A panel study following a terrorist attack in central Stockholm surveyed over 20,000 Swedes. 📍 Context: The attack occurred shortly before one survey point.
🔍 Method & Findings:
Using matching techniques and exploiting random variation, the researchers assessed how personal proximity affected Swedish public opinion.
- Those close to the attack felt more personally impacted (vividness effect). 😱
- However, they found no evidence of stronger political rally effects. 🗳️
- No increased outgroup dislike or preference for security policies was observed among them. 🛡️
🤔 Contradiction & Broader Impact:
The results challenge prior theories suggesting vivid events amplify public opinion shifts.
✅ But they align with previous research showing that terrorism does influence Swedish public opinion, regardless of geographic location within the country.
🌍 Geographic Note: The findings indicate uniform opinion changes across Sweden post-attack.
