Research in the psychology of deception detection implies that Fricker, in making her case for reductionism in the epistemology of testimony, overestimates both the epistemic demerits of the antireductionist policy of trusting speakers blindly and the epistemic merits of the reductionist policy of monitoring speakers for trustworthiness: folk psychological prejudices to the contrary notwithstanding, it turns out that monitoring is on a par (in terms both of the reliability of the process and of the sensitivity of the beliefs (...) that it produces) with blind trust. The consequence is that while (a version of) Fricker’s argument for the necessity of a reduction succeeds, her argument for the availability of reductions fails. This does not, however, condemn us to endorse standard pessimistic reductionism, according to which there is no testimonial knowledge, for recent research concerning the methods used by subjects to discover deception in non-laboratory settings suggests that only a more moderate form of pessimism is in order.

The recent emergence of machine-manipulated media raises an important societal question: How can we know whether a video that we watch is real or fake? In two online studies with 15,016 participants, we present authentic videos and deepfakes and ask participants to identify which is which. We compare the performance of ordinary human observers with the leading computer vision deepfake detection model and find them similarly accurate, while making different kinds of mistakes. Together, participants with access to the model’s (...) prediction are more accurate than either alone, but inaccurate model predictions often decrease participants’ accuracy. To probe the relative strengths and weaknesses of humans and machines as detectors of deepfakes, we examine human and machine performance across video-level features, and we evaluate the impact of preregistered randomized interventions on deepfake detection. We find that manipulations designed to disrupt visual processing of faces hinder human participants’ performance while mostly not affecting the model’s performance, suggesting a role for specialized cognitive capacities in explaining human deepfake detection performance. -/- .

Social participation requires certain abilities: communication with other members of society; social understanding which enables planning ahead and dealing with novel circumstances; and a theory of mind which makes it possible to anticipate the mental state of another. In childhood play we learn how to pretend, how to put ourselves in the minds of others, how to imagine what others are thinking and how to attribute false beliefs to them. Without this ability we would be unable to deceive and detect (...) deception in the actions of others, and our ability to interact within our social group would be greatly impaired. In this paper I claim that the capacity for deception is necessary for a theory of mind, and a theory of mind is necessary for complex social interaction. (shrink)

Abstract: Cheating behaviors have been construed as a continuing and somewhat vexing issue for academic institutions as they increasingly conduct educational processes online and impose metrics on instructional evaluation. Research, development, and implementation initiatives on cheating detection have gained new dimensions in the advent of artificial intelligence (AI) applications; they have also engendered special challenges in terms of their social, ethical, and cultural implications. An assortment of commercial cheating–detection systems have been injected into educational contexts with little input (...) on the part of relevant stakeholders. This paper expands several specific cases of how systems for the detection of cheating have recently been implemented in higher education institutions in the US and UK. It investigates how such vehicles as wearable technologies, eye scanning, and keystroke capturing are being used to collect the data used for anti-cheating initiatives, often involving systems that have not gone through rigorous testing and evaluation for their validity and potential educational impacts. The paper discusses accountability- and policy-related issues concerning the outsourcing of cheating detection in institutional settings in the light of these emerging technological practices as well as student resistance against the systems involved. The cheating-detection practices can place students in a disempowered, asymmetrical position that is often at substantial variance with their cultural backgrounds. (shrink)

Drawing on both empirical evidence and evolutionary considerations, Sperber et al. argue that humans have a suite of evolved mechanisms for . On their view, vigilance plays a crucial role in ensuring the reliability and hence the evolutionary stability of communication. This article responds to their argument for vigilance, drawing on additional empirical evidence (from deception detection research) and evolutionary considerations (from animal signalling research) to defend a more optimistic, quasi-Reidian view of communication. On this alternative view, the (...) lion's share of the responsibility for explaining the reliability of testimony falls not to the vigilance of receivers but rather to the honesty of communicators, implying that vigilance does not play a major role in explaining the evolutionary stability of communication.

It is often suggested that we are equipped with a set of cognitive tools that help us to filter out unreliable testimony. But are these tools effective? I answer this question in two steps. Firstly, I argue that they are not real-time effective. The process of filtering, which takes place simultaneously with or right after language comprehension, does not prevent a particular hearer on a particular occasion from forming beliefs based on false testimony. Secondly, I argue that they are long-term (...) effective. Some hearers sometimes detect false testimony, which increases speakers’ incentives for honesty and stabilizes the practice of human communication in which deception is risky and costly. In short, filtering prevents us from forming a large number of beliefs based on false testimony, not by turning each of us into a high-functioning polygraph but by turning the social environment of human communication into one in which such polygraphs are not required. Finally, I argue that these considerations support strong anti-reductionism about testimonial entitlement. (shrink)

The detection of hate speech and fake news in political discourse is at the same time a crucial necessity for democratic societies and a challenge for several areas of study. However, most of the studies have focused on what is explicitly stated: false article information, language that expresses hatred, derogatory expressions. This paper argues that the explicit dimension of manipulation is only one – and the least problematic – of the risks of political discourse. The language of the unsaid (...) is much more dangerous and incomparably more difficult to detect, hidden in different types of fallacies and inappropriate uses of emotive language. Through a threefold coding scheme based on the instruments of argumentation theory and pragmatics, a corpus of argumentative tweets published by 4 politicians (Matteo Salvini, Donald Trump, Jair Bolsonaro, and Joseph Biden) within 6 months from their taking office (corresponding to the official end of their election campaign) is analyzed, detecting the types of argument, the fallacies, and the uses and misuses of “emotive words.” This coding results in the argumentation profiles of the speakers, which are compared statistically to show their different implicit strategies and deceptive tactics.

People commonly believe that any form of deception, no matter how innocuous it is and no matter whether the deceiving person intended it otherwise, is always morally wrong. In this paper, I will argue that deceiving in real-time is morally distinguishable from deceiving on-line because online actions aren’t as fine-grained as actions occurring in real-time. Our failure to detect the fine-grained characteristics of another avatar leads us to believe that that avatar intended to do a moral harm. Openly deceiving (...) someone on Facebook or Twitter is not a way to build wholesome virtual friendships but to destroy them. This paper will show how the traditional understanding of the doing / allowing distinction fails to apply in cyberspace. (shrink)

Deepfakes pose a multi-faceted threat to the acquisition of knowledge. It is widely hoped that technological solutions—in the form of artificially intelligent systems for detecting deepfakes—will help to address this threat. I argue that the prospects for purely technological solutions to the problem of deepfakes are dim. Especially given the evolving nature of the threat, technological solutions cannot be expected to prevent deception at the hands of deepfakes, or to preserve the authority of video footage. Moreover, the success of (...) such technologies depends on institutional trust that is in short supply. Finally, outsourcing the discrimination between the real and the fake to automated, largely opaque systems runs the risk of undermining epistemic autonomy. (shrink)

The standard view in social science and philosophy is that lying does not require the liar’s assertion to be false, only that the liar believes it to be false. We conducted three experiments to test whether lying requires falsity. Overall, the results suggest that it does. We discuss some implications for social scientists working on social judgments, research on lie detection, and public moral discourse.

I offer a new argument for the elimination of ‘beliefs’ from cognitive science based on Wimsatt’s concept of robustness and a related concept of fragility. Theoretical entities are robust if multiple independent means of measurement produce invariant results in detecting them. Theoretical entities are fragile when multiple independent means of detecting them produce highly variant results. I argue that sufficiently fragile theoretical entities do not exist. Recent studies in psychology show radical variance between what self-report and non-verbal behaviour indicate about (...) participants’ beliefs. This is evidence that ‘belief’ is fragile, and is thus a strong candidate for elimination. 1 Introduction2 Robustness and Fragility2.1 A historical example of robustness2.2 Fragility and elimination3 The Received View4 Evidence for the Fragility of Belief4.1 Contamination and fragility4.2 Implicit association tests and fragility5 Attempts to Preserve the Belief Category for Cognitive Science5.1 Beliefs and aliefs5.2 Contradictory beliefs5.3 In-between beliefs and the unity assumption5.4 Belief sub-classes5.5 Self-deception6 Alternative Mental States7 Conclusion.

The paper focuses on the analysis of conspiracy beliefs and conspiracy theories by taking into consideration some of the major contributions about the topic presently provided by several disciplines. A definition is given that helps illustrate the most prominent features of these beliefs, namely monological bias, logical and conceptual fallacies, dispositional influence and pseudorationality. Other important psychological preconditions are also provided (such as, among others, credulity, hypersensitive agency detection devices and proneness to self-deception), but, as the paper argues, (...) they are features shared to a greater or lesser extent with other belief systems, like radical political ideologies and religious fundamentalisms. As a result, it is suggested that a more proper understanding of the phenomenon is attainable by approaches combining psychological data with the analysis of groups and sociopolitical dynamics. Exceptional contingencies and shifts in power distribution among group/social actors seem to be the most influential factors that explain formation, spread and salience of this kind of beliefs.

I argue that Kant took from Moses Mendelssohn the idea of a distinction between geometry of morals and a practical ethic. He was drastically misunderstood by his followers precisely on this point. He had learned from the sceptics and the Jansenists the lesson that men are prompted to act by deceptive ends, and he was aware that human actions are also empirical phenomena, where laws like the laws of Nature may be detected. His practical ethics made room for judgment as (...) a holistic procedure for assessing the salience of relevant moral qualities in one given situation; this procedure yields the same results as the geometry of morals does for abstract cases, but does so immediately and without balancing conflicting duties with each other, since what makes for the salient quality of a situation is perceived from the very beginning.

In this entry, I seek to show the interdependence of questions about self-deception in philosophy of mind, psychology, and ethics. I taxonomize solutions to the paradoxes of self-deception, present possible psychological mechanisms behind it, and highlight how different approaches to the philosophy of mind and psychology will affect how we answer important ethical questions. Is self-deception conducive to happiness? How does self-deception affect responsibility? Is there something intrinsically wrong with self-deception? The entry, on the one (...) hand, is a tour of the literature; on the other, it is a case for more work that crosses traditional sub-disciplinary boundaries. (shrink)

Altruistic deception (or the telling of “white lies”) is common in humans. Does it also exist in non-human animals? On some definitions of deception, altruistic deception is impossible by definition, whereas others make it too easy by counting useful-but-ambiguous information as deceptive. I argue for a definition that makes altruistic deception possible in principle without trivializing it. On my proposal, deception requires the strategic exploitation of a receiver by a sender, where “exploitation” implies that the (...) sender elicits a behaviour in the receiver that is beneficial in a different type of situation and is expressed only because the signal raises the probability, from the receiver’s standpoint, of that type of situation. I then offer an example of a real signal that is deceptive in this sense, and yet potentially altruistic (and certainly cooperative): the purr call of the pied babbler. Fledglings associate purr calls with food, and adults exploit this learned association, in the absence of food, to lead fledglings away from predators following an alarm call. I conclude by considering why altruistic deception is apparently so rare in non-human animals. (shrink)

Deception has recently received a significant amount of attention. One of main reasons is that it lies at the intersection of various areas of research, such as the evolution of cooperation, animal communication, ethics or epistemology. This essay focuses on the biological approach to deception and argues that standard definitions put forward by most biologists and philosophers are inadequate. We provide a functional account of deception which solves the problems of extant accounts in virtue of two characteristics: (...) deceptive states have the function of causing a misinformative states and they do not necessarily provide direct benefits to the deceivers and losses to the targets.

Self-deception is typically considered epistemically irrational, for it involves holding certain doxastic attitudes against strong counter-evidence. Pragmatic encroachment about epistemic rationality says that whether it is epistemically rational to believe, withhold belief or disbelieve something can depend on perceived practical factors of one’s situation. In this paper I argue that some cases of self-deception satisfy what pragmatic encroachment considers sufficient conditions for epistemic rationality. As a result, we face the following dilemma: either we revise the received view about (...) self-deception or we deny pragmatic encroachment on epistemic rationality. I suggest that the dilemma can be solved if we pay close attention to the distinction between ideal and bounded rationality. I argue that the problematic cases fail to meet standards of ideal rationality but exemplify bounded rationality. The solution preserves pragmatic encroachment on bounded rationality, but denies it on ideal rationality. (shrink)

Regarding the appropriateness of deception in clinical practice, two (apparently conflicting) claims are often emphasised. First, that ‘clinicians should not deceive their patients.’ Second, that deception is sometimes ‘in a patient’s best interest.’ Recently, Hardman has worked towards resolving this conflict by exploring ways in which deceptive and non-deceptive practices extend beyond consideration of patients’ beliefs. In short, some practices only seem deceptive because of the (common) assumption that non-deceptive care is solely aimed at fostering true beliefs. Non-deceptive (...) care, however, relates to patients’ non-doxastic attitudes in important ways as well. As such, Hardman suggests that by focusing on belief alone, we sometimes misidentify non-deceptive care as ‘deceptive’. Further, once we consider patients’ beliefs and non-doxastic attitudes, identifying cases of deception becomes more difficult than it may seem. In this essay, I argue that Hardman’s reasoning contains at least three serious flaws. First, his account of deception is underdeveloped, as it does not state whether deception must be intentional. The problem is that if intention is not required, absurd results follow. Alternatively, if intention is required, then identifying cases of deception will be much easier (in principle) than Hardman suggests. Second, Hardman mischaracterises the ‘inverse’ of deceptive care. Doing so leads to the mistaken conclusion that common conceptions of non-deceptive care are unjustifiably narrow. Third, Hardman fails to adequately separate questions about deception from questions about normativity. By addressing these issues, however, we can preserve some of Hardman’s most important insights, although in a much simpler, more principled way. (shrink)

In the philosophical literature, self-deception is mainly approached through the analysis of paradoxes. Yet, it is agreed that self-deception is motivated by protection from distress. In this paper, we argue, with the help of findings from cognitive neuroscience and psychology, that self-deception is a type of affective coping. First, we criticize the main solutions to the paradoxes of self-deception. We then present a new approach to self-deception. Self-deception, we argue, involves three appraisals of the (...) distressing evidence: (a) appraisal of the strength of evidence as uncertain, (b) low coping potential and (c) negative anticipation along the lines of Damasio’s somatic marker hypothesis. At the same time, desire impacts the treatment of flattering evidence via dopamine. Our main proposal is that self-deception involves emotional mechanisms provoking a preference for immediate reward despite possible long-term negative repercussions. In the last part, we use this emotional model to revisit the philosophical paradoxes. (shrink)

In this paper, I defend the view that self-deception is a moral failure. Instead of saying that self-deception is bad because it undermines our moral character or leads to morally deleterious consequences, as has been argued by Butler, Kant, Smith, and others, I argue the distinctive badness of self-deception lies in the tragic relationship that it bears to our own values. On the one hand, self-deception is motivated by what we value. On the other hand, it (...) prevents us from valuing those things properly. I argue that we owe it ourselves to take seriously our own values, by striving to properly value them. This gives us both prudential and moral reasons to avoid self-deception. (shrink)

In this paper I will use sex by deception as a case study for highlighting some of the most tricky concepts around sexuality and moral psychology, including rape, consensual sex, sexual rights, sexual autonomy, sexual individuality, and disrespectful sex. I begin with a discussion of morally wrong sex as rooted in the breach of five sexual liberty rights that are derived from our fundamental human liberty rights: sexual self-possession, sexual autonomy, sexual individuality, sexual dignity and sexual privacy. I then (...) argue (against the standard interpretation) that experimental findings in moral psychology show that the principle of respect for persons—a principle that grounds our human liberty rights—drives our intuitive moral judgments. In light of this discussion, I examine a puzzle about sex by deception—a puzzle which at first may seem to compel us to define 'rape' strictly in terms of force rather than sexual autonomy. I proceed by presenting an argument against the view that, as a rule, sex by deception undermines consent—a position held by prominent thinkers such as Philippe Patry (2001), Onora O’Neill (2003), Rubenfeld (2012), Tom Dougherty (2013a, 2013b), Joyce M. Short (2013), and Danielle Bromwich and Joseph Millum (2013, 2018). As we will see, sex following deception to increase your chances does not always constitute rape. Lying about your age, education, job, family background, marital status, or interest in a relationship, for example, does not make your sex partner incapable of consenting, which is to say that sex by deception need not be rape. I even go so far as to say that sex with another person that is facilitated by withholding information about having a venereal disease shouldn't be classified as rape. Although sex by deception doesn't compromise consent, it nonetheless violates the principle of respect for persons, not by vitiating sexual autonomy and compromising consent, but by failing to respect other sexual rights, such as our rights to sexual dignity, individuality, and privacy.

Godfrey-Smith advocates for linking deception in sender-receiver games to the existence of undermining signals. I present games in which deceptive signals can be arbitrarily frequent, without this undermining information transfer between sender and receiver.

Cooperative relations steeped in honesty and good faith are a necessity for any viable society. This is especially relevant to the police institution because the police are entrusted to promote justice and security. Despite the necessity of societal honesty and good faith, the police institution has embraced deception, dishonesty, and bad faith as tools of the trade for providing security. In fact, it seems that providing security is impossible without using deception and dishonesty during interrogations, undercover operations, pretextual (...) detentions, and other common scenarios. This presents a paradox related to the erosion of public faith in the police institution and the weakening of the police's legitimacy. -/- The book seeks to solve this puzzle by showing that many of our assumptions about policing and security are unjustified. Specifically, they are unjustified in the way many of our assumptions about security were unjustified after the 9/11 terrorist attacks, when state institutions embraced a variety of brutal rules and tactics in pursuit of perceived security enhancements. The police are likewise unjustified in their pursuit of many supposed security enhancements that rely on proactive deception, dishonesty, and bad faith. -/- There are compelling reasons to think that the police's widespread use of proactive deception and dishonesty is inconsistent with fundamental norms of political morality regarding fraud and the rule of law. Although there are times and places for such tactics in policing, those times and places should be much more limited than current practices suggest. (shrink)

My central question in this paper is how delusional beliefs are related to self-deception.

Abstract: Sarcasm is commonly used in news and detecting sarcasm in headline news is challenging for humans and thus for computers. The media regularly seem to engage sarcasm in their news headline to get the attention of people.

The aim of the study is to build a sarcasm model that detect headline news using machine and deep learning and attempt to understand how a computer learns the patterns of sarcasm. The dataset used in this study was collected from Kaggle depository. We examined 21 algorithms of machine learning and one deep learning algorithm for detecting sarcasm in headline news. The evaluation metric used in this study are Accuracy, F1-measure, Recall, Precision, and Time needed for training and evaluation. The deep learning model achieved accuracy (95.27%), recall (96.62%), precision (94.15%), F1-score (95.37%) and time needed to train the mode (400 seconds), with loss of around 0.3398. However, the algorithm of machine learning that achieved the highest F1-Score is Passive Aggressive Classifier. It was the top classier for sarcasm detection among the machine learning algorithms with accuracy (95.50%), recall (96.09 %), precision (94.30%), F1-score (95.19%) and time needed to train the mode (0.31 seconds).

A prevalent assumption among philosophers who believe that people can intentionally deceive themselves (intentionalists) is that they accomplish this by controlling what evidence they attend to. This article is concerned primarily with the evaluation of this claim, which we may call ‘attentionalism’. According to attentionalism, when one justifiably believes/suspects that not-p but wishes to make oneself believe that p, one may do this by shifting attention away from the considerations supportive of the belief that not-p and onto considerations supportive of (...) the belief that p. The details of this theory are elaborated, its theoretical importance is pointed out, and it is argued that the strategy is supposed to work by leading to the repression of one’s knowledge of the unwelcome considerations. However, I then show that the assumption that this is possible is opposed by the balance of a relevant body of empirical research, namely, the thought-suppression literature, and so intentionalism about self-deception cannot find vindication in the attentional theory.

This article discusses Du Châtelet’s challenging claim that entertaining illusions, especially illusions of being esteemed by posterity, is conducive to happiness. It does so by taking a contextualizing approach, contrasting her views with some Epicurean aspects of the views on illusions and happiness in Bernard de Fontenelle and Julien Offray de La Mettrie. I will argue for three claims: (1) Du Châtelet’s comparison between self-related illusions and illusions in the theater is vulnerable to objections deriving from some distinctions that Fontenelle’s (...) poetics draws between the role of illusions in the theater and the role of illusions in real life. (2) Examining Fontenelle’s analysis of the detrimental effects of self-related illusions indicates several respects in which Du Châtelet has underestimated the ambivalent nature of illusions.

Although Kant is one of the very few classical writers referred to in the current literature on lying, hardly any attention is paid to how his views relate to the contemporary discussion on the definition of lying. I argue that, in Kant’s account, deception is not the defining feature of lying. Furthermore, his view is able to acknowledge non-deceptive lies. Kant thus holds, I suggest, a version of what is currently labelled Intrinsic Anti-Deceptionism. In his specific version of such (...) a view, furthermore, dishonesty is the distinctive feature of lying. Finally, I highlight the important methodological differences between Kant’s normatively minded account and the primarily descriptive contemporary discussion, with regard to the role of intuitions and definitions in building a moral theory: In contrast to the current debate, Kant does not rely on intuitions, but defines lying in terms of the obligation it violates.

Stubborn belief, like self-deception, is a species of motivated irrationality. The nature of stubborn belief, however, has not been investigated by philosophers, and it is something that poses a challenge to some prominent accounts of self-deception.

The recognition of this phenomenon should force an amendment in (...) this account, and should also make a Mele-style deflationist think more carefully about the kinds of motivational factors operating in self-deception.

The deceptive clues in the impossible puzzle film confirm the viewer’s internal expectations and allow retrospective attributing.

In this article I discuss and evaluate the selectivity problem as a problem put forward by Bermudez (1997, 2000) against anti-intentionalist accounts of self-deception. I argue that the selectivity problem can be raised even against intentionalist accounts, which reveals the too demanding constraint that the problem puts on the adequacy of a psychological explanation of action. Finally I try to accommodate the intuitions that support the cogency of the selectivity problem using the resources from the framework provided by an (...) anti-intentionalist account of self-deception.

The suppression thesis is the theological claim that theistic non-belief results from culpable mistreatment of one’s knowledge of God or one’s evidence for God. The thesis is a traditional one but unpopular today. This article examines whether it can gain new credibility from the philosophy of self-deception and from the cognitive science of religion. The thesis is analysed in terms of the intentionalist and the non-intentionalist model of self-deception. The first proposed model views non-belief as intentional suppression of (...) one’s implicit knowledge of God. It is less feasible psychologically but has a good theological fit with Paul’s and Calvin’s versions of the thesis. This model also helps the argument for the culpability of non-belief. The second model views suppression as a process of subconscious motivated reasoning driven by a desire to avoid an uncomfortable truth. It fits Pascal’s view that one’s desire for or against God determines whether one sees general revelation as providing sufficient evidence for God. There is some empirical and anecdotal evidence for both models, but obvious cases of non-resistant non-belief present a major problem for the suppression thesis. Also, it is hard to see what might motivate anyone to deceive oneself about God’s existence. (shrink)

Five aspects of visual change detection are reviewed. The first concerns the concept of change itself, in particular the ways it differs from the related notions of motion and difference. The second involves the various methodological approaches that have been developed to study change detection; it is shown that under a variety of conditions observers are often unable to see large changes directly in their field of view. Next, it is argued that this “change blindness” indicates that focused (...) attention is needed to detect change, and that this can help map out the nature of visual attention. The fourth aspect concerns how these results affect our understanding of visual perception—for example, the implication that a sparse, dynamic representation underlies much of our visual experience. Finally, a brief discussion is presented concerning the limits to our current understanding of change detection. (shrink)

Cases in which people are self-deceived seem to require that the person hold two contradictory beliefs, something which appears to be impossible or implausible. A phenomenon seen in some brain-damaged patients known as confabulation (roughly, an ongoing tendency to make false utterances without intent to deceive) can shed light on the problem of self-deception. The conflict is not actually between two beliefs, but between two representations, a 'conceptual' one and an 'analog' one. In addition, confabulation yields valuable clues about (...) the structure of normal human knowledge-gathering processes.

I argue here that self-deception is not conducive to happiness. There is a long train of thought in social psychology that seems to say that it is, but proper understanding of the data does not yield this conclusion. Illusion must be distinguished from mere imagining. Self-deception must be distinguished from self-inflation bias and from self-fulfilling belief. Once these distinctions are in place, the case for self-deception falls apart. Furthermore, by yielding false beliefs, self-deception undermines desire satisfaction. (...) Finally, I argue for the positive view that *honest imagining* can yield the psychological benefits that others have claimed for self-deception. (shrink)

The argument in this essay will be divided into two parts: utilitarian and virtue ethics, where each party will agree or disagree with the idea that self-deception leads to happiness, taking climate change and meat production as examples to support their claims.

This paper raises a slightly uncomfortable question: are some delusional subjects responsible for their delusions? This question is uncomfortable because we typically think that the answer is pretty clearly just ‘no’. However, we also accept that self-deception is paradigmatically intentional behavior for which the self-deceiver is prima facie blameworthy. Thus, if there is overlap between self-deception and delusion, this will put pressure on our initial answer. This paper argues that there is indeed such overlap by offering a novel (...) philosophical account of self-deception. The account offered is independently plausible and avoids the main problems that plague other views. It also yields the result that some delusional subjects are self-deceived. The conclusion is not, however, that those subjects are blameworthy. Rather, a distinction is made between blameworthiness and ‘attributability’. States or actions can be significantly attributable to a subject—in the sense that they are expressions of their wills—without it being the case that the subject is blameworthy, if the subject has an appropriate excuse. Understanding delusions within this framework of responsibility and excuses not only illuminates the ways in which the processes of delusional belief formation and maintenance are continuous with ‘ordinary’ processes of belief formation and maintenance, it also provides a way of understanding the innocence of the delusional subject that does not involve the denial of agency.

It is crucial to actively detect the risks of transactions in a financial company to improve customer experience and minimize financial loss. In this study, we compare different machine learning algorithms to effectively and efficiently predict the legitimacy of financial transactions. The algorithms used in this study were: MLP Repressor, Random Forest Classifier, Complement NB, MLP Classifier, Gaussian NB, Bernoulli NB, LGBM Classifier, Ada Boost Classifier, K Neighbors Classifier, Logistic Regression, Bagging Classifier, Decision Tree Classifier and Deep Learning. The dataset (...) was collected from Kaggle depository. It consists of 6362620 rows and 10 columns. The best classifier with unbalanced dataset was the Random Forest Classifier. The Accuracy 99.97%, precession 99.96%, Recall 99.97% and the F1-score 99.96%. However, the best classifier with balanced dataset was the Bagging Classifier. The Accuracy 99.96%, precession 99.95%, Recall 99.98% and the F1-score 99.96%. (shrink)

This article explains and defends a novel idea about how people can be misled by a discussion topic, even if the discussion itself does not explicitly involve the making of false claims. The crucial aspect of this idea is that people are liable to infer, from the fact that a particular topic is being discussed, that this topic is important. As a result, they may then be led to accept certain beliefs about the state of the world they consider necessary (...) for the topic’s importance. What the article calls “importance misrepresentation” occurs when these beliefs about the state of the world are false or otherwise mistaken. The article explores different ways in which importance misrepresentation can occur, and it uses this idea to help clarify and strengthen some well‐known criticisms of the topic choices of academic philosophers.

Willful ignorance is an important concept in criminal law and jurisprudence, though it has not received much discussion in philosophy. When it is mentioned, however, it is regularly assumed to be a kind of self-deception. In this article I will argue that self-deception and willful ignorance are distinct psychological kinds. First, some examples of willful ignorance are presented and discussed, and an analysis of the phenomenon is developed. Then it is shown that current theories of self-deception give (...) no support to the idea that willful ignorance is a kind of self-deception. Afterwards an independent argument is adduced for excluding willful ignorance from this category. The crucial differences between the two phenomena are explored, as are the reasons why they are so easily conflated. (shrink)

I raise the question of what cognitive attitude self-deception brings about. That is: what is the product of self-deception? Robert Audi and Georges Rey have argued that self-deception does not bring about belief in the usual sense, but rather “avowal” or “avowed belief.” That means a tendency to affirm verbally (both privately and publicly) that lacks normal belief-like connections to non-verbal actions. I contest their view by discussing cases in which the product of self-deception is implicated (...) in action in a way that exemplifies the motivational role of belief. Furthermore, by applying independent criteria of what it is for a mental state to be a belief, I defend the more intuitive view that being self-deceived that p entails believing that p. Beliefs (i) are the default for action relative to other cognitive attitudes (such as imagining and hypothesis) and (ii) have cognitive governance over the other cognitive attitudes. I explicate these two relations and argue that they obtain for the product of self-deception. (shrink)

Three puzzles about self-deception make this mental phenomenon an intriguing explanatory target. The first relates to how to define it without paradox; the second is about how to make sense of self-deception in light of the interpretive view of the mental that has become widespread in philosophy; and the third concerns why it exists at all. In this paper I address the first and third puzzles. First, I define self-deception. Second, I criticize Robert Trivers' attempt to use (...) adaptionist evolutionary psychology to solve the third puzzle (existence). Third, I sketch a theory to replace that of Trivers. Self-deception is not an adaptation, but a spandrel in the sense that Gould and Lewontin give the term: a byproduct of other features of human (cognitive) architecture. Self-deception is so undeniable a fact of human life that if anyone tried to deny its existence, the proper response would be to accuse this person of it. (Allen Wood, 1988). (shrink)
