11/
🎯 The takeaway:
States use surveillance as a preventive tool against the empowerment of educated but excluded groups.

👉 As excluded groups gain political empowerment, surveillance may reproduce inequalities by silencing them exactly as they gain political voice.

10/ Across democracy and dictatorship, and with more and less technology to collect data, the logic of surveillance was similar:

States target those combining political capacity (education) with radical grievances (subalternity).

9/ ➡️ Result 3:

Across 5 indicators of political activism—voting, protests, strikes, holding political roles, and armed resistance—educated cohorts did not become more engaged.

Surveillance expanded preventively, not in reaction to mobilization.

8/ ➡️ Result 2:
Who faced the brunt of surveillance? The working class. The newly educated poor were watched longer, more harshly, and more intensively, consistently with the state fearing their empowerment.

7/ The effect persists even when individuals move elsewhere, in line with surveillance following a portable asset (education) rather than municipal-level changes.

6/ We present 3 results:

➡️ Result 1:

Municipality-cohorts exposed to more schooling were 64% more likely to be surveilled.

The effect increases as the state expands education and disappears when later reforms equalize schooling across municipalities.

5/ 🎲 The shock:

The Casati Law mandated primary schooling for 2 years everywhere but extended it for +2 years in towns >4,000 inhabitants and cohorts born post 1854.

We show the reform reduced illiteracy and use it in a difference-in-discontinuity design by population and cohort.

4/ 📃 📄 Descriptively, educated people were more likely to be watched. But education may proxy for background, status, or other fixed attributes.

We need a shock to education that affects otherwise similar people.

3/ Unsupervised LLM on 1,200+ police files shows that mobilization capacity – and a particular marker of it, education, – together with potential for subversion are recurring traits noted by the surveillance state. 📚

2/ 💡 We propose that states strategically target those combining capacity to mobilize with grievances for radical mobilization – educated but subaltern individuals perceived as most threatening to state stability.

This idea is rooted in descriptive data:

🚨 New WP 🚨:

All states monitor the political activity of their citizens. But who do they choose to surveil, and why?

We study this question with the universe of Italian political surveillance files: 152,000 individuals born 1816–1932, across democracy and autocracy.
