Replication Data for: Paranoid styles and innumeracy: Implications of a conspiracy mindset on Europeans’ misperceptions about immigrants

Innumeracy, that is, the inability to deal with numbers and provide correct estimates about political issues, is reported to be widespread among the public. Yet, despite the recognition that a conspiracy mindset is an increasingly common phenomenon in Western democracies, this has not been considered as a potential correlate of innumeracy. Using data from an online sample of respondents across ten European countries, we show that those with a higher propensity to hold a conspiracy worldview tend to overestimate the actual share of the immigrant population living in their own country. This association holds true when accounting for country heterogeneity and other cognitive, affective and socio-demographic factors. Employing a comparative design and refined measurements, the article contributes to our understanding of how a conspiracy mentality may influence perceptions of relevant political facts, questioning basic processes of democratic accountability.数盲（innumeracy），即无法处理数字信息并对政治议题做出准确估算，据报道在普通大众中广泛存在。然而，尽管学界已认识到阴谋论思维（conspiracy mindset）在西方民主国家中愈发普遍，但这一现象尚未被视为数盲的潜在关联变量。本研究使用覆盖欧洲10个国家的线上受访者样本数据，结果表明，持有阴谋论世界观倾向越高的个体，往往会高估本国居住的移民人口实际占比。在控制国家异质性以及其他认知、情感与社会人口学因素的情况下，这一关联依然成立。本研究采用比较研究设计与精细化测量手段，有助于深化我们对阴谋论心智（conspiracy mentality）如何影响个体对相关政治事实的认知的理解，并对民主问责的基本流程提出了质疑。
