| Description | German Bilendi panel respondents (April 2025, n = 3,864 in the deposit) chose between 3 pairs of hypothetical coalition agreements varying the coalition, economic policy, protectionism (tariffs, green tariffs or EU-contribution cuts), migration, women's quotas, LGBT funding and social-media regulation; outcomes are the preferred agreement and a 1-5 likelihood rating of each. |
