1. Consider, for instance, the holding in the seminal case, Apprendi v. New Jersey, 530 U.S. 466, 490 (2000), that “any fact that increases the penalty for a crime beyond the prescribed statutory maximum must be submitted to a jury, and proved beyond a reasonable doubt.” The phrase “must be submitted to a jury, and proved beyond a reasonable doubt” is repeated throughout the Supreme Court jurisprudence; see, e.g., Blakely v. Washington, 542 U.S. 296, 301 (2004).

9. Before proceeding, let me mention two preliminary points. First, because the focus of this article is on a relationship between the right of jury trial and the requirement of proof beyond a reasonable doubt, it assumes that the proof beyond a reasonable doubt requirement is normatively desirable and does not relitigate the debate over its wisdom. For some recent criticisms of the requirement, see, e.g., Epps, Daniel, The Consequences of Error in Criminal Justice , 128 Harv. L. Rev. 1065 (2015)Google Scholar; Laudan, Larry, Is It Finally Time to Put “Proof beyond a Reasonable Doubt” out to Pasture? , The Routledge Companion to Philosophy of Law 317 (Marmor, Andrei ed., 2012)Google Scholar; Laudan, Larry, The Rules of Trial, Political Morality, and the Costs of Error: Or, Is Proof beyond a Reasonable Doubt Doing More Harm Than Good? , in 1 Oxford Studies in Philosophy of Law 195 (Green, Leslie & Leiter, Brian eds., 2011)CrossRefGoogle Scholar; Laudan, Larry, The Elementary Epistemic Arithmetic of Criminal Justice , 5 Episteme 282 (2008)CrossRefGoogle Scholar. For a recent, thorough discussion of the controversy and a defense of the standard, see Walen, Alec, Proof beyond a Reasonable Doubt: A Balanced Retributive Account , 76 La. L. Rev. 355 (2015)Google Scholar. Second, it is fair to ask, in this age of vanishing trials ( Galanter, Marc, The Vanishing Trial: An Examination of Trials and Related Matters in Federal and State Courts , 1 J. Empirical Legal Stud. 459–570 (2004))CrossRefGoogle Scholar, whether it makes sense to focus one's scholarly efforts on trials in the criminal process. See, e.g., William J. Stuntz, The Collapse of American Criminal Justice (2011); Benjamin Weiser, Trial by Jury, a Hallowed American Right, Is Vanishing, N.Y. Times, Aug. 7, 2016. This article assumes that, given the “archetype”-like status that the beyond a reasonable doubt requirement and the right to trial by jury have in our criminal justice system as fundamental constitutional commitments, it is important for scholars to work out the nature and scope of such commitments, even if the actual number of cases that go to trial is small. For a discussion of legal archetypes, see Waldron, Jeremy, Torture and Positive Law: Jurisprudence for the White House , 105 Colum. L. Rev. 1681, 1723 (2005)Google Scholar (defining “archetype” as “a particular provision in a system of norms which has a significance going beyond its normative content, a significance stemming from the fact that it sums up or makes vivid to us the point, purpose, principle, or policy of a whole area of law”). Moreover, even if it is the case that very few cases go to trial, how a criminal case is expected to be resolved at the end of the process can have an impact on the plea-bargaining process. If, for instance, it is the case that the jury unanimity rule makes convictions more difficult than the supermajority rule, then the bargaining positions of relevant parties during plea bargaining would change depending on which voting rule is adopted. Therefore, the fact that there are very few trials does not mean that trials are irrelevant. For a similar defense of focusing on the trial and the standard of proof despite the rarity of trials, see Walen, id. at 401–402.

But it would be unreasonable to be certain of this, even when it is true.”).

31. This number comes from a simple averaging equation: probability of guilt according to those who seek to vote to convict multiplied by the number of those who seek to convict and probability of guilt according to those who seek to acquit multiplied by the number of those who seek to acquit are added to each other and then divided by the number of jurors ((0.9 x 11 + 0.2)/12). There are some disagreements about whether this is a correct understanding of the equal-weight view. Kelly says, for instance, that if a person arrives at an answer with 90 percent confidence and someone else arrives at the same answer with 80 percent confidence, then they should not split the difference and arrive at 85 percent confidence. He says, “Intuitively, learning that you arrived at the same number should make me more confident of my answer, as opposed to less confident, which would be the outcome of averaging our credences.” Kelly, Thomas, Disagreement and the Burdens of Judgment , in Epistemology of Disagreement: New Essays , 31, 35–36 n.4 (Christensen, David & Lackey, Jennifer eds., 2013)Google Scholar. Christensen has a similar discussion. See Christensen, David, Disagreement, Question-Begging, and Epistemic Self-Criticism , 11 Philosophers’ Imprint 1, 3 n.3, 17 (2011)Google Scholar. I do not share this intuition. If I am 90 percent confident of some proposition but my friend is only 60 percent confident, then it seems to me that I, upon learning that my friend is not as confident as I am, should be a bit less confident, and the friend should conversely become a bit more confident. There may be other problems with the equal-weight view, but I do not see the intuitive case for rejecting it on this ground.

35. There is no reason to have two different voting rules for the equal-weight view, because after everyone revises his or her view in light of disagreement, everyone would end up with the same answer every time, thus enabling a unanimous verdict.

36. This table assumes that each person must vote to acquit if the average probability of guilt is less than 0.85.

40. Another decision that this argument vindicates is Burch v. Louisiana, 441 U.S. 139 (1979), which held, despite the Johnson holding which permitted nonunanimous verdicts, that unanimity was required if the size of the jury is six, as opposed to twelve. Burch was decided as a case about the right to trial by jury under the Sixth Amendment, but the equal-weight view suggests that there may also be a reason to endorse the holding as a way of enforcing the beyond a reasonable doubt requirement, given that the weight of each vote in a six-person jury is higher than the weight of each vote in a twelve-person jury.

116. Some may see “consent” as a factual question, and, indeed, if the legal system defines it precisely enough, it could be a mostly factual question. But in order to do so, the legal system would have to define what precisely counts as nonconsent and what to do about situation of mistakes about nonconsent. Formulas like “Yes means yes” leave unspecified answers to questions such as whether either explicit or implicit communication of consent counts, how to tell whether the consent is voluntary (especially in situations of unequal bargaining power), and whether ordinary or reasonable mistakes about nonconsent can exculpate and how one might go about defining “reasonable” mistakes. These issues call for normative judgments, and the legal system rarely has all the questions answered in such a specific manner that there is little room for jurors to exercise their capacities for moral judgments to give content to the idea of consent. For a good overview of the relevant issues, see, e.g., Baron, Marcia, Gender Issues in the Criminal Law , in The Oxford Handbook of Philosophy of Criminal Law 335, 375–381 (Deigh, John & Dolinko, David eds., 2011)Google Scholar.

Kahan's study has also had some influence on legal scholarship. See, e.g., Buell, id. at 574 (crediting Kahan for “demonstrat[ing] that views on the normative question” about “what norms are and should be about consent to sex, particularly for two young people who know each other socially at a school” “vary a great deal”); Capers, I. Bennett, Real Women, Real Rape , 60 UCLA L. Rev. 826 (2013)Google Scholar (citing Kahan's study for its “discussion of how the cultural background and assumptions of jurors have a stronger effect than legal definitions in rape cases”); Kaplan, Margo, Rape beyond Crime , 66 Duke L.J. 1045, 1069 (2017)Google ScholarPubMed (citing what the author calls “Kahan's seminal study” as demonstrating that “social norms about male persistence and female resistance clearly influence[] juror decisions”).
