Realism about Moral Deference

Open access
Farley, R. M., Southwestern Philosophical Society·2025·Southwest Philosophy Review

Abstract

Even when your informant is a trustworthy and reliable friend—rather than, say, a stranger on the bus—it doesn’t seem like you should take your moral marching orders from others. And yet, when the subject is baseball scores or directions to the train, deference to others’ testimony is taken to be uncontroversially appropriate. Thus, there is an (apparent) asymmetry between the epistemic appropriateness of deference to non-moral testimony and deference to moral testimony. The latter is widely taken to be inappropriate, the former is taken to be obviously appropriate.

TL;DR

The paper defends “realism about moral deference,” arguing that moral deference is not epistemically on par with non-moral testimony and that deference to friends, allies, and exemplars is often irrational because interesting moral beliefs are shaped by systematic bias. It claims pure moral deference can be prima facie appropriate when speakers testify against their interests, as in three cases.

Key findings

  • Rejects both pessimism and optimism: moral deference is neither rarely/never appropriate nor usually appropriate; realism says “sometimes yes, often no, and it all depends on the circumstances.”
  • Deference to friends, allies, experts, and exemplars is often irrational because interesting moral beliefs are subject to rational irrationality and in-group selection effects, giving hearers undercutting defeaters.
  • Testimony against interest defeats the presumption of bias; the paper presents three cases—Drone (Glenn Greenwald), Priest (Father Brown), and Exxon2 (Steve the lobbyist)—where pure moral deference seems prima facie appropriate and may transmit knowledge.
  • Upholds the asymmetry thesis: moral testimony should be treated with suspicion, unlike non-moral testimony, but pessimism is too strong because testimony against interest is not exactly rare.

Methods

  • Philosophical/conceptual argument in moral epistemology; no empirical data or sample.
  • Engages the optimist/pessimist literature (e.g., Fileva, Sliwa, McShane, Enoch, Jones, Wiland) and uses hypothetical cases to motivate and test intuitions.
  • Main analysis identifies rational irrationality and selection effects as defeaters for moral deference, then argues testimony against interest provides a defeater-defeater.

Limitations

  • The paper states no limitations.
  • Evident from the text: the argument relies on hypothetical cases and intuitive judgments rather than empirical evidence about bias or deference.
  • Evident from the text: the author assumes pure moral testimony exists for argument’s sake despite being skeptical, and focuses on epistemic merits while bracketing moral or prudential reasons for deference.

    In most examples used by optimists to motivate their view, deference is irrational because hearers have clear defeaters for the moral assertions made by their friends and allies.

    Our strong belief preferences (biases) about controversial moral matters frequently make it instrumentally rational for us to form interesting moral beliefs in epistemically irrational ways.

    “According to this account of moral and political belief formation, popularized by Bryan Caplan (2008), our strong belief preferences (i.e., biases) about controversial moral matters frequently make it instrumentally rational for us to form interesting moral beliefs in epistemically irrational ways.”

    The most convincing cases of appropriate moral deference are those in which speakers assert interesting moral propositions that run contrary to their known biases.

    In the Drone case, it seems appropriate to defer to Greenwald.

    “Thus, even if you, the hearer, don't get any new factual information from Greenwald or hear him make any arguments, it seems appropriate to defer to him in this case.”

    There are enough cases in which pure moral deference seems appropriate-since testimony against interest is not exactly rare-that we should not embrace pessimism.

    Both sides in the debate assume that the debate is about deference to pure moral testimony; i.e., cases in which a hearer defers to a speaker exclusively based on the latter's testimony.

  • The authors state this as an assumption.

    In ordinary cases, beliefs based on testimony are epistemically innocent until proven guilty (Reidian non-reductionism).

    “Here I just take for granted, as do the nearly all the philosophers writing about moral testimony, a form of Reidian non-reductionism; i.e., that in ordinary cases, beliefs based on testimony are epistemically innocent until proven guilty.”
  • The authors state this as an assumption.

    Moral testimony can be pure (or something thereabouts) and sometimes people form beliefs based on such testimony.

    “Thus, I take for granted that moral testimony can be pure (or something thereabouts) and that sometimes people form beliefs based on such testimony.”
  • The authors state this as an assumption.

    The hearer knows the background and identity of the speaker in the testimony-against-interest cases.

    “Although I presume the hearer knows the background and identity of the speaker, since he can identify them as testifying against their interests, ex hypothesi, he does not know the reasons the speaker has for their testimony.”

Self-check

Percentages, sums and reported differences re-computed from the paper’s own numbers.

Each contradiction between two passages listed here was confirmed by an independent check.

  • Fileva's first name differs between text and references

    Minor

    The text names the cited author Iskra Fileva, while the corresponding reference lists Iska Fileva.

  • Huemer citation points outside the listed page range

    Minor

    The text cites page 60 of Huemer's 2015 work, but the reference list gives that work a page range of 456-467.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
