For more than 20 years, research has proven the beneficial effect of natural frequencies when it comes to solving Bayesian reasoning tasks (Gigerenzer & Hoffrage, 1995). In a recent meta-analysis, McDowell & Jacobs (2017) showed that presenting a task in natural frequency format increases performance rates to 24% compared to only 4% when the same task is presented in probability format. Nevertheless, on average three quarters of participants in their meta-analysis failed to obtain the correct solution for such a task (...) in frequency format. In this paper, we present an empirical study on what participants typically do wrong when confronted with natural frequencies. We found that many of them did not actually use natural frequencies for their calculations, but translated them back into complicated probabilities instead. This switch from the intuitive presentation format to a less intuitive calculation format will be discussed within the framework of psychological theories (e.g., the Einstellung effect). (shrink)

In teaching statistics in secondary schools and at university, two visualizations are primarily used when situations with two dichotomous characteristics are represented: 2×2 tables and tree diagrams. Both visualizations can be depicted either with probabilities or with frequencies. Visualizations with frequencies have been shown to help students significantly more in Bayesian reasoning problems than probability visualizations do. Because tree diagrams or double-trees (which are largely unknown in school) are node-branch-structures, these two visualizations (compared to the 2×2 table) can even simultaneously (...) display probabilities on branches and frequencies inside the nodes. This is a teaching advantage as it allows the frequency concept to be used to better understand probabilities. However, 2×2 tables and (double-) trees have a decisive disadvantage: While joint probabilities (e.g., P(AB)) are represented in 2×2 tables but no conditional probabilities (e.g., P(A|B)), it is exactly the other way around with (double-) trees. Therefore, a visualization that is equally suitable for the representation of joint probabilities and conditional probabilities is desirable. In this article, we present a new visualization—the frequency net—in which all absolute frequencies and all types of probabilities can be depicted. In addition to a detailed theoretical analysis of the frequency net, we report the results of a study with 249 university students that shows that “net diagrams” can improve reasoning without previous instruction to a similar extent as 2×2 tables and double-trees. Regarding questions about conditional probabilities, frequency visualizations (2×2 table, double-tree, or net diagram with natural frequencies) are consistently superior to probability visualizations. The frequency net performs as well as the frequency double-tree. Only the 2×2 table with frequencies—the only visualization that participants were already familiar with —led to higher performance rates. If, on the other hand, a question about a joint probability had to be answered, all implemented visualizations clearly supported participants’ performance, and no uniform format effect becomes visible. Participants reached the highest performance in the versions with probability 2×2 tables and probability net diagrams. Furthermore, after conducting a detailed error analysis, we report interesting error shifts between the two information formats and the different visualizations and give recommendations for teaching probability.

In the present paper we empirically investigate the psychometric properties of some of the most famous statistical and logical cognitive illusions from the “heuristics and biases” research program by Daniel Kahneman and Amos Tversky, who nearly 50 years ago introduced fascinating brain teasers such as the famous Linda problem, the Wason card selection task, and so-called Bayesian reasoning problems (e.g., the mammography task). In the meantime, a great number of articles has been published that empirically examine single cognitive illusions, theoretically (...) explaining people’s faulty thinking, or proposing and experimentally implementing measures to foster insight and to make these problems accessible to the human mind. Yet these problems have thus far usually been empirically analyzed on an individual-item level only (e.g., by experimentally comparing participants’ performance on various versions of one of these problems). In this paper, by contrast, we examine these illusions as a group and look at the ability to solve them as a psychological construct. Based on an sample ofN= 2,643 Luxembourgian school students of age 16–18 we investigate the internal psychometric structure of these illusions (i.e., Are they substantially correlated? Do they form a reflexive or a formative construct?), their connection to related constructs (e.g., Are they distinguishable from intelligence or mathematical competence in a confirmatory factor analysis?), and the question of which of a person’s abilities can predict the correct solution of these brain teasers (by means of a regression analysis).

Die Rassentheorie, die Geschichtsphilosophie, die Ästhetik und die Naturteleologie haben eine Gemeinsamkeit: In all diesen Themengebieten entwickelte Immanuel Kant ein Denken der Zweckmässigkeit. Die Fokussierung auf diesen Strang macht eine Verbindung sichtbar, die von seinen frühen Schriften zu den unterschiedlichen »Rassen« der Menschen hin zur Kritik der Urteilskraft und damit zu seiner Selbstreflexion über die kritische Philosophie reicht. Karin Hostettler arbeitet das mit diesem Denken verbundene Othering und die damit einhergehende Selbstaffirmation heraus und zeigt so die Selbstverortung der kritischen (...) Philosophie in einer kolonialen Episteme auf. (shrink)

Neo-Scholastic metaphysics plays an outstanding role in 17th century philosophy. The beginnings of the modern scientific view of the world originate from precisely the same time. With reference to the anatomist Francis Glisson (ca. 1597-1677), this study investigates the significance of school metaphysics for the inception of a new form of natural philosophy. It shows that Glisson developed a retrospective theory of substance from his identity as a scientist. In so doing, it casts a surprising light on the formative intellectual (...) conditions governing the emergence of the sciences in the modern age. (shrink)

How does science create knowledge? Epistemic cultures, shaped by affinity, necessity, and historical coincidence, determine how we know what we know. In this book, Karin Knorr Cetina compares two of the most important and intriguing epistemic cultures of our day, those in high energy physics and molecular biology. The first ethnographic study to systematically compare two different scientific laboratory cultures, this book sharpens our focus on epistemic cultures as the basis of the knowledge society.

In Conversation with Karen Barad: Doings of Agential Realism is an accessible introduction to Karen Barad's agential realist philosophy. The authors take on a unique approach to involve the readers in in/formal conversations between Karen, postgraduates, and researchers at a research event held in 2017 at Cape Town, South Africa.

Cultural accounts of scientific ideas and practices have increasingly come to be welcomed as a corrective to previous—and still widely held—theories of scientific knowledge and practices as universal. The editors caution, however, against the temptation to overgeneralize the work of culture, and to lapse into a kind of essentialism that flattens the range and variety of scientific work. The book refers to this tendency as culturalism. The contributors to the volume model a new path where historicized and cultural accounts of (...) scientific practice retain their specificity and complexity without falling into the traps of culturalism. They examine, among other issues, the potential of using notions of culture to study behavior in financial markets; the ideology, organization, and practice of earthquake monitoring and prediction during China's Cultural Revolution; the history of quadratic equations in China; and how studying the "glass ceiling" and employment discrimination became accepted in the social sciences. Demonstrating the need to understand the work of culture as a fluid and dynamic process that directly both shapes and is shaped by scientific practice, Cultures without Culturalism makes an important intervention in science studies.

This book traces and explores the evolution of taste from a design perspective: what it is, how it works and what it does. Karin Tehve examines taste primarily through its recursive relationship to media. This ongoing process changes the relationship between designers and the public, and our understanding of the relationship of individuals to their social contexts. Through an analysis of taste, design is understood to be an active constituent of social life, not as autonomous from it. This book (...) reclaims a term long dismissed from interior design and unveils taste's role as a powerful social and political agent within systems of aesthetics, affecting both its producers and consumers. Each chapter discusses a taste concept or definition, analyzes its reciprocal relationship with media, and explores its implications for interior design. Illustrated with 70 images, taste's relationship to media is viewed through a variety of different lenses, including books, photography, magazines, internet, social media and algorithms. Written for students and scholars of interior design and related design fields, this book will be a helpful resource for all those interested in the question of taste, and is an invitation to produce and consume all media critically.

Generality is a key value in scientific discourses and practices. Throughout history, it has received a variety of meanings and of uses. This collection of original essays aims to inquire into this diversity. Through case studies taken from the history of mathematics, physics and the life sciences, the book provides evidence of different ways of understanding the general in various contexts. It aims at showing how individuals have valued generality and how they have worked with specific types of "general" entities, (...) procedures, and arguments. (shrink)

Die Neuausgabe von Franz Brentanos Schriften zur Ethik und Asthetik basiert auf den von ihm zu Lebzeiten veroffentlichten Aufsatzen. Eine systematische Abhandlung zu diesen Gebieten im Sinne eigenstandiger Monographien aus Brentanos Feder existiert leider nicht. Es gibt lediglich Vorlesungsskripte, aus denen ersichtlich wird, wie Brentano Ethik und Asthetik konzipiert und in welchem Zusammenhang sie mit den anderen Teilen seines Werkes, allen voran der Psychologie, stehen. Die hier vorliegenden kurzen Abhandlungen und Vortrage behandeln spezielle Aspekte und Fragen aus dem Bereich der (...) Ethik und der Asthetik und sind auf die jeweilige Leser- bzw. Horerschaft zugeschnitten. Sie konnen allein stehen, konnen aber auch als Exemplifikationen von Brentanos empirisch-analytischer Philosophie betrachtet werden.". (shrink)

Eine Einleitung von Wilhelm Baumgartner eroffnet den Zugang zu den vorliegenden Schriften.".

A wide-ranging history of the intellectual developments that produced the modern idea of the algorithm. Bringing together the histories of mathematics, computer science, and linguistic thought, Language and the Rise of the Algorithm reveals how recent developments in artificial intelligence are reopening an issue that troubled mathematicians long before the computer age. How do you draw the line between computational rules and the complexities of making systems comprehensible to people? Here Jeffrey M. Binder offers a compelling tour of four (...) visions of universal computation that addressed this issue in very different ways: G. W. Leibniz's calculus ratiocinator; a universal algebra scheme Nicolas de Condorcet designed during the French Revolution; George Boole's nineteenth-century logic system; and the early programming language ALGOL, whose name is short for algorithmic language. These episodes show that symbolic computation has repeatedly become entangled in debates about the nature of communication. To what extent can meaning be controlled by individuals, like the values of a and b in algebra, and to what extent is meaning inevitably social? By attending to this long-neglected question, we come to see that the modern idea of the algorithm is implicated in a long history of attempts to maintain a disciplinary boundary separating technical knowledge from the languages people speak day to day. Machine learning, in its increasing dependence on words, now places this boundary in jeopardy, making its stakes all the more urgent to understand. The idea of the algorithm is a levee holding back the social complexity of language, and it is about to break. This book is about the flood that inspired its construction. (shrink)

A CHOICE Outstanding Academic Title 2012! Contemporary picturebooks open up spaces for philosophical dialogues between people of all ages. As works of art, picturebooks offer unique opportunities to explore ideas and to create meaning collaboratively. This book considers censorship of certain well-known picturebooks, challenging the assumptions on which this censorship is based. Through a lively exploration of children's responses to these same picturebooks the authors paint a way of working philosophically based on respectful listening and creative and authentic interactions, rather (...) than scripted lessons. This dialogical process challenges much current practice in education. The authors propose that a courageous and critical practice of listening is central to the facilitation of mutually educative dialogue. This book will be of interest to scholars and students of education studies, philosophy of education, literacy teaching and learning, children's literature, childhood and pedagogy. (shrink)

In feminist media studies, the growing body of research on media production has indicated that journalism remains divided along gender lines. The purpose of this study is to address the lack of relevant multi-method research on gender inequality in journalism. To assess the structural position of women in the journalistic workforce, the authors conducted a large-scale survey of journalists in Belgium. The survey results were explored in more depth by conducting qualitative interviews with 19 female journalists. The analysis confirms the (...) existence of all traditional barriers that women journalists experience. The added value of this study is that it enumerates several additional difficulties, and offers insight into the strategies that the respondents use to deal with gender-related career obstacles. These strategies were associated with the degree of flexibility in the newsroom for journalists with children, the choice to work part-time or freelance, and the use of new communication technologies.
