Newton published his deduction of universal gravity in Principia (first ed., 1687). To establish the universality (the particle-to-particle nature) of gravity, Newton must establish the additivity of mass. I call ‘additivity’ the property a body's quantity of matter has just in case, if gravitational force is proportional to that quantity, the force can be taken to be the sum of forces proportional to each particle's quantity of matter. Newton's argument for additivity is obscure. I analyze and assess manuscript versions of (...) Newton's initial argument within his initial deduction, dating from early 1685. Newton's strategy depends on distinguishing two quantities of matter, which I call ‘active’ and ‘passive’, by how they are measured. These measurement procedures frame conditions on the additivity of each quantity so measured. While Newton has direct evidence for the additivity of passive quantity of matter, he does not for that of the active quantity. Instead, he tries to infer the latter from the former via conceptual analyses of the third law of motion grounded largely on analogies to magnetic attractions. The conditions needed to establish passive additivity frustrate Newton's attempted inference to active additivity. (shrink)

This study investigated relationships between inter-class variations in paranormal experience and executive functions. A sample of 516 adults completed self-report measures assessing personal encounter-based paranormal occurrences, executive functions together with Emotion Regulation and Belief in the Paranormal. Paranormal belief served as a measure of convergent validity for experience-based phenomena. Latent profile analysis combined experience-based indices into four classes based on sample subpopulation scores. Multivariate analysis of variance then examined interclass differences. Results revealed that breadth of paranormal experience was associated with (...) higher levels of executive functioning difficulties for General Executive Function, Working Memory, Decision Making, and Belief in the Paranormal. On the Everyday Memory Questionnaire, scores differed on Attention Tracking and Factor 3, but not Retrieval. In the case of the Emotion Regulation Scale, class scores varied on Expressive Suppression, however, no difference was evident on Cognitive Reappraisal. Overall, inter-class comparisons identified subtle differences in executive functions related to experience. Since the present study was exploratory, sampled only a limited subset of executive functions, and used subjective, self-report measures, further research is necessary to confirm these outcomes. This should employ objective tests and include a broader range of executive functions. (shrink)

This paper assessed whether belief in conspiracy theories was associated with a particularly cognitive style (worldview). The sample comprised 223 volunteers recruited via convenience sampling and included undergraduates, postgraduates, university employees and alumni. Respondents completed measures assessing a range of cognitive-perceptual factors (schizotypy, delusional ideation and hallucination proneness) and conspiratorial beliefs (general attitudes towards conspiracist thinking and endorsement of individual conspiracies). Positive symptoms of schizotypy, particularly the cognitive-perceptual factor, correlated positively with conspiracist beliefs. The best predictor of belief in conspiracies (...) was delusional ideation. Consistent with the notion of a coherent conspiratorial mindset, scores across conspiracy measures correlated strongly. Whilst findings supported the view that belief in conspiracies, within the sub-clinical population, was associated with a delusional thinking style, cognitive-perceptual factors in combination accounted for only 32% of the variance.

The present paper examined relationships between schizotypy (measured by the Oxford-Liverpool Inventory of Feelings and Experience; O-LIFE scale brief), belief in the paranormal (assessed via the Revised Paranormal Belief Scale; RPBS) and proneness to statistical bias (i.e., perception of randomness and susceptibility to conjunction fallacy). Participants were 254 volunteers recruited via convenience sampling. Probabilistic reasoning problems appeared framed within both standard and paranormal contexts. Analysis revealed positive correlations between the Unusual Experience (UnExp) subscale of O-LIFE and paranormal belief measures [RPBS (...) full scale, traditional paranormal beliefs (TPB) and new age philosophy]. Performance on standard problems correlated negatively with UnExp and belief in the paranormal (particularly the TPB dimension of the RPBS). Consideration of specific problem types revealed that perception of randomness associated more strongly with belief in the paranormal than conjunction; both problem types related similarly to UnExp. Structural equation modeling specified that belief in the paranormal mediated the indirect relationship between UnExp and statistical bias. For problems presented in a paranormal context a framing effect occurred. Whilst UnExp correlated positively with conjunction proneness (controlling for perception of randomness), there was no association between UnExp and perception of randomness (controlling for conjunction).

This study assessed the extent to which within-individual variation in schizotypy and paranormal belief influenced performance on probabilistic reasoning tasks. A convenience sample of 725 non-clinical adults completed measures assessing schizotypy (Oxford-Liverpool Inventory of Feelings and Experiences; O-Life brief), belief in the paranormal (Revised Paranormal Belief Scale; RPBS) and probabilistic reasoning (perception of randomness, conjunction fallacy, paranormal perception of randomness, and paranormal conjunction fallacy). Latent profile analysis (LPA) identified four distinct groups: class 1, low schizotypy and low paranormal belief (43.9% (...) of sample); class 2, moderate schizotypy and moderate paranormal belief (18.2%); class 3, moderate schizotypy (high cognitive disorganization) and low paranormal belief (29%); and class 4, moderate schizotypy and high paranormal belief (8.9%). Identification of homogeneous classes provided a nuanced understanding of the relative contribution of schizotypy and paranormal belief to differences in probabilistic reasoning performance. Multivariate analysis of covariance revealed that groups with lower levels of paranormal belief (classes 1 and 3) performed significantly better on perception of randomness, but not conjunction problems. Schizotypy had only a negligible effect on performance. Further analysis indicated that framing perception of randomness and conjunction problems in a paranormal context facilitated performance for all groups but class 4. (shrink)

When developing computational models to analyze the tradeoffs between climate risk management strategies (i.e., mitigation, adaptation, or geoengineering), scientists make explicit and implicit decisions that are influenced by their beliefs, values and preferences. Model descriptions typically include only the explicit decisions and are silent on value judgments that may explain these decisions. Eliciting scientists’ mental models, a systematic approach to determining how they think about climate risk management, can help to gain a clearer understanding of their modeling decisions. In order (...) to identify and represent the role of values, beliefs and preferences on decisions, we used an augmented mental models research approach, namely values-informed mental models (ViMM). We conducted and qualitatively analyzed interviews with eleven climate risk management scientists. Our results suggest that these scientists use a similar decision framework to each other to think about modeling climate risk management tradeoffs, including eight specific decisions ranging from defining the model objectives to evaluating the model’s results. The influence of values on these decisions varied between our scientists and between the specific decisions. For instance, scientists invoked ethical values (e.g., concerns about human welfare) when defining objectives, but epistemic values (e.g., concerns about model consistency) were more influential when evaluating model results. ViMM can (i) enable insights that can inform the design of new computational models and (ii) make value judgments explicit and more inclusive of relevant values. This transparency can help model users to better discern the relevance of model results to their own decision framing and concerns. (shrink)

This paper focuses on the most common state policy responses to the opioid crisis, dividing them into six broad categories. Within each category we highlight the rationale behind the group of policies within it, discuss the details and support for individual policies, and explore the research base behind them. The objective is to better understand the most prevalent state responses to the opioid crisis.

Most behavioral decision research takes place in carefully controlled laboratory settings, and examination of relationships between performance and specific real-world decision outcomes is rare. One prior study shows that people who perform better on hypothetical decision tasks, assessed using the Adult Decision-Making Competence (A-DMC) measure, also tend to experience better real-world decision outcomes, as reported on the Decision Outcomes Inventory (DOI). The DOI score reflects avoidance of outcomes that could result from poor decisions, ranging from serious (e.g., bankruptcy) to minor (...) (e.g., blisters from sunburn). The present analyses go beyond the initial work, which focused on the overall DOI score, by analyzing the relationships between specific decision outcomes and A-DMC performance. Most outcomes are significantly more likely among people with lower A-DMC scores, even after taking into account two variables expected to produce worse real-world decision outcomes: younger age and lower socio-economic status. We discuss the usefulness of DOI as a measure of successful real-world decision making. (shrink)

The present study assessed the degree to which probabilistic reasoning performance and thinking style influenced perception of risk and self-reported levels of terrorism-related behaviour change. A sample of 263 respondents, recruited via convenience sampling, completed a series of measures comprising probabilistic reasoning tasks (perception of randomness, base rate, probability, and conjunction fallacy), the Reality Testing subscale of the Inventory of Personality Organization (IPO-RT), the Domain-Specific Risk-Taking Scale, and a terrorism-related behaviour change scale. Structural equation modelling examined three progressive models. Firstly, (...) the Independence Model assumed that probabilistic reasoning, perception of risk and reality testing independently predicted terrorism-related behaviour change. Secondly, the Mediation Model supposed that probabilistic reasoning and reality testing correlated, and indirectly predicted terrorism-related behaviour change through perception of risk. Lastly, the Dual-Influence Model proposed that probabilistic reasoning indirectly predicted terrorism-related behaviour change via perception of risk, independent of reality testing. Results indicated that performance on probabilistic reasoning tasks most strongly predicted perception of risk, and preference for an intuitive thinking style (measured by the IPO-RT) best explained terrorism-related behaviour change. The combination of perception of risk with probabilistic reasoning ability in the Dual-Influence Model enhanced the predictive power of the analytical-rational route, with conjunction fallacy having a significant indirect effect on terrorism-related behaviour change via perception of risk. The Dual-Influence Model possessed superior fit and reported similar predictive relations between intuitive-experiential and analytical-rational routes and terrorism-related behaviour change. The discussion critically examines these findings in relation to dual-processing frameworks. This includes considering the limitations of current operationalisations and recommendations for future research that align outcomes and subsequent work more closely to specific dual-process models.

Schopenhauer’s pessimistic philosophy is a depressing read. He writes many pages about how suffering is the norm, and any happiness we feel is merely a temporary alleviation of suffering. Even so, his account of suffering rings true to many readers. What are we to do with our lives if Schopenhauer is right, and we are doomed to suffer? In this paper, I use William James’ pragmatic method to find practical implications of Schopenhauer’s pessimism. I provide a model for how we (...) are to live our lives in a suffering world, a model that provides means to reduce suffering. (shrink)

Competing arguments surrounding the relationships between inequalities and labor rights have persisted over time. This paper explores whether labor rights increase or decrease two types of wage inequalities: vertical inequality and horizontal inequality. Vertical inequalities reflect inequalities in wealth or income between individuals, while horizontal inequalities reflect inequalities between social, ethnic, economic, and political groups which are usually culturally defined or socially constructed. By broadening the scope beyond traditional indicators of inequality (i.e., vertical inequality) to include horizontal inequality, we test (...) whether government respect for labor rights can help reduce inequality. We find that as labor rights and practices improve, countries see a decrease in horizontal inequality. Furthermore, as stronger protections for labor rights improve within countries, this also serves to reduce individual levels of inequality (i.e., vertical inequality). (shrink)

Decision-making competence reflects individual differences in the susceptibility to decision-making errors, measured using tasks common from behavioral decision research (e.g., framing effects, under/overconfidence, following decision rules). Prior research demonstrates that those with higher decision-making competence report lower incidence of health-risking and antisocial behaviors, but there has been less focus on intermediate mechanisms that may impact real-world decisions, and, in particular, those implicated by normative models. Here we test the associations between measures of youth decision-making competence (Y-DMC) and one such mechanism, (...) the degree to which individuals make choices consistent with maximizing expected value (EV). Using a task involving hypothetical gambles, we find that greater EV sensitivity is associated with greater Y-DMC. Higher Y-DMC scores are associated with (a) choosing risky options when expected value favors those options and (b) avoiding risky options when expected value favors a certain option. This relationship is stronger for gambles that involved potential losses. The results suggest that Y-DMC captures decision processes consistent with standard normative evaluations of risky decisions.

Background. To inform their health decisions, patients may seek narratives describing other patients' evaluations of their treatment experiences. Narratives can provide anti-treatment or pro-treatment evaluative meaning that low-numerate patients may especially struggle to derive from statistical information. Here, we examined whether anti-vaccine narratives had relatively stronger effects on the perceived informativeness and judged vaccination probabilities reported among recipients with lower numeracy. Methods. Participants from a nationally representative US internet panel were randomly assigned to an anti-vaccine or pro-vaccine narrative, as presented (...) by a patient discussing a personal experience, a physician discussing a patient's experience, or a physician discussing the experiences of 50 patients. Anti-vaccine narratives described flu experiences of patients who got the flu after getting vaccinated; pro-vaccine narratives described flu experiences of patients who got the flu after not getting vaccinated. Participants indicated their probability of getting vaccinated and rated the informativeness of the narratives. Results. Participants with lower numeracy generally perceived narratives as more informative. By comparison, participants with higher numeracy rated especially anti-vaccine narratives as less informative. Anti-vaccine narratives reduced the judged vaccination probabilities as compared with pro-vaccine narratives, especially among participants with lower numeracy. Mediation analyses suggested that low-numerate individuals' vaccination probabilities were reduced by anti-vaccine narratives - and, to a lesser extent, boosted by pro-vaccine narratives - because they perceived narratives to be more informative. These findings were similar for narratives provided by patients and physicians. Conclusions. Patients with lower numeracy may rely more on narrative information when making their decisions. These findings have implications for the development of health communications and decision AIDS. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Diacritics 29.4 (1999) 40-57 [Access article in PDF] Bogeyman: Benedict Anderson's "Derivative" Discourse Andrew Parker Between life and death, nationalism has as its own proper space the experience of haunting. There is no nationalism without some ghost. -Jacques Derrida, "Onto-Theology of National-Humanism" Writing a mere decade ago about Benedict Anderson's Imagined Communities, Timothy Brennan noted that "with the exception of some recent sociological works which use literary theories, it (...) is rare in English to see 'nation-ness' talked about as an imaginative vision--as a topic worthy of full fictional realization.... Even in the underrepresented branch of Third World English studies, one is likely to find discussions of race and colonialism, but not the 'nation' as such" [47]. If these sentences appear astonishing today--if over the past ten years we seem to have done little else but regard the nation as an imaginative construction--our sense of surprise may help to register how rapidly and profoundly Anderson's work has transformed the nature of literary and cultural studies. Viewing the modern nation primarily as an anthropological rather than political category, one that has less inherently to do with ideologies than with kinship, gender, and religion, Anderson argues in Imagined Communities for the irreducibility of material-cultural practices (what he memorably termed "print-capitalism") in creating and sustaining the "imagined community" of a nation whose citizens maintain "deep attachments" to each other in the absence of face-to-face contact: "the members of even the smallest nation will never know most of their fellow-members, meet them, or even hear of them, yet in the minds of each lives the image of their communion" [6]. Part of what makes such communities national, Anderson suggests, is a shared experience of simultaneity modeled on the spatio-temporal organization of newspapers and novels, for "these forms provided the technical means for 're-presenting' the kind of imagined community that is the nation" by furnishing their reader-consumers with a "complex gloss on the word 'meanwhile'" [25]. The "old-fashioned novel" especially, through its distinctive structures of address and omniscient point of view, becomes in this schema a "device" for generating a sociologically complex world populated by characters who, even though they "may be largely unaware of each other," nevertheless move together "calendrically through homogeneous, empty time"--a world, in short, that may be considered "a precise analogue of the idea of the nation, which also is conceived as a solid community moving steadily up (or down) history" [25-26]. As Jonathan Culler aptly summarizes in his contribution to this issue, Anderson thus takes the novel to be "a precondition for the nation" [24], "a formal condition of imagining the nation--a structural condition of possibility" [37]. Such strong emphasis on the novel as "a force for imagining the communities that are nations" certainly helps to explain why Imagined Communities so swiftly and pervasively became doxa in literary study--even if, as Culler elaborates, some of Anderson's readers have mistaken his argument for a stronger if less defensible [End Page 40] version that sees the novel as "a force in shaping or legitimating the nation" [37].While Anderson's analogy between novel and nation has been put by literary critics to a multitude of creative uses, what has been acknowledged much less commonly is that his literary interests are by no means exhausted by the paradigm for which he is best known. 1 The very title of his most recent book is, significantly as we shall see, a translated quotation from a novel, and he returns repeatedly for insights into the politics of literary form not only to Walter Benjamin but to certain exemplary "nationalist" novelists, José Rizal and Pramoedya Ananta Toer first and foremost. Where The Spectre of Comparisons is unusual in containing chapter-length readings of literary works (several of them reprinted from the earlier Language and Power), Imagined Communities was no stranger to detailed discussions of fiction. We may be struck, in fact, by the extent to which Anderson's theoretical and historical studies locate themselves persistently over time with reference to "literature... (shrink)

Three comments are made. The proposal that recollection and familiarity-based recognition take different thalamic routes does not fit recent experimental evidence, suggesting that mediodorsal thalamus acts in an integrative role with respect to prefrontal cortex. Second, the role of frontal cortex in episodic memory has been understated. Third, the role of the hippocampal axis is likely to be the computation and storage of ideothetic information.

Study of “theory of mind” in nonhuman primates is hampered both by the lack of rigorous methodology that Heyes stresses and by our lack of knowledge of the cognitive neuroscience of nonhuman primate conceptual structure. Recent advances in this field indicate that progress can be made by first asking simpler research questions.

Rolls's proposal that the amygdala is critical for the association of visual objects with reward is not consistent with recent ablation evidence. Stimulus-reward association learning is more likely to depend on basal forebrain efferents to the inferior temporal cortex, some of which pass through the amygdala. It is more likely that the amygdala is involved in rapid modulation of stimulus reward value.

Although the question 'Does psi exist?' has become a recurrent and intransigent problem for psychological science, seen from a historical and social context, there appear to be reasons as to why no determined effort has been made to resolve the question. The sporadic exchanges from parapsychologists and critics appear only to reinforce the status quo: At most, it is agreed that some form of 'anomaly' has been established but there is no consensus about its nature. Yet such a defeatist stance (...) shies away from the long tradition of research into spontaneous phenomena, as well as experimental research with dreams and hypnosis, all of which suggests that, if psi is real, it is not just an anomaly but has true information content and dynamic effects. This work is briefly reviewed and then, since much of the current controversy has centred on the ganzfeld technique, this is used as an example of the issues involved. The ganzfeld induces sleep-onset imagery during which randomly selected film clips are viewed by a sender as a source of psi-mediated information to be incorporated into the imagery. Our current development of the ganzfeld technique, known as the digital autoganzfeld, takes the work beyond 'anomaly status' since it enables real-time recordings to be made of apparently high-quality psi as it enters consciousness. Initial findings from this illustrate the complexity of the phenomena and the need for more adventurous designs in order to stimulate theory development. There is no doubt that technology now exists which would enable us to resolve the issues raised. Whether the area turns out to be a mixture of rampant fraud, artefact and subjective validation or to present genuine phenomena, a resolution of the issue may be seen as having unwanted implications for psychology -- which may be one of the factors explaining why the controversy is left to continue as it is, unresolved. New questions are needed which take into account the natural context in which psi appears to occur, along with the support needed to reach clear answers. (shrink)
