It is common to view appeals to popularity as fallacious. We argue this is a mistake and that Condorcet’s jury theorem can be used to justify at least some appeals to popularity as legitimate inferences. More importantly, the conditions for the application of Condorcet’s theorem can be used as critical tools when evaluating appeals to popularity. The application of these three concepts to appeals to popularity provide a more fine-grained critical strategy for argument evaluation and, also, allow us to see (...) the real problems that often arise with such appeals more clearly.

In this paper we aim at discussing cognitive and epistemic features of online communities, by the use of cognitive niche constructions theories, presenting them as virtual cognitive niches. Virtual cognitive niches can be considered as digitally-encoded collaborative distributions of diverse types of information into an environment performed by agents to aid thinking and reasoning about some target domain. Discussing this definition, we will also consider how online communities, as networks displaying a social bias, can both foster civic awareness and promote (...) problematic group-led behaviors in the virtually aggregated crowds. To support this affirmation, we will take into account the use of online communication networks during crises and we will argue that it can lead to ethically dubious consequences. (shrink)

What should a virtue theory of argumentation say about fallacious reasoning? If good arguments are virtuous, then fallacies are vicious. Yet fallacies cannot just be identified with vices, since vices are dispositional properties of agents whereas fallacies are types of argument. Rather, if the normativity of good argumentation is explicable in terms of virtues, we should expect the wrongness of bad argumentation to be explicable in terms of vices. This approach is defended through analysis of several fallacies, with particular emphasis (...) on the ad misericordiam. (shrink)
