    A Pragmatic Argument Against Equal Weighting.Ittay Nissan-Rozen & Levi Spectre - forthcoming - Synthese.
    We present a minimal pragmatic restriction on the interpretation of the weights in the “Equal Weight View” (and, more generally, in the “Linear Pooling” view) regarding peer disagreement and show that the view cannot respect it. Based on this result we argue against the view. The restriction is the following one: if an agent, i, assigns an equal or higher weight to another agent, j, (i.e. if i takes j to be as epistemically competent as him or epistemically superior to (...)

    Against Moral Hedging.Ittay Nissan-Rozen - 2015 - Economics and Philosophy (3):1-21.
    It has been argued by several philosophers that a morally motivated rational agent who has to make decisions under conditions of moral uncertainty ought to maximize expected moral value in his choices, where the expectation is calculated relative to the agent's moral uncertainty. I present a counter-example to this thesis and to a larger family of decision rules for choice under conditions of moral uncertainty. Based on this counter-example, I argue against the thesis and suggest a reason for its failure (...)

    How to Be an Ex-Post Egalitarian and an Ex-Ante Paretian.Ittay Nissan-Rozen - 2017 - Analysis 77 (3):550-558.
    It is well known that there is a conflict between three intuitive principles for the evaluation of risky prospects in distributional contexts, Ex-Post Egalitarianism, Ex-Ante Pareto and Dominance. In this paper, I return to Peter Diamond’s suggestion that we reject Dominance as a principle of rationality in distributional contexts and present a new argument in support of this position. The argument is based on an observation regarding the right way for a distributor to weigh reasons for actions. In some cases, (...)

  5. Jeffrey Conditionalization, the Principal Principle, the Desire as Belief Thesis, and Adams's Thesis.Ittay Nissan-Rozen - 2013 - British Journal for the Philosophy of Science 64 (4):axs039.
    I show that David Lewis’s principal principle is not preserved under Jeffrey conditionalization. Using this observation, I argue that Lewis’s reason for rejecting the desire as belief thesis and Adams’s thesis applies also to his own principal principle. 1 Introduction2 Adams’s Thesis, the Desire as Belief Thesis, and the Principal Principle3 Jeffrey Conditionalization4 The Principal Principles Not Preserved under Jeffrey Conditionalization5 Inadmissible Experiences.

    Newcomb Meets Gettier.Ittay Nissan-Rozen - 2017 - Synthese 194 (12):4799-4814.
    I show that accepting Moss’s claim that features of a rational agent’s credence function can constitute knowledge, together with the claim that a rational agent should only act on the basis of reasons that he knows, predicts and explains evidential decision theory’s failure to recommend the right choice for the Newcomb problem. The Newcomb problem can be seen, in light of Moss’s suggestion, as a manifestation of a Gettier case in the domain of choice. This serves as strong evidence for (...)

    A Triviality Result for the “Desire by Necessity” Thesis.Ittay Nissan-Rozen - 2015 - Synthese 192 (8):2535-2556.
    A triviality result for what Lewis called “the Desire by Necessity Thesis” and Broome : 265–267, 1991) called “the Desire as Expectation Thesis” is presented. The result shows that this thesis and three other reasonable conditions can be jointly satisfied only in trivial cases. Some meta-ethical implications of the result are discussed. The discussion also highlights several issues regarding Lewis ’ original triviality result for “the Desire as Belief Thesis” that have not been properly understood in the literature.

    Can an Irrational Agent Reason Himself to Rationality?Ittay Nissan-Rozen - 2010 - Working Papers- The Choice Group.
    When an agent that accepts transitivity of preferences as a principle of rationality finds himself expressing intransitive preferences, he has to change some of his expressed preferences so that transitivity will be restored. When such an agent also believes in the existence of some independent betterness relation among the alternatives over which he forms his preferences, it is reasonable to demand that the way he changes his intransitive expressed preferences will be sensitive to his beliefs regarding this betterness relation. It (...)

  9. Reasoning with Comparative Moral Judgements: An Argument for Moral Bayesianism.Ittay Nissan-Rozen - 2017 - In Rafal Urbaniak & Gillman Payette (eds.), Applications of Formal Philosophy - The Road Less Travelled. Cham: Springer. pp. 113-136.
    The paper discusses the notion of reasoning with comparative moral judgements (i.e judgements of the form “act a is morally superior to act b”) from the point of view of several meta-ethical positions. Using a simple formal result, it is argued that only a version of moral cognitivism that is committed to the claim that moral beliefs come in degrees can give a normatively plausible account of such reasoning. Some implications of accepting such a version of moral cognitivism are discussed.

    Doing the Best One Can: A New Justification for the Use of Lotteries.Ittay Nissan-Rozen - 2012 - Erasmus Journal for Philosophy and Economics 5 (1):45-72.
    : In some cases in which rational and moral agents experience moral uncertainty, they are unable to assign exact degrees of moral value—in a non-arbitrary way—to some of the different acts available to them, and so are unable to choose with certainty the best act. This article presents a new justification for the use of lotteries in this kind of situation. It is argued that sometimes the only rational thing for a morally motivated agent to do here is to use (...)

    Contrastive Explanations, Crystal Balls and the Inadmissibility of Historical Information.Ittay Nissan-Rozen - unknown
    I argue for the falsity of what I call the "Admissibility of Historical Information Thesis". According to the AHIT propositions that describe past events are always admissible with respect to propositions that describe future events. I first demonstrate that this demand has some counter-intuitive implications and then argue that the source of the counter-intuitiveness is a wrong understanding of the concept of chance. I also discuss the relation between the failure of the AHIT and the existence of contrastive explanations for (...)
