The Ghost in the Machine has an American accent: value conflict in GPT-3

The alignment problem in the context of large language models must consider the plurality of human values in our world. Whilst there are many resonant and overlapping values amongst the world’s cultures, there are also many conflicting, yet equally valid, values. It is important to observe which cultural values a model exhibits, particularly when there is a value conflict between input prompts and generated outputs. We discuss how the co- creation of language and cultural value impacts large language models (LLMs). We explore the constitution of the training data for GPT-3 and compare that to the world’s language and internet access demographics, as well as to reported statistical profiles of dominant values in some Nation-states. We stress tested GPT-3 with a range of value-rich texts representing several languages and nations; including some with values orthogonal to dominant US public opinion as reported by the World Values Survey. We observed when values embedded in the input text were mutated in the generated outputs and noted when these conflicting values were more aligned with reported dominant US values. Our discussion of these results uses a moral value pluralism (MVP) lens to better understand these value mutations. Finally, we provide recommendations for how our work may contribute to other current work in the field

Normative implications of a strong definition of medical futility = Implicaciones normativas de una definición robusta de futilidad médica

This thesis examines the concept of medical futility and its importance for the practice of medicine nowadays. It presents an overview of the development of the concept throughout history and it discusses the main arguments in favor and against a determination of futile treatment in the clinical setting. The notion of futility, in broad terms, describes the situation in which certain medical interventions no longer benefit the patient and therefore, it follows that there must be a derived moral obligation to stop said intervention. Such an idea brings forward numerous problematic pitfalls that are discussed in this thesis, among which are the debate about the limits of medicine, the tension between the notions of patient autonomy and physician authority and the practice of medical rationing in hospitals. This thesis aims to provide a new perspective on the subject in hopes that it will help to keep the ongoing debate running so in the near future, more experts will decide to contribute themselves with their expertise. Situations where a medical intervention ceases to benefit the patient will continue to occur at the bedside; what is more, these ethical conundrums will become more and more problematic as the technological imperative intensifies and the possibilities of biotechnology increase. The leading question that directed the development of the thesis was “when enough it’s enough?” in other words, what are the ethical considerations on the limits of medicine? The paper concludes that the concept of medical futility has a heuristic value, and thus it has helped yield more clarity about relevant matters such as the differentiation between futility and rationing, the fact that more research is needed to test what works and what does not and it has brought to the spotlight the importance of more robust standards of practice that, for example, prevent physicians from practicing defensive medicine. Resumen: Esta tesis examina el concepto de futilidad médica y su importancia para la práctica de la medicina en la actualidad. Presenta una visión general del desarrollo del concepto a lo largo de la historia y discute los principales argumentos a favor y en contra de la determinación de un tratamiento fútil en el ámbito clínico. La noción de futilidad, en términos generales, describe la situación en la que ciertas intervenciones médicas ya no benefician al paciente y, por lo tanto, se deduce que debe existir una obligación moral derivada de detener dicha intervención. Esta idea plantea numerosos asuntos problemáticos que se discuten en esta tesis, entre los que se encuentran el debate sobre los límites de la medicina, la tensión entre las nociones de autonomía del paciente y autoridad del médico, y la práctica del racionamiento médico en los hospitales. Esta tesis pretende aportar una nueva perspectiva sobre el tema con la esperanza de que esta ayude a mantener el debate vigente, de manera que, en un futuro próximo, más expertos decidan aportar su experiencia. Las situaciones en las que una intervención médica deja de beneficiar al paciente seguirán; más aún, estos debates éticos se volverán cada vez más problemáticos a medida que se intensifique el imperativo tecnológico y aumenten las posibilidades de la biotecnología. La pregunta principal que dirigió el desarrollo de la tesis fue ""¿cuándo es momento de parar?"", es decir, ¿cuáles son las consideraciones éticas sobre los límites de la medicina? El documento concluye que el concepto de futilidad médica tiene un valor heurístico y, por lo tanto, ha contribuido a aclarar cuestiones pertinentes como la diferenciación entre futilidad y racionamiento, el hecho de que se necesita más investigación para probar lo que funciona y lo que no, y ha puesto de relieve la importancia de contar con normas de práctica más sólidas que, por ejemplo, impidan a los médicos practicar la medicina defensiva
