In contrast to the opinion of numerous authors (e.g. R. Rudner, P. Kitcher, L. R. Graham, M. Dummett, N. Chomsky, R. Lewontin, etc.) it is argued here that the formation of opinion in science should be greatly insulated from political considerations. Special attention is devoted to the view that methodological standards for evaluation of scientific theories ought to vary according to the envisaged political uses of these theories.I wish to thank the Alexander von Humboldt Foundation for having supported the work on this paper. 相似文献

This two-part article examines the competition between the clonal selection theory and the instructive theory of the immune response from 1957–1967. In Part I the concept of a temporally extended theory is introduced, which requires attention to the hitherto largely ignored issue of theory individuation. Factors which influence the acceptability of such an extended theory at different temporal points are also embedded in a Bayesian framework, which is shown to provide a rational account of belief change in science. In Part II these factors, as elaborated in the Bayesian framework, are applied to the case of the success of the clonal selection theory and the failure of the instructive theory. 相似文献

African Americans are at significantly greater risk of hypertension and worse cardiovascular outcomes than other racialized groups, yet hypertension intervention effects remain limited. Thus, it is necessary to understand the potential mechanisms whereby interventions may be more effectively targeted to improve health. Supported by prior research evidence and guided by the Biobehavioral Family Model, this study examined associations between family relationship quality, psychological wellbeing, and self-management behaviors for African Americans with hypertension. Data were pooled from three Midlife Development in the U.S. projects, resulting in a sample of 317 African Americans (63.4% female, Mage = 53.32) with self-reported high blood pressure in the past 12 months. We tested four cross-sectional multiple mediator models, with depressed mood and environmental mastery mediating associations between family strain and exercise, smoking, problematic alcohol use, and stress-eating. Environmental mastery mediated the association between greater family strain and decreased odds of achieving recommended exercise levels; greater odds of reporting problematic alcohol use; and greater stress-eating. Though family strain was associated with depressed mood in each model, this variable did not serve as an indirect pathway to self-management behaviors. Family strain, and the potential pathway identified via environmental mastery, may be a meaningful predictor of disease self-management for African Americans with hypertension. Longitudinal studies are needed to examine directionality and to support intervention trials for improving self-management and hypertension outcomes. 相似文献

IntroductionImplicit theories of intelligence are beliefs that people form regarding the malleability of intelligence. The so-called “growth” and “fixed” mindsets respectively view intelligence as a characteristic that can or cannot be changed. Psychology, as a science, also offers diverging responses. The developmental and differential traditions in the study of intelligence merely provide different answers because they do not focus on the same sources of variability nor on the same dimensions of intelligence.ObjectivesThe research question that guided the present studies was: Are people's naïve theories influenced by the same factors that drive developmental and differential psychologists to different conclusions?MethodIn Study 1, we first assessed participants’ (n = 509) reference norm orientation (i.e. whether they tend to focus on individual or social comparison), using a task in which they had to predict the school results of an hypothetical child. Then we administered a French version of Dweck's (2007) mindset scale. In study 2, we first asked participants (n = 530) to choose between two definitions of intelligence focusing either on its fluid or crystalized dimensions. Then we administered the French Mindset Scale and asked participants to justify their conclusion.ResultsBoth variables of interest (reference norm orientation and preferred definition of intelligence) had a significant effect on the participant's incremental beliefs.ConclusionThe results of the two studies as well as the qualitative analysis of participants’ arguments suggest that mindsets, like scientific theories, partly stem from the fact that the same question regarding intelligence malleability can be approached with two different perspectives. 相似文献

The present research aims to identify unique characteristics of written conspiracy theories. In two pre-registered quantitative human-coded content analyses, we compared 36 pairs of conspiratorial and non-conspiratorial online articles about various events. As predicted, conspiratorial articles—compared to non-conspiratorial articles—contained less factual, more emotional and more threat-related information. Also, we predicted and found that conspiratorial articles presented more argumentation against the opposing standpoint and that they provided explanations that were more dispositional and less falsifiable. Contrary to our predictions, we did not consistently observe that conspiratorial articles presented less argumentation for their own standpoint. Also, we did not find consistent support that conspiratorial articles provided less information about the specific process or more information about the underlying goals of the respective events, or that conspiratorial explanations attributed the events to a lesser extent to situational factors. We discuss the relevance of our findings for the understanding of conspiracy theories. 相似文献

Stewart Clem 《The Journal of religious ethics》2023,51(1):11-31
In this essay, I argue that Christian ethicists should not think of themselves as religious ethicists. I defend this claim by arguing that the concept of religious ethics, as it has come to be understood as a discipline that is distinct from secular ethics, is incoherent. In part one, I describe the fraught attempts by theologians in the 20th century to identify the distinctiveness of Christian ethics. In part two, I argue that certain accounts of natural law unwittingly reinforce a problematic conception of secular ethics. Part three examines some trends in religious studies and comparative religious ethics to highlight problematic conceptions of religion. Drawing together these strands of inquiry, I contend that that the secular-religious dichotomy in contemporary ethics should be rejected, but by the same token, I suggest that comparative ethics remains a worthwhile enterprise. 相似文献

This study used an American sample collected over a period of approximately 2 decades (at 3 time points) to examine the temporal relationships between psychological well-being and personality traits (i.e., neuroticism, extraversion, agreeableness, conscientiousness, and openness to experience). The random-intercept cross-lagged panel model was used to separate between-person and within-person sources of variation. Between-person correlations were comparable to those of previous studies. New insights were gained at the within-person level. There were reciprocal relationships between psychological well-being and openness and extraversion, suggesting the joint development of plasticity-related traits and well-being over time. The relationships between psychological well-being and conscientiousness and agreeableness were unidirectional, with psychological well-being preceding these traits. Despite a strong between-person association between neuroticism and psychological well-being, the two were not related at the within-person level. 相似文献

When people face difficult life events, such as cancer or bereavement, they fare better when they receive support. These “experiencers” are likely to seek and receive support from a wide range of people, from close others to acquaintances. Indeed, the social support literature has long acknowledged the value of having a diverse support network. Research suggests that experiencers often perceive “weak ties” (i.e., acquaintances) as sources of support, and that experiencers sometimes prefer to get support from weak ties rather than strong ties. Providing support can be challenging for all kinds of supporters, however weak ties may be more likely than strong ties to allow worries about their inability to provide effective support to stop them from providing any support at all, thus depriving experiencers of opportunities for additional support. In this paper, we focus on the fact that often the provision of support occurs via a social interaction. We draw on the social psychology literature on minimal social interactions to suggest reasons why potential weak tie supporters might doubt their ability to provide effective support, and to generate advice to encourage potential supporters to reach out. Finally, we suggest future areas of research, with the ultimate goal of helping to expand the support that is available for people experiencing difficult life events. 相似文献
