Cognitive Science: "Martin Luther Rewired Your Brain—How mass literacy, spurred by Protestantism, reconfigured our neural pathways."

Yeah, he also had a thing with farts and didn't much care for derivatives either.

I should probably do a post about the latter.

From Nautil.us:

How mass literacy, spurred by Protestantism, reconfigured our neural pathways. 

Your brain has been altered, neurologically rewired as you acquired a particular skill. This renovation has left you with a specialized area in your left ventral occipital temporal region, shifted facial recognition into your right hemisphere, reduced your inclination toward holistic visual processing, increased your verbal memory, and thickened your corpus callosum, which is the information highway that connects the left and right hemispheres of your brain.

What accounts for these neurological and psychological changes?

You are likely highly literate. As you learned to read, probably as a child, your brain reorganized itself to better accommodate your efforts, which had both functional and inadvertent consequences for your mind.

So, to account for these changes to your brain—e.g, your thicker corpus callosum and poorer facial recognition—we need to ask when and why did parents, communities, and governments come to see it as necessary for everyone to learn to read. Here, a puzzle about neuroscience and cognition turns into a historical question.

Of course, writing systems are thousands of years old, found in ancient Sumer, China, and Egypt, but in most literate societies only a small fraction of people ever learned to read, rarely more than 10 percent. So, when did people decide that everyone should learn to read? Maybe it came with the rapid economic growth of the 19th century? Or, surely, the intelligentsia of the 18-century Enlightenment, imbued with reason and rationality, figured it out?

No, it was a religious mutation in the 16th century. After bubbling up periodically in prior centuries, the belief that every person should read and interpret the Bible for themselves began to rapidly diffuse across Europe with the eruption of the Protestant Reformation, marked in 1517 by Martin Luther’s delivery of his famous 95 theses. Protestants came to believe that both boys and girls had to study the Bible for themselves to better know their God. In the wake of the spread of Protestantism, the literacy rates in the newly reforming populations in Britain, Sweden, and the Netherlands surged past more cosmopolitan places like Italy and France. Motivated by eternal salvation, parents and leaders made sure the children learned to read.

Culture tinkers with and calibrates the machinery of our minds.

The sharpest test of this idea comes from work in economics, led by Sascha Becker and Ludger Woessmann. The historical record, including Luther’s own descriptions, suggest that within the German context, Protestantism diffused out from Luther’s base in Wittenberg (Saxony). Using data on literacy and schooling rates in 19th-century Prussia, Becker and Woessmann first show that counties with more Protestants (relative to Catholics) had higher rates of both literacy and schooling. So, there’s a correlation. Then, taking advantage of the historical diffusion from Wittenberg, they show that for every 100 kilometers traveled from Wittenberg, the percentage of Protestants in a county dropped by 10 percent. Then, with a little statistical razzle-dazzle, this patterning allows them to extract the slice of the variation in Protestantism that was, in a sense, caused by the Reformation’s ripples as they spread outward from the epicenter in Wittenberg. Finally, they show that having more Protestants does indeed cause higher rates of literacy and schooling. All-Protestant counties had literacy rates nearly 20 percentage points higher than all-Catholic counties. Subsequent work focusing on the Swiss Reformation, where the epicenters were Zurich and Geneva, reveals strikingly similar patterns....

All of which led, 250 years later, to one of Fragonard's better paintings:

Oh, and it led to other stuff too.
