📊 Our findings:
Counties with more bans =
⬆️ More protests
⬆️ More support for the Greens
⬆️ Long-term shift in political alignment
Democratic repression didn't kill dissent. It helped organize it.

🧪 We built a unique dataset based on archival work:
✅ 1,095 individuals banned
✅ Local protest data
✅ Voting data over decades
✅ Survey evidence
Across multiple sources and levels of analysis, one pattern stands out: backlash.

⚠️ In 1972, West Germany adopted the "Anti-Radical Decree" 🧾
The goal: keep suspected left-wing extremists out of public jobs — especially teachers.
Result? Over 1,000 people were banned. Millions were screened.
But that's not the full story...

Can banning political ideologies protect democracy? 🛡️🆚🗣️
Our (w. @valentimvicente.bsky.social) paper finds: punishing individuals might backfire. We study a West German policy banning "extreme left" individuals from working for the state.

What’s going on? 🔍
We think protest acts as a cue that mobilizes latent supporters.
It reminds them the fight for the cause is ongoing and active.
This makes support feel more urgent, visible, and worthwhile.

💸 Behavior changed.
Those who saw the protest were significantly more likely to donate money to environmental causes.
📬 There is no effect on newsletter subscription.
TL;DR: Protest might move wallets, seldomly minds.

What did we do? 🔬
We randomly assigned people walking through Berlin to either pass an FFF protest (treatment) or not (control).
Everyone filled out a pre- and post-survey. Participants were offered a chance to donate part of their compensation to climate causes and sign up for newsletters.

Can protests move bystanders, people who observe protests without being part of the march?
We conducted a 3-wave field experiment during real Fridays for Future (FFF) protests in Berlin.
