and youths.

Here, European ancestry predicts intelligence no matter how people self-identify. It's a mystery!

(to some!)
