Veiled Power: How Rosenwald Teachers Quietly Shaped
the Civil Rights Movement

Omar Wasow∗ Jacob M. Grumbach∗

April 1, 2026

Abstract
What precipitates the collapse of seemingly durable social orders like Jim Crow? During the 1920s, approximately 5,000 “Rosenwald Schools” were built across the rural South through a partnership between philanthropist Julius Rosenwald and Black communities who raised matching funds, donated land, and petitioned local governments. Local elites saw vocational training that would preserve the racial order. We argue Black educators used this accommodationist cover to build veiled capacity: organizational infrastructure for collective action behind a veil
of compliance. Counties with more Rosenwald Schools show greater civil rights protest in the 1960s. Mediation analysis reveals that pre-existing social capital predicted protest through Rosenwald teacher placements, not enrollment. Instrumental variable models suggest the effect is not driven by community selection. Moving from no Rosenwald teachers to the 75th percentile predicts 45% more protest. The political effects of education may depend less on what elites intend than on what educators build where elites cannot see.

Excited to share new paper w/ @jakemgrumbach.bsky.social: "Veiled Power: How Rosenwald Teachers Quietly Shaped the Civil Rights Movement"

The puzzle: did ~5,000 segregated schools built in rural South emphasizing “manual labor” strengthen or weaken Jim Crow? 🧵 omarwasow.com/wasow_grumba...

Does being high-skilled protect you from ethnic bias when applying for a UK visa? In a new pre-registered experiment to be published in International Migration Review, I find that high occupational status doesn't shield immigrants from ethnic prejudice — it may activate it.

La transición climática y energética depende menos del tipo de régimen que de la fortaleza institucional: capacidad estatal, estabilidad regulatoria y credibilidad para sostener compromisos y generar confianza.

The political effects of X's feed algorithm

Feed algorithms are widely suspected to influence political attitudes. However, previous evidence from switching off the algorithm on Meta platforms found no political effects'. Here we present results from a 2023 field experiment on Elon Musk's platform X shedding light on this puzzle. We assigned active US-based users randomly to either an algorithmic or a chronological feed for 7 weeks, measuring political attitudes and online behaviour. Switching from a chronological to an algorithmic feed increased engagement and shifted political opinion towards more conservative positions, particularly regarding policy priorities, perceptions of criminal investigations into Donald Trump and views on the war in Ukraine. In contrast, switching from the algorithmic to the chronological feed had no comparable effects.
Neither switching the algorithm on nor switching it off significantly affected affective polarization or self-reported partisanship. To investigate the mechanism, we analysed users' feed content and behaviour. We found that the algorithm promotes conservative content and demotes posts by traditional media. Exposure to algorithmic content leads users to follow conservative political activist accounts, which they continue to follow even after switching off the algorithm, helping explain the asymmetry in effects. These results suggest that initial exposure to X's algorithm has persistent effects on users' current political attitudes and account-following behaviour, even in the absence of a detectable effect on partisanship.

A new paper shows that less than 2 months of exposure to Twitter’s algorithmic feed significantly shifts people’s political views to the right.

Moving from chronological feed to the algorithmic feed also increases engagement.

This is one of the most concerning papers I’ve read in awhile.
