Since the 1960s, Democrats and Republicans in U.S. Congress have taken increasingly polarized positions, while the public's policy positions have remained centrist and moderate. We explain this apparent contradiction by developing a dynamical model that predicts ideological positions of political parties.

Aligning Political Options and Aggregated Personal Opinions on the Issues
Much work has been done in studying how to aggregate voter opinions to decide a fair election. These models presuppose that each voter has a solid understanding of their choices and can express thatExpand
Human social sensing is an untapped resource for computational social science.
It is argued that, through the lens of computational social science, this ability to 'sense' the social environment and thereby to understand the thoughts and actions of others can be used to advance research into human sociality. Expand
Preventing Extreme Polarization of Political Attitudes
An agent-based model of ideological polarization is presented that differentiates between the tendency for two actors to interact and how they respond when interactions occur, positing that interaction between similar actors reduces their difference while interaction between dissimilar actors increases their difference.

The Polarization of American Politics
Elected officials in the United States appear to represent relatively extreme support coalitions rather than the interests of middle-of-the-road voters. This contention is supported by analysis ofExpand

As Washington elites drifted toward ideological poles over the past few decades, did ordinary Americans follow their lead? In "The Partisan Sort", Matthew Levendusky reveals that we have responded toExpand
Partisans without Constraint: Political Polarization and Trends in American Public Opinion.
The findings suggest that opinion changes correspond more to a resorting of party labels among voters than to greater constraint on issue attitudes: since parties are more polarized, they are now better at sorting individuals along ideological lines. Expand
A Disconnect in Representation? Comparison of Trends in Congressional and Public Polarization
While it is widely agreed that Congress has polarized over the past 40 years, there is considerable disagreement about the extent of public polarization and its connection to congressionalExpand
Political Polarization in the American Public
For more than two decades political scientists have discussed rising elite polarization in the United States, but the study of mass polarization did not receive comparable attention until fairlyExpand
The Rise of Partisanship and Super-Cooperators in the U.S. House of Representatives
It is found 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.

Review Article: Putting Polarization in Perspective
Scholarly research has demonstrated rather conclusively that American political elites have undergone a marked partisan polarization over the past thirty years. There is less agreement, however, asExpand
The evolution of polarization in the legislative branch of government
A formal model for competitive dynamics to quantify the evolution of polarization patterns in the legislative branch of the US government is introduced, enabling it to successfully predict the direction of polarization changes in 28 out of 30 US Congresses elected in the past six decades. Expand
The Electoral Costs of Party Loyalty in Congress
To what extent is party loyalty a liability for incumbent legislators? Past research on legislative voting and elections suggests that voters punish members who are ideologically “out of step” withExpand
Polarized America: The Dance of Ideology and Unequal Riches
The idea of America as politically polarized—that there is an unbridgeable divide between right and left, red and blue states—has become a cliche. What commentators miss, however, is that increasingExpand
