Empirical Legal Studies
Oliver Wendell Holmes's notion of the marketplace of ideas—that the best test of truth is the power of an idea to get itself accepted in the competition of the market— is a central idea in free speech thought. Yet extant social science evidence provides at best mixed support for the metaphor's veracity, and thus for the view that the truth of a proposition has substantial explanatory force in determining which propositions will be accepted and which not. But even if establishing an open marketplace for ideas is unlikely to produce a net gain in human knowledge, it may have other consequences. We illustrate how to empirically study the consequences of establishing or restricting a communicative domain. Our focus is on time, place, and manner restrictions, and we examine two potential natural experiments involving speech buffer zones around polling places and health care facilities providing abortions. Using a regression discontinuity design with geocoded polling information for over 1.3 million voters in two high-density jurisdictions (Hudson County and Manhattan), we provide suggestive evidence that speech restrictions in Hudson County reduced turnout amongst voters in the buffer zone. By failing to cue voters of the election, speech restrictions may have unanticipated costs. And using difference-in-differences and synthetic control matching with state-level data from 1973 to 2011, we illustrate how one might study the impact of speech restrictions around health care facilities. Although the evidence is limited, Massachusetts’s restrictions were accompanied, if anything, by a decrease in the abortion rate. Buffer zones might channel speech toward more persuasive forms, belying the notion that the cure for bad speech is plainly more speech.
Constitutional law casebooks, generations of constitutional lawyers, and the Justices themselves say that the Court is more likely to depart from precedent in constitutional cases than in other types. We test this assumption in cases decided by the Roberts Court and find, at odds with earlier studies, that the data provide inconclusive support for it. Other factors, especially criticism of precedent by lower courts and lawyers, are more consistent and stronger predictors of the Court's decisions to depart from precedent. These findings have interesting implications for lawyering, teaching, and judging in the constitutional law context.
Supreme Court doctrine grants special protection against laws that "chill" protected speech, most prominently via the overbreadth doctrine. The overbreadth doctrine permits persons whose own speech is unprotected to challenge laws that infringe the protected speech of third parties. The Court has not generally applied overbreadth and the other speech-protective doctrines to other constitutional rights even though other rights could also be subject to a chilling effect. The case law simply assumes that the chilling effect only acts on the exercise of speech, and that this justifies treating speech differently from other rights.
We tested these assumptions with respect to abortion rights. By comparing abortion rates with state laws over a two-decade-plus period, we found a statistically significant correlation between laws forbidding late-term abortions and the reduction of not only late-term but also "near-late-term" abortions, i.e., abortions in the roughly one month before the period in which abortions are forbidden. That effect persists even after controlling for potentially confounding variables, such as the number of abortion providers and pro-life public opinion. Moreover, the effect is not limited to the year of enactment or associated with failed policy initiatives, suggesting that the impact is due to the law itself rather than associated publicity. These findings are consistent with, and strongly suggestive of, a chilling effect on abortion providers and/or women seeking abortions. This result undermines the implicit assumption that the chilling effect is unique to laws regulating speech and vindicates the general proposition that laws can chill the exercise of constitutional rights beyond their literal coverage.
In its landmark campaign finance decision Citizens United v. FEC, the Supreme Court found that favoritism or influence over elected officials gained by wealthy campaign contributors does not—in the absence of outright corruption—give rise to the sort of constitutional harm that would justify restrictions on campaign spending. The Court was also insistent that any perceptions of ingratiation would not undermine the electorate’s faith in democracy. This paper challenges the doc- trinal and empirical underpinnings of those assertions. We argue that a loss of faith by the electorate implicates a central constitutional value and is a sufficiently compelling interest to justify campaign finance regulation. We also demonstrate empirically that the Court should not have been so confident that the elecorate's faith in democracy is unaffected either by the appearance of influence or access due to campaign spending or by independent expenditures.
The Supreme Court's decision in Shaw v. Reno established an "analytically distinct" constitutional claim of racial gerrymandering for majority-minority districts drawn predominantly on the basis of race. The case was and continues to be controversial, because the precise nature of the injury caused by such districts has been a persistent source of debate. Shaw districts did not minimize a group's representation, but rather they communicated an "expressive harm" due to signals they sent to the electorate and representatives that the jurisdiction relied too much on race in the construction of a district. Such districts, the Court argued, communicated racial stereotypes that individuals belonging to the same racial group were politically interchangeable, despite their many social and economic differences. This paper tests the "Shaw hypothesis" with recent survey data. We find no patterns in racial attitudes based on the shape and racial composition of a congressional district. We do, however, find substantial and expected gaps among racial groups concerning attitudes toward the practice of majority-minority districting, Section 5 of the Voting Rights Act, and job approval of the respondent's representative.
We live in the age of empiricism, and in that age, constitutional law is a relative backwater. Although quantitative methods have transformed entire fields of scholarly inquiry, reshaping what we ask and what we know, those who write about the Constitution rarely resort to quantitative methodology to test their theories. That seems unfortunate, because empirical analysis can illuminate important questions of constitutional law. Or, at least, that is the question to be tested in this Symposium.
We brought together a terrific group of scholars with a unique assignment. We paired distinguished constitutional thinkers with equally accomplished empiricists. We asked the law scholars to identify a core question, assumption, or doctrine from constitutional law, and we asked the empiricist to take a cut at answering it, or at least at figuring out how one might try to answer it. We understood that their answers might be preliminary at best, that the questions might be resistant to easy answers. This is so, in part, because empiricism is as much a means of refining questions as it is a way of answering them.
The balance of this Foreword is, in a sense, an introduction to the idea that more serious empirical analysis can further both constitutional law scholarship and constitutional law decisionmaking. Hence our title: Testing the Constitution.
The Federal Sentencing Guidelines were promulgated in response to concerns of widespread disparities in sentencing. After almost two decades of determinate sentencing, the Guidelines were rendered advisory in United States v. Booker. How has greater judicial discretion affected interjudge disparities, or differences in sentencing outcomes that are attributable to the mere happenstance of the sentencing judge assigned? This Article utilizes new data covering almost 400,000 criminal defendants linked to sentencing judges to undertake the first national empirical analysis of interjudge disparities after Booker.
The results are striking: Interjudge sentencing disparities have doubled since the Guidelines became advisory. Some of the recent increase in disparities can be attributed to differential sentencing behavior associated with judge demographic characteristics, with Democratic and female judges being more likely to exercise their enhanced discretion after Booker. Newer judges appointed post-Booker also appear less anchored to the Guidelines than judges with experience sentencing under the mandatory Guidelines regime.
Disentangling the effects of various actors on sentencing disparities, I find that prosecutorial charging is likely a prominent source of disparities. Rather than charging mandatory minimums uniformly across eligible cases, prosecutors appear to selectively apply mandatory minimums in response to the identity of the sentencing judge, potentially through superseding indictments. Drawing on this empirical evidence, this Article suggests that recent sentencing proposals calling for a reduction in judicial discretion in order to reduce disparities may overlook the substantial contribution of prosecutors.
This Article empirically examines an issue central to judicial and scholarly debate about civil rights damages actions: whether law enforcement officials are financially responsible for settlements and judgments in police misconduct cases. The Supreme Court has long assumed that law enforcement officers must personally satisfy settlements and judgments, and has limited individual and government liability in civil rights damages actions—through qualified immunity doctrine, municipal liability standards, and limitations on punitive damages—based in part on this assumption. Scholars disagree about the prevalence of indemnification: Some believe officers almost always satisfy settlements and judgments against them, and others contend indemnification is not a certainty. In this Article, I report the findings of a national study of police indemnification. Through public records requests, interviews, and other sources, I have collected information about indemnification practices in forty-four of the largest law enforcement agencies across the country, and in thirty-seven small and mid-sized agencies. My study reveals that police officers are virtually always indemnified: During the study period, governments paid approximately 99.98% of the dollars that plaintiffs recovered in lawsuits alleging civil rights violations by law enforcement. Law enforcement officers in my study never satisfied a punitive damages award entered against them and almost never contributed anything to settlements or judgments—even when indemnification was prohibited by law or policy, and even when officers were disciplined, terminated, or prosecuted for their conduct. After describing my findings, this Article considers the implications of widespread indemnification for qualified immunity, municipal liability, and punitive damages doctrines; civil rights litigation practice; and the deterrence and compensation goals of 42 U.S.C. § 1983.
Stark racial disparities define America’s relationship with the death penalty. Though commentators have scrutinized a range of possible causes for this uneven racial distribution of death sentences, no convincing evidence suggests that any one of these factors consistently accounts for the unjustified racial disparities at play in the administration of capital punishment. We propose that a unifying current running through each of these partial plausible explanations is the notion that the human mind may unwittingly inject bias into the seemingly neutral concepts and processes of death penalty administration.
To test the effects of implicit bias on the death penalty, we conducted a study on 445 jury-eligible citizens in six leading death penalty states. We found that jury-eligible citizens harbored two different kinds of the implicit racial biases we tested: implicit racial stereotypes about Blacks and Whites generally, as well as implicit associations between race and the value of life. We also found that death-qualified jurors—those who expressed a willingness to consider imposing both a life sentence and a death sentence—harbored stronger implicit and self-reported (explicit) racial biases than excluded jurors. The results of the study underscore the potentially powerful role of implicit bias and suggest that racial disparities in the modern death penalty could be linked to the very concepts entrusted to maintain the continued constitutionality of capital punishment: its retributive core, its empowerment of juries to express the cultural consensus of local communities, and the modern regulatory measures that promised to eliminate arbitrary death sentencing.
This Article identifies how the current spate of state and local regulation is changing the way elected officials, scholars, courts, and the public think about the constitutional dimensions of immigration law and governmental responsibility for immigration enforcement. Reinvigorating the theoretical possibilities left open by the Supreme Court in its 1875 Chy Lung v. Freeman decision, state and local officials characterize their laws as unavoidable responses to the policy problems they face when they are squeezed between the challenges of unauthorized migration and the federal government’s failure to fix a broken system. In the October 2012 term, in Arizona v. United States, the Court addressed, but did not settle, the difficult empirical, theoretical, and constitutional questions necessitated by these enactments and their attendant justifications. Our empirical investigation, however, discovered that most state and local immigration laws are not organic policy responses to pressing demographic challenges. Instead, such laws are the product of a more nuanced and politicized process in which demographic concerns are neither necessary nor sufficient factors and in which federal inactivity and subfederal activity are related phenomena, fomented by the same actors. This Article focuses on the constitutional and theoretical implications of these processes: It presents an evidence-based theory of state and local policy proliferation; it cautions legal scholars to rethink functionalist accounts for the rise of such laws; and it advises courts to reassess their use of traditional federalism frameworks to evaluate these subfederal enactments.
