Proponents of epistemic partiality in friendship argue that friendship makes demands of our epistemic lives that are at least inconsistent with the demands of epistemic propriety, and perhaps downright irrational. In this paper, I focus on the possibility that our commitments to our friends distort how we respond to testimony about them, their character, and their conduct. Sometimes friendship might require us to ignore (or substantially underweight) what others tell us about our friends. However, while this practice might help promote (...) your friendship and protect your friends, refusing someone’s testimony can constitute a special kind of insult towards them, according to Allen Hazlett (2017) and Finlay Malcolm (2018). It seems to follow that friendship can require us to insult people by refusing their testimony. This should count against treating your friends with epistemic partiality, one might think. It’s plausible that we have moral reasons not to insult other people, whether they’re our friends or not. The risk of insulting non-friends, it turns out, is just the beginning of the problems for the epistemic partiality in friendship. Recent discussions in social epistemology, led by Miranda Fricker (2007), Kristie Dotson (2011) and José Medina (2012), among others, have brought renewed attention the distinctly epistemic nature of some kinds of injustice. Drawing on this work, I’ll suggest a principled way to determine when epistemic partiality in friendship is morally impermissible because of the genuine risk of harmful epistemic injustice. -/- The paper proceeds as follows. First, I’ll argue that treating our friends with epistemic partiality can involve insulting other people by refusing their testimony. Then I’ll consider whether we ever ought to commit more morally serious testimonial injustices in the name of friendship. After considering some putative cases, I’ll introduce the concept of testimonial injustice, referring primarily to the work of Dotson (2011). I’ll explain how and why the epistemic bias which I’ve prescribed in friendship could be thought to cause such injustice. Drawing on the work of Sheila Lintott (2015), I’ll consider some ways in which the extent of the testimonial injustice caused by bias in friendship might be worse yet, namely, because of the role that homophily plays in determining who we become (and remain) friends with. In particular, I’ll consider whether epistemic partiality perpetuates racist or sexist forms of testimonial injustice. Finally, I’ll attempt to alleviate some of these concerns and determine when we’re morally required to treat friends with epistemic partiality. I’ll argue that whilst protecting a friend’s well-being might require you to cause testimonial injustice, such injustice would be morally unjustified. Accordingly, if you commit such injustice in the name of friendship, you’re morally blameworthy for doing so. This, I suggest, imposes an additional limit on epistemic partiality in friendship.
