Recent studies have used expert surveys to map cross-national party ideologies into a common space.
This paper compares two bridging methods: fictional vignettes and direct assessments by U.S.-based scholars familiar with European politics.
Methodology Comparison:
- Anchoring Vignette Approach (using hypothetical scenarios)
- Direct Expert Placement Method (by transatlantic scholars)
Key Findings:
- Cross-national data shows mixed convergence/divergence patterns.
- Distinct parallels emerge on international economic integration issues.
These findings suggest expert-based methods can effectively overcome the challenge of comparing political systems across different regions.
