Current Perspectives in Philosophy of Biology.

This paper examines how the new field of neuroethics is responding to the old problem of difference, particularly to those ideas of biological difference emerging from neuroimaging research that purports to further delineate our understanding of sex and/or gender differences in the brain. As the field develops, it is important to ask what is new about neuroethics compared to bioethics in this regard, and whether the concept of difference is being problematized within broader contexts of power and representation. As a (...) feminist science studies scholar trained in the neurosciences, it seems logical to me that, as a growing field, neuroethics should reach out to the rich bodies of scholarship on the history of medicine, feminist theory and feminist bioethics while attempting to approach discussions of sex, gender and sexuality differences in the brain. What is also clear to me is that feminist scholars need to learn how to engage with neuroimaging studies on sex, gender and sexuality not just to critique, but also to productively contribute to neuroscientific research. The field of neuroethics can potentially provide the appropriate forum for this interdisciplinary engagement and create opportunities for shared perplexity. I suggest three possible points of departure for creating this shared perplexity, namely (i) is difference being measured in the study for the purpose of understanding difference in and of itself, or for the purpose of division?; (ii) is there an appreciation for biological complexity?; and (iii) is it assumed that structural differences can be conveniently translated into functional differences?

En el presente escrito se propone revisar los supuestos que guían la práctica neurocientífica al afirmar diferencias sexuales en el cerebro. Tras la constatación de que una gran parte de la investigación y publicación de hallazgos neurocientíficos dan por hecho tal diferencia, encontramos una gran carga de lo que se ha denominado neurosexismo. Como forma de superarlo y desde la teoría feminista y el compromiso político se propone un acercamiento crítico a las neurociencias, que a modo de colaboración reflexiva entre (...) las disciplinas, pueda constituir un marco de superación de los prejuicios a la hora de hacer, pensar y diseñar la ciencia.

The current neurosciences contribute to the construction of gender/sex to a high degree. Moreover, the subject of gender/sex differences in cognitive abilities attracts an immense public interest. At the same time, the entanglement of gender and science has been shown in many theoretical and empirical analyses. Although the body of literature is very extensive and differentiated with regards to the dimensions of ‘neuroscience of gender’ and ‘gender in neuroscience’, the feeding back of these findings into the field of neuroscience remains (...) a desideratum. Especially, the question of how gender knowledge, i.e. insights from feminist theory on gender/sex and from gender and science studies on knowledge production, may be integrated and applied within the neurosciences has been strongly neglected. Presumably due to their epistemic culture and epistemological presuppositions, these critical engagements are conceived as externalist by critical scholars and neuroscientists alike. In this context, the question arises of how substantiated gender knowledge may be accounted for in neuroscientific research practice? The article outlines methodological considerations for a critical research agenda in the cognitive neurosciences. I present thoughts on how insights and expertise from gender and science studies can be taken into account in the neuroscientific practice of knowledge production. Starting from the assumption that changes in neuroscientific research practices are possible, my aim is to point out possibilities of integrating gender knowledge into the neurosciences. (shrink)

Evidence has long suggested that ‘hardwiring’ is a poor metaphor for brain development. But the metaphor may be an apt one for the dominant paradigm for researching sex differences, which pushes most neuroscience studies of sex/gender inexorably towards the ‘discovery’ of sex/gender differences, and makes contemporary gender structures appear natural and inevitable. The argument we forward in this paper is twofold. In the first part of the paper, we address the dominant ‘hardwiring’ paradigm of sex/gender research in contemporary neuroscience, which (...) is built on broad consensus that there are important ‘original’ sex differences in brain structure and function, organized by sex-differentiating prenatal hormone exposures. We explain why this consensus is both unscientific and unethical. In the second part of the paper, we sketch an alternative research program focused not on the origins of sex/gender differences but on variability and plasticity of brain/behavior. We argue that interventional experiments based on this approach will address more tractable questions, and lead to much more satisfactory results than the brain organization paradigm can provide.

As neuroscience has gained an increased ability to enchant the general public, it has become more and more common to appeal to it as an authority on a wide variety of questions about how humans do and should act. This is especially apparent with the question of gender roles. The term ‘neurosexism’ has been coined to describe the phenomenon of using neuroscientific practices and results to promote sexist conclusions; its feminist response is called ‘neurofeminism’. Here, our aim is to survey (...) the phenomena of neurosexism and neurofeminism using a largely philosophical approach, incorporating concepts from the philosophy of mind, the philosophy of science, ethics, and feminist philosophy. First, we delineate how neuroscientific studies purporting to show sex brain differences may be prone to bias at a number of methodological levels – including the choice of categories to be studied, and the choice of tools for data gathering, analysis, and presentation. Then, we show how interpretations of such studies may wrongly assume the notion of ‘hard-wiring’. Furthermore, lack of attention to distinctions within philosophy of mind may result in a mistaken supposition that brain differences lead to mental and/or psychological and/or behavioral ones. It is not difficult to see how these forms of neurosexism, leading to claims of ‘hard-wired’ gender differences that map onto traditional and harmful gender stereotypes, raise ethical questions. We conclude by briefly considering one: are the harms caused by neurosexist studies and their interpretations outweighed by their potential benefits? (shrink)

O objetivo deste trabalho é apresentar as críticas feitas por neurocientistas às pesquisas que buscam diferenças cognitivas entre homens e mulheres presentes no cérebro, principalmente, utilizando o respaldo da neuroimagem. Desde o início dos anos 2000, a preocupação com a utilização da neurociência para justificar estereótipos de gênero e a falta de critério dos responsáveis para diferenciar as expressões “sexo” e “gênero” têm envolvido diversas neurocientistas no debate mais profundo entre natureza e cultura apresentado por essas pesquisas. Além disso, é (...) imperativo pensarmos no impacto desses resultados, considerando que eles fornecem argumentos para os diversos discursos sociais e contribuem muito para o entendimento das habilidades humanas.

The neuroscientific investigation of sex differences has an unsavoury past, in which scientific claims reinforced and legitimated gender roles in ways that were not scientifically justified. Feminist critics have recently argued that the current use of functional neuroimaging technology in sex differences research largely follows that tradition. These charges of ‘neurosexism’ have been countered with arguments that the research being done is informative and valuable and that an over-emphasis on the perils, rather than the promise, of such research threatens to (...) hinder scientific progress. To investigate the validity of these contrasting concerns, recent functional magnetic resonance imaging (fMRI) investigations of sex differences and citation practices were systematically examined. In line with the notion of neurosexism, the research was found to support the influence of false-positive claims of sex differences in the brain, to enable the proliferation of untested, stereotype-consistent functional interpretations, and to pay insufficient attention to the potential plasticity of sex differences in both brain and mind. This, it is argued, creates a literature biased toward the presentation of sex differences in the brain as extensive, functionally significant, and fixed—and therefore implicitly supportive of a gender essentialist perspective. It is suggested that taking feminist criticisms into account would bring about substantial improvement in the quality of the science, as well as a reduction in socially harmful consequences.

In this paper, I will discuss the responsibilities that scientists have for ensuring their work is interpreted correctly. I will argue that there are three good reasons for scientists to work to ensure the appropriate communication of their findings. First, I will argue that scientists have a general obligation to ensure scientific research is communicated properly based on the vulnerability of others to the misrepresentation of their work. Second, I will argue that scientists have a special obligation to do so (...) because of the power we as a society invest in them as specialists and professionals. Finally, I will argue that scientists ought to ensure their work is interpreted correctly based on prudential, self-interested considerations. I will conclude by offering suggestions regarding policy considerations. (shrink)

Discussions in neuroethics to date have ignored an ever-increasing neuroscientific lilterature on sex differences in brains. If, indeed, there are significant differences in the brains of men versus women and in the brains of boys versus girls, the ethical and social implications loom very large. I argue that recent neuroscientific findings on sex-based brain differences have significant implications for theories of morality and for our understandings of the neuroscience of moral cognition and behavior.

Animal models are used in experiments in the behavioural neurosciences that aim to contribute to the prevention and treatment of cognitive and affective disorders in human beings, such as anxiety and depression. Ironically, those animals that are likely to be the best models for psychopathology are also likely to be considered the ones that are most morally problematic to use, if it seems probable that (and if indeed they are initially selected as models because) they have experiences that are similar (...) to human experiences that we have strong reasons to avoid causing, and indeed aim to alleviate (such as pain, anxiety or sadness). In this paper, against the background of contemporary discussions in animal ethics and the philosophy of animal minds, we discuss the views that it is morally permissible to use animals in these kinds of experiments, and that it is better to use less cognitively complex animals (such as zebrafish) than more complex animals (such as dogs). First, we criticise some justifications for the claim that human beings and more complex animals have higher moral status. We argue that contemporary approaches that attribute equal moral status to all beings that are capable of conscious strivings (e.g. avoiding pain and anxiety; aiming to eat and play) are based on more plausible assumptions. Second, we argue that it is problematic to assume that less cognitively complex animals have a lesser sensory and emotional experience than more complex beings across the board. In specific cases, there might be good reasons to assume that more complex beings would be harmed more by a specific physical or environmental intervention, but it might also be that they sometimes are harmed less because of a better ability to cope. Determining whether a specific experiment is justified is therefore a complex issue. Our aim in this chapter is to stimulate further reflection on these common assumptions behind the use of animal models for psychopathologies. In order to be able to draw more definite conclusions, more research will have to be done on the influence of cognitive complexity on the experience of (human and non-human) animals. (shrink)

Feminist scholars have shown that research on sex/gender differences in the brain is often used to support gender stereotypes. Scientists use a variety of methodological and interpretive strategies to make their results consistent with these stereotypes. In this paper, I analyze functional magnetic resonance imaging (fMRI) research that examines differences between women and men in brain activity associated with emotion and show that these researchers go to great lengths to make their results consistent with the view that women are more (...) emotional than men.

In this work we will take up again the contributions of the feminist philosophy of science around androcentrism, with special emphasis on biology and biomedical sciences. We will propose that such contributions can be ordered according to three different senses of androcentrism, and that important tensions appear between these senses. Following the path traced by Longino, contextual critical empiricism, we will defend that the rational reconstruction of theories can help us to specify where patriarchal decision vectors crouch in scientific practice. (...) To this end, we will present an alternative analysis to Longino’s and use it as an input to discuss the idea of type brains in the framework of the neuroendocrinology of behaviour. (shrink)

According to a standard interpretation of the term, ‘gender’ denotes sets of social roles and expectations conventionally associated with the sexual physiology of human beings. Originally introduced in psychology, the term is now widely used in the social sciences and humanities, as well as in the biological sciences. In this article we introduce and discuss the central themes of contemporary philosophical debates on gender. Particular attention is paid to recent feminist arguments concerning the distinction between sex and gender, and to (...) how feminist debates today intersect with neuroscience research on sex-related differences between human brains.
