BACKGROUND: Reasoning biases have been suggested as risk factors for delusional ideation in both patients and non-clinical individuals. Still, it is unclear how these biases are longitudinally related to delusions in the general population. We hence aimed to investigate longitudinal associations between reasoning biases and delusional ideation in the general population. METHODS: We conducted an online cohort study with 1184 adults from the German and Swiss general population. Participants completed measures on reasoning biases (jumping-to-conclusion bias JTC, liberal acceptance bias LA, (...) bias against disconfirmatory evidence BADE, possibility of being mistaken PM) and delusional ideation at baseline, and delusional ideation 7 to 8 months later. RESULTS: A greater JTC bias was associated with a greater increase in delusional ideation over the following months. This association was better described by a positive quadratic relationship. Neither BADE, LA nor PM were associated with subsequent changes in delusional ideation. CONCLUSIONS: This study suggests that jumping-to-conclusions predicts delusional ideation in the general population but that this association may follow a quadratic trajectory. While no other associations turned significant, future studies with shorter temporal distances may shed further light on the role of reasoning biases as risk factors for delusional ideation in non-clinical samples.

An overview and assessment of the current state of research on individual consumption of Fair Trade (FT) products is given on the basis of 51 journal publications. Arranging this field of ethical consumption research according to key research objectives, theoretical approaches, methods, and study population, the review suggests that most studies apply social psychological approaches focusing mainly on consumer attitudes. Fewer studies draw on economic approaches focusing on consumers’ willingness to pay ethical premia for FT products or sociological approaches relying (...) on the concept of consumer identity. Experimental, qualitative and conventional survey methods are used approximately equally often. Almost all studies draw on convenience or purposive samples and most studies are conducted in the USA or the United Kingdom. Several problems in current research are identified: amongst others, studies’ rather narrow theoretical focus, potential hypothetical and social desirability bias of conventional survey data, and a lack of generalizability of empirical findings. In turn, we suggest that research would benefit from both a multiple-motives and a multiple-methods perspective. Considering competing theories can help to single out key behavioral determinants of individual FT consumption. The combination of different methods such as conventional surveys and field experiments contributes to uncovering respondents’ truthful answers and improves generalizability of results. Scholars in the field of ethical consumption research should use experiments to detect causal relations proposed by theories and conduct cross-country surveys to gather insights as to how differences in market structures, cultural traits, and other path dependencies affect patterns of individual FT consumption.

How (Not) to Be Secular is what Jamie Smith calls "your hitchhiker's guide to the present" -- it is both a reading guide to Charles Taylor's monumental work A Secular Age and philosophical guidance on how we might learn to live in our times. Taylor's landmark book A Secular Age (2007) provides a monumental, incisive analysis of what it means to live in the post-Christian present -- a pluralist world of competing beliefs and growing unbelief. Jamie Smith's book is a (...) compact field guide to Taylor's insightful study of the secular, making that very significant but daunting work accessible to a wide array of readers. Even more, though, Smith's How (Not) to Be Secular is a practical philosophical guidebook, a kind of how-to manual on how to live in our secular age. It ultimately offers us an adventure in self-understanding and maps out a way to get our bearings in today's secular culture, no matter who "we" are -- whether believers or skeptics, devout or doubting, self-assured or puzzled and confused. This is a book for any thinking person to chew on. (shrink)

We provide self-contained proof of a theorem relating probabilistic coherence of forecasts to their non-domination by rival forecasts with respect to any proper scoring rule. The theorem recapitulates insights achieved by other investigators, and clarifi es the connection of coherence and proper scoring rules to Bregman divergence.

Inspite of growing interest in research on language universals the concept of language universal itself has not been clarified beyond its status in Greenberg 1966. The present paper is an attempt at further clarification. The concept of language universal presents at least the following basic problems : Which entities are to be called universal? How can universality statements be deductively related to statements on individual languages and to non-linguistic statements, e.g. psychological ones? How are we to conceive the relation between (...) the 'empirical' and the 'non-empirical' in universality research? It is argued that the universal entities should be properties of languages. Three conceptions of universals are characterized: The Naive View , the Semantic View , and the Pragmatic View proposed by the author . It is argued that the Naive View and the Semantic View do not, and that the Pragmatic View may solve the basic problems formulated in Part I. Combining the Pragmatic View with the conception of theories developed in Lieb to appear the author characterizes the ultimate aim of universality research as defining a set of properties that, if taken as universal by any linguist, maximize the fruitfulness of any theory of language. The main task of universality research consists in making universality proposals that are well-founded with respect to that aim. Various principles are suggested by which the well-foundedness of universality proposals can be judged. (shrink)

Many enzymes are inhibited by their own substrates, leading to velocity curves that rise to a maximum and then descend as the substrate concentration increases. Substrate inhibition is often regarded as a biochemical oddity and experimental annoyance. We show, using several case studies, that substrate inhibition often has important biological functions. In each case we discuss, the biological significance is different. Substrate inhibition of tyrosine hydroxylase results in a steady synthesis of dopamine despite large fluctuations in tyrosine due to meals. (...) Substrate inhibition of acetylcholinesterase enhances the neural signal and allows rapid signal termination. Substrate inhibition of phosphofructokinase ensures that resources are not devoted to manufacturing ATP when it is plentiful. In folate metabolism, substrate inhibition maintains reactions rates in the face of substantial folate deprivation. Substrate inhibition of DNA methyltransferase serves to faithfully copy DNA methylation patterns when cells divide while preventing de novo methylation of methyl‐free promoter regions. (shrink)

Practical deliberation often involves conditional judgements about what will (likely) happen if certain alternatives are pursued. It is widely assumed that the conditionals useful in deliberation are counterfactual or subjunctive conditionals. Against this, I argue that the conditionals of deliberation are indicatives. Key to the argument is an account of the relation between 'straightforward' future-directed conditionals like ' If the house is not painted, it will soon look quite shabby' and * "w e r e ' ' e d F (...) D C s like ' If the house were not to be painted, it would soon look quite shabby': an account on which both of these types of FDCs are grouped with the indicatives for semantic treatment and on which, while conditionals of both types are properly used in means/ends deliberations, those of the ' were'ed-up variety are especially well suited for that purpose.

A variety of theoretical approaches have been taken in an attempt to understand, explain, and promote pro-environmental behavior. The present article gives an overview, including specific applications, and identifies and discusses various strategies used by researchers to deal with the availability of different approaches. The overview includes elementary rational choice theory, the theory of planned behavior, norm-activation theory, theories of habitual behavior, and theories within a social dilemma framework. Strategies identified are ‘extending existing theories by single explanatory factors’, ‘comparing theories’ (...) in a competitive manner, and ‘combining theories’ in an integrative manner. It is argued that research would benefit from more standardization in empirical applications, from more competitive theory testing as opposed to integrative theory testing, and from an evaluation of approaches on theoretical grounds as opposed to focusing solely on empirical performance.

I AM GRATEFUL to Dean Dougherty and his colleagues for inviting me to this celebration of Paul Weiss's birthday. I admire and care for Paul Weiss, and I have learned from him. I have also learned because of him. Even now, years after my graduate studies, he is a familiar, a benign, but of course not always a gentle goad to my thoughts. Just the other day--I suppose Paul thought I was becoming too comfortable--he added a postscript to a short (...) note, urging me to hurry up to become seventy, because seventy is so fine a time to philosophize.

The great charge against ontologies, according to Bergmann, is that they are senseless: they are paradoxical or absurd because they deny what is surely true or claim to say what can't be told. The answer to this charge, or Bergmann's answer, is that it con fuses appearance and reality. Ontological claims seem to us senseless when we fail to see that one or several of the words in them is used philosophically. To have their sense be clear, we have only (...) to talk commonsensically about the philosophical words, to set out and understand their patterns, and then to see how the patterns interlock to account for what there is.

Fully adequate answers to these questions are best provided in a comprehensive philosophy of logic. Within shorter compass, it is nevertheless possible to be guided by some conditions that are necessary to adequate answers. These will be results of the analysis of propositions and statements. They are necessary, since no answers to the questions about the constants will be acceptable if, for example, it follows from the answers that propositions or statements cannot be unities, or that propositions or statements cannot (...) be true or false.
