I view polarization as the unifying theme between my study of political behavior and political institutions. The ideological extremity of the major political parties at the mass level determines the politicians we observe at the elite level. In turn, these politicians create more or less ideologically extreme laws, bounded by the desires of their constituents and the goals of their parties. These lawmaking strategies and resulting policy subsequently affect how likely individuals are to approve of elite institutions and the lawmakers who embody them.
I pair this substantive interest with a broad one in political methodology. I want to make the appropriate model easier to identify, easier to use, and easier to interpret for substantive researchers. I've also written some pieces on teaching political methodology, drawing on my own in-class experience.
Below are texts of virtually all of my publications (except books). I update the ungated copies when the articles have been published (not forthcoming). You'll also find all of the replication data for which I am the contact author. If you're interested in data or replication material for other publications, please contact my co-authors!
Jordan, Soren and Andrew Q. Philips. ``Improving the Interpretation of Random Effects Regression Results.'' Forthcoming at Political Studies Review. DOI: 10.1177/14789299211068418
We make two claims about random effects models: they result in quasi-demeaning that affects substantive interpretation, and they often result in a vanilla regression specification. We develop some simple code to help with the former. Please see the Computing page for more information.

Jordan, Soren, Grant Ferguson, and Kathryn Haglin. 2022. ``Measuring and Framing Support for Universal Basic Income.'' Social Policy & Administration 56 (1): 138-147. Partially funded by a Hayek Fund award for $3,000. DOI: 10.1111/SPOL.12760
We use a survey experiment to determine whether framing UBI through a lens of values or policy considerations, as well as priming respondents to consider negative or positive arguments about the policy, changes support for UBI. We find support for UBI is strongly related to partisanship, and experimental frames matter most to cross-pressured individuals. (Presented at MPSA in 2020.)
Haglin, Kathryn, Soren Jordan, Alison Higgins Merrill, and Joseph Daniel Ura. 2021. ``Ideology and Specific Support for the Supreme Court.'' Political Research Quarterly 74 (4): 955-969. DOI: 10.1177/1065912920950482
We present a theory of specific support of the Supreme Court in which liberals and conservatives operate asymmetrically. The Court should be asymmetrically punished for being too liberal, rather than too conservative. Corresponding author: Joseph Daniel Ura. (Presented at MPSA in 2017.)
Jo, Hyeran, Joshua Alley, Yohan Park, and Soren Jordan. 2021. ``Signaling Restraints: International Engagement and Rebel Groups' Commitment to International Law.'' International Interactions 47 (5): 928-954. DOI: 10.1080/03050629.2020.1814761

We present new measures of electoral polarization. We then evaluate the effect of presidents on polarization, both generally and within the individual parties, using Box-Tiao multiple impact assessments. We find presidents are central to polarization. Corresponding author: B. Dan Wood. (Presented at APSA in 2015.)

We generate novel empirical data on the nature of ideology in the public, paired with detailed historical accounts of party conflict (largely the work of B. Dan Wood), to illustrate the historical nature of polarization and its fundamental ties to economic policy. Corresponding author: B. Dan Wood.

In Congress Reconsidered, eds. Lawrence C. Dodd and Bruce I. Oppenheimer. Eleventh edition. Los Angeles: Congressional Quarterly Press, pp. 119-137.
We pair the Partisan Polarization and Issue Complexity theory of representation with the evolving polarization of issues to predict changes in issue representation over time.
Jordan, Soren, and Cynthia J. Bowling. 2016. ``The State of Polarization in the States.'' State and Local Government Review 48 (4): 220-226. DOI: 10.1177/0160323X17699527
We provide an initial investigation of recent advances in data availability on state legislatures to illustrate the progress of elite polarization in the American states.
Jordan, Soren and Grant Ferguson. 2016. ``Extremism in Survey Measures of Ideology.'' Research & Politics 3 (3): DOI: 10.1177/2053168016669743
We use the 1989 ANES Pilot Study to evaluate the effects caused by anchoring the common ideology question with the word ``very'' versus ``extremely.'' We find that more individuals indicate a strong ideology when asked if they are ``very'' versus ``extremely'' ideological, but these same respondents do not have strong ideological policy preferences. This work has implications for measuring polarization using general ideology. (Presented at SPSA in 2012.)
