摘要:

当与意识形态没有实质性关系的活动在政治上结盟和两极分化时,生活方式政治就出现了。同质性和社会影响能够自己产生这些断层线;然而,来自人口统计的社会身份可能作为协调机制,通过这种机制,生活方式政治被动员起来并传播开来。使用来自不同种族/民族,教育,年龄,性别和收入人口统计数据的用户的299,327个Facebook兴趣的137,661,886个观察数据集,我们发现生活方式政治的最极端实例是那些高度混淆的人口统计数据,如种族/民族(例如,黑人艺术家和表演者)。在调整人口影响的政治结盟后,生活方式政治向政治“中心”下降了27.36%,人口混淆的利益不再是最两极分化的利益。相反,在人口统计学解构之后,我们发现最自由的利益包括电动汽车,计划生育和自由派讽刺,而最保守的利益包括共和党和保守派评论员。我们使用综合社会调查验证了我们对政治联盟和生活方式政治的衡量,并发现在Facebook等社交媒体无处不在之前,生活方式政治存在类似的人口纠缠,这让我们有信心我们的结果不是由于回音室或过滤气泡。同样,由于人口特征存在于意识形态价值观之前,我们认为,我们观察到的人口混淆是我们在聚集的利益中发现的极端生活方式政治的因果关系。最后,我们将我们的研究结果与辛普森悖论,文化杂食性和网络自相关。

英文摘要:

Lifestyle politics emerge when activities that have no substantive relevance to ideology become politically aligned and polarized. Homophily and social influence are able generate these fault lines on their own; however, social identities from demographics may serve as coordinating mechanisms through which lifestyle politics are mobilized are spread. Using a dataset of 137,661,886 observations from 299,327 Facebook interests aggregated across users of different racial/ethnic, education, age, gender, and income demographics, we find that the most extreme instances of lifestyle politics are those which are highly confounded by demographics such as race/ethnicity (e.g., Black artists and performers). After adjusting political alignment for demographic effects, lifestyle politics decreased by 27.36% toward the political "center" and demographically confounded interests were no longer among the most polarized interests. Instead, after demographic deconfounding, we found that the most liberal interests included electric cars, Planned Parenthood, and liberal satire while the most conservative interests included the Republican Party and conservative commentators. We validate our measures of political alignment and lifestyle politics using the General Social Survey and find similar demographic entanglements with lifestyle politics existed before social media such as Facebook were ubiquitous, giving us strong confidence that our results are not due to echo chambers or filter bubbles. Likewise, since demographic characteristics exist prior to ideological values, we argue that the demographic confounding we observe is causally responsible for the extreme instances of lifestyle politics that we find among the aggregated interests. We conclude our paper by relating our results to Simpson's paradox, cultural omnivorousness, and network autocorrelation.
