Active Exploration of Explanations as a Guard Against Overconfidence in Understanding

Shiffrin et al. identify a wide-ranging set of illusions of understanding in the sciences. I argue that their analysis can be sharpened by distinguishing three partially overlapping sources of unwarranted confidence: the open-ended nature of explanation, the cognitive limitations of the human mind, and features of contemporary scientific practice. The first two sources are structural features of inquiry itself and have historically been mitigated-though never eliminated-by corrective mechanisms embedded in the scientific method, such as systematic error detection and active exploration of explanations. The third source-societal and institutional conditions-differs in kind: it can either strengthen or weaken these corrective mechanisms, thereby either reducing or amplifying illusions of understanding. Clarifying this distinction helps specify both the structural resilience and the contingent vulnerability of scientific inquiry.
