About

Jacob Ross is an Associate Professor of Philosophy at the University of Southern California, based in the USC School of Philosophy. He holds a BA in Philosophy from the University of Toronto and a PhD in Philosophy from Rutgers University. His research primarily focuses on ethics, epistemology, and practical reason, contributing to these fields through various publications and forthcoming papers. Ross's work explores foundational issues in moral philosophy, such as moral skepticism, the nature of moral blame, and the relationship between moral beliefs and explanations, as well as epistemic topics like knowledge, belief, and meta-epistemic beliefs. He has engaged with complex philosophical problems including the principle of sufficient reason, the nature of personal obligation, and the implications of fission cases for self-interest theories. His approach often involves critical analysis of existing theories and proposing alternative frameworks, demonstrating a deep engagement with both normative and metaethical questions.

• Probabilistic Prejudice

  2026-04-01

  book-chapter1st authorCorresponding

  Abstract This chapter looks at epistemic-moral dilemmas. Recently, a number of philosophers have argued that, in some circumstances, prejudicial beliefs are both morally wrong and rationally required. In order to avoid this conflict, some have argued that belief is morally encroached upon—that is, the standards of epistemic rationality can shift in light of moral considerations. In assessing the moral encroachment thesis, Ross distinguishes between ‘definitive prejudice’ and ‘probabilistic prejudice’. He argues that if the ordinary norms of epistemic rationality that apply to morally neutral beliefs also applied to prejudicial beliefs, then while definitive prejudice would never be rationally required, probabilistic prejudice would be. Hence, he argues, if we are to maintain that probabilistic prejudice is never rationally required, we must accept the moral encroachment thesis. In fact, we must accept a radical version of the thesis affecting the most fundamental rational norms.

• Evaluative Uncertainty

  2026-02-04

  book-chapterSenior author

  Abstract This chapter concerns evaluative uncertainty—uncertainty about values or objective reasons for action. It argues, against some recent sceptics, that evaluative uncertainty is relevant to rational and moral choice. It considers a number of principles from the literature aimed at precisifying this relevance, shows that they all face serious objections, and then proposes alternative principles that avoid these objections. It also discusses two important challenges, known as the problem of intertheoretic value comparison and the problem of fanaticism. The main conclusion of the chapter is that, while a theory of rational and moral choice under evaluative uncertainty is needed, no special theory is needed, because the dominant theory of rational choice under ordinary uncertainty can be extended to rational and moral choice under evaluative uncertainty.

  This doctoral thesis documents the historical evolution and systematic weaponization of fifty terms commonly deployed to dismiss witness testimony and suppress evidence. Each entry traces linguistic development from Proto-Indo-European, Greek, and Latin roots through modern usage, revealing how words originally denoting sacred practices, careful observation, and legitimate coordination have been transformed into tools for silencing witnesses and discrediting testimony.<br>The work demonstrates that "conspiracy" once meant "breathing together," "credibility" meant "placing one's heart in trust," "parasite" was a sacred guest at temple feasts, and "speculation" meant "observing from a watchtower." Through detailed degradation timelines, the thesis documents specific dates, events, and actors involved in weaponization—from the 1605 Gunpowder Plot's impact on "conspiracy" to the 1967 CIA dispatch explicitly weaponizing "conspiracy theorist," from Victorian doctors' weaponization of "hysteria" to modern internet culture's mockery of "triggered."<br>This systematic documentation provides witnesses, researchers, advocates, and anyone facing linguistic dismissal tactics with a comprehensive reference tool. The work builds on the WERD (<b><i>Witnessed Epistemic Restoration Doctrine</i></b>) framework, which recognizes that witnesses possess unique epistemic authority derived from direct experience. When language is weaponized against witness testimony, it serves as a tool of epistemic injustice.<br>Each of the 50 terms includes: Proto-Indo-European/Greek/Latin roots, complete historical evolution, original meanings, degradation timelines with specific attribution, all derivatives (noting which preserve and which destroy original meaning), current weaponized use, and what legitimate practices are erased by weaponization.<br>This thesis represents the culminating work for W.Ph.D. (Witness PhD), a self-granted doctoral credential based on published research in witness authority and linguistic weaponization.<br>

• Extending Personality Rights to Consciousness: The Consciousness Valuation Framework

  preprintOpen access1st authorCorresponding

  A legal and technical framework for protecting real human experience in AI training systems. This paper extends the 2025 R. Madhavan personality rights precedent from surface-level protection (facial appearance) to depth-level protection (consciousness, lived experience, psychological states). Argues that if AI cannot legally deepfake a person's face without permission, it cannot legally train on that person's consciousness without permission and compensation. Establishes parity between legal protections for fictional IP (Mickey Mouse) and real human consciousness. Includes technical implementation via Human Dignity Parity Protocol and Sovereign Shutter™ platform.

• Evaluative Uncertainty and Permissible Preference

  The Philosophical Review · 2025-01-01 · 3 citations

  articleOpen accessSenior author

  There has recently been an explosion of interest in rational and moral choice under evaluative uncertainty—uncertainty about values or reasons. However, the dominant views on such choice have at least three major problems: they are overly demanding, they are incompatible with supererogation, and they cannot be applied to agents with credence in indeterminate evaluative theories. The authors propose a unified view that solves all these problems. According to this view, permissible options maximize expected utility relative to permissible preferences, and different kinds of permissibility for options correspond to different kinds of permissibility for preferences. Thus, rationally permissible options maximize expected utility relative to rationally permissible preferences, and morally permissible options maximize expected utility relative to morally permissible preferences. The authors argue that this view has more plausible implications than its rivals not only under evaluative uncertainty but also under ordinary uncertainty.
