The novice/expert problem is the problem of knowing which apparent expert to trust. Following Alvin Goldman’s lead, a number of philosophers have developed criteria that novices can use to distinguish more from less trustworthy experts. While the criteria the philosophers have identified are indeed useful in guiding expert choice, I argue, they can’t do the work that Goldman and his successors want from them: avoid a kind of testimonial scepticism. We can’t deploy them in the way needed to avoid such (...) scepticism, because it would take genuine expertise to do so. I argue that attempts to deploy them in this sort of deep way involve a kind of transgression akin to, and at least as unreliable as, epistemic trespassing. We should give up trying to solve the novice/expert problem and instead promote better epistemic trust. (shrink)

The world is abuzz with experts who can help us in domains where we understand too little to help ourselves. But sometimes experts in one domain carry their privileged status into domains outside their specialization, where they give advice or otherwise presume to speak authoritatively. Ballantyne calls these boundary crossings “epistemic trespassing” and argues that they often violate epistemic norms. In the few cases where traveling in other domains is permissible, Ballantyne suggests there should be regulative checks for the experts (...) who are crossing domain boundaries. I argue that boundary crossing is warranted more often than Ballantyne allows. And while Ballantyne argues that boundary crossing is prima facie epistemically problematic, I contend that many cases of boundary crossing are not properly instances of “trespassing,” and, therefore, raise no prima facie epistemic concerns. I further argue that identifying cases of what I call “epistemic neighborliness” bolsters Ballantyne’s project, making it easier for novices and other experts to identify epistemic trespassing along with its epistemic problems.

The term ‘epistemic trespassing’ has recently been coined to denote a person’s judgments regarding a domain where they are not epistemic experts. In this paper, I focus on expert trespassing testimony – that is, testimony by an expert in a domain of expertise other than his own. More specifically, I focus on intra-scientific trespassing testimony between scientific collaborators. By developing a number of distinctions, I argue that while intra-scientific trespassing testimony may seriously hamper scientific collaboration, it does not invariably do (...) so and may even be beneficial to it.
