Replication Data for: Strange Bedfellows: The Bundestag's Free Vote on Pre-Implantation Genetic Diagnosis (PGD) Reveals How Germany's Restrictive Bioethics Legislation is Shaped by a Christian Democratic/New Left Issue-Coalition

Germany's bioethical legislation presents a puzzle: Given structural factors, the country should be at the forefront of reproductive medicine, but its embryology regime remains one of the strictest in Western Europe. Past research has linked this fact to an unusual coalition of Christian and New Left groups, which both draw a connection from modern embryology to eugenics under the Nazis. In this article, the workings of this alleged alliance are demonstrated at the micro-level for the first time. The behaviour of individual MPs in a crucial free vote on pre-implantation genetic diagnosis (PGD) is modelled using data on their political, sectoral, and religious affiliations. Identifying as a Catholic and membership in Christian organisations are strong predictors of resistance to PGD. Even more importantly, net of religious and professional ties, affiliation with \emph{either the Christian Democrats or the left-libertarian Green party} is closely linked to restrictive bioethical preferences. The modest liberalisation in 2011 was contingent on external factors and the overwhelming support of the historically unusually large FDP delegation. With the FDP no longer represented in parliament and the Christian Democratic/New Left issue coalition even stronger than before, further liberalisation is unlikely.

德国的生物伦理立法堪称一个难解之谜：从结构性因素来看，该国本应走在生殖医学领域的前沿，但其胚胎学监管制度仍是西欧最为严苛的体系之一。过往研究将这一矛盾局面与基督教与新左翼团体结成的罕见联盟联系起来——这两大阵营均将现代胚胎学与纳粹时期的优生学相挂钩。
本文首次在微观层面阐释了这一所谓联盟的运作逻辑。针对植入前胚胎遗传学诊断（pre-implantation genetic diagnosis, PGD）的关键自由投票中，议员个体的行为可通过其政治派系、行业背景与宗教归属数据进行建模分析。研究发现，天主教信徒身份以及基督教组织成员身份，是反对PGD的强预测因子。更为关键的是，在控制宗教与职业关联的干扰后，无论是隶属于基督教民主联盟，还是左翼自由派绿党，其与严苛的生物伦理政策偏好均存在显著关联。
2011年的小幅自由化改革依赖于外部因素，以及历史上规模异常庞大的自由民主党（Free Democratic Party, FDP）代表团的压倒性支持。如今自由民主党已不再拥有议会席位，且基督教民主派与新左翼的议题联盟较以往更为稳固，进一步推动自由化改革的可能性微乎其微。本数据集存档包含了用于复现《研究与政治》（Research & Politics）期刊文章中所有表格与图表的全部数据及Stata脚本。
