Positive polarity items (PPIs) are generally thought to have the boring property that they cannot scope below negation. The starting point of the paper is the observation that their distribution is significantly more complex; specifically, someone/something-type PPIs share properties with negative polarity items (NPIs). First, these PPIs are disallowed in the same environments that license yet type NPIs; second, adding any NPI-licenser rescues the illegitimate constellation. This leads to the conclusion that these PPIs have the combined properties (...) of yet-type and ever-type NPIs: what appears to be a prohibition is nothing but “halfway licensing”. The paper goes on to propose a unification of the analyses of rescuable PPIs, NPIs, and negative concord, and questions the grounding of polarity sensitivity in the scalar or the referential semantics of the items involved.

Deontic necessity modals (e.g. 'have to', 'ought to', 'must', 'need to', 'should', etc.) seem to vary in how they interact with negation. According to some accounts, what forces modals like 'ought' and 'should' to outscope negation is their polarity sensitivity -- modals that scope over negation do so because they are positive polarity items. But there is a conflict between this account and a widely assumed theory of if-clauses, namely the restrictor analysis. In particular, the conflict arises (...) for constructions containing a bound pronoun in the if-clause. This note spells out the core conflict. (shrink)

Ruwet observed that subjunctives indicate a discontinuity between action and will, typically resulting in a disjoint reference effect known as obviation (unacceptable "Je veux que je parte"). In a certain set of cases, however, the attitude-holder can felicitously bind the pronominal subject of the subjunctive clause (exemption from obviation). This seminar handout examines the phenomenon in Hungarian, with additional data from Russian, Polish, and Romanian.

The scalar approach to negative polarity item (NPI) licensing assumes that NPIs are allowable in contexts in which the introduction of the NPI leads to proposition strengthening (e.g., Kadmon & Landman 1993, Krifka 1995, Lahiri 1997, Chierchia 2006). A straightforward processing prediction from such a theory is that NPI’s facilitate inference verification from sets to subsets. Three experiments are reported that test this proposal. In each experiment, participants evaluated whether inferences from sets to subsets were valid. Crucially, we (...) manipulated whether the premises contained an NPI. In Experiment 1, participants completed a metalinguistic reasoning task, and Experiments 2 and 3 tested reading times using a self-paced reading task. Contrary to expectations, no facilitation was observed when the NPI was present in the premise compared to when it was absent. In fact, the NPI significantly slowed down reading times in the inference region. Our results therefore favor those scalar theories that predict that the NPI is costly to process (Chierchia 2006), or other, nonscalar theories (Giannakidou 1998, Ladusaw 1992, Postal 2005, Szabolcsi 2004) that likewise predict NPI processing cost but, unlike Chierchia (2006), expect the magnitude of the processing cost to vary with the actual pragmatics of the NPI.

The de Morgan laws characterize how negation, conjunction, and disjunction interact with each other. They are fundamental in any semantics that bases itself on the propositional calculus/Boolean algebra. This paper is primarily concerned with the second law. In English, its validity is easy to demonstrate using linguistic examples. Consider the following: (3) Why is it so cold in here? We didn’t close the door or the window. The second sentence is ambiguous. It may mean that I suppose we did not (...) close the door or did not close the window, but I am not sure which. This `I am not sure which’ reading is irrelevant to us because it has disjunction scoping over negation. But the sentence may equally well mean (and indeed this is the preferred reading) that we didn’t close the door and did not close the window. This `neither’ reading bears out de Morgan law (2).

Predictable polarization is everywhere: we can often predict how people’s opinions, including our own, will shift over time. Extant theories either neglect the fact that we can predict our own polarization, or explain it through irrational mechanisms. They needn’t. Empirical studies suggest that polarization is predictable when evidence is ambiguous, that is, when the rational response is not obvious. I show how Bayesians should model such ambiguity and then prove that—assuming rational updates are those which obey the value of evidence—ambiguity (...) is necessary and sufficient for the rationality of predictable polarization. The main theoretical result is that there can be a series of such updates, each of which is individually expected to make you more accurate, but which together will predictably polarize you. Polarization results from asymmetric increases in accuracy. This mechanism is not only theoretically possible, but empirically plausible. I argue that cognitive search—searching a cognitively accessible space for a particular item—often yields asymmetrically ambiguous evidence, I present an experiment supporting its polarizing effects, and I use simulations to show how it can explain two of the core causes of polarization: confirmation bias and the group polarization effect.

An electronic poster from "Polarity from Different Perspectives," New York University, 2005. The authors present an experiment that investigated to what extent six negative polarity items (slept a wink, in ages, ever, much, at all, and yet) are licensed by 9 potential licensers.

People seem more divided than ever before over social and political issues, entrenched in their existing beliefs and unwilling to change them. Empirical research on mechanisms driving this resistance to belief change has focused on a limited set of well-known, charged, contentious issues and has not accounted for deliberation over reasons and arguments in belief formation prior to experimental sessions. With a large, heterogeneous sample (N = 3,001), we attempt to overcome these existing problems, and we investigate the causes and (...) consequences of resistance to belief change for five diverse and less contentious socio-political issues. After participants chose initially to support or oppose a given socio-political position, they were provided with reasons favoring their chosen position (affirming reasons), reasons favoring the other, unchosen position (conflicting reasons), or all reasons for both positions (reasons for both sides). Our results indicate that participants are more likely to stick with their initial decisions than to change them no matter which reasons are considered, and that this resistance to belief change is likely due to a motivated, biased evaluation of the reasons to support their initial beliefs (prior-belief bias). More specifically, they rated affirming reasons more favorably than conflicting reasons—even after accounting for reported prior knowledge about the issue, the novelty of the reasons presented, and the reported strategy used to make the initial decision. In many cases, participants who did not change their positions tended to become more confident in the superiority of their positions after considering many reasons for both sides. (shrink)

Public health care interventions—regarding vaccination, obesity, and HIV, for example—standardly take the form of information dissemination across a community. But information networks can vary importantly between different ethnic communities, as can levels of trust in information from different sources. We use data from the Greater Pittsburgh Random Household Health Survey to construct models of information networks for White and Black communities--models which reflect the degree of information contact between individuals, with degrees of trust in information from various sources correlated with (...) positions in that social network. With simple assumptions regarding belief change and social reinforcement, we use those modeled networks to build dynamic agent-based models of how information can be expected to flow and how beliefs can be expected to change across each community. With contrasting information from governmental and religious sources, the results show importantly different dynamic patterns of belief polarization within the two communities. (shrink)

The present work posits that social motives, particularly status seeking in the form of moral grandstanding, are likely at least partially to blame for elevated levels of affective polarization and ideological extremism in the U.S. In Study 1, results from both undergraduates (N = 981; Mean age = 19.4; SD = 2.1; 69.7% women) and a cross-section of U.S. adults matched to 2010 census norms (N = 1,063; Mean age = 48.20, SD = 16.38; 49.8% women) indicated that prestige-motived grandstanding (...) was consistently and robustly related to more extreme ideological views on a variety of issues. In Study 2, results from a weighted, nationally-representative cross-section of U.S. adults (N = 2,519; Mean age = 47.5, SD = 17.8; 51.4% women) found that prestige motivated grandstanding was reliably related to both ideological extremism and affective polarization.

Rarely does research in the history and philosophy of science lead to new empirical results, but that is exactly what has happened in one of the essays of this special issue: Rang and Grebe-Ellis have developed new experimental techniques to perform measurements Goethe proposed 217 years ago. These measurements fit neatly with Goethe’s idea of polarity—his complementary spectrum is not only an optical, but also a thermodynamical counterpart of Newton’s spectrum. I use the new measurements, firstly, to argue against (...) the asymmetries between light and darkness posited by Lyre and Schreiber; and, secondly, to explicate the alternative theory that Goethe had introduced to urge scientific pluralism. In my replies to exegetical criticism by Böhler, Hampe and Zemplén, I show that the main goal of Goethe’s Farbenlehre was indeed to expose symmetries between light and darkness. Furthermore, I argue that it is worthwhile to focus on the experiments, arguments and hypotheses of the Farbenlehre, and not merely on rhetorical, narrative or stylistical aspects, as Böhler and Hampe would have it. Goethe’s criticism of Newton is often dismissed, but it is in fact surprisingly relevant today. (shrink)

The study examined the differential item functioning (DIF) of 2018 Basic Education Certificate examination (BECE) in Mathematics tests of National Examination Council (NECO) and BECE of Akwa Ibom State government in Nigeria. The invariance in the tests with regards to sex was considered using Item Response Theory (IRT) approach. The study area was Akwa Ibom state of Nigeria having a student population of 58,281 for the examination. The sample was made of up 3810 students drawn through a multi-stage (...) sampling approach. The multidimensional IRT (MIRT) package implemented in R-programming language software was applied in analyzing the data. The findings reveal that BECE of NECO displayed 23(38.3%) DIF items while BECE of Akwa Ibom State had 37 (61.7%) DIF items in terms of sex. The findings also revealed that, in the two examinations, more items favoured the male candidates more than the female candidates in terms of performance. It was recommended that IRT model should be adopted by test developers to determine item parameters for selection of good items to ensure quality of items before administration. Test equating of students who write equivalent form examinations conducted by different examining bodies was also recommended for admission and placement of candidates to determine actual group differences in performance. The study posits that research on Differential Item Functioning is inconclusive, so should be encouraged. (shrink)

Much of the literature from political psychology has focused on the negative traits that are positively associated with affective polarization—e.g., animus, arrogance, distrust, hostility, and outrage. Not as much attention has been focused on the positive traits that might be negatively associated with polarization. For instance, given that people who are intellectually humble display greater openness and less hostility towards conflicting viewpoints (Krumrei-Mancuso & Rouse, 2016; Hopkin et al., 2014; Porter & Schumann, 2018), one might reasonably expect them to (...) be less polarized. -/- We ran two studies designed to explore the relationship between various forms of humility and polarization. Our chief finding is that people who value humility are prone to what we are calling epistemic polarization—that is, judging the epistemic traits of contrapartisans negatively—which in turn plays a role in polarization more generally. Not only are contrapartisans deemed to have the wrong moral and political beliefs, they are also viewed as less humble and more arrogant, close-minded, and irrational. This makes matters even worse when it comes to the growing partisan divide. In light of our findings, we believe that the novel concept of epistemic polarization that we introduce is a promising target for further investigation. (shrink)

There have been many discussions recently from philosophers, cognitive scientists, and psychologists about group polarization, with online and social media environments in particular receiving a lot of attention, both because of people's increasing reliance on such environments for receiving and exchanging information and because such environments often allow individuals to selectively interact with those who are like-minded. My goal here is to argue that the group epistemologist can facilitate understanding the kinds of factors that drive group polarization in a way (...) that has been overlooked by the existing research. Specifically, I argue that polarization can occur in part because of the ways that members of a group treat the group itself (as opposed to an individual member within that group) as a source of information, and in doing so makes their own position, as well as that of the group, more extreme. I refer to this as a structural factor in driving polarization, and argue that such factors can contribute to explanations of polarization that occurs specifically in an important subset of groups, namely online and social media groups in which little is known about other members within the group, what I refer to as anonymous, semi-anonymous and pseudonymous (ASAP) groups.

This paper examines distinctive discourse properties of preposed negative 'yes/no' questions (NPQs), such as 'Isn’t Jane coming too?'. Unlike with other 'yes/no' questions, using an NPQ '∼p?' invariably conveys a bias toward a particular answer, where the polarity of the bias is opposite of the polarity of the question: using the negative question '∼p?' invariably expresses that the speaker previously expected the positive answer p to be correct. A prominent approach—what I call the context-management approach, developed most (...) extensively by Romero and Han (2004)—attempts to capture speaker expectation biases by treating NPQs fundamentally as epistemic questions about the proper discourse status of a proposition. I raise challenges for existing context-managing accounts to provide more adequate formalizations of the posited context-managing content, its implementation in the compositional semantics and discourse dynamics, and its role in generating the observed biases. New data regarding discourse differences between NPQs and associated epistemic modal questions are introduced. I argue that we can capture the roles of NPQs in expressing speakers’ states of mind and managing the discourse common ground without positing special context-managing operators or treating NPQs as questions directly about the context. I suggest that we treat the operator introduced with preposed negation as having an ordinary semantics of epistemic necessity, though lexically associated with a general kind of endorsing use observed with modal expressions. The expressive and context-managing roles of NPQs are explained in terms of a general kind of discourse-oriented use of context-sensitive language. The distinctive expectation biases and discourse properties observed with NPQs are derived from the proposed semantics and a general principle of Discourse Relevance. (shrink)

In this paper, I use an example from the history of philosophy to show how independently defining each side of a pair of contrary predicates is apt to lead to contradiction. In the Euthyphro, piety is defined as that which is loved by some of the gods while impiety is defined as that which is hated by some of the gods. Socrates points out that since the gods harbor contrary sentiments, some things are both pious and impious. But “pious” and (...) “impious” are contrary predicates; they cannot simultaneously characterize the same thing. Euthyphro changes his definition, but the problem of recognizing emotional ambivalence is only side-stepped. I go on to show how contemporary philosophers run into a similar problem. According to Prinz, something is good if and only if we harbor positive sentiments towards it and bad if and only if we harbor negative sentiments towards it. Thus, if we are ambivalent towards something (if we harbor both positive and negative sentiments towards it), then it is both good and bad. Like “pious” and “impious”, “good” and “bad” are contraries. Next, according to the fitting-attitude theory first elaborated by Brentano and favored by contemporary meta-ethicists like Blackburn, Brandt, Ewing, Garcia, Gibbard, McDowell, and Wiggins, something is good if and only if it is a fitting (appropriate) object of approbation, and something is bad if and only if it is a fitting (appropriate) object of disapprobation. I argue that moral ambivalence is sometimes appropriate, i.e., that the correct response to some things is to both love and hate them. Hence, according to the fitting-attitudes theory, some things are both good and bad. I conclude by discussing a variety of ways in which the problem of ambivalence may be solved, suggesting that attitudes of approbation and disapprobation be further individuated by the reasons for them.

Does algorithmic political bias contribute to an entrenchment and polarization of political positions? Franke argues that it may do so because the bias involves classifications of people as liberals, conservatives, etc., and individuals often conform to the ways in which they are classified. I provide a novel example of this phenomenon in human–computer interactions and introduce a social psychological mechanism that has been overlooked in this context but should be experimentally explored. Furthermore, while Franke proposes that algorithmic political classifications entrench (...) political identities, I contend that they may often produce the opposite result. They can lead people to change in ways that disconfirm the classifications. Consequently and counterintuitively, algorithmic political bias can in fact decrease political entrenchment and polarization. (shrink)

The additive presupposition of particles like "too"/"even" is uncontested, but usually stipulated. This paper proposes to derive it based on two properties. (i) "too"/"even" is cross-linguistically focus-sensitive, and (ii) in many languages, "too"/"even" builds negative polarity items and free-choice items as well, often in concert with other particles. (i) is the source of its existential presupposition, and (ii) offers clues regarding how additivity comes about. (i)-(ii) together demand a sparse semantics for "too/even," one that can work with different kinds (...) of alternatives (focus, subdomain, scalar) and invoke suitably different further operators.

In this paper I present an overview of the doctrine known as Positive Aesthetics regarding aesthetic judgements about nature. According to this view, all pristine nature is always beautiful and, generally, although not necessarily, human intervention tends to introduce ugliness in nature. One of the strong practical motivations behind this claim is an attempt to ground our reasons to preserve natural environments in aesthetic reasons. Positive Aesthetics has been defended within contrary approaches to nature appreciation such as the (...) cognitivists and the anti-cognitivist. Recently, the possibility of real ugliness in nature has been defended; at the same time, it is argued that the presence of ugly items in nature does not lead necessarily to the idea that they are not aesthetically valuable. Hence, natural ugliness can be a reason to preserve nature. In this sense, the denial of the Positive Aesthetics claim is shown to be compatible with the appeal to aesthetic negative qualities as a source of reasons for preserving natural environments.

Purpose – The goal of this study is to examine the factors (e.g. enjoyment, skills, challenge, telepresence and flow) that influence players’ purchase intention toward Dota 2 virtual in-game as well as examine the effect of flow toward purchase intention of Dota 2 through the critical mechanism (i.e. continuous intention). Notably, the analysis of the moderating role of enjoyment of buying on the relation of (a) flow and purchase intention of Dota 2 in-game, as well as (b) between flow continuous (...) intention and finally (c) between continuous intention purchase intention of Dota 2. -/- Design/methodology/approach – The data were gained from 331 users using Google Forms and posted to respondents on social media platforms and forums such as Facebook and Reddit, as these websites have the closest reach to gamers. -/- Findings – The study revealed that enjoyment, skill, challenge and telepresence have a positive effect on flow. Also, the flow was significantly related to purchase intention. The continuous intention has significantly mediated the relationship between flow and purchase intention. Importantly, this study found that the moderating role of buying enjoyment increases the relationship between flow and purchase intention (H7a) and between continuous intention and purchase intention (H7c). In contrast, the moderating role of buying enjoyment on the relationship between flow and continuous intention (H7b) was not supported. Hence, this study sheds new light on the notable Dota 2 in-game and continuous intention purchase intention of the users. -/- Originality/value – In response, this study’s main research question can be highlighted on testing how enjoyment, skills, challenge, telepresence, in-game virtual items influence purchasing intention when the enjoyment of buying moderates the proposed relationship? Therefore, this study aims to examine the significant elements like enjoyment, skills, challenge telepresence toward flow, and subsequently, the effect of flow toward purchase intention of Dota 2 in-game through continuous intention as a key mechanism which is urgently needed to minimize the gap in-game virtual items literature. Significantly, this study also intends to explore the contingent role of enjoyment of buying on the relation of flow and purchase intention of Dota-2 ingame, as well as between flow and continuous intention and finally between continuous intention and purchase intention.

We investigate adverbial agreement in Sandəmarkesə (S. Marco in Lamis, Apulia) proposing phase-bound, local agreement relations, reducible to coordination, as in past and absolute participial constructions, suggesting a copulaless analysis where arguments are subjects in a small clause. With disjunct nominals with matching φ-features, the adverb agrees separately with each part in the set, otherwise resulting in ‘non-agreeing’ forms, which we test also with negative polarity items (niʃun-, ‘nobody’ and nentə, ‘nothing’). With fragment answers, the negation scopes over adverbs (...) agreeing with the two proposed topics: matching of the φ-features of both nouns values the negative operator with the same features. In fronted adverbs, agreement occurs when the question contains overt coordinated arguments, elements continuing a chain, and if coordinated arguments have matching φ-features. In agreement in topical contexts with fronted adverbs, agreement occurs with the aboutness-shift topic closely preceding them, rather than with the embedded direct object. (shrink)

This paper uses a partially ordered set of syntactic categories to accommodate optionality and licensing in natural language syntax. A complex but well-studied data set pertaining to the syntax of quantifier scope and negative polarity licensing in Hungarian is used to illustrate the proposal.

The paper highlights that the main ideas can be implemented in different grammar formalisms, and discusses in detail an implementation where the partial ordering on categories is (...) given by the derivability relation of a calculus with residuated and Galois-connected unary operators.

Thick terms and concepts, such as honesty and cruelty, are at the heart of a variety of debates in philosophy of language and metaethics. Central to these debates is the question of how the descriptive and evaluative components of thick concepts are related and whether they can be separated from each other. So far, no empirical data on how thick terms are used in ordinary language has been collected to inform these debates. In this paper, we present the first empirical (...) study, designed to investigate whether the evaluative component of thick concepts is communicated as part of the semantic meaning or by means of conversational implicatures. While neither the semantic nor the pragmatic view can fully account for the use of thick terms in ordinary language, our results do favour the semanticist interpretation: the evaluation of a thick concept is only slightly easier to cancel than semantically entailed content. We further discovered a polarity effect, demonstrating that how easily an evaluation can be cancelled depends on whether the thick term is of positive or negative polarity. (shrink)

The bi-polar confrontation between the Soviet Union and the USA involved many leading game theorists from both sides of the Iron Curtain: Oskar Morgenstern, John von Neumann, Michael Intriligator, John Nash, Thomas Schelling and Steven Brams from the United States and Nikolay Vorob’ev, Leon A. Petrosyan, Elena B. Yanovskaya and Olga N. Bondareva from the Soviet Union. The formalization of game theory took place prior to the Cold War but the geopolitical confrontation hastened and shaped its evolution. In our article (...) we outline four similarities and differences between Western GT and Soviet GT: 1) the Iron Curtain resulted in a lagged evolution of GT in the Soviet Union; 2) Soviet GT focused more on operations research and issues of centralized planning; 3) the contemporary Western view on Soviet GT was biased and Soviet contributions, including works on dynamic stability, non-emptiness of the core and many refinements, suggest that Soviet GT was able to catch up to the Western level relatively fast; 4) international conferences, including Vilnius, 1971, fostered interaction between Soviet game theorists and their Western colleagues. In general, we consider the Cold War to be a positive environment for GT in the West and in the Soviet Union. (shrink)

A set of visual search experiments tested the proposal that focused attention is needed to detect change. Displays were arrays of rectangles, with the target being the item that continually changed its orientation or contrast polarity. Five aspects of performance were examined: linearity of response, processing time, capacity, selectivity, and memory trace. Detection of change was found to be a self-terminating process requiring a time that increased linearly with the number of items in the display. Capacity for orientation (...) was found to be about 5 items, a value comparable to estimates of attentional capacity. Observers were able to filter out both static and dynamic variations in irrelevant properties. Analysis also indicated a memory for previously-attended locations. These results support the hypothesis that the process needed to detect change is much the same as the attentional process needed to detect complex static patterns. Interestingly, the features of orientation and polarity were found to be handled in somewhat different ways. Taken together, these results not only provide evidence that focused attention is needed to see change, but also show that change detection itself can provide new insights into the nature of attentional processing.

The limited access to public secondary education in rural regions of Haiti has impacted children who want to pursue their education beyond the primary level. This generic qualitative study aimed to explore the perceptions of informed Haitian educators and other educators who were knowledgeable about the lack of access to public secondary education in rural Haiti, specifically through the framework of polarities of democracy theory. Data were gathered by conducting semistructured interviews with 20 educators who were situated in both Haiti (...) and the United States. NVivo 14 was used to organize, code, and analyze the data. Thematic analysis revealed three themes: (a) the government prioritizes political and personal interests over rural residents’ education, (b) disparities need to be reduced between urban and rural areas, and (c) a revolution in education is needed to build more public secondary schools for rural residents. Public policy recommendations included investing in training rural individuals to create a database of academics who can meet local students’ educational demands. Positive social change can occur by enhancing governmental services, implementing strategies to revitalize the agricultural sector in rural regions, and promoting active participation of rural residents in shaping the design of public schools to ensure effective secondary education for their children.

Studying the psychology behind the purchase of eco-friendly products and second-hand items can offer valuable insights to promote sustainable consumer behavior. This paper examines factors influencing Italian consumers’ willingness to pay regarding bio-based clothing and second-hand items. Drawing from data collected from 402 Italian participants, we examine how motivations and socio-demographic factors are associated with willingness to pay in the context of sustainable fashion. Our findings reveal that motivations related to environmental concerns are positively associated with consumers’ willingness to pay (...) higher premiums for bio-based clothing. Higher income and education levels are also associated with the willingness to pay higher premiums. Meanwhile, motivation related to vintage appeal is associated with lower desired discounts for second-hand items, particularly among older consumers. Gender differences also influence discount preferences, with men seeking larger discounts on second-hand clothing compared to women. By providing insights into Italian consumers’ sustainable fashion choices, this study offers implications for businesses, policymakers, and researchers aiming to promote eco-conscious consumption and sustainability in the fashion industry.

Focused attention is needed to perceive change (Rensink et al., 1997; Psychological Science, 8: 368-373) . But how much attentional processing is given to an item? And does this depend on the nature of the task? To answer these questions, "flicker" displays were created, where an original and a modified image continually alternated, with brief blanks between them. Each image was an array of simple figures, half being horizontal and the other half vertical. In half the trials, one of (...) the items changed orientation; in the remainder, all items remained the same. Observers were asked to detect whether a change was occurring in each trial. -/- Within-observer comparisons for different shapes of items yielded two classes of speed: relatively fast search (50 ms/item) for simple lines, and slower search (90 ms/item) for compound figures made of two or more lines. Evidently, more processing was given to compound figures, even though shape was irrelevant to the task. A similar set of experiments asked observers to detect changes in contrast polarity. Here, no differences were found for different shapes, indicating that geometric information is not processed as much when the task involves only nongeometric properties. (shrink)

The pejorative connotation often associated with the ordinary language meaning of “conspiracy theory” does not only stem from a conspiracy theory’s being about a conspiracy, but also from a conspiracy theory’s being regarded as a particular kind of theory. I propose to understand conspiracy theory-induced polarization in terms of disagreement about the correct epistemic evaluation of ‘theory’ in ‘conspiracy theory’. By framing the positions typical in conspiracy theory-induced polarization in this way, I aim to show that pejorative conceptions of ‘conspiracy (...) theory’ are problematic for research open to the possibility of finding depolarization strategies. That is, because they preclude constructive engagement with the epistemic norms governing (the rationales foundational of) belief in conspiracy theories. (shrink)

This paper argues for the existence of a fourth positive generic value relation that can hold between two items beyond ‘better than’, ‘worse than’, and ‘equally good’: namely ‘on a par’.

I present a formal theory of the logic and aboutness of imagination. Aboutness is understood as the relation between meaningful items and what they concern, as per Yablo and Fine’s works on the notion. Imagination is understood as per Chalmers’ positive conceivability: the intentional state of a subject who conceives that p by imagining a situation—a configuration of objects and properties—verifying p. So far aboutness theory has been developed mainly for linguistic representation, but it is natural to extend it (...) to intentional states. The proposed framework combines a modal semantics with a mereology of contents: imagination operators are understood as variably strict quantifiers over worlds with a content-preservation constraint.

Social epistemologists should be well-equipped to explain and evaluate the growing vulnerabilities associated with filter bubbles, echo chambers, and group polarization in social media. However, almost all social epistemology has been built for social contexts that involve merely a speaker-hearer dyad. Filter bubbles, echo chambers, and group polarization all presuppose much larger and more complex network structures. In this paper, we lay the groundwork for a properly social epistemology that gives the role and structure of networks their due. In particular, (...) we formally define epistemic constructs that quantify the structural epistemic position of each node within an interconnected network. We argue for the epistemic value of a structure that we call the (m,k)-observer. We then present empirical evidence that (m,k)-observers are rare in social media discussions of controversial topics, which suggests that people suffer from serious problems of epistemic vulnerability. We conclude by arguing that social epistemologists and computer scientists should work together to develop minimal interventions that improve the structure of epistemic networks. (shrink)

Background: The school meals program has multiple objectives of education, nutrition, and value transfer. To ensure achieving the goal, total quality management (TQM) is implemented in the school meals program. Supply chain issues pose significant challenges to TQM implementation in the program execution. Aim: This study aims to examine national and international capacities in supply chain management by analyzing the variety of food items delivered through the school meals program. Methods: The Bayesian Mindsponge Framework, combining the reasoning strengths of Mindsponge (...) Theory and inference advantages of Bayesian analysis, was employed on a dataset of 126 government representatives who manage large-scale school meal programs in 126 different countries. Results: Findings showed that the method of obtaining supplies, whether through in-kind donations from local, regional, national sources, or national food reserves and purchasing from neighboring or distant countries, had a significant positive association with the variety of food items included in school meals or snacks. Conversely, obtaining supplies in-kind from neighboring or distant countries had a significant negative association with the food variety. Additionally, purchasing supplies from local, regional, or national food reserves had an unclear association with the food variety. Conclusions: Findings underscore the importance of supporting the World Bank and World Food Programme’s recommendation to rely more on local resources and capacities. Enhancing supply chain management at the national level is crucial for developing a long-term and sustainable school meals program. (shrink)

The importance of addressing the existential threat to humanity, climate change, has grown remarkedly in recent years while conflicting views and interests in societies exist. Therefore, climate change agendas have been weaponized to varying degrees, ranging from the international level between countries to the domestic level among political parties. In such contexts, climate change agendas are predominantly driven by political or economic ambitions, sometimes unconnected to concerns for environmental sustainability. Consequently, it can result in an environment that fosters antagonism and (...) disputes over power and position and increases the risk of prolonged confrontations, hindering the collective global efforts to mitigate and adapt to climate change. Through the current discourse, we aim to provide a preliminary definition of the weaponization of climate change and environmental degradation and examine its risks and consequences on international relations, political dynamics, public perception, and the comprehensive integrity of climate action. We also recommend embracing a globally coordinated, scientifically substantiated approach to circumvent climate change by building an eco-surplus cultural value system. (shrink)

It’s intuitive to think that (a) the more sure you are of something, the harder it’ll be to change your mind about it, and (b) you can’t be open-minded about something if you’re very sure about it. If these thoughts are right, then, with minimal assumptions, it follows that you can’t be in a good position to both escape echo chambers and be rationally resistant to fake news: the former requires open-mindedness, but the latter is inimical to it. I argue (...) that neither thought is true and that believing them will get us all mixed up. I show that you can be open-minded and have confidently held beliefs, and that beliefs in which you are less sure are not, thereby, more fragile.

One of the most original contributions to the optimism debate of the eighteenth century was put forward by the maverick French Enlightenment thinker, André-Pierre Le Guay de Prémontval, in an essay entitled “General misunderstanding on the question of optimism”. This essay, which seeks to develop a “middle point” between the polarized pro- and anti-optimist positions that characterized the optimism debate, prefigures the development of process or neoclassical theism in important ways. The essay is presented here in English for the first (...) time, along with an analysis of the essay itself and of the context in which it was written. (shrink)

The term 'covert mixed quotation' describes cases in which linguistic material is interpreted in the manner of mixed quotation — that is, used in addition to being mentioned — despite the superficial absence of any commonly recognized conventional devices indicating quotation. After developing a novel theory of mixed quotation, I show that positing covert mixed quotation allows us to give simple and unified treatments of a number of puzzling semantic phenomena, including the projective behavior of conventional implicature items embedded in (...) indirect speech reports and propositional attitude ascriptions, so-called 'c-monsters,' metalinguistic negation, metalinguistic negotiation, and 'in a sense' constructions.

The self-deception debate often appears polarized between those who think that self-deceivers intentionally deceive themselves (‘intentionalists’), and those who think that intentional actions are not significantly involved in the production of self-deceptive beliefs at all. In this paper I develop a middle position between these views, according to which self-deceivers do end up self-deceived as a result of their own intentional actions, but where the intention these actions are done with is not an intention to deceive oneself. This account thus (...) keeps agency at the heart of self-deception, while also avoiding the paradox associated with other agency-centered views. (shrink)

The adequacy of similarity to prototype as an account of categorization in natural concepts was assessed by analyzing the monotonicity of the relation between typicality of an item in a category and the probability of a positive categorization response using data from McCloskey and Glucksberg (1978). The analysis revealed a strong underlying similarity-based threshold curve, with systematic deviations. Further data collection showed that deviations from the curve could be attributed to the effects of unfamiliarity and non-categorial associations on (...) typicality judgments, as well as differences between the perceptual appearance of an item (which tended to boost typicality) and its underlying nature (which tended to boost categorization). The results are discussed in terms of the different presuppositions and task constraints involved in rating typicality as opposed to performing a categorization. (shrink)

It is time to escape the constraints of the Systematics Wars narrative and pursue new questions that are better positioned to establish the relevance of the field in this time period to broader issues in the history of biology and history of science. To date, the underlying assumptions of the Systematics Wars narrative have led historians to prioritize theory over practice and the conflicts of a few leading theorists over the less-polarized interactions of systematists at large. We show how shifting (...) to a practice-oriented view of methodology, centered on the trajectory of mathematization in systematics, demonstrates problems with the common view that one camp straightforwardly “won” over the other. In particular, we critique David Hull’s historical account in Science as a Process by demonstrating exactly the sort of intermediate level of positive sharing between phenetic and cladistic theories that undermines their mutually exclusive individuality as conceptual systems over time. It is misleading, or at least inadequate, to treat them simply as holistically opposed theories that can only interact by competition to the death. Looking to the future, we suggest that the concept of workflow provides an important new perspective on the history of mathematization and computerization in biology after World War II. (shrink)

We live in times of an increasing polarization in which the margins of the political spectrum begin to dominate our social imagination again. While the neoliberal iteration of the capitalist project suggests an extreme individualism as the normative default position, the devastating impact of the globalized economy on many has reignited the pursuit of socialist alternatives. In this constellation, Simmel’s social theory of modernity can be a useful resource to undercut the return of the old battle between opposite economic systems. (...) This paper argues that two kinds of pluralism can be derived from his conceptualization of the social effects of the money economy. In contrast to one-size-fits-all concepts of freedom, Simmel embraces a social pluralism which acknowledges a plurality of cultural spheres as relevant for the self-actualization of modern individuals, attributing different combinations of independence and embeddedness to them. Moreover, he rejects the social extremes of socialism and individualism, since they fail to properly integrate individual freedom into the social whole without undermining it. Instead Simmel gives us the vision of a pluralist economy in which democratic worker’s cooperatives are combined with an overall liberal market to satisfy both the longing for community and the strive for individual distinction.

Jerry Fodor has argued that concept acquisition cannot be a psychological or “rational-causal” process, but can only be a “brute-causal” process of acquisition. This position generates the “doorknob  DOORKNOB” problem: why are concepts typically acquired on the basis of experience with items in their extensions? I argue that Fodor’s taxonomy of causal processes needs supplementation, and characterize a third type: what I call “intelligible-causal processes.” Armed with this new category I present what I regard as a better response than (...) Fodor’s to the doorknob  DOORKNOB problem. (shrink)

This chapter explores the interaction between the moral value and aesthetic value of food, in part by connecting it to existing discussions of the interaction between moral and aesthetic values of art. Along the way, this chapter considers food as art, the aesthetic value of food, and the role of expertise in uncovering aesthetic value. Ultimately this chapter argues against both food autonomism (the view that food's moral value is unconnected to its aesthetic value) and Carolyn Korsmeyer's food moralism (the (...) view that moral flaws can only make food aesthetically worse). Instead, it argues for the position of food immoralism: sometimes a moral flaw can make an item of food aesthetically better. This chapter concludes by drawing out broader implications of this position for discussions on the ethics of food and discussions on the interaction between the moral and aesthetic values of art.

This paper underscores the significance of home management in suicidal mediation especially among undergraduates in the three universities that offer Home Management in the Southeastern geopolitical zone in Nigeria. The Universities include, University of Nigeria, Nsukka, Michael Okpara University of Agriculture, Umudike, and Ebonyi State University, Abakaliki. The study adopts a descriptive survey design. The population comprises 173 respondents. This is made up of 126 students and 47 lecturers chosen from the universities. The entire populations were used as the sample (...) of the study because of the manageable size. A 27-item questionnaire entitled, Questionnaire on Home Management Suicidal Mediation (QHMSM) was deployed to elicit data from the respondents. The instrument was validated by three experts. The instrument was subjected to Cronbach’s Alpha reliability method to determine the internal consistency which yielded a coefficient of 0.91. Data collected were analyzed using mean and standard deviation to answer research questions. The study revealed that provision of a stable environment through active Home Management for a child enables him experience a childhood filled with both love and bond which help to reduce suicidal mediation amongst undergraduates. The study recommends that parents should provide the basic needs of children, as these will boost their morale and prevent instability. Children should be engaged in positive habits and activities so as to reduce incidence of drug abuse and other social vices. (shrink)

The meaning that expressions take on particular occasions often depends on the context in ways which seem to transcend its direct effect on context-sensitive parameters. ‘Truth-conditional pragmatics’ is the project of trying to model such semantic flexibility within a compositional truth-conditional framework. Most proposals proceed by radically ‘freeing up’ the compositional operations of language. I argue, however, that the resulting theories are too unconstrained, and predict flexibility in cases where it is not observed. These accounts fall into this position because (...) they rarely, if ever, take advantage of the rich information made available by lexical items. I hold, instead, that lexical items encode both extension and non-extension determining information. Under certain conditions, the non-extension determining information of an expression e can enter into the compositional processes that determine the meaning of more complex expressions which contain e. This paper presents and motivates a set of type-driven compositional operations that can access non-extension determining information and introduce bits of it into the meaning of complex expressions. The resulting multidimensional semantics has the tools to deal with key cases of semantic flexibility in appropriately constrained ways, making it a promising framework to pursue the project of truth-conditional pragmatics.

Similarity-based cognition is commonplace. It occurs whenever an agent or system exploits the similarities that hold between two or more items—e.g., events, processes, objects, and so on—in order to perform some cognitive task. This kind of cognition is of special interest to cognitive neuroscientists. This paper explicates how similarity-based cognition can be understood through the lens of radical enactivism and why doing so has advantages over its representationalist rival, which posits the existence of structural representations or S-representations. Specifically, it is (...) argued that there are problems both with accounting for the content of S-representations and with understanding how neurally-based structural similarities can work as representations in guiding intelligent behavior. Finally, with these clarifications in place, it is revealed how radical enactivism can commit to an account of similarity-based cognition in its understanding of neurodynamics. (shrink)

This paper empirically investigates whether people’s implicit decision theory is more like causal decision theory or more like a non-causal decision theory (such as evidential decision theory). We also aim to determine whether implicit causalists, without prompting and without prior education, make a distinction that is crucial to causal decision theorists: preferring something _as a news item_ and preferring it _as an object of choice_. Finally, we investigate whether differences in people’s implicit decision theory correlate with differences in their level (...) of _future bias_: the preference for positively valenced events to be located in the future and not the past, and negatively valenced events to be located in the past and not the future. We find that people are overwhelmingly non-causalists. We also find that implicit causalists _do not_ make the distinction between news items and objects of choice, and that there is little to no correlation between people’s future bias and their implicit decision theory. We end by discussing the philosophical upshots of this work. (shrink)

The absence of meaningfulness in life is meaninglessness. But what is the polar opposite of meaningfulness? In recent and ongoing work together with Stephen Campbell and Marcello di Paola respectively, I have explored what we dub ‘anti-meaning’: the negative counterpart of positive meaning in life. Here, I relate this idea of ‘anti-meaningful’ actions, activities, and projects to the topic of death, and in particular the deaths or suffering of those who will live after our own deaths. Connecting this idea (...) of anti-meaning and what happens after our own deaths to recent work by Samuel Scheffler on what he calls ‘the collective afterlife’ and his four reasons to care about future generations, I argue that if we today make choices or have lifestyles that later lead to unnecessarily early deaths and otherwise avoidable suffering of people who will live after we have died, this robs our current choices and lifestyles of some of their meaning, perhaps even making them the opposite of meaningful in the long run.

The study aimed to identify the knowledge management processes and their role in achieving competitive advantage at Al-Quds Open University. The study was based on the descriptive analytical method, and the study population consists of academic and administrative staff in each of the branches of Al-Quds Open University in (Tulkarm, Nablus and Jenin). The researchers selected a sample of the study population by the intentional non-probability method, the size of (70) employees. A questionnaire was prepared and supervised by a number (...) of specialists in order to obtain the results of the study. The study concluded that there is a positive direct relationship, that is, the higher the degree of application of knowledge management processes, the greater the degree of competitive advantage. Knowledge Technology came first with a score of 80.02% on all items. Competitive advantage came second with 81.74%. In the third place came "knowledge generation" where the total score on all paragraphs in this area (78.24%). In the fourth place, "knowledge transfer" (77.21%). "Developing and storing knowledge" came in fifth place (77.13%). "Acquisition of knowledge" came in sixth place (76.45%). Knowledge Organization ranked seventh (74.26%). The study recommended that the university should enable the employees to benefit from the experiences and expertise available to help generate knowledge. The University encourages the creation of knowledge through the system of incentives and open the way for creators to apply their creations and spread and invest in excellence and creativity. The university should design work performance levels based on the integration of knowledge and organize it according to policies that support freedom of research. The need for Palestinian universities to adopt a knowledge management approach. The need to adopt a system of incentives that rewards cognitive efforts, and give workers enough freedom to enable them to apply their knowledge. (shrink)

In the United States, public opinions about climate change have become polarized, with a stark difference in the belief in climate change. Climate change denialism is pervasive among Republicans, especially conservatives, contrasting the high recognition of human-induced climate change issues among Democrats. As the water crisis is closely linked to climate change, the current study aims to examine how the belief in climate change’s impacts on future water supply uncertainty affects water conservation behaviors and whether the effect is conditional on (...) being a Republican. The Bayesian Mindsponge Framework (BMF) analytics was performed on a dataset of 1831 water users in an arid region (Albuquerque, New Mexico). The analysis shows that water users’ belief in climate change’s impacts on future water supply uncertainty positively affects the number of water conservation behaviors they adopt, regardless of whether they are Republicans. Although being a Republican does not significantly negatively moderate the association between climate change belief and water conservation behaviors, the result still underscores the importance of fighting climate change denialism. Otherwise, it will not only hinder the climate change alleviation efforts but also exacerbate the water crisis. Several strategies to reduce climate change denialism are also recommended. (shrink)
