据广泛报道，美国国会的党派之争达到了历史最高点。鉴于个人被说服遵循党的路线，同时有机会和激励与对方的成员合作，我们的目标是衡量立法者倾向于形成意识形态与对方的成员的关系的程度。我们量化了1949年至2012年美国众议院民主党和共和党成员之间的合作水平。我们定义了一个由500多万对代表组成的网络，并比较了两种不同类型的代表对在立法决定上的相互同意率：来自同一政党的代表对和来自不同政党的代表对。我们发现，尽管有短期波动，但美国国会中的党派偏见或不合作在60多年来一直呈指数级增长，没有减弱或逆转的迹象。然而，一群代表继续跨党派合作，尽管越来越多的党派。
It is widely reported that partisanship in the United States Congress is at an historic high. Given that individuals are persuaded to follow party lines while having the opportunity and incentives to collaborate with members of the opposite party, our goal is to measure the extent to which legislators tend to form ideological relationships with members of the opposite party. We quantify the level of cooperation, or lack thereof, between Democrat and Republican Party members in the U.S. House of Representatives from 1949–2012. We define a network of over 5 million pairs of representatives, and compare the mutual agreement rates on legislative decisions between two distinct types of pairs: those from the same party and those formed of members from different parties. We find that despite short-term fluctuations, partisanship or non-cooperation in the U.S. Congress has been increasing exponentially for over 60 years with no sign of abating or reversing. Yet, a group of representatives continue to cooperate across party lines despite growing partisanship.
