我们结合联合收割机九个先前提出的措施，构建一个美国成年人的政治两极分化指数。我们发现，近年来两极分化的增长最大的是最不可能使用互联网和社交媒体的人口群体。例如，我们的总体指数和九项单项指标中的八项指标显示，75岁以上的人比18-39岁的人增长更大。这些事实反驳了互联网是政治两极分化加剧的主要驱动力的假设。
We combine nine previously proposed measures to construct an index of political polarization among US adults. We find that the growth in polarization in recent years is largest for the demographic groups least likely to use the internet and social media. For example, our overall index and eight of the nine individual measures show greater increases for those older than 75 than for those aged 18–39. These facts argue against the hypothesis that the internet is a primary driver of rising political polarization.
