Epistemic trespassers judge matters outside their field of expertise. Trespassing is ubiquitous in this age of interdisciplinary research and recognizing this will require us to be more intellectually modest.

In this paper, we reconsider the notion of epistemic trespassing and attempt to explore possible scenarios in which it could lead to positive outcomes in scientific research and information dissemination. As we will point out, some of the significant discoveries in the history of science would not have been possible were it not for the epistemic trespassers, whose shift in paradigm changed the approach to specific issues for the better. Furthermore, we will present instances where individuals, often (...) labeled as ‘trespassers’ – those who venture into fields outside their expertise – can be considered trustworthy and reliable sources of testimony. Consequently, epistemic trespassing turned out to be essential for the advancement of science. Epistemic trespassing in our age is virtually inevitable – whether it be from a political perspective (to preserve democratic values) or due to purely practical reasons (i.e. searching for information online). There are interdisciplinary fields where a strictly negative characterization of epistemic trespassing would question their methodology since these disciplines rely on experts from various fields. For these reasons, we advocate for a more charitable approach to epistemic trespassing and greater public education to help them distinguish between correct and false information. (shrink)

Epistemic trespassers are experts who pass judgment on questions in fields where they lack expertise. What’s wrong with epistemic trespassing? I identify several limitations with a seminal analysis to isolate three desiderata on an answer to this question and motivate my own answer. An answer should explain what’s wrong in the cases that motivate inquiry into epistemic trespassing, should explain what’s wrong with epistemic trespassing even if trespassers do not acknowledge their trespassing, (...) and these explanations should not be independent of the fact that epistemic trespassing involves expertise. I also independently motivate a fourth desideratum: this account should explain the evaluative difference between different kinds of trespassing. To satisfy these desiderata, I develop a social analysis: epistemic trespassing is wrong because it is an abuse of expert authority that neglects novice vulnerabilities. (shrink)

According to Macklin & Natanson (2019), one reason unusual practices can be misidentified as usual care is that “instead of using pertinent, accurate information describing usual care, investigators may rely on the opinion of ‘experts’ in the field, whose information may be out of date or otherwise inaccurate." We find Macklin & Natanson’s insights about misattributed expertise crucial, and suggest their discussion can be elucidated further by characterizing it in the context of Ballantyne (2018)’s recent exploration of what he calls (...) epistemic trespassing. What insights can be drawn from this characterization? In this commentary, we highlight two. First, the characterization elucidates the serious consequences that can result from epistemic trespassing. Second, the characterization of Macklin & Natanson’s cases as instances of epistemic trespassing offers us a potential roadmap for overcoming some of the problems the authors identify. (shrink)

The world is abuzz with experts who can help us in domains where we understand too little to help ourselves. But sometimes experts in one domain carry their privileged status into domains outside their specialization, where they give advice or otherwise presume to speak authoritatively. Ballantyne calls these boundary crossings “epistemic trespassing” and argues that they often violate epistemic norms. In the few cases where traveling in other domains is permissible, Ballantyne suggests there should be regulative checks (...) for the experts who are crossing domain boundaries. I argue that boundary crossing is warranted more often than Ballantyne allows. And while Ballantyne argues that boundary crossing is prima facie epistemically problematic, I contend that many cases of boundary crossing are not properly instances of “trespassing,” and, therefore, raise no prima facie epistemic concerns. I further argue that identifying cases of what I call “epistemic neighborliness” bolsters Ballantyne’s project, making it easier for novices and other experts to identify epistemic trespassing along with its epistemic problems.

The term ‘epistemic trespassing’ has recently been coined to denote a person’s judgments regarding a domain where they are not epistemic experts. In this paper, I focus on expert trespassing testimony – that is, testimony by an expert in a domain of expertise other than his own. More specifically, I focus on intra-scientific trespassing testimony between scientific collaborators. By developing a number of distinctions, I argue that while intra-scientific trespassing testimony may seriously hamper scientific (...) collaboration, it does not invariably do so and may even be beneficial to it. (shrink)

The novice/expert problem is the problem of knowing which apparent expert to trust. Following Alvin Goldman’s lead, a number of philosophers have developed criteria that novices can use to distinguish more from less trustworthy experts. While the criteria the philosophers have identified are indeed useful in guiding expert choice, I argue, they can’t do the work that Goldman and his successors want from them: avoid a kind of testimonial scepticism. We can’t deploy them in the way needed to avoid such (...) scepticism, because it would take genuine expertise to do so. I argue that attempts to deploy them in this sort of deep way involve a kind of transgression akin to, and at least as unreliable as, epistemic trespassing. We should give up trying to solve the novice/expert problem and instead promote better epistemic trust. (shrink)

Scientific expert testimony is crucial to public deliberation, but it is associated with many pitfalls. This article identifies one—namely, expert trespassing testimony—which may be characterized, crudely, as the phenomenon of experts testifying outside their domain of expertise. My agenda is to provide a more precise characterization of this phenomenon and consider its ramifications for the role of science in society. I argue that expert trespassing testimony is both epistemically problematic and morally problematic. Specifically, I will argue that scientific (...) experts are subject to a particular obligation. Roughly, this is the obligation to qualify their assertions when speaking outside their domain of scientific expertise in certain contexts. Thus, I argue that scientists who possess expert knowledge are confronted with hard questions about when and how to testify and, therefore, that being a scientific expert comes with great responsibility. Consequently, I provide a concrete “expert guideline” according to which scientific experts, in certain contexts, face an obligation to qualify their assertions when speaking outside their domain of expertise. Furthermore, I consider a number of the conditions in which the guideline is waived or overridden. On this basis, I consider the broader aspects of the roles of scientific experts in a society with a high division of cognitive labor that calls for trust in scientific expert testimony. (shrink)

Epistemic trespassers have competence in one field but pass judgment on matters in other fields where they lack competence. I examine philosophical questions related to epistemic trespassing by expert witnesses in courtroom trials and argue for the following positions. Expert witnesses are required to avoid epistemic trespassing. When testifying as an expert witness, merely qualifying one’s statements to indicate that one is not speaking as an expert is insufficient to avoid epistemic trespassing. Judges, (...) litigators, and jurors can often recognize epistemic trespassing by examining a purported expert’s credentials and track record. Judges should not permit recognizable epistemic trespassers to testify as expert witnesses. Litigators should seek to expose recognizable epistemic trespassers during cross-examination. Jurors should treat recognizable instances of epistemic trespassing as a reason to downgrade the testimony of epistemic trespassers. (shrink)

“One who elects to serve mankind by taking the law into his own hands thereby demonstrates his conviction that his own ability to determine policy is superior to democratic decision making. [Defendants’] professed unselfish motivation, rather than a justification, actually identifies a form of arrogance which organized society cannot tolerate.” Those were the words of Justice Harris L. Hartz at the sentencing hearing of three nuns convicted of trespassing and vandalizing government property to demonstrate against U.S. foreign policy. Citizens (...) engaging in civil disobedience are indeed at times accused of being arrogant because they apparently think their own political judgment is superior to that of the democratic majority. This paper examines and evaluates the claim that dissenters are epistemically arrogant. Contrary to the dominant viewpoint in the literature, I argue that epistemic arrogance involves inflating the epistemic worth of one’s view. Indeed, the most plausible charge against civil dissenters consists of two claims: (A) civil dissenters have a higher degree of rational certainty in P than is warranted, and (B) civil dissenters use a method of expression that requires a higher level of rational certainty than is warranted in the propositions that their political view is right and the injustice they fight is substantial. I argue that civil disobedience does not necessarily involve epistemic arrogance. Whether an act of civil disobedience evinces epistemic arrogance has to be determined on a case-by-case basis depending on the extent to which each dissenter lives up to (A) and (B). (shrink)

Epistemic trespassing, science denial, refusal to guard against bias, mishandling higher-order evidence, and the development of vice are troubling intellectual behaviors. In this paper, I advance work done by psychologists on moral self-licensing to show how all of these behaviors can be explained in terms of a parallel phenomenon of epistemic self-licensing. The paper situates this discussion at the intersection of three major epistemological projects: epistemic explanation and intervention (the project of explaining troubling intellectual phenomena in (...) the hopes of deriving ameliorative strategies), hostile epistemology (the study of how intellectual vulnerabilities might be exploited), and the promise of higher- order evidence (the hope that higher-order evidence leads to epistemic improvement). Analyzing epistemic licensing allows us to explain and offer modest interventions aimed at mitigating these behaviors, while illuminating exploitable vulnerabilities and tempering optimism about the promise of higher-order evidence. -/- .

Novelty—the value of saying something new—appears to be a good-making feature of a philosophical contribution. Beyond this, however, novelty functions as a metric of success. This paper challenges the presumption and expectation that a successful philosophical contribution will be a novel one. As I show, the pursuit of novelty is neither as desirable nor as feasible as it might initially seem.

This paper studies the lessons of principled anti-corruption experts who dared to fulfill their duty of justice in highly corrupt societies, through the true story of Ngozi Okonjo-Iweala, the former Finance Minister of Nigeria. My thesis is that when principled anti-corruption experts are epistemic trespassers, they show moral incompetence. Okonjo-Iweala shows moral incompetence in two ways: she misread the opposition to her strategies and misled other honest reformers. Both actions bungled her efforts to eradicate corruption inasmuch as they hindered (...) the possibility of finding successful anti-corruption policies. Okonjo-Iweala’s moral incompetence is, I argue, the result of her epistemic trespassing that led her to act like an expert in an environment where she was not. I conclude that, in highly corrupt societies, principled anti-corruption experts should embrace moral humility, stop thinking that they are experts, and act more like students, asking questions and not rushing to think that they understand the answers.

It is widely accepted that consent is a normative power. For instance, consent can make an impermissible act permissible. In the words of Heidi Hurd, it “turns a trespass into a dinner party... an invasion of privacy into an intimate moment.” In this chapter, I argue against the assumption that consent has such robust powers for moral transformation. In particular, I argue that there is a wide range of sex that harms or wrongs victims despite being consensual. Moreover, these cases (...) are not limited to those where con- sent is vitiated by background conditions. I start by calling this category of consensual sex Bad Sex. I then distinguish subspecies of this category, including psychological pressure, social coercion, and epistemically unsafe sex. I end by responding to an objection on which we should treat at least some subspecies of Bad Sex as rape. Though this alternative proposal is often motivated by ameliorative and strategic considerations, I argue that such considerations actually count against collapsing the categories of Bad Sex and rape.

Seventeenth-century optics naturalizes the eye while estranging the mind from objects. A mere screen, on which rests a blurry array of light stains, the eye no longer furnishes the observer with genuine re-presentations of visible objects. The intellect is thus compelled to decipher flat images of no inherent epistemic value, accidental effects of a purely causal process, as vague, reversed reflections of wholly independent objects. Reflecting on and trespassing the boundaries between natural and artificial, orderly and disorderly, this (...) optical paradox is a Baroque phenomenon; and it is the origin of Descartes’ celebrated doubt---whether we know anything at all.

Since at least the 1970s, one of the stock standard tools in the animal protection movement’s arsenal has been illegal entry into factory farms and animal research facilities. This activity has been followed by the publication of images and footage captured inside those otherwise socially invisible places. This activity presents a conundrum: trespass is illegal and it is an apparent violation of private property rights. In this paper we argue that trespass onto private property can be justified as an act (...) of civil disobedience. We look at one particular type of justification: the use of information gathered through trespass in public policy formation. We then animate this analysis both with an historical overview of the effects of sharing information about animal agriculture, and with a specific case study of trespass undertaken recently.

Dramatic changes or revolutions in a field of science are often made by outsiders or 'trespassers,' who are not limited by the established, 'expert' approaches. Each essay in this diverse collection shows the fruits of intellectual trespassing and poaching among fields such as economics, Kantian ethics, Platonic philosophy, category theory, double-entry accounting, arbitrage, algebraic logic, series-parallel duality, and financial arithmetic.

Opening with the author's attempt to sneak herself and her father into a conference attended by the planet's great scientific thinkers (including Brian Greene, Max Tegmark, and coiner of the term "black hole" John Wheeler), Trespassing on Einstein's Lawn takes readers on an exhilarating and memorable journey to the mysterious heart of the universe.

In this paper, I present an objection to the reflective equilibrium method based on land purchases and trespassing. I then propose a solution, which involves a change to how we regard the method.

This essay theorizes how the enforcement of universal norms contributes to the solidification of sovereign rule. It does so by analyzing John Locke’s argument for the founding of the commonwealth as it emerges from his notion of universal crime in the Second Treatise of Government. Previous studies of punishment in the state of nature have not accounted for Locke’s notion of universal crime which pivots on the role of mankind as the subject of natural law. I argue that the dilemmas (...) specific to enforcing the natural law against “trespasses against the whole species” drive the founding of sovereign government. Reconstructing Locke’s argument on private property in light of universal criminality, the essay shows how the introduction of money in the state of nature destabilizes the normative relationship between the self and humanity. Accordingly, the failures of enforcing the natural law require the partitioning of mankind into separate peoples under distinct sovereign governments. This analysis theorizes the creation of sovereign rule as part of the political productivity of Locke’s notion of universal crime and reflects on an explicitly political, rather than normative, theory of “humanity.”.

In this article, from the 2009 Oxford University Press collection Epistemic Value, I criticize existing accounts of epistemic normativity by Alston, Goldman, and Sosa, and then offer a new view.

Epistemic akrasia arises when one holds a belief even though one judges it to be irrational or unjustified. While there is some debate about whether epistemic akrasia is possible, this paper will assume for the sake of argument that it is in order to consider whether it can be rational. The paper will show that it can. More precisely, cases can arise in which both the belief one judges to be irrational and one’s judgment of it are epistemically (...) rational in the sense that both are supported by sufficient evidence.

It is a received view of the post-Fregean predicate logic that a universal statement has no existential import and thus does not entail its particular (existential) counterpart. This paper takes issue with the view by discussing the trespasser case, which has widely been employed for supporting the view. The trespasser case in fact involves a shift of context. Properly understood, the case provides no support for the received view but rather suggests that we rethink the ‘quantity view’ of the existential (...) import of quantifiers. (shrink)

The purpose of this article is to identify a limit to the appropriate application of property law to the use and storage of bodily material. I argue here that property law ought to be limited to protecting ‘contingent rights’ and that recent cases where property rights have been recognised in semen represent the application of property law beyond this limit. I also suggest how the law ought to develop in order to avoid the overextensive use of property law.

We may succeed in the fulfillment of our desires but still fail to properly own our practical life, perhaps because we acted as addicts, driven by desires that are alien to our will, or as “wantons,” satisfying the desires that we simply happen to have (Frankfurt, 1988). May we equally fail to own the outcomes of our epistemic life? If so, how may we attain epistemic ownership over it? This paper explores the structural parallelism between practical and (...) class='Hi'>epistemic rationality, building on Williamson’s (2002) suggestion that we should commence with successful performances as the foundation for both domains, be it action or knowledge. By highlighting the limitations of higher-order regulative approaches in epistemology, exemplified by Sosa (2007, 2011, 2015, 2021), the paper introduces a form of teleological epistemic constitutivism inspired by Velleman (2000, 2009). The proposal is that epistemic ownership is not attained in the mere pursuit of truth or knowledge, but requires furthermore a struggle to understand what we know. (shrink)

Lisa Bortolotti argues that some irrational beliefs are epistemically innocent and deliver significant epistemic benefits that could not be easily attained otherwise. While the benefits of the irrational belief may not outweigh the costs, epistemic innocence helps to clarify the epistemic and psychological effects of irrational beliefs on agency.

Epistemic modal operators give rise to something very like, but also very unlike, Moore's paradox. I set out the puzzling phenomena, explain why a standard relational semantics for these operators cannot handle them, and recommend an alternative semantics. A pragmatics appropriate to the semantics is developed and interactions between the semantics, the pragmatics, and the definition of consequence are investigated. The semantics is then extended to probability operators. Some problems and prospects for probabilistic representations of content and context are (...) explored. (shrink)

In Epistemic injustice, Miranda Fricker makes a tremendous contribution to theorizing the intersection of social epistemology with theories of justice. Theories of justice often take as their object of assessment either interpersonal transactions (specific exchanges between persons) or particular institutions. They may also take a more comprehensive perspective in assessing systems of institutions. This systemic perspective may enable control of the cumulative effects of millions of individual transactions that cannot be controlled at the individual or institutional levels. This is (...) true not only with respect to the overall distribution of such goods as income and wealth, but also with respect to the goods of testimonial and hermeneutical justice. Cognitive biases that may be difficult for even epistemically virtuous individuals to correct on their own may be more susceptible to correction if we focus on the principles that should govern our systems of testimonial gathering and assessment. Hence, while Fricker’s focus on individual epistemic virtue is important, we also need to consider what epistemic justice as a virtue of social systems would require. My paper will indicate some directions forward on this front, focusing on the need for integration of diverse institutions and persons engaged in inquiry. (shrink)

An important issue in epistemology concerns the source of epistemic normativity. Epistemic consequentialism maintains that epistemic norms are genuine norms in virtue of the way in which they are conducive to epistemic value, whatever epistemic value may be. So, for example, the epistemic consequentialist might say that it is a norm that beliefs should be consistent, in that holding consistent beliefs is the best way to achieve the epistemic value of accuracy. Thus (...) class='Hi'>epistemic consequentialism is structurally similar to the family of consequentialist views in ethics. Recently, philosophers from both formal epistemology and traditional epistemology have shown interest in such a view. In formal epistemology, there has been particular interest in thinking of epistemology as a kind of decision theory where instead of maximizing expected utility one maximizes expected epistemic utility. In traditional epistemology, there has been particular interest in various forms of reliabilism about justification and whether such views are analogous to—and so face similar problems to—versions of consequentialism in ethics. This volume presents some of the most recent work on these topics as well as others related to epistemic consequentialism, by authors that are sympathetic to the view and those who are critical of it.

This paper argues that the current discourse on epistemic injustice in social epistemology itself perpetuates epistemic injustice, namely hermeneutic injustice with regards to class and classism. The main reason is that debates on epistemic injustice have foremost focussed on issues related to gender, race, and disability while mostly ignoring class issues. I suggest that this is due to (largely unwarranted) fears about looming class reductionism. More importantly, this is omission is not innocuous, but problematic insofar as it (...) has an unlikely ally in neoliberal propaganda which features as one main goal stifling class consciousness. While this “allyship” is unwitting, this presents grounds for the discourse of epistemic injustice to consider re-centring class issues and classism. (shrink)

Introduction As the title indicates, the chief focus of this book is epistemic justification. But just what is epistemic justification and what is its place ...

The Federalist, justifying the Electoral College to elect the president, claimed that a small group of more informed individuals would make a better decision than the general mass. But the Condorcet Jury Theorem tells us that the more independent, better-than-random voters there are, the more likely it will be that the majority among them will be correct. The question thus arises as to how much better, on average, members of the smaller group would have to be to compensate for the (...) epistemic costs of making decisions on the basis of that many fewer votes. This question is explored in the contexts of referendum democracy, delegate-style representative democracy, and trustee-style representative democracy. (shrink)

La teoría democrática rara vez se ajusta a las prácticas democráticas y las fluctuaciones de la opinión pública rara vez coincide con la cobertura de ese mismo actor político en los medios de comunicación. En septiembre de 2010, el partido anti-inmigración sueco, los Sweden Democrats (SD), superaron el límite electoral necesario para participar en el parlamento de Suecia y su popularidad no ha cesado de crecer. En este artículo, analizamos el efecto que tiene la exposición mediática en las fluctuaciones de (...) las encuestas de opinión sobre los partidos políticos, o el llamado efecto mediático. Nuestros resultados muestran que el efecto mediático es más intenso en el caso del SD que en el de otros partidos parlamentarios. La exposición mediática repercute en ocasiones, pero no en el mismo grado ni necesariamente en el mismo momento. (shrink)
