Summary. The United States spends many billions of dollars on its system of civil litigation, and expert witnesses appear in a huge portion of cases. Yet litigants select and retain expert witnesses in ways that create the appearance of biased hired guns on both sides of every case, thereby depriving factfinders of a clear view of the facts. As a result, factfinders too often arrive at the wrong conclusions, thus undermining the deterrence and compensation functions of litigation. Court-appointment of experts has been widely proposed as a solution, yet it raises legitimate concerns about accuracy and has failed to gain traction in the American adversarial system.

Summary. The modern capitalist society, characterized by decentralized decision making and increasingly sophisticated products and services, turns on relationships of epistemic reliance, where laypersons depend upon advisors to guide their most important decisions. Yet many of those advisors lack real expertise and may be biased by conflicting interests. In such situations, laypersons are likely to make suboptimal decisions that sometimes aggregate into systematic failures, from soaring health care costs to market crashes. Regulators can attempt to manage the symptoms and worst abuses, but the fundamental problem of biased advice will remain. There are many potential policy solutions, from outright bans on conflicting interests to disclosure mandates, yet their comparative effectiveness is poorly understood. By constructing a decision task for human subjects and providing advice in various scenarios, this Article reports new experiments testing alternative policy mechanisms. Prior research has shown that disclosure mandates can be deleterious if they make advisors more biased, but this paper contextualizes those findings. It turns out that disclosures may be valuable in settings where relative expertise is low, but deleterious where relative expertise is high. By also disaggregating the data, one finds that disclosures of conflicting interests may hurt laypersons in the majority of situations where the conflicted advice is not actually biased. Thus, the evidence suggests that, if they are to be at all effective, disclosure mandates should be narrowly tailored. Most importantly, the evidence shows that a disclosure mandate improves layperson performance when unbiased advisors are also available. Yet laypersons appear to be poor judges of their need for unbiased advice, so market mechanisms may be ineffective for provisioning unbiased advice. In the end, the presence of an unbiased advisor is the strongest determinant of layperson performance, and thus policymakers must develop ways of aligning the interests of advisors and laypersons. Pay-for-performance, blinding of experts, and mandatory or subsidized second-opinion policies are likely to be helpful in aligning these interests.

Summary. In a recent symposium article (Expert Mining and Required Disclosure, 81 U Chi. L. Rev. 131 (2014)), Professor Jonah Gelbach discusses the problem that a litigant in the American adversarial system can consult multiple expert witnesses on a given question but only disclose the single most favorable opinion to the fact finder (a jury, judge, or arbitrator). He calls this the problem of “expert mining.” In particular, Gelbach considers whether a policy that requires litigants to disclose to the fact finder the number of experts that they consulted might be a satisfactory solution to the problem. Alternatively, Gelbach considers whether an even more radical change to the American litigation system — the exclusion of all expert opinions rendered after the first one — might be necessary. In doing so, Gelbach extensively discusses my own work on this problem and the third solution I developed in a 2010 article, Blind Expertise, 85 NYU L. Rev. 174 (2010). There, I show that expert mining is one part of a broader problem of expert bias, and I propose a conditional-disclosure rule as the solution. This Essay provides some analysis of Gelbach’s framing of the problem, reviews the blinding proposal, and identifies the limits of Gelbach’s analyses.

Summary. The country deserves stable institutions it can trust. President Trump can continue tweeting, but he should not be allowed to put our public health and our economy in jeopardy.

Summary. Prosecutors can force witnesses to testify and use perjury prosecutions to hold them to the provable truth. More controversially, prosecutors also offer witnesses inducements for favorable testimony, including leniency, immunity, and even cash. This ubiquitous behavior would be illegal as witness bribery, except for a longstanding tradition of sovereigns using this power, which legal doctrine now reflects. A causal analysis shows that even if prosecutors use this power only in good faith, these inducements undermine the epistemic value of witness testimony.

Summary. “Blind expertise” has been proposed as an institutional solution to the problem of bias in expert witness testimony in litigation, as a way to improve litigation outcomes. At the request of a litigant, an intermediary selects a qualified expert and pays the expert to review a case without knowing which side requested the opinion. This paper reports an experiment that tests the hypothesis that, compared to traditional experts, such “blinded experts” will be more persuasive to jurors. A national sample of mock jurors (N = 275) watched an online video of a staged medical malpractice trial, including testimony from two medical experts, one of which (or neither, in the control condition) was randomly assigned to be a blind expert. We also manipulated whether the judge provided a special jury instruction explaining the blinding concept.

Summary. The Supreme Court says that campaign finance regulations are unconstitutional unless they target “quid pro quo” corruption or its appearance. To test

Summary. Physicians discriminate among trials of varying degrees of rigor, but industry sponsorship negatively influences their perception of methodologic quality and reduces their willingness to believe and act on trial findings, independently of the trial's quality. These effects may influence the translation of clinical research into practice.
