The three economists who authored the new RFBerlin study did not set out to bury Max Weber. But their work may end up doing just that. Weber’s century-old thesis, which credited Protestantism’s economic edge to a unique “Protestant work ethic,” has long been a pillar of sociological thought.
The new research, published in May, does not deny that Protestant regions grew wealthier. It just gives a different reason: schools, not souls.
The study, a review of existing evidence by Professors Sascha Becker, Jared Rubin, and Ludger Woessmann, points to Martin Luther’s push for universal Bible-reading. That push led to schools. By the 19th century, Protestant areas of Prussia had far higher literacy rates than Catholic ones.
That literacy advantage, the researchers argue, is what drove stronger economic development. The mechanism is concrete — more educated workers, more innovation — not a vague cultural disposition toward hard work.
This matters beyond academic squabbling. If the economists are right, then the real engine of growth in Protestant Europe was an institutional choice, not a spiritual one. Governments that want to spur development today cannot simply wait for a religious reformation.
They can, however, build schools. The study suggests that religion’s economic role is less about belief and more about the rules and norms religions help create. “Religion affects economic growth not just through individual beliefs, but by shaping the fundamental institutions and norms that govern society,” the study says.
That line has practical teeth. Consider the study’s broader argument: religion has shaped financial systems, family size, and political institutions.
Each of those channels has direct economic consequences. A religion that encourages large families may strain resources. One that prohibits certain financial instruments may stifle credit markets.
One that allies with political power may entrench corruption or, alternatively, enforce property rights. The new research treats religion as a variable in the institutional matrix, not as background noise.
The consequences for development policy are uncomfortable. Many economists prefer to focus on clean, measurable inputs: capital, technology, labor. Religion is messy.
It resists easy quantification. But the RFBerlin study implies that ignoring it means missing a major driver of how societies organize themselves. A development plan that overlooks religious institutions is building on incomplete data.
What to watch next. The study is a review, not a single new data set.
That means its conclusions will need testing against specific cases. Expect follow-up research that tries to isolate the educational channel from the work-ethic channel. Expect debates over whether the Protestant effect holds in non-European contexts.
And expect pushback from economists who prefer simpler models. For now, the study shifts the burden of proof.
Anyone who wants to cite Weber’s Protestant work ethic as an explanation for economic success now has to answer a question: Was it really the work ethic, or was it the literacy rate? The new research bets on literacy. That is a bet with policy implications.
You can build schools faster than you can change a culture.
