对美国日益增长的政治两极分化和反感的研究主要是研究公共机构和政治过程，而忽略了私人影响，包括紧张的家庭关系。利用匿名的智能手机位置数据和选区级投票，我们发现来自反对党选区的居民参加感恩节晚宴的时间比同党晚宴短30到50分钟。这种从平均257分钟的下降经受住了广泛的空间和人口控制。2016年，来自有大量政治广告的媒体市场的游客在感恩节晚餐上停留的时间缩短了两倍——2015年没有观察到这种效应——这意味着与选举相关的行为有关。这种影响似乎是不对称的：尽管2016年民主党选区的居民出行比2015年少，但共和党选区的居民为了应对政治分歧，缩短了感恩节晚餐的时间。在全国范围内，由于党派影响，2016年感恩节晚餐上的跨党派谈话损失了3400万小时。
Research on growing American political polarization and antipathy primarily studies public institutions and political processes, ignoring private effects, including strained family ties. Using anonymized smartphone-location data and precinct-level voting, we show that Thanksgiving dinners attended by residents from opposing-party precincts were 30 to 50 minutes shorter than same-party dinners. This decline from a mean of 257 minutes survives extensive spatial and demographic controls. Reductions in the duration of Thanksgiving dinner in 2016 tripled for travelers from media markets with heavy political advertising-an effect not observed in 2015-implying a relationship to election-related behavior. Effects appear asymmetric: Although fewer Democratic-precinct residents traveledin 2016 than in 2015, Republican-precinct residents shortened their Thanksgiving dinners by more minutes in response to political differences. Nationwide, 34 million hours of cross-partisan Thanksgiving dinner discourse were lost in 2016 owing to partisan effects.
