Why the Supreme Court agrees to hear cases is among the most important topics in judicial politics. However, existing theories have overlooked a key factor: the relative ideologies of the litigating parties. We develop and test a new theory that explicitly incorporates the ideology of the litigating parties in explaining which cert petitions the Court is likely to grant. Specifically, we theorize that cert petitions are more successful when (1) there is great ideological distance between the two opposing parties and (2) the lower-court appeals panel is closest ideologically to the party who won at the appellate level. In these cases, the party petitioning the Court to intervene becomes the “Odd Party Out,” which conveys information about both the importance of the case and the possibility of ideological bias against the petitioner. We test this theory using a new dataset on the identities and ideologies of advocates and judges for federal court cases that generated cert petitions from 2003 to 2015. We find strong support for the theory: petitions are more likely to be granted when the petitioning party is the ideological Odd Party Out.
What are the downstream political consequences of state activity explicitly targeting a minority group? This question is well studied in the comparative context, but less is known about the effects of explicitly racist state activity in liberal democracies such as the United States. We investigate this question by looking at an important event in American history---the internment of people of Japanese ancestry during World War II. We find that Japanese Americans who were interned or had family who were interned are significantly less politically engaged and that these patterns of demobilization increase with internment length. Using an identification strategy leveraging quasi-random camp assignment, we also find that camp experience matters: those who went to camps that witnessed violence or strikes experienced sharper declines. Taken together, our findings contribute to a growing literature documenting the demobilizing effects of ethnically targeted detention and expand our understanding of these forces within the U.S.
How do we know whether judges of different backgrounds are "biased"? We review the substantial political science literature on judicial decision-making, paying close attention to how judges' demographics and ideology can influence or structure their decision-making. As the research shows, characteristics such as race, ethnicity, and gender can sometimes predict judicial decision-making in limited kinds of cases; however, the literature also suggests that these are by far less important in shaping or predicting outcomes than is ideology (or partisanship), which in turn correlates closely with gender, race, and ethnicity. This leads us to conclude that assuming judges of different backgrounds are biased because they rule differently is questionable: given that the application of the law rarely provides a ``correct'' answer, it is no surprise that judges' decisions vary according to their personal backgrounds and, more importantly, according to their ideology.
Though used frequently in machine learning, boosted decision trees are largely unused in political science, despite many useful properties. We explain how to use one variant of boosted decision trees, AdaBoosted decision trees (ADTs), for social science predictions. We illustrate their use by examining a well-known political prediction problem, predicting U.S. Supreme Court rulings. We find that our ADT approach outperforms existing predictive models. We also provide two additional examples of the approach, one predicting the onset of civil wars and the other predicting county-level vote shares in U.S. presidential elections.
Supreme Court justices employ law clerks to help them perform their duties. We study whether these clerks influence how justices vote in the cases they hear. We exploit the timing of the clerkship hiring process to link variation in clerk ideology to variation in judicial voting. To measure clerk ideology, we match clerks to the universe of disclosed political donations. We find that clerks exert modest influence on judicial voting overall, but substantial influence in cases that are high-profile, legally significant, or close decisions. We interpret these results to suggest that clerk influence occurs through persuasion rather than delegation of decision-making authority.
Do Justices telegraph their preferences during oral arguments? We demonstrate that Justices implicitly reveal their leanings during oral arguments, even before arguments and deliberations have concluded. Specifically, we extract the emotional content of over 3,000 hours of audio recordings spanning 30 years of oral arguments before the Court. Using only the level of emotional arousal in each of the Justices’ voices during these arguments, as measured by their vocal pitch, we are able to accurately predict many of their eventual votes, while using none of the text or substantive content. These predictions are statistically and practically significant and robust to including a range of controls. Our findings suggest that mannerisms that may be subconscious, such as vocal pitch, carry information that basic legal, political, and textual information do not, and can be used to predict the decisions of even elite political actors.
We study of the ideological balance of the legal academy and compare it to the ideology of the legal profession more broadly. To do so, we match professors listed in the Association of American Law Schools Directory of Law Teachers and lawyers listed in the Martindale-Hubbell directory to a measure of political ideology based on political donations. We find that 15 percent of law professors, compared to 35 percent of lawyers, are conservative. This may not simply be due to differences in their backgrounds: the legal academy is still 11 percentage points more liberal than the legal profession after controlling for several relevant individual characteristics. We argue that law professors’ ideological uniformity marginalizes them, but that it may not be possible to improve the ideological balance of the legal academy without sacrificing other values.
We present an approach to investigating causal mechanisms in survey experiments that leverages the provision or withholding of information on potentially important mediating variables. The designs we propose can identify the controlled direct effect of a treatment and also what we call an intervention effect. These quantities can be used to address substantive questions about causal mechanisms, can be identified under weaker assumptions than current approaches to causal mechanisms, and can be estimated with simple estimators using standard statistical software. Furthermore, these methods are compatible with a broad range of experimental designs, including survey vignettes and conjoint designs. We illustrate the approach via two examples, one on evaluations of potential U.S. Supreme Court nominees and the other on public perceptions of the democratic peace.
The standard approach in positive political theory posits that action choices are the consequences of preferences. Social psychology—in particular, cognitive dissonance theory—suggests the opposite: preferences may themselves be affected by action choices. We present a formal framework that applies this idea to three models of political choice: (1) one in which partisanship emerges naturally in a two party system despite policy being multi-dimensional, (2) one in which interactions with people who express different views can lead to empathetic changes in political positions, and (3) one in which ethnic or racial hostility increases after acts of violence. These examples demonstrate how incorporating the insights of social psychology can expand the scope of formalization in political science.
Ever since the Carter Administration began appointing female and minority judges in large numbers, scholars have sought to measure their impact. In this Article, I focus on a different, but equally important question: what is the background and ideology of female and minority judges and how has this changed over time? I address this issue empirically by analyzing quantitative data on United States district court judges from Presidents Lyndon Johnson through Barack Obama. My findings are twofold: First, I show that the professional and educational characteristics of female and minority judges have historically differed from those of white male judges, but these differences have narrowed over time, particularly when it comes to education. Second, I present evidence showing that, even though professional and educational differences have narrowed, female and minority judges still bring a different ideological viewpoint than do white male judges, being on average more left-leaning in their ideology. These findings reframe existing discussions about descriptive representation in the courts and suggest that female and minority judges more than ever tend to share professional and educational backgrounds with white or male judges, but still bring a different, albeit more liberal, perspective.
What predicts attempts at judicial reform? We develop a broad, generalizable framework that both explains and predicts attempts at judicial reform. Specifically, we explore the political tug of war created by the polarization between the bar and political actors, in tandem with existing judicial selection mechanisms. The more liberal the bar and the more conservative political actors, the greater the incentive political actors will have to introduce ideology into judicial selection. (And, vice versa, the more conservative the bar and the more liberal political actors, the greater incentive political actors will have to introduce ideology into judicial selection.) Understanding this dynamic, we argue, is key to both explaining and predicting attempts at judicial reform. For example, under most ideological configurations, conservatives will, depending on how liberal they perceive the bar to be, push reform efforts toward partisan elections and executive appointments, while liberals will work to maintain merit-oriented commissions. We explore the contours of this predictive framework with three in-depth, illustrative case studies: Florida in 2001, Kansas in the 2010s, and North Carolina in 2016.
We present a new measure of judicial ideology based on judicial hiring behavior. Specifically, we utilize the ideology of the law clerks hired by federal judges to estimate the ideology of the judges themselves. These Clerk-Based Ideology (CBI) scores complement existing measures of judicial ideology in several ways. First, CBI scores can be estimated for judges across the federal judicial hierarchy. Second, CBI scores can capture temporal changes in ideology. Third, CBI scores avoid case selection and strategic behavior concerns that plague existing vote-based measures. We illustrate the promise of CBI scores through a number of applications.
We study the political ideology of judicial law clerks in the United States, by constructing a novel dataset that combines information on the identity of clerks with a measure of political ideology based on political donations. We then use this data to empirically investigate several important questions about the ideologies of clerks. First, we examine whether clerks tend to share the liberal ideology of other lawyers or the more conservative ideology associated with federal judges and find that clerks tend to be disproportionately liberal. Second, we investigate how the ideology of clerks compares to the ideology of lawyers and find that liberal lawyers are more likely to have clerked than conservatives. Third, we assess whether the ideology of clerks differs based on the level of clerkship and find that the liberal skew becomes less pronounced as the prestige of the clerkship increases. Fourth, we analyze how ideology influences the hiring of clerks and find that the ideology of judges is strongly correlated with the ideology of their clerks.
We extend the scaling methodology previously used in Bonica (2014) to jointly scale the American federal judiciary and legal profession in a common-space with other political actors. The end result is the first data set of consistently measured ideological scores across all tiers of the federal judiciary and the legal profession, including 840 federal judges and 380,307 attorneys. To illustrate these measures, we present two examples involving the U.S. Supreme Court. These data open up significant areas of scholarly inquiry.
How do Americans evaluate potential U.S. Supreme Court candidates? Using a novel, two-part conjoint experiment, I show that respondents put high importance on the political leanings of potential Court candidates, a finding in contrast with the scholarly view that the public views the Court as different from other, more political institutions. Indeed, when respondents are given information about a nominee’s partisan leanings they rely extensively on that information in de- ciding whether to support the candidate, whether they trust the candidate, and whether they find the candidate qualified. By contrast, when partisan information is withheld, respondents appear to use other kinds of signals, such as race, in order to fill in the gaps. Those who are most knowledgeable about the Court are most influenced by these partisan signals, providing further support for the importance of political heuristics. The results suggest that the public’s evaluation of judicial nominees is more in line with how it evaluates other political actors. They also suggest that even candidates with excellent qualifications need not garner bipartisan public support.
Using a new dataset capturing the ideological positioning of nearly half a million U.S. judges and lawyers, we present evidence showing how ideology affects the selection of judges across federal and state judiciaries. We document that the higher the court, the more it deviates ideologically from the ideology of attorneys, suggesting ideology plays a strong role in judicial selection. We also show ideology plays stronger roles in jurisdictions where judges are selected via political appointments or partisan elections. Our findings suggest that ideology is an important component of judicial selection primarily where (1) using ideology leads to expected benefits to politicians, (2) when the jurisdiction's selection process allows ideology to be used, and (3) where it concerns the most important courts. The study is the first to provide a direct ideological comparison across judicial tiers and between judges and lawyers and to explain how and why American courts become politicized.
Judicial nominees to federal courts rarely reveal their genuine views on controversial issues. As a result, political actors---and especially the Senate---often have only partial information about how a nominee would vote on issues likely to come before the courts. We formulate a model that departs from the previous literature by incorporating this type of uncertainty into the nominations process. Our model shows that the absence of such information can yield suboptimal outcomes. In particular, when the President and Senate are ideologically divergent, low information about nominees' views results in the Senate occasionally rejecting acceptable nominees. Thus, even though low information allows the President to ``sneak in" more extreme candidates, it leads to both the President and the Senate being worse off than they would be with more transparency. Under such conditions, more information weakly increases both sides' welfare. Our results therefore raise questions about why nominees are permitted to keep important views private.
Does encouragement help address gender imbalances in technical fields? We present the results of one of the first and largest randomized controlled trials on the topic. Using an applied statistics conference in the social sciences as our context, we randomly assigned half of a pool of 3,945 graduate students to receive two personalized emails encouraging them to apply (n = 1,976) and the other half to receive nothing (n = 1,969). We find a robust, positive effect associated with this simple intervention and suggestive evidence that women responded more strongly than men. However, we find that women’s conference acceptance rates are higher within the control group than in the treated group. This is not the case for men. The reason appears to be that female applicants in the treated group solicited supporting letters at lower rates. Our findings therefore suggest that “low dose” interventions may promote diversity in STEM fields but may also have the potential to expose underlying disparities when used alone or in a non-targeted way.
clairecmIt's just that most options parents relied on aren't available now. It comes down to this: Young kids need child care & help with remote school, and can't be in big groups. So they require an adult at home, paid or unpaid. For many families, that's asking the impossible.
