许多观察家在没有证据的情况下断言。美国人的社会观点已经两极分化。作者利用20多年来定期重复的一般社会调查和全国选举调查社会态度项目，提出了以下问题：（1）美国人的意见是否变得更加分散（方差更高）？(2)分布是否变得更平坦或更双峰（峰度下降）？(3)意见是否在意见领域内和意见领域之间变得更加受到意识形态的限制？(4)配对的社会群体在他们的观点上变得更加不同了吗？作者在过去二十年中几乎没有发现两极分化的证据，对堕胎的态度以及共和党和民主党之间的意见分歧是例外情况。
Many observers have asserted with little evidence that. Americans' social opinions have become polarized. Using General Social Survey and National Election Survey social attitude items that have been repeated regularly over 20 years, the authors ask (1) Have Americans' opinions become more dispersed (higher variance)? (2) Have distributions become flatter or more bimodal (declining kurtosis)? (3) Have opinions become more ideologically constrained within and across opinion domains? (4) Have paired social groups become more different in their opinions? The authors find little evidence of polarization over the past two decades, with attitudes toward abortion and opinion differences between Republican and Democratic party identifiers the exceptional cases.
