G protein‐coupled receptors (GPCRs) are the largest family of transmembrane receptors and primarily signal through two main effector proteins: G proteins and β‐arrestins. Many agonists of GPCRs promote “biased” responses, in which different cellular signaling pathways are activated with varying efficacies. The mechanisms underlying biased signaling have not been fully elucidated, with many potential “hidden variables” that regulate this behavior. One contributor is “location bias,” which refers to the generation of unique signaling cascades from a given GPCR depending upon (...) the cellular location at which the receptor is signaling. Here, we review evidence that GPCRs are expressed at and traffic to various subcellular locations and discuss how location bias can impact the pharmacologic properties and characterization of GPCR agonists. We also evaluate how differences in subcellular environments can modulate GPCR signaling, highlight the physiological significance of subcellular GPCR signaling, and discuss the therapeutic potential of exploiting GPCR location bias.

In this paper, we show how game theoretic work on conversation combined with a theory of discourse structure provides a framework for studying interpretive bias and how bias affects the production and interpretation of linguistic content. We model the influence of author bias on the discourse content and structure of the author’s linguistic production and interpreter bias on the interpretation of ambiguous or underspecified elements of that content and structure. Interpretive bias is an essential feature (...) of learning and understanding but also something that can be exploited to pervert or subvert the truth. We develop three types of games to understand and to analyze a range of interpretive biases, the factors that contribute to them, and their strategic effects. (shrink)

Drawing on the perspective of causal reasoning and the social cognitive theory of moral thought and action, this study explores the mechanisms underlying the association between exposure to exploitative leadership and employee workplace deviance. The results of a time-lagged survey conducted in China reveal that exposure to exploitative leadership can evoke a moral justification process that leads to increased employee organizational and interpersonal deviance. A tendency toward hostile attribution bias reinforces the direct link between exploitative leadership and moral justification (...) and the indirect effects of exploitative leadership on employee organizational and interpersonal deviance, via moral justification. The theoretical and practical implications of this study are discussed and potential directions for future studies are proposed. (shrink)

There is a long history of women being underrepresented in biomedical and health research. Specific women’s health needs have been, and in some cases still are, comparatively neglected areas of study. Concerns about the health and social impacts of such bias and exclusion have resulted in inclusion policies from governments, research funders, and the scientific establishment since the 1990s. Contemporary understandings of foregrounding sex and gender issues within biomedical research range from women’s rights to inclusion, to links between human (...) rights, women’s health and sustainable development, and the increasing scientific and funding expectation for studies to consider the sex and gender implications of research design, results and impact. However, there are also exploitation issues to consider when foregrounding the inclusion of women as research participants, especially for research ethics committees and institutional review boards. A hidden risk is that exploitative research designs and practices may be missed, particularly by reviewers who may not have a nuanced understanding of gender-based harm. Utilizing contemporary case studies of ethics dumping, this paper highlights some of the concerns, and makes recommendations for IRBs/research ethics reviewers to help ensure that essential research is undertaken to the highest ethical standards.

I discuss under what conditions the objection that an expert’s argument is biased by her self-interest can be a meaningful and sound argumentative move. I suggest replacing the idea of bias qua self-interest by that of a conflict of interests, exploit the distinction between an expert context and a public context, and hold that the objection can be meaningful. Yet, the evaluation is overall negative, because the motivational role of self-interest for human behavior remains unclear. Moreover, if recent social-psychological (...) results from the “heuristics and biases” program are accepted, it is plausible to assume that humans also satisfice (rather than optimize/maximize) when identifying and then acting in their self-interest. My thesis is: insofar as the objection is sound with a particular audience, it is not needed; and insofar as the objection is needed, it is unsound. (shrink)

This paper focuses on the potential of “equitech”—AI technology that improves equity. Recently, interventions have been developed to reduce the harm of implicit bias, the automatic form of stereotype or prejudice that contributes to injustice. However, these interventions—some of which are assisted by AI-related technology—have significant limitations, including unintended negative consequences and general inefficacy. To overcome these limitations, we propose a two-dimensional framework to assess current AI-assisted interventions and explore promising new ones. We begin by using the case of (...) human resource recruitment as a focal point to show that existing approaches have exploited only a subset of the available solution space. We then demonstrate how our framework facilitates the discovery of new approaches. The first dimension of this framework helps us systematically consider the analytic information, intervention implementation, and modes of human-machine interaction made available by advancements in AI-related technology. The second dimension enables the identification and incorporation of insights from recent research on implicit bias intervention. We argue that a design strategy that combines complementary interventions can further enhance the effectiveness of interventions by targeting the various interacting cognitive systems that underlie implicit bias. We end with a discussion of how our cognitive interventions framework can have positive downstream effects for structural problems. (shrink)

Policymakers and institutions have developed an increasing interest in applying principles from cognitive science to encourage individuals to adopt behaviors, attitudes and perspectives that enable them to reach higher levels of personal and collective well-being. We focused on the value of nudging people to adopt a broader farsighted view when making their day-to-day decisions, overcoming the temporal discounting bias which leads them to prefer smaller immediate gains to larger future rewards. Following recent advances in the literature, we tried to (...) mitigate this myopia promoting the connection that individuals feel between their present and future selves through a nudge which capitalizes on their natural tendency to illusory superiority. We defined and tested a paradigm to exploit persuasively this optimistic bias to mitigate temporal discounting through the mediation of an increased future self-continuity. Implications for well-being and public policies are discussed. (shrink)

Radical skepticism is the view that we know nothing, or at least next to nothing. Nearly no one actually believes that skepticism is true. Yet it has remained a serious topic of discussion for millennia and it looms large in popular culture. What explains its persistent and widespread appeal? How does the skeptic get us to doubt what we ordinarily take ourselves to know? I present evidence from two experiments that classic skeptical arguments gain potency from an interaction between two (...) factors. First, people evaluate inferential belief more harshly than perceptual belief. Second, people evaluate inferential belief more harshly when its content is negative (i.e. that something is not the case) than when it’s positive (i.e. that something is the case). It just so happens that potent skeptical arguments tend to focus our attention on negative inferential beliefs, and we are especially prone to doubt that such beliefs count as knowledge. That is, our cognitive evaluations are biased against this specific combination of source and content. The skeptic sows seeds of doubt by exploiting this feature of our psychology. (shrink)

Despite the closure of virtually all original grindhouse cinemas, ‘grindhouse’ lives on as a conceptual term. This article contends that the prevailing conceptualization of ‘grindhouse’ is problematized by a widening gap between the original grindhouse context (‘past’) and the DVD/home-viewing context (present). Despite fans’ and filmmakers’ desire to preserve this part of exploitation cinema history, the world of the grindhouse is now little more than a blurry set of tall-tales and faded phenomenal experiences, which are subject to present-bias. (...) The continuing usefulness of grindhouse-qua-concept requires that one should pay heed to the contemporary contexts in which ‘grindhouse’ is evoked. (shrink)

This paper articulates a radical feminist analysis of psychotherapist-patient sexual exploitation, a problem that has affected an estimated one million North American women. I argue that such exploitation is rooted in misogynous attitudes that pervade the major institutions in contemporary culture, including the mental health professions. I examine ways that mental health professionals use sexist constructs and language to blame victims for their abuse. Through textual analysis of a series of letters and articles by prominent psychiatrists, I show (...) that the male writers attempted to silence victims and their female advocates by subjugating the women's voices to their rhetorical control and by indirectly drawing on the power of deeply-held cultural stereotypes of women. This analysis of therapist-patient sexual exploitation and the blaming of its victims points to the broader problem of oppressive androcentric bias in psychiatry's ideology, epistemology, and discourse. The article closes with a suggestion for correcting psychiatry's harmful biases and with recommended strategies for preventing psychotherapist-patient sexual exploitation. (shrink)

Some evolutionary psychologists claim that humans are good at creating superstimuli, and that many pleasure technologies are detrimental to our reproductive fitness. Most of the evolutionary psychological literature makes use of some version of Lorenz and Tinbergen’s largely embryonic conceptual framework to make sense of supernormal stimulation and bias exploitation in humans. However, the early ethological concept “superstimulus” was intimately connected to other erstwhile core ethological notions, such as the innate releasing mechanism, sign stimuli and the fixed action (...) pattern, notions that nowadays have, for the most part, been discarded by ethologists. The purpose of this paper is twofold. First, we will reconnect the discussion of superstimuli in humans with more recent theoretical ethological literature on stimulus selection and supernormal stimulation. This will allow for a reconceptualisation of evolutionary psychology’s formulation of (supernormal) stimulus selection in terms of domain-specificity and modularity. Second, we will argue that bias exploitation in a cultural species differs substantially from bias exploitation in non-cultural animals. We will explore several of those differences, and explicate why they put important constraints on the use of the superstimulus concept in the evolutionary social sciences. (shrink)

Philosophers of science have argued that epistemic diversity is an asset for the production of scientific knowledge, guarding against the effects of biases, among other advantages. The growing privatization of scientific research, on the contrary, has raised important concerns for philosophers of science, especially with respect to the growing sources of biases in research that it seems to promote. Recently, Holman and Bruner ( 2017 ) have shown, using a modified version of Zollman ( 2010 ) social network model, that (...) an industrial selection bias can emerge in a scientific community, without corrupting any individual scientist, if the community is epistemically diverse. In this paper, we examine the strength of industrial selection using a reinforcement learning model, which simulates the process of industrial decision-making when allocating funding to scientific projects. Contrary to Holman and Bruner’s model, in which the probability of success of the agents when performing an action is given a priori, in our model the industry learns about the success rate of individual scientists and updates the probability of success on each round. The results of our simulations show that even without previous knowledge of the probability of success of an individual scientist, the industry is still able to disrupt scientific consensus. In fact, the more epistemically diverse the scientific community, the easier it is for the industry to move scientific consensus to the opposite conclusion. Interestingly, our model also shows that having a random funding agent seems to effectively counteract industrial selection bias. Accordingly, we consider the random allocation of funding for research projects as a strategy to counteract industrial selection bias, avoiding commercial exploitation of epistemically diverse communities.

A complex conjuncture of ideological constructions obscured and rationalized the systematic exploitation of farm women. First, farming and homemaking, to which people cling in an attempt to avert the alienation of wage labor, provide a basis for evaluating one's labor in terms that, ironically, makes them vulnerable to super-exploitation. Second, agrarian ideologies, with their strongly patriarchal bias, did not allow women to understand themselves as public actors. Modernizing elite ideologies, specifically the equation of entrepreneurial individualism and efficiency (...) with “progress” and affluence, and the “cult of domesticity” with its redefinition of men's and women's roles, promised women greater equality within the family; however, these normative codes simultaneously opened the farm and home to greater dependence on capitalist markets. The ideology of entrepreneurial individualism also provided templates through which farm men and women (mis)understood their relative poverty as being the result of private, individual choices. In addition, virtually all media assumed a sector differentiated only by commodity, rendering size, class, or other distinctions invisible. Finally, the ideology of separate spheres, as it developed in the nineteenth century, created a segmented and discriminatory labor market for women. The period focused on, the late 1940s and the 1950s, was crucial in establishing the terms of the post-War order. (shrink)

Aesthetics and social cognition are two disciplines rarely merged, despite the penetration of artworks into social, moral, and political concerns. In particular, participatory artworks involve direct social interaction and perception, and are more often than not motivated by, and aim towards, ethico-political ends. In the following, I fuse considerations aesthetic with considerations intersubjective, arguing that participatory artworks engage and exploit empathy’s biased character towards a recalibration of our social relationships, namely inclusion and exclusion. Although critics of empathy suggest that its (...) biased, manipulable, and narrow characteristics are detrimental to its moral promise, I argue that participatory artworks are successful intervention methods just insofar as they use these characteristics for their ethico-political gain. This is stimulated by their facilitation of affective, primary intersubjectivity, something I argue is unique to participatory art. After detailing these operations, I suggest that works that seek to address exclusion, rather than those that facilitate inclusion, have a greater potency in addressing and recalibrating empathy, in part owing to their provocation of empathy-related emotions and forms of fellow-feeling such as shame and compassion.

Barely seventeen years into the twenty-first century, our world continues to be plagued by endless wars and violence. Africa is not immune from these crises. As many countries in Africa celebrate more than fifty years of independence from colonial rule, Africa is still the poorest continent in the world. Religious wars, genocides, ethnic and tribal cleansings have come to define the continent’s contemporary history. Corruption, nepotism, dictatorship, disregard for human life, tribalism, and many social vices are normalized realities in many (...) parts of the continent. Rather than despair, a radical refocusing on Africa’s rich history of hospitality that affirms the flourishing of all life ought to be embraced. This article aims to do exactly this by exploring Africa’s role and place in the history of three Abrahamic religions; Judaism, Christianity, and Islam. While celebrating Africa’s unique role as the gateway for the realization of divine hospitality, this article aims to serve as a witness to an ethic of life that is relevant for the global church’s vision and mission to a pluralistic world and for the mission of the churches of Africa to addressing the social, cultural, and political crises faced by the continent. To achieve these, this work appropriates a comparative theological method that sheds light on the centrality of Africa in these three Abrahamic religions with a bias for the flourishing of life. Keywords: Africa, Hospitality, Life, Christianity, Islam, Judaism. (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. -/- .

Through numbers of studies on the formation of equivalence relations and causal induction, it is known that human beings tend to consider conditional statements ``if p then q " as biconditional statements ``if and only if p then q ": we call the tendency to perceive ``if p then q " as ``if q then p " the ``symmetry bias". On the other hand, many studies on children's word learning have pointed out that children tend to expect each object (...) has only one label. This is so-called the ``mutual exclusivity bias". This bias implies. (shrink)

We raise the new possibility that people diagnosed with developmental dyslexia (DD) are specialized in explorative cognitive search, and rather than having a neurocognitive disorder, play an essential role in human adaptation. Most DD research has studied educational difficulties, with theories framing differences in neurocognitive processes as deficits. However, people with DD are also often proposed to have certain strengths – particularly in realms like discovery, invention, and creativity – that deficit-centered theories cannot explain. We investigate whether these strengths reflect (...) an underlying explorative specialization. We re-examine experimental studies in psychology and neuroscience using the framework ofcognitive search, whereby many psychological processes involve a trade-off between exploration and exploitation. We report evidence of an explorative bias in DD-associated cognitive strategies. High DD prevalence and an attendant explorative bias across multiple areas of cognition suggest the existence of explorative specialization. An evolutionary perspective explains the combination of findings and challenges the view that individuals with DD have a disorder. In cooperating groups, individual specialization is favored when features that confer fitness benefits are functionally incompatible. Evidence for search specialization suggests that, as with some other social organisms, humans mediate the exploration–exploitation trade-off by specializing in complementary strategies. The existence of a system of collective cognitive search that emerges through collaboration would help to explain our species’ exceptional adaptiveness. It also aligns with evidence for substantial variability during our evolutionary history and the notion that humans are adapted not to a particular habitat but to variability itself. Specialization creates interdependence and necessitates balancing complementary strategies. Reframing DD therefore underscores the urgency of changing certain cultural practices to ensure we do not inhibit adaptation. Key improvements would remove cultural barriers to exploration and nurture explorative learning in education, academia, and the workplace, as well as emphasize collaboration over competition. Specialization in complementary search abilities represents a meta-adaptation; through collaboration, this likely enables human groups (as a species and as cultural systems) to successfully adapt. Cultural change to support this system of collaborative search may therefore be essential in confronting the challenges humanity now faces. (shrink)

To explore how model building adapts to changing environments, we had participants play “rock-paper-scissors” against a computer that played a frequency bias or a player-dependent bias and then switched. Participants demonstrated their use of prior experience in how quickly they recognized and exploited changes in the computer's play strategy; in general, the more similar the strategies, the more efficient the updating. These findings inform our understanding of previously reported updating impairments in right-brain damaged patients.

In this volume, Rachel Giora explores how the salient meanings of words - the meanings that stand out as most prominent and accessible in our minds - shape how we think and how we speak. For Giora, salient meanings display interesting effects in both figurative and literal language. In both domains, speakers and writers creatively exploit the possibilities inherent in the fact that, while words have multiple meanings, some meanings are more accessible than others. Of the various meanings weencode in (...) our mental lexicon for a given word or expression, we ascribe greater cognitive priority to some over others. Interestingly, the most salient meaning is not always the literal meaning. Giora argues that it is cognitively prominent salient meanings, rather than literal meanings, that play the most important role in the comprehension and production of language. She shows that even though context begins to affect comprehension immediately, it does so without obstructing the early accessing of salient meanings. Thus, the meaning we first attend to is the salient word meaning, regardless of contextual bias. Knowledge of salient meanings turns out to play a major role, perhaps the most important role, in the process of using and understanding of language. Going beyond the familiar effects of literal meaning and context, the Graded Salience Hypothesis presents the most comprehensive explanation for how we use language for meaning. In this volume, Giora presents her new model for the first time in a book-length treatment, with original and illuminating perspectives that will be of interest to linguists, philosophers, psychologists, and all who want to know more about just how we understand what we mean.

The poverty of stimulus argument is one of the most controversial arguments in the study of language acquisition. Here we follow previous approaches challenging the assumption of impoverished primary linguistic data, focusing on the specific problem of auxiliary (AUX) fronting in complex polar interrogatives. We develop a series of corpus analyses of child-directed speech showing that there is indirect statistical information useful for correct auxiliary fronting in polar interrogatives and that such information is sufficient for distinguishing between grammatical and ungrammatical (...) generalizations, even in the absence of direct evidence. We further show that there are simple learning devices, such as neural networks, capable of exploiting such statistical cues, producing a bias toward correct AUX questions when compared to their ungrammatical counterparts. The results suggest that the basic assumptions of the poverty of stimulus argument may need to be reappraised. (shrink)

Current views of the control of complex, purposeful movements acknowledge that organizational processes must reconcile multiple concerns. The central priority is of course accomplishing the actor's goal. But in specifying the manner in which this occurs, the action plan must accommodate such factors as the interaction of mechanical forces associated with the motion of a multilinked system (classical mechanics) and, in many cases, intrinsic bias toward preferred movement patterns, characterized by so‐called “coordination dynamics.” The most familiar example of the (...) latter is the symmetry constraint, where spatial trajectories and/or temporal landmarks (e.g., reversal points) of concurrentlymoving body segments (limbs, digits, etc.) exhibit mutual attraction. The natural coordination tendencies that emerge through these constraints can facilitate or hinder motor control, depending on the degree of congruency with the desired movement pattern. Motor control theorists have long recognized the role of classical mechanics in theories of movement organization, but an appreciation of the importance of intrinsic interlimb bias has been gained only recently.Although detailed descriptions of temporal coordination dynamics have been provided, systematic attempts to identify additional salient dimensions of interlimb constraint have been lacking. We develop and implement here a novel method for examining this problem by exploiting two robust principles of psychomotor behavior, the symmetry constraint and the Two‐Thirds Power Law. Empirical evidence is provided that the relative spatial patterns of concurrently moving limbs are naturally constrained in much the same manner as previously identified temporal constraints and, further, that apparent velocity interference is an indirect, secondary consequence of primary spatial assimilation. The theoretical implications of spatial interference are elaborated with respect to movement organization and motor learning. The need to carefully consider the appropriate dimensions with which to characterize coordination dynamics is also discussed. (shrink)

Recent research into cultural transmission suggests that humans are disposed to learn, remember, and transmit certain types of information more easily than others, and that any information that is passed between people will be subjected to cognitive selective pressures that alter the content and structure so as to make it maximally transmittable. This paper presents a review of emerging research on content biases in cultural evolution with relevance to the transmission of popular narratives. This is illustrated with content analysis of (...) urban legends, which found that most exploited at least one known content bias, with emotional information and social information being the most frequent. We argue that the narratives do not succeed because of the transmission of adaptively relevant information but because of their exploitation of content biases in human cognition. (shrink)

There are many circumstances in which vegans are treated or considered worse than nonvegans, both in the private and the public sphere, either due to the presence of a bias against them or for structural reasons. For instance, vegans sometimes suffer harassment, have issues at their workplace, or find little vegan food available. In many cases they are forced to contribute to, or to participate in, animal exploitation against their will when states render it illegitimate to oppose or (...) refuse to support some uses of animals. For the most part this remains socially invisible. Vegans, however, often recognize this as a form of discrimination against them. But they seldom campaign against it, as they regard it as a consequence of another and more important discrimination, i.e. speciesist discrimination against nonhuman animals. If this is correct, discrimination against vegans can be characterized as a form of second-order discrimination, that is, discrimination against those who oppose another form of discrimination. If speciesism really is unjustified and discriminatory, then discrimination against vegans will always be discriminatory and unjustified too. But even if our current attitudes towards animals were justified there would be strong reasons to claim that vegans do suffer several forms of private and public discrimination that are unjustified.

Human communication is multi-modal. It is an empirical fact that many of our acts of communication exploit a variety of means to make our communicative intentions recognisable. Scholars readily distinguish between verbal and non-verbal means of communication, and very often they deal with them separately. So it is that a great number of semanticists and pragmaticists give verbal communication preferential treatment. The non-verbal aspects of an act of communication are treated as if they were not underlain by communicative intentions. They (...) are “relegated” to mere aspects of the context. However, several schools of thoughts have a different take on the issue. Thus psychologists or semioticians of gesture have shown how intricately gestures and speech are related in utterances. And, in a different area of the theoretical landscape, so-called “Relevance Theorists” have made the same point. Thus, Robyn Carston writes that “the domain of pragmatics is a natural class of environmental phenomena, that of ostensive stimuli; verbal utterances are the central case, but not the only one, and they themselves are frequently accompanied by other ostensive gestures of the face, hands, voice etc, all of which have to be interpreted together if one is to correctly infer what is being communicated”. This position rests on the assumption that there is a single “pragmatic system” or module at work in the interpretation of “ostensive stimuli”. When it comes to interpreting verbal stimuli, the same mechanisms and resources are used as when it comes to processing non-verbal ones. If there is no distinct “linguistic pragmatic system”, then the scholar who studies communication should not favour the verbal at the expense of the non-verbal. In this paper, I want to make a contribution to the study of multi-modal messages by considering a type of utterances that mix the verbal with the non-verbal in such a way that a piece of non-linguistic communication seems to stand in for a linguistic constituent which remains unrealised. Here is a real-life example : I didn't see the [IMITATION OF FRIGHTENING GRUMPINESS] woman today; will she be back this week? The square-bracketed string in small capitals is meant to capture the facial expressions and gestures performed in the conversational setting. What is intriguing here is that this instance of ostensive mimicry does not come as a mere complement to some linguistic stimulus; it appears to take the place of that stimulus. I shall try to show that a linguistic analysis can indeed be offered for cases like – though, I believe, without succumbing to the pro-linguistic bias that Carston warns against. I will, however, argue against an ellipsis-based account : the structure of sentence does not contain an unrealised adjective phrase. Instead, I shall defend a ‘syntactic-recruitment' account.

This paper examines the impact and implications of ChatGPT and other generative AI technologies within the African context while looking at the ethical benefits and concerns that are particularly pertinent to the continent. Through a robust analysis of ChatGPT and other generative AI systems using established approaches for analysing the ethics of emerging technologies, this paper provides unique ethical benefits and concerns for these systems in the African context. This analysis combined approaches such as anticipatory technology ethics (ATE), ethical impact (...) assessment (EIA), and ethical issues of emerging ICT applications with AI (ETICA) with specific issues from the literature. The findings show that ChatGPT and other generative AI systems raise unique ethical concerns such as bias, intergenerational justice, exploitation of labour and cultural diversity in Africa but also have significant ethical benefits. These ethical concerns and benefits are considered crucial in shaping the design and deployment of ChatGPT and similar technologies responsibly. It further explores the potential applications of ChatGPT in critical domain areas such as education, agriculture, and healthcare, thereby demonstrating the transformative possibilities that these technologies can have on Africa. This paper underscores the critical role of AI governance as Africa increasingly adopts ChatGPT and similar AI systems. It argues that a comprehensive understanding of AI governance is essential not only for maximising the benefits of generative AI systems but also for facilitating a global dialogue. This dialogue aims to foster shared knowledge and insights between the Global North and the Global South, which is important for the development and creation of inclusive and equitable AI policies and practices that can be beneficial for all regions.

Corporate Social Responsibility is a label covering managerial checks and institutional balances introduced against the background of ethical values. Values are clearly formulated and organizational processes are designed with the inclusion of stakeholders and their voice in mind. In case of the post-communist societies designers of CRS cope with an additional level of complexity. Original sin of market reforms after the political fall of the communist regimes is the corrupt take-over of markets and democracies. Social institutions of capitalist markets and (...) democratic states have been subverted and invaded by the unpurged networks of the post-communist power elites. They privatized the wealth of state enterprises becoming new owners of economic resources and they drifted towards the top functions in state institutions becoming post-communist power brokers. Their long-term monopoly of the media left them in command of the mainstream PR communications long after their absolute political power was gone. Democratic institutions, and the right to free speech are daily challenged by influential image and market competition. They cannot be taken for granted. Some democratic institutions are undermined by subversive networks of the corrupt mafias often formed by ex-functionaries of the communist party and her secret services. Their tacit power is explicitly legitimized by media-clusters of cultural representatives of the communist ex-power elites exploiting leftist bias of media mainstreams. (shrink)

This configuration either remained stable, changed its shaft length or the orientation of the tails during movement execution.

The illusion bias emerged for perturbations shortly after movement onset and for perturbations during execution, the latter of which allowed only a minimum of time for making adjustments (...) .

This dissertation defends the place of representation in music. Music’s status as a representational art has been hotly debated since the War of the Romantics, which pitted the Weimar progressives (Liszt, Wagner, &co.) against the Leipzig conservatives (the Schumanns, Brahms, &co.) in an intellectual struggle for what each side took to be the very future of music as an art. I side with the progressives, and argue that music can be and often is a representational medium. Correspondence (or resemblance) theories (...) of representation, such as the one I offer, have been much maligned in philosophy since the 1960s. Most theories assimilate representation under “meaning,” which has usually been thought to belong primarily to language. As a result, representational content has been taken to be purely conventional in the way that sentential meaning is. People want to know what music “means,” and these theories interpret this as “what does it refer to?” or “what propositions does it express?” I argue that propositional communication is only one (small) part of the issue. Once we overcome the bias of conceiving of musical works as essentially linguistic items, speech acts (performed) or sentence tokens (written), we can begin to take music on its own terms to discover how it represents—one way in which it “means.” The first step is to “naturalize” music’s representational content. Influenced by recent discussions in the philosophies of mind and science, I argue in Chapter 1 that composers represent extra-musical objects, events, and states of affairs through their works by exploiting antecedent relations (such as similarities in pitch, timbre, and structure) in order to secure reference to them. In Chapter 2, I survey and respond to the main challenges that those skeptical of music’s representational possibilities would raise against my theory of musical representation. In Chapter 3, I explore a number of ways through which music has been claimed to represent in order to show how my theory accounts for these diverse phenomena better than its conventionalist rivals, both in terms of the metaphysics and the epistemology. Chapter 4 extends this discussion by offering an account of how we perceive, understand, appreciate, and interpret sophisticated musical representations. I conclude by teasing out some of my theory’s implications and suggesting areas for further research. (shrink)

Three interrelated communicative issues emerge from recent U.S. political discourse in the wake of Donald Trump’s campaign for and election to the presidency. TRUTH figures prominently in social commentary on language. Semantically, truth relates to applicability conditions for linguistic expressions, which change and can be contested. Pragmatically, truth affects updating participants’ changing public commitments to what the world is like and to their own and others’ future actions. Updating as the speaker wants requires TRUST. Taking speakers as personally credible is (...) heavily tied to social identities and power relations. Experts and other “authorities” are often automatically accorded credibility but sometimes wrongly shielded from criticism. Disdain for expertise fueled Trump’s campaign and the social divides it exploited, continuing during his presidency. Although TRUMPERY (orig., “deceit, fraud”) is not confined to Trump or Trumpists, they are consummate practitioners. Communicative trumpery exploits “confirmation bias,” desires, and assumptions producing beliefs. It also arises from shifting interpretations and is key to evade communicative accountability (“just joking,” “a figure of speech”) or from refusing to engage with other discourse participants.

Using a recent example from US politics as representative of contemporary liberal democracies, this chapter highlights how public opinion is shaped through the exploitation of our epistemic interdependence and partisan bias. Climate change was an important issue leading into the 2010 US mid-term elections. Public opinion on climate change was subject to a number of willfully disseminated distorting influences, having a significant impact on the election’s outcome and subsequent political discourse surrounding climate change policies. One impact of this (...) type of exploitation is that it has epistemically compromising effects on the electorate, which in turn undermines democratic legitimacy. In the interest of defending democratic legitimacy, this chapter suggests we re-evaluate and update those liberal institutions necessary for informed public opinion surrounding our current political epistemic needs.

In recent years, the research field of the evolution of art has witnessed contributions from a wide range of disciplines across the "three cultures". In this thesis, I make both a critical review of existing explanations, and try to do elucidate the evolution of art by employing insights, methods and concepts from different disciplines. First, I critically evaluate the evidentiary criteria from standard evolutionary psychology some accounts employ to demonstrate that art qualifies as a human biological adaptation. I argue that (...) these criteria do not suffice to make that claim. Furthermore, I make the case for a cultural evolutionary approach to the arts. One commonly used evidentiary criterion for art as adaptation is the “tight fit” between artnbsp;human cognition, which is interpreted as suggesting that cognition has undergone selection to produce and appreciate art. However, disentangling cultural and genetic evolution allows formulating thenbsp;hypothesis that art has evolved culturally to match human cognition. Second, I observe that in ancient and modern hunter gatherer societies, artistic activities are virtually alwaysnbsp;with ritual. I discuss what this implies for the adaptive significance of art. Specifically, if the arts have culturally evolved in function of ritualistic purposes, their adaptive value has depended on the adaptiveness of ritual. Third, because architecture is characterized by the combination of utilitarian and aesthetic aspects, it is particularly interesting from an evolutionary perspective and therefore I devote special attention to it. Employing the cross-species comparative approach, I investigate two main purposes human architecture has in common with nonhuman animal constructions: protection andnbsp;Based on the phylogenetic approach I establish that protection may have been the primary function of building aptitudes in humannbsp;and that building was later co-opted for signaling purposes. Subsequently, I comparatively evaluate thenbsp;of signaling models in the cultural evolution of architectural aesthetics. Furthermore I combine insights from environmental psychology, niche construction and cultural evolution theory to develop the hypothesis that a function of religious monumental architecture may have been to support nbsp;or even to galvanize nbsp;social learning. Finally, I connect the account I developed to the cognitive science of religion. I complement the frequently held view that religious monumental architecture is a costly signal with the mechanism of sensory exploitation. I attempt to demonstrate that by exploiting thenbsp;response of awe in religious followers, religious monumental architecture promotes and regulates prosocial behavior and creates in them an openness to adopt supernatural beliefs. Fourth, I dealnbsp;the evolution of visual art, paying again special attention to cultural evolution andnbsp;explanatory value of sensory exploitation. I assert that the relatively late appearance of figurative art in the course of human evolution may be attributed to an increase in the number of social learning opportunities within and between human populations at that time. I support this assertion with archaeological data that indicate overall population growth and increased population densities at that time. These demographic changes, I argue, have allowed the retention and accumulation of innovations required for figurative art making. Contrary to previous accounts, I furthermore aim to show that this process doesnbsp;require figurative art to have served adaptive purposes. Employing sensory exploitation, I establish that figurative art could have evolved by exploiting pre-existing biases of evolved psychology. The dominant themes of upper Paleolithic and late stone age figurative art, animals and humans, seem to support this contention. Fifth, I present a number of experimental studies I conducted to verify whether contemporary art experts would have socially learned to resist exploitation of evolved psychology. One aspect ofrsquo;s exploitative power may be that it elicits aesthetic pleasure by pushing “pleasure buttons” that evolved for other purposes. Consequently, spectators may trade-off rewards from indulging in art and biological activities, resulting in less effort being allocated to reproduction. I contend that, while the generalnbsp; may indeed be exploited, experts, who are typically being exposed to high doses of art, may have socially learned to resist exploitation by selectively preferring art from prestigious art contexts. The latter would be in line with the claim that prestige bias may trump content biases of evolved psychology. The results of three experimental studies supportnbsp;contention. I find that laypeople's art appreciation is positively affected by a content bias for attractive faces, mediated by aesthetic pleasure, whereas experts' appreciation is positively affected by prestige and mediated by admiration for the artist. Moreover, experts confer lower appreciation to attractive compared to moderately attractive content, which is consistentnbsp;the contention that expertise and the use of prestige are associatednbsp;resistance against beautiful content that exploits evolved preferences. This research thus suggests that expertise moderates content and context biases, which may be of relevance to an ongoing debate about their relative importance as drivers of cultural evolution. In addition, this study provides a tentative but novel explanation for the fact, famously established by philosopher Arthur Danto, that beauty lost its central position in Western art during the 20th century. However my findings cannot exclude alternative explanations for the fact that art expert appreciation deviates from evolved aesthetic preferences. Further research may experimentally assess the role of prestige bias and resistance as drivers of this deviation versus other, previously suggested, potential processes. For example, preferences of experts may deviate on account of the fact that art serves as a badge of elite group membership and thus expert art appreciation as a means to distinguish oneself from the masses. Alternatively, art experts may seek intellectual challenges instead of pushing pleasure buttons. Future research may experimentally verify the respective roles of these different hypothesized mechanisms. In addition, it may be investigated how insights from sexual selection research may help elucidating the different processes at play in cultural evolution and particularly in the cultural evolution of art appreciation, given the commonalities between sexual selection and cultural selection models.

The article develops an Ignatian perspective, from within which it then interprets and amplifies Bernard Lonergan's intellectual project. Exploiting recent analyses of medieval memorial culture and the rhetorical dynamicsof monastic spiritual practice, the article highlights the performative quality of key Ignatian texts, paying particular attention to the categories of ornamentation and ordering . Appreciating the vantage afforded by heightened self-presence, reflexive knowledge and intentional praxis, the article then explores Lonergan's project, employing the rubric of ornamentation and ordering to investigate the (...) interaction between cognitional activity and the matrix of desire informed by unbounded wonder, specific desires and distorting bias. Formative self-appropriation is then considered as a religious process, in which the self gathers the resources of Scripture and tradition to compose a creative faith response to the divine initiative of transforming love, a response that unfolds more fully in the co-development of personal, social and cultural activity.

As the lowest in the caste hierarchy, Dalits in Indian society have historically suffered caste-based social exclusion from economic, civil, cultural, and political rights. Women from this community suffer from not only discrimination based on their gender but also caste identity and consequent economic deprivation. Dalit women constituted about 16.60 percent of India’s female population in 2011. Dalit women’s problems encompass not only gender and economic deprivation but also discrimination associated with religion, caste, and untouchability, which in turn results in (...) the denial of their social, economic, cultural, and political rights. They become vulnerable to sexual violence and exploitation due to their gender and caste. Dalit women also become victims of abhorrent social and religious practices such as devadasi/jogini, resulting in sexual exploitation in the name of religion. The additional discrimination faced by Dalit women on account of their gender and caste is clearly reflected in the differential achievements in human development indicators for this group. In all the indicators of human development, for example, literacy and longevity, Dalit women score worse than Dalit men and non-Dalit women. Thus, the problems of Dalit women are distinct and unique in many ways, and they suffer from the ‘triple burden’ of gender bias, caste discrimination, and economic deprivation. To gain insights into the economic and social status of Dalit women, our paper will delve more closely into their lives and encapsulate the economic and social situations of Dalit women in India. The analyses of human poverty and caste and gender discrimination are based on official data sets as well as a number of primary studies in the labor market and on reproductive health. (shrink)

Understanding how people behave when facing hazardous situations, how intrinsic and extrinsic factors influence the risk taking (RT) decision making process and to what extent it is possible to modify their reactions externally, are questions that have long interested academics and society in general. In the spheres of Occupational Safety and Health (OSH), the military, finance and sociology, this topic has multidisciplinary implications because we all constantly face risk taking situations. Researchers have hitherto assessed risk taking profiles by conducting questionnaires (...) prior to and after the presentation of stimuli; however, this can lead to the production of biased, non-realistic, risk taking profiles. This is due to the reflexive nature of choosing an answer in a questionnaire, which is remote from the reactive, emotional and impulsive decision making processes inherent to real, risky situations. One way to address this question is to exploit VR capabilities to generate immersive environments that recreate realistic seeming but simulated hazardous situations. We propose VR as the next-generation tool to study risk taking processes, taking advantage of the big four families of metrics which can provide objective assessment methods with high ecological validity: the real-world risks approach (high presence VR environments triggering real-world reactions), embodied interactions (more natural interactions eliciting natural behaviours), stealth assessment (unnoticed real-time assessments offering efficient behavioural metrics) and physiological real-time measurement (physiological signals avoiding subjective bias). Additionally, VR can provide an invaluable tool, after the assessment phase, to train in skills related to risk taking due to its transferability to real-world situations. (shrink)

The conduct of prior ethics review of human research projects helps to protect vulnerable groups or populations from potential negative impacts of research. Contemporary considerations in human research considers the concept of vulnerability in terms of access to research opportunities, impacts on the consenting process, selection bias, and the generalisability of results. Recent work questions the validity of using enumerated lists as a check box approach to protect research participants from exploitation. Through the use of broad categories to (...) treat cohorts of human research participants as homogenous classes and label some participants as vulnerable merely because they are members of a particular class, some ethics reviewers have used the National Statement on Ethical Conduct in Human Research to strip individuals of their “ethical equality”. Labelling people as vulnerable does not help researchers or human research ethics committee members develop an understanding of the complexities of applying the principles of respect and of justice in ethical decision-making. Conversely, defining specific cohorts of research participants as needing nuanced ethical consideration, due to their vulnerable nature, may imply that other population groups need not be considered vulnerable. We contend that this assumption is erroneous. This paper explores the way that human research ethics guidance documents treat vulnerability within the Australian context and draws on contemporary discussion to focus an alternative perspective based on the principles in the National Statement on Ethical Conduct in Human Research for researchers and human research ethics committee members to consider.

Multiple measures of decision-making under uncertainty (e.g. jumping to conclusions (JTC), bias against disconfirmatory evidence (BADE), win-switch behavior, random exploration) have been associated with delusional thinking in independent studies. Yet, it is unknown whether these variables explain shared or unique variance in delusional thinking, and whether these relationships are specific to paranoia or delusional ideation more broadly. Additionally, the underlying computational mechanisms require further investigation. To investigate these questions, task and self-report data were collected in 88 individuals (46 healthy (...) controls, 42 schizophrenia-spectrum) and included measures of cognitive biases and behavior on probabilistic reversal learning and explore/exploit tasks. Of those, only win-switch rate significantly differed between groups. In regression, reversal learning performance, random exploration, and poor evidence integration during BADE showed significant, independent associations with paranoia. Only self-reported JTC was associated with delusional ideation, controlling for paranoia. Computational parameters increased the proportion of variance explained in paranoia. Overall, decision-making influenced by strong volatility and variability is specifically associated with paranoia, whereas self-reported hasty decision-making is specifically associated with other themes of delusional ideation. These aspects of decision-making under uncertainty may therefore represent distinct cognitive processes that, together, have the potential to worsen delusional thinking across the psychosis spectrum.

This dissertation compares the notions of homo rationalis in Philosophy and homo oeconomicus in Economics. Particularly, in Part I, we claim that both notions are close methodological substitutes. Accordingly, we show that the constraints involved in the notion of economic rationality apply to the philosophical notion of rationality. On these premises, we explore the links between the notions of Kantian and Humean rationality in Philosophy and the constructivist and ecological approaches to rationality in economics, respectively. Particularly, we show that the (...) constraints involved in both approaches to rationality in economics apply to the notions of Kantian and Humean rationality. That is why we introduce the notion of minimal global rationality. In a nutshell, the latter links one’s rationality to one’s ability to make good use of their cognitive apparatus to process contextual variables. On this basis, in Part II, we present two empirical tests showing that minimal global rationality is at work in philosophical experiments because systematic manipulations of contextual variables predictably affect philosophical judgment in the Trolley Problem and in some Knobe-like vignettes. In the first case, the manipulation of the information provided to subjects predictably causes inconsistent judgments. More precisely, subjects’ response to information shocks predictably causes them to issue inconsistent judgments. Instead, in the second case, our experimental results reveal that the Knobe Effect activates only if the perpetrator of an action is likely to be perceived as evil and unfriendly. Besides, when the Knobe-like vignettes include probabilistic outcomes, the Knobe Effect does not activate or is reduced in magnitude. For these reasons, we maintain that the availability heuristic bias arguably affects one’s judgment in Knobe-like experiment settings. Eventually, in Part III, we survey the general implications of the findings presented in Part II. First and foremost, we show that when manned social media algorithms produce wide-ranging availability cascades, agents predictably respond to those cascades by herding around biased claims. Interestingly, we find that the exposure to similarly redundant online content makes new social groups emerge unhindered. That is why populists and conspiracy theorists obtain such a large follow-up online. Secondly, we find that manned social media algorithms can exploit the flaws of minimal global rationality at a faster pace than humans. Yet, given that latter algorithms cannot do so on their own, we argue that the Turing Test is still an open game. Specifically, we argue so because state-of-the-art technology can request a service to be supplied (e.g., Google Duplex) but cannot operate direct sales. This constraint of state-of-the-art technology is linked to its inability to exploit the flaws of global minimal rationality as well as humans can. Importantly, we show that if algorithms were able to do so, the involved sociopolitical risk would be high. Therefore, we argue that only some form of regulation over state-of-the-art technology can prevent and reduce such sociopolitical risks. -/- In case you want a copy of this dissertation, please email me.

As part of our exploration of a new conceptual framework for an economy that works for 100% of humanity, this conceptual paper asks why all talk about the purpose of organizations seems to suffer from a certain bias, namely the bias of scarcity, and how this myth of scarcity influences our understanding of corporate responsibility. The mainstream understanding of corporate purpose always contains partly normative and partly functional aspects designed to cope with the purported problem of scarcity. According (...) to economic and CSR reasoning, this bias concerning the purpose of business organizations triggers two quite distinct understandings of the essence of corporate responsibility. The economic view interprets it as responsibility towards the company, while CSR and business ethics argue that it reflects, or at least ought to reflect, a broader responsibility towards society. To overcome this responsibility gap, we need to affect a paradigm shift in economic reasoning, a shift which reconciles economic responsibility on the micro-level logic of raising profit with the greater demands of the meso, macro, and supra levels. Only then do we obtain a truly meaningful lever for changing real-world business practice from within the micro-logics of running a corporation. This paradigm shift requires a different mental model - a model of resource growth and natural abundance, rather than of scarcity - on the part of both economists and business ethicists. It can be labeled the economic model of future viability. This paper develops a conceptual argument for a future viable model of business practice which, first and foremost, takes seriously the need for the kind of micro-level decision-making which keeps individual organizations afloat, but which also, and crucially, delivers a solution for future viable business models and business behavior which breaks the apparent downward spiral of modern wealth creation, i.e. the spiral of continuous acceleration, disruption, concentration and resource exploitation, and which, thirdly, delivers a proper definition of purpose which can be applied in measurement systems which are free of biased assumptions of scarcity.

We propose a theoretical model to explain the usage of time-inconsistent behavior as a strategy to exploit others when reputation and trust have secondary effects on the economic outcome. We consider two agents with time-consistent preferences exploiting common resources. Supposing that an agent is believed to have time-inconsistent preferences with probability p, we analyze whether she uses this misinformation when she has the opportunity to use it. Using the model originally provided by Levhari and Mirman (Bell J Econ 11(1):322–334, 1980), (...) we determine the optimal degree of present bias that the agent would like to have while pretending to have time-inconsistent preferences and we provide the range of present-bias parameter under which deceiving is optimal. Moreover, by allowing the constant relative risk aversion class of utility form, we characterize the distinction between pretending to be naive and sophisticated. (shrink)

Decision making in any brain is imperfect and costly in terms of time and energy. Operating under such constraints, an organism could be in a position to improve performance if an opportunity arose to exploit informative patterns in the environment being searched. Such an improvement of performance could entail both faster and more accurate (i.e., reward-maximizing) decisions. The present study investigated the extent to which human participants could learn to take advantage of immediate patterns in the spatial arrangement of serially (...) presented foods such that a region of space would consistently be associated with greater subjective value. Eye movements leading up to choices demonstrated rapidly induced biases in the selective allocation of visual fixation and attention that were accompanied by both faster and more accurate choices of desired goods as implicit learning occurred. However, for the control condition with its spatially balanced reward environment, these subjects exhibited preexisting lateralized biases for eye and hand movements (i.e., leftward and rightward, respectively) that could act in opposition not only to each other but also to the orienting biases elicited by the experimental manipulation, producing an asymmetry between the left and right hemifields with respect to performance. Potentially owing at least in part to learned cultural conventions (e.g., reading from left to right), the findings herein particularly revealed an intrinsic leftward bias underlying initial saccades in the midst of more immediate feedback-directed processes for which spatial biases can be learned flexibly to optimize oculomotor and manual control in value-based decision making. The present study thus replicates general findings of learned attentional biases in a novel context with inherently rewarding stimuli and goes on to further elucidate the interactions between endogenous and exogenous biases.

��This paper investigates how an evolutionary al- gorithm with an indirect encoding exploits the property of phenotypic regularity, an important design principle found in natural organisms and engineered designs. We present the first comprehensive study showing that such phenotypic regularity enables an indirect encoding to outperform direct encoding con- trols as problem regularity increases. Such an ability to produce regular solutions that can exploit the regularity of problems is an important prerequisite if evolutionary algorithms are to scale to high-dimensional real-world (...) problems, which typically contain many regularities, both known and unrecognized. The indirect encoding in this case study is HyperNEAT, which evolves artificial neural networks (ANNs) in a manner inspired by concepts from biological development. We demonstrate that, in contrast to two direct encoding controls, HyperNEAT produces both regular behaviors and regular ANNs, which enables HyperNEAT to significantly outperform the direct encodings as regularity increases in three problem domains. We also show that the types of regularities HyperNEAT produces can be biased, allowing domain knowledge and preferences to be injected into the search. Finally, we examine the downside of a bias toward regularity. Even when a solution is mainly regular, some irregularity may be needed to perfect its functionality. This insight is illustrated by a new algorithm called HybrID that hybridizes indirect and direct encodings, which matched HyperNEAT’s performance on regular problems yet outperformed it on problems with some irregularity. HybrID’s ability to improve upon the performance of HyperNEAT raises the question of whether indirect encodings may ultimately excel not as stand-alone algorithms, but by being hybridized with a further process of refinement, wherein the indirect encoding produces patterns that exploit problem regu-.

In this volume of Leys Lectures, the third collection of Wayne Leys Memorial Lectures, six distinguished essayists demonstrate the relevance of ethics to contemporary concerns by constructively exploring major ethical issues deeply embedded in our society. The essays, written by noted scholars Tom Regan, Carol C. Gould, James Rachels, James P. Sterba, Louis P. Pojman, and David L. Norton, focus on issues of feminism, the exploitation of animals, economic injustice, racial prejudice, naive moral relativism, and the failure of public (...) education. _Tom Regan_ and _Louis P. Pojman_ both address the issue of animal rights. Regan directs his attention to an ethic-of-care feminism, which contends that the ideology of male superiority—not only to women but to all creatures—must be destroyed. By means of a "consistency argument," he extends ethic-of-care feminism to the treatment of animals, insisting that we must not permit to be done to animals "in the name of science" what we would not allow to be done to human beings. Pojman, on the other hand, addresses the question of animal rights through a critical analysis of seven theories of the moral status of animals, arguing that while animals have no natural "rights" since they are unable to enter into contracts, they do deserve to be treated kindly. In his view, much animal research could be abandoned without significant loss. What rethinking of democracy in terms of freedom and equality is required by economic justice? _Carol C. Gould_ offers an answer to this question by arguing that economic justice requires that workers control the production process as well as the distribution process. Such justice would provide the basis of "positive freedom" as self-development without ignoring the importance of the absence of constraints. Taking racial prejudice as his paradigm, _James Rachels_ explores the deeper meaning of prejudice and what equality of treatment involves. Noting the subtlety of prejudicial reasoning, he examines how stereotypes, unconscious bias, and the human tendency toward rationalization make it difficult even for people of good will to prevent prejudice from influencing their actions. _James P. Sterba_ invites the reader to consider a different and more general problem of how to persuade people to act for moral reasons. To accomplish this aim he shows morality to be a requirement of rationality and "the welfare liberal ideal" to be a fusion of the practical ends of five ideals—liberty, fairness, common good, androgyny, and equality. For _David L. Norton_, one of our most pressing problems is the failure of our educational system. The system fails to enable students to make wise "life-shaping" choices involving vocation, marriage, children, and friendship. In order to make good choices, human beings must live and work in an environment that provides experiences that authenticate "personal truths" indispensable to worthy living. These personal truths include direct acquaintance with vocational alternatives and participation in actual service to others. Collectively, these essays bring into sharp focus the urgent moral issues confronting our society and the need for ongoing discussion and examination of these issues in order to gain deeper understanding of and possible solutions to the problems they present.

This paper considers how surprise (or its lack) can be cast as a metacognitive signal with an adaptive function in learning new knowledge and revising belief networks. It reviews the phenomena that may hinder this signal (e.g., hindsight bias) and argues for its extrinsic exploitation in instructional and educational contexts by educators, journalists and parents, who might train learners to internalize the use of surprise to drive explanation‐based learning.

While the simple historical view has pictured the Lysenko controversy as an uninterrupted series of Lysenko's victories-beginning with the 1936 discussion, and culminating in the infamous August 1948 meeting of the Lenin All-Union Academy of Agricultural Sciences, when genetics was officially abolished in the Soviet Union-it was certainly more complex, as recognized by such serious historians as David Joravsky and Mark Adams. As we have seen, the roles the competitors assumed in 1945–47 were the reverse of those they assumed in (...) the 1930s: the geneticists managed to gain the offensive, and Lysenko was forced to defend his position.This episode suggests that the Communist Party leadership probably did not have a special bias against genetics, nor a particular preference toward Lysenko at that time. The actual decisions of the Party apparatus on particular science policies were based upon the current priorities of general foreign and domestic policies, rather than upon an “orthodox Party line” in esoteric scientific questions. It is clear and has been recognized by some historians that the Soviet scientific community was not a passive, monolithic object of the manipulation, control, and repression exercised by the Communist Party leadership; various groups within the Soviet scientific community actively exploited every opportunity provided by the Party's policies to achieve their own objectives.The Lysenko controversy illustrates the profound impact of international events on Soviet science and suggests that its history cannot be understood as a result of exclusively domestic affairs, but should be explicated within a broader framework of interaction between Soviet domestic and international policies and between the Soviet and Western scientific communities. As we have seen, one of the major causes of the geneticists' success in the postwar struggle with Lysenkoists was the shift of Soviet foreign policies toward internationalism stimulated by the wartime alliance between the “Big Three.” This suggests that the so-called “death” of genetics in the Soviet Union in August 1948 was also the result of another dramatic shift in the international situation: the climax of the Cold War confrontation between former allies in the summer of 1948, which marked the final division of postwar Europe and the world into two opposing camps, East and West.

This paper argues that the form of explanation at issue in the hard problem of consciousness is scientifically irrelevant, despite appearances to the contrary. In particular, it is argued that the 'sense of understanding' that plays a critical role in the form of explanation implicated in the hard problem provides neither a necessary nor a sufficient condition on satisfactory scientific explanation. Considerations of the actual tools and methods available to scientists are used to make the case against it being a (...) necessary condition, and work by J.D. Trout that exploits psychological research on the hindsight and overconfidence biases is used to show that it is not a sufficient condition. It is argued, however, that certain intellectual and moral concerns give us good reason to still try to meet the hard problem's explanatory challenge, despite its extrascientific nature. (shrink)
