This article examines the role of expertise in public debate, specifically the ways in which expertise can be mimicked and deployed as “pseudo-expert discourse” to generate legitimacy for views that have otherwise been discredited. The article argues that pseudo-expert discourse having a clear public health or safety impact should be regulated. There have been some attempts to legally regulate this speech through various means; however, these attempts at regulation have been met with fierce resistance, because of free-speech concerns. The article (...) suggests that these appeals to free speech in the context of pseudo-expert discourse are both misguided and misplaced. Moreover, because speakers with the relevant expertise or perceived expertise are able to secure uptake of their views, they have a moral responsibility to not deceive or mislead audiences, and may also have various legal responsibilities.

I consider some uses of citations in academic writing and analyze them as instances of the “appeal to expert opinion” argumentative scheme to show that the critical questions commonly linked to this scheme are difficult to apply. I argue that, by considering citations as special communicative and argumentative situated acts, their use in real practice can be explained more adequately. Adaptation to the audience and to the social constraints is common and necessary in order to collaborate with others and to (...) advance in a discipline, but also to attain rhetorical goals that differ from strictly cognitive ones.

The Linda paradox is a key topic in current debates on the rationality of human reasoning and its limitations. We present a novel analysis of this paradox, based on the notion of verisimilitude as studied in the philosophy of science. The comparison with an alternative analysis based on probabilistic confirmation suggests how to overcome some problems of our account by introducing an adequately defined notion of verisimilitudinarian confirmation.
