Verwijzend naar de Burndy Library conferentie in 1973 schrijft P.A. Kroes in de inleiding tot de ‘proceedings’ van de internationale conferentie over ‘Technische ontwikkeling en natuurwetenschap in de 19e en 20e eeuw’,1 dat tijdens de eerstgenoemde conferentie de meeste deelnemers van mening waren dat de opvatting van techniek als toegepaste wetenschap onjuist was. Technische produkten volgen niet zonder meer lineair uit de beschikbare natuurwetenschappelijke kennis. Een dergelijke zienswijze leidt bovendien snel tot de gedachte dat bij een autonome ontwikkeling van de (...) natuurwetenschap, ook de techniek zich autonoom zou ontwikkelen. Echter, Kroes moet concluderen, dat ondanks alle moeite die men zich sindsdien heeft gegeven om de verhouding tussen techniek en natuurwetenschap te bestuderen en nader te bepalen, hierin bijzonder weinig vooruitgang is geboekt.

Evolutionary psychology is put forward by its defenders as an extension of evolutionary biology, bringing psychology within the integrated causal chain of the hard sciences. It is extolled as a new paradigm for integrating psychology with the rest of science. We argue that such claims misrepresent the methods and explanations of evolutionary biology, and present a distorted view of the consequences that might be drawn from evolutionary biology for views of human nature. General theses about adaptation in biology are empty (...) schemata, not laws of nature allowing the subsumption of mind under biology. Functional thinking is an indispensable tool for psychology, mostly of value in abstractive unification and as a heuristic, but it gains little from association with evolutionary notions of selection. Thus, we argue, the cherished integrative causal model evaporates, and evolutionary phraseology serves no more than rhetorical purposes. Moreover, the universality of human nature and the evolutionary irrelevance of individual variation are presented as biological truths that psychologists should respect in their approach to mind. On closer inspection, this turns out to be rather dubious biology. Psychology might conceivably be better off as a continuation of biology by different means, but evolutionary psychology does not provide the conceptual integration leading to such a happy union.

This interview study investigates the short- and long-term implications of incidental findings detected through brain imaging on research participants’ lives and their surroundings. For this study, nine participants of the Rotterdam Scan Study with an incidental finding were approached and interviewed. When examining research participants’ narratives on the impact of the disclosure of incidental findings, the authors identified five sets of tensions with regard to motivations for and expectations of research participation, preferences regarding disclosure, short- and long-term impacts and impacts (...) on self and others. The paper shows: that the impact of incidental findings may be greater than participants at first let on; incidental findings can have significant effects on participants’ social environment; and participants may not feel prepared for disclosure even if incidental findings have been discussed during the informed consent process. The authors call for investigators to be aware of research participants’ experiences and these short- and long-term impacts when designing suitable courses of action for the detection and management of incidental findings in research settings.

Selection on grandparental investment is more complex than Coall & Hertwig (C&H) propose. Patterns of investment are subject to an intergenerational conflict over how resources should be distributed to maximize fitness. Grandparents may be selected to distribute resources unevenly, while their descendants will be selected to manipulate investment in their own favor. Here we outline the evolutionary basis of this conflict.

Kaum einer hat die offene Gesellschaft in der politischen Philosophie des 20. Jahrhunderts so leidenschaftlich verteidigt wie Karl Popper. Sein Demokratieverstandnis ist eng gekoppelt an seine Wissenschaftstheorie und die Kritik an Platon, Hegel, Marx. Als Liberaler und sozialer Reformist wird er parteiubergreifend zum Stichwortgeber bundesdeutscher Politik seit den 70er Jahren. Popper-Rezeptionen finden sich bis in die Staatsrechtslehre (namentlich Peter Haberle) und das Bundesverfassungsgericht hinein. Noch heute lasst sich mit Popper gegen Diktaturen wie uberhaupt gegen Konzepte von "Gemeinschaft" Position beziehen - (...) aber auch gegen einen pseudo-liberalen, gnadenlosen Kapitalismus der "Ich-AGs". Mit Beitragen von Dorothea Frede, Peter Haberle, Herbert Keuth, Hubert Kiesewetter, Martin H. W. Mollers, Jurgen Nordmann, Harald Stelzer, Robert Chr. van Ooyen, Robert Zimmer. (shrink)

Although euthanasia and assisted suicide in people with psychiatric disorders is relatively rare, the increasing incidence of EAS requests has given rise to public and political debate. This study aimed to explore support of the public and physicians for euthanasia and assisted suicide in people with psychiatric disorders and examine factors associated with acceptance and conceivability of performing EAS in these patients. A survey was distributed amongst a random sample of Dutch 2641 citizens and 3000 physicians. Acceptance and conceivability of (...) performing EAS, demographics, health status and professional characteristics were measured. Multivariable logistic regression analyses were performed. Of the general public 53% were of the opinion that people with psychiatric disorders should be eligible for EAS, 15% was opposed to this, and 32% remained neutral. Higher educational level, Dutch ethnicity, and higher urbanization level were associated with higher acceptability of EAS whilst a religious life stance and good health were associated with lower acceptability. The percentage of physicians who considered performing EAS in people with psychiatric disorders conceivable ranged between 20% amongst medical specialists and 47% amongst general practitioners. Having received EAS requests from psychiatric patients before was associated with considering performing EAS conceivable. Being female, religious, medical specialist, or psychiatrist were associated with lower conceivability. The majority of the psychiatrists were of the opinion that it is possible to establish whether a psychiatric patient’s suffering is unbearable and without prospect and whether the request is well-considered. The general public shows more support than opposition as to whether patients suffering from a psychiatric disorder should be eligible for EAS, even though one third of the respondents remained neutral. Physicians’ support depends on their specialization; 39% of psychiatrists considered performing EAS in psychiatric patients conceivable. The relatively low conceivability is possibly explained by psychiatric patients often not meeting the eligibility criteria. (shrink)

Rapid developments in Artificial Intelligence are leading to an increasing human reliance on machine decision making. Even in collaborative efforts with Decision Support Systems, where a human expert is expected to make the final decisions, it can be hard to keep the expert actively involved throughout the decision process. DSSs suggest their own solutions and thus invite passive decision making. To keep humans actively ‘on’ the decision-making loop and counter overreliance on machines, we propose a ‘reflection machine’. This system asks (...) users questions about their decision strategy and thereby prompts them to evaluate their own decisions critically. We discuss what forms RMs can take and present a proof-of-concept implementation of a RM that can produce feedback on users’ decisions in the medical and law domains. We show that the prototype requires very little domain knowledge to create reasonably intelligent critiquing questions. With this prototype, we demonstrate the technical feasibility to develop RMs and hope to pave the way for future research into their effectiveness and value. (shrink)

A theory of the joint measurement of quantum mechanical observables is generalized in order to make it applicable to the measurement of the local observables of field theory. Subsequently, the property of local commutativity, which is usually introduced as a postulate, is derived by means of the theory of measurement from a requirement of mutual nondisturbance, which, for local observables performed at a spacelike distance from each other, is interpreted as a requirement of macrocausality. Alternative attempts at establishing a deductive (...) relationship between relativistic causality and local commutativity are reviewed, but found wanting, either because of the assumption of an unwarranted objectivity of the object system (algebraic approach) or because of the use of a projection postulate (operational approach). Finally, the quantum mechanical nonobjectivity is related to certain features of nonlocality which are present in the formalism of quantum mechanics. (shrink)

Colour has been shown to facilitate the recognition of scene images, but only when these images contain natural scenes, for which colour is ‘diagnostic’. Here we investigate whether colour can also facilitate memory for scene images, and whether this would hold for natural scenes in particular. In the first experiment participants first studied a set of colour and greyscale natural and man-made scene images. Next, the same images were presented, randomly mixed with a different set. Participants were asked to indicate (...) whether they had seen the images during the study phase. Surprisingly, performance was better for greyscale than for coloured images, and this difference is due to the higher false alarm rate for both natural and man-made coloured scenes. We hypothesized that this increase in false alarm rate was due to a shift from scrutinizing details of the image to recognition of the gist of the image. A second experiment, utilizing images without a nameable gist, confirmed this hypothesis as participants now performed equally on greyscale and coloured images. In the final experiment we specifically targeted the more detail-based perception and recognition for greyscale images versus the more gist-based perception and recognition for coloured images with a change detection paradigm. The results show that changes to images are detected faster when image-pairs were presented in greyscale than in colour. This counterintuitive result held for both natural and man-made scenes and thus corroborates the shift from more detailed processing of images in greyscale to more gist-based processing of coloured images.
