This article probes the practical ethical implications of AI system design by reconsidering the important topic of bias in the datasets used to train autonomous intelligent systems. The discussion draws on recent work concerning behaviour-guiding technologies, and it adopts a cautious form of technological utopianism by assuming it is potentially beneficial for society at large if AI systems are designed to be comparatively free from the biases that characterise human behaviour. However, the argument presented here critiques the common well-intentioned requirement (...) that, in order to achieve this, all such datasets must be debiased prior to training. By focusing specifically on gender-bias in Neural Machine Translation systems, three automated strategies for the removal of bias are considered – downsampling, upsampling, and counterfactual augmentation – and it is shown that systems trained on datasets debiased using these approaches all achieve general translation performance that is much worse than a baseline system. In addition, most of them also achieve worse performance in relation to metrics that quantify the degree of gender bias in the system outputs. By contrast, it is shown that the technique of domain adaptation can be effectively deployed to debias existing NMT systems after they have been fully trained. This enables them to produce translations that are quantitatively far less biased when analysed using gender-based metrics, but which also achieve state-of-the-art general performance. It is hoped that the discussion presented here will reinvigorate ongoing debates about how and why bias can be most effectively reduced in state-of-the-art AI systems. (shrink)

Evidence of a causal role for genes in human behavior underpins genetic essentialism, the scientifically flawed and socially hazardous idea that heritable characteristics are immutable. Behavior geneticists can challenge this idea by designing research that brings the contextual dependence of heritability estimates into sharper focus, and by incorporating a relevant statement into research reports and public outreach.

Because Paul could never address any problem without relating it to theology, Romans will never lack interpreters or debate. In this essay, the so-called “New Perspective on Paul,” which has sparked much recent discussion, is measured against the theology of Paul's central letter.

A review of Leonardo Polo’s thought about human evolution in light of the last three decades of palaeontological and archaeological findings and developments. The understanding of human evolution as the essentialisation of the human body allows for the integration of those discoveries and developments in his Transcendental Anthropology.

Drawing on accounts from interviews with white women, this article explores the production of narratives of the self. It suggests that the story produced of the self is not inevitable and may revolve around notions of sameness and difference that, in turn, depend on the positionality of individuals in terms of normative discourses of `race', class and gender. Sally can be seen to be reciting the process of subjection in the way she creates herself as the subject of a narrative, (...) using tropes of difference and sameness to explain who she is and who she is not. However, for the others, the norms and conventions of lifestory do not conform with their experiences of subjection. This is because, in the case of Madeleine, she does not experience an easily retold sense of herself, while Deborah appears to want to present herself as so inevitable and conforming to dominant norms that there is no story to tell.
