Did Nazi marches persuade or polarize voters? In 1932 Hamburg, full exposure raised Nazi vote share by ~1 pp (18% of citywide gain), but only by widening divides: support rose in Nazi-leaning areas and fell in opposition areas. Spillovers made up ~half the effect. academic.oup.com/jeea/advance...

Abstract
Political polarization is a growing concern in many countries. Are mass protests merely a sign of increasing cleavages, or do they polarize societies? In this paper, we estimate the impact of Nazi marches in 1932 Hamburg, using granular data from 622 voting precincts during six elections.
We show propaganda can persuade—but it does so by raising the share of areas with high levels of Nazi support. Importantly, marches can also backfire, repelling voters. Thus, protest marches lead to polarization.
These effects diffused through social networks, measured using contagion patterns across neighborhoods during the 1918 Spanish flu outbreak. The electoral effects of social spillovers are similar in importance to those of direct exposure and grow over time.
(JEL: D72, D74, N44)

Figure 3. Nazi Party swing. The map shows a heatmap of the change in NSDAP vote share after the marches. The change is calculated between the two elections before the marches (13 March and 10 April 1932) and the three elections afterward (31 July 1932–5 March 1933).
Voting behavior is observed at the polling-station level. The average change in NSDAP vote share is computed using a spatial kernel with a fixed bandwidth of 500 meters around each polling station and divided into 10 equally sized groups. Darker colors indicate larger gains for the NSDAP. Black lines show the routes of the two Nazi marches in April 1932.
Sources: Voting data: Statistical Bulletin of Hamburg (Sköllin 1932a, 1932b, 1933); Nazi marches: SA Hamburg documents (State Archive Hamburg 1932a, 1932b).

Figure 5. Distribution regression of direct exposure. The figure plots the estimated effect of direct exposure to Nazi marches using the main panel of elections from 1932 and 1933 (y-axis). The dependent variable equals 1 when the NSDAP vote share exceeds the threshold shown on the x-axis. Thresholds range from the 5th to the 95th percentile of the NSDAP vote-share distribution in increments of 2 percentage points.
The vertical line marks the 29% crossing point between backlash—a negative effect of direct exposure—and persuasion—a positive effect. The p-value for backlash tests whether all exposure coefficients below the 29% threshold are jointly zero. The p-value for persuasion applies the analogous test to all coefficients above 29%.
The regressions control for polling-station and election fixed effects, street and demographic characteristics interacted with election fixed effects, and indirect exposure to the marches. Standard errors are clustered at the polling-station level. See equation (3) and the paper for details of the joint tests.

Figure 7. Indirect effect. Panel (a) plots a bin scatter of flu-based indirect exposure (x-axis) against the change in NSDAP vote share after the marches (y-axis). The change in NSDAP vote is calculated between two elections before the marches (13 March and 10 April 1932) and three elections afterward (31 July and 6 November 1932, and 5 March 1933). The t-statistic is estimated from a bivariate regression with robust standard errors. See the main text and Online Appendix for the construction of the flu-based indirect-exposure measure.
Panel (b) plots estimates of flu-based indirect exposure from equation (6), with corresponding 95% confidence intervals by election (computed from Table 4, column 5).
Sources: Nazi marches: SA Hamburg documents (State Archive Hamburg 1932a, 1932b); indirect exposure: death records (State Archive Hamburg 1917, 1918, 1919); voting data: Statistical Bulletin of Hamburg (Sköllin 1930, 1932a, 1932b, 1933).

A Demographic Theory of Similarity-Biased Social Learning. Now out in PNAS, led by the incomparable @apvelilla.bsky.social . We use modeling to explore conditions for the (cultural) evolution of parochial (and anti-parochial) learning biases. www.pnas.org/doi/10.1073/...

Humans adapt by learning from others, but risk acquiring maladaptive behaviors when learning from individuals facing different conditions. We present an evolutionary model exploring how individuals use social identity markers to select learning targets in diverse populations. Learners evolve biases that track reliable information sources: preferring similar individuals when in-group knowledge is adaptive, and dissimilar individuals when in-group behaviors are disadvantageous. Our framework demonstrates that this adaptive bias makes social learning viable even when it is costlier than individual learning. Additionally, we show that a minimum threshold of reliable cultural information is required for social learning to spread, providing a mathematical explanation for how demographic diversity drives population-level patterns of cultural segregation and assimilation.

Why do human societies adopt rigid moral rules? People often have legitimate reasons for failing to cooperate, yet those reasons are often opaque, allowing opportunists to disguise selfishness as justified hardship. Rigidity preserves cooperation when trust is fragile www.pnas.org/doi/10.1073/...

Why do societies rely on rigid moral rules? Don't lie. Keep your promises. Don't steal. We all recognize there are good reasons to make exceptions. So why are moral rules so often categorical? Our new paper proposes an answer. 🧵

Furthermore, we foundgreatest agreement in preference for adorned, ancestral, andlower-frequency sounds. humans’ music listening experiencewas associated with preferences.
