New paper! Accepted at Perspectives on Psychological Science. A textbook finding in infant psychology is that newborns - within ~1 hour of birth - visually track a simplified 'three blob' facelike stimulus further than its inverted control (see picture). This suggested inborn knowledge of faces!
a simplified facelike stimulus consisting of three blobs for eyes and mouth on a head-shaped background, and its non-facelike control stimulus with the blobs inverted upside down.

Why do people with ME claim to know more about the medical aspects of their disease than their doctors? Because the mechanisms that usually ensure doctors' knowledge fail in the case of ME, and sick people have created mechanisms of knowledge production and dissemination to pick up the slack.

Epistemic Assholes
Cameron Boult
Synthese (forthcoming)

Abstract
In this paper, I develop and defend the concept epistemic assholes. An epistemic asshole is someone who exhibits a distinctive form of epistemic badness characterized not by gross irrationality or hostility to truth, but by a stable, entitled disregard for one’s epistemic relations with others. Drawing on Aaron James’s (2012) account of moral assholes, I examine how people can systematically exploit epistemic cooperation by allowing themselves special advantages—such as “freedom from inquiry”, “doxastic comfort”, and “freedom to criticize”—while remaining insulated from criticism by an entrenched sense of entitlement. The resulting view, the Relational Approach to Epistemic Assholes (REA), explains why epistemic assholes are not epistemically the worst, yet are nonetheless deeply galling. After motivating the need for this concept, I show how REA captures both “impure” cases (involving both epistemic and moral assholery) and “pure” epistemic assholes, whose objectionable conduct is driven by epistemic aims themselves. I further explore connections between epistemic assholes and epistemic vice, and the causal role that epistemic assholery can play in active ignorance and epistemic exploitation. Through this latter connection, I argue that epistemic assholes play an insidious causal role in sustaining objectionable social power dynamics. The concept of epistemic assholes provides a valuable lens for understanding and calling out important but often-hidden hazards in our social epistemic environment.
