The prediction of future behavior: The empty promises of expert clinical and actuarial testimony
Testimony about the future dangerousness of a person has become a central staple
of many judicial processes. In settings such as bail, sentencing, and parole decisions,
in rulings about the civil confinement of the mentally ill, and in custody decisions
in a context of domestic violence, the assessment of a person’s propensity
towards physical or sexual violence is regarded as a deciding factor. These assessments
can be based on two forms of expert testimony: actuarial or clinical. The
purpose of this paper is to examine the scientific and epistemological basis of both
methods of prediction or risk assessment. My analysis will reveal that this kind of
expert testimony is scientifically baseless. The problems I will discuss will generate
a dilemma for factfinders: on the one hand, given the weak predictive abilities of
the branches of science involved, they should not admit expert clinical or actuarial
testimony as evidence; on the other hand, there is a very strong tradition and a vast
jurisprudence that supports the continued use of this kind of expert testimony. It is
a clear case of the not so uncommon conflict between science and legal tradition
Robot Mindreading and the Problem of Trust
This paper raises three questions regarding the attribution of beliefs, desires, and intentions to robots. The first one is whether humans in fact engage in robot mindreading. If they do, this raises a second question: does robot mindreading foster trust towards robots? Both of these questions are empirical, and I show that the available evidence is insufficient to answer them. Now, if we assume that the answer to both questions is affirmative, a third and more important question arises: should developers and engineers promote robot mindreading in view of their stated goal of enhancing transparency? My worry here is that by attempting to make robots more mind-readable, they are abandoning the project of understanding automatic decision processes. Features that enhance mind-readability are prone to make the factors that determine automatic decisions even more opaque than they already are. And current strategies to eliminate opacity do not enhance mind-readability. The last part of the paper discusses different ways to analyze this apparent trade-off and suggests that a possible solution must adopt tolerable degrees of opacity that depend on pragmatic factors connected to the level of trust required for the intended uses of the robot
The Pragmatic Turn in Explainable Artificial Intelligence (XAI)
In this paper I argue that the search for explainable models and interpretable decisions in AI must be reformulated in terms of the broader project of offering a pragmatic and naturalistic account of understanding in AI. Intuitively, the purpose of providing an explanation of a model or a decision is to make it understandable to its stakeholders. But without a previous grasp of what it means to say that an agent understands a model or a decision, the explanatory strategies will lack a well-defined goal. Aside from providing a clearer objective for XAI, focusing on understanding also allows us to relax the factivity condition on explanation, which is impossible to fulfill in many machine learning models, and to focus instead on the pragmatic conditions that determine the best fit between a model and the methods and devices deployed to understand it. After an examination of the different types of understanding discussed in the philosophical and psychological literature, I conclude that interpretative or approximation models not only provide the best way to achieve the objectual understanding of a machine learning model, but are also a necessary condition to achieve post hoc interpretability. This conclusion is partly based on the shortcomings of the purely functionalist approach to post hoc interpretability that seems to be predominant in most recent literature
Moore’s paradox and the logic of belief
Moore’s Paradox is a test case for any formal theory of belief. In Knowledge and Belief, Hintikka developed a multimodal logic for statements that express sentences containing the epistemic notions of knowledge and belief. His account purports to offer an explanation of the paradox. In this paper I argue that Hintikka’s interpretation of one of the doxastic operators is philosophically problematic and leads to an unnecessarily strong logical system. I offer a weaker alternative that captures in a more accurate way our logical intuitions about the notion of belief without sacrificing the possibility of providing an explanation for problematic cases such as Moore’s Paradox
ON COMMON GOOD, MONEY AND CREDIT
As Kosick maintained, homo oeconomicus is not only a theoretical aberration, it is an aberration of reality. The idea of human beings that Neo-classical Economics portrays is, without a doubt, a degeneration, and does little as the explicative axis of current society and even less in relation to the structural crisis in which we are living

Las medidas preventivas ambientales, una aproximaciĂłn desde el derecho administrativo
Las medidas preventivas previstas en el rĂ©gimen sancionatorio ambiental sonuna especie de las medidas cautelares consagradas en el ordenamiento jurĂdicocolombiano, aunque con algunas particularidades propias de su ámbito deaplicaciĂłn, que es el derecho ambiental. El artĂculo realiza una aproximaciĂłnrespecto al contenido, alcance, antecedentes y justificaciĂłn de las medidaspreventivas ambientales desde la Ăłptica del derecho administrativo y comomanifestaciĂłn de una de las funciones del ejecutivo, cual es el mantenimientodel orden pĂşblico
Endogenous Unions Formation
This paper analyzes the process of endogenous union formation in the context of a sequential bargaining model between a firm and several unions and tries to explain why workers may be represented by several unions of different sizes. We show that the equilibrium number of unions and their relative size depend on workers' attitudes toward the risk of unemployment and union configuration is independent of labor productivity.endogenous union formation, constant relative risk aversion, sequential bargaining, monopoly union
