Normative theories of argumentation tend to assume that logical and dialectical rules suffice to ensure the rationality of argumentative discourse. Yet, in everyday debates people use arguments that seem valid in light of such rules but nonetheless biased and tendentious. This article seeks to show that the rationality of argumentation can only be fully promoted if we take into account its ethical dimension. To substantiate this claim, I review some of the empirical evidence indicating that people’s inferential reasoning is systematically (...) affected by a variety of biases and heuristics. Insofar as these cognitive illusions are typically unintentional, it appears that arguers may be biased despite their well-intended efforts to follow the rules of critical argumentation. Nevertheless, I argue that people remain responsible for the rationality of their arguments, given that there are a number of measures that they can (and ought to) take to avoid such distortions. I highlight the importance of argumentational virtues and critical thinking to rational debates, and describe a set of indirect strategies of “argumentative self-control”. (shrink)

In this article I argue that most biases in argumentation and decision-making can and should be counteracted. Although biases can prove beneficial in certain contexts, I contend that they are generally maladaptive and need correction. Yet critical thinking alone seems insufficient to mitigate biases in everyday contexts. I develop a contextualist approach, according to which cognitive debiasing strategies need to be supplemented by extra-psychic devices that rely on social and environmental constraints in order to promote rational reasoning. Finally, I examine (...) several examples of contextual debiasing strategies and show how they can contribute to enhance critical thinking at a cognitive level. (shrink)

In this paper, I argue that ordinary cases of self-deception and akrasia derive from the phenomenon of motivated irrationality. According to the ‘motivational’ account, self-deception is typically induced by the influence that desires and emotions exert upon our cognitive faculties, and thereby upon the process of belief formation. Crucially, I show that this hypothesis is consistent with the empirical research carried out by social psychologists, and that it avoids a number of paradoxes that undermine the ‘intentionalist’ account. But motivated irrationality (...) also seems to account for most cases of akrasia, insofar as desires are equally liable to affect the evaluative judgments through which we assess feasible options. This analysis thus set the premises for a unified account of irrationality. (shrink)

‘Intentionalist’ approaches portray self-deceivers as “akratic believers”, subjects who deliberately choose to believe p despite knowing that p is false. In this paper I argue that the intentionalist model leads to a number of paradoxes that seem to undermine it. I claim that these paradoxes can nevertheless be overcome in light of the rival hypothesis that self-deception is a non-intentional process that stems from the influence of emotions upon cognitive processes. Furthermore, I propose a motivational interpretation of the phenomenon of (...) ‘hyperbolic discounting bias’ which highlights the role of emotional biases in akratic behavior. Finally, I argue that we are not the helpless victims of our irrational attitudes, insofar as we have the ability – and arguably the epistemic obligation – to counteract motivational biases. (shrink)
