Title:
Signatures of a Statistical Computation in the Human Sense of Confidence
Abstract:
Human confidence judgments are thought to originate from metacognitive processes that
provide a subjective assessment about one's beliefs. Alternatively, confidence is
framed in mathematics as an objective statistical quantity: the probability that a chosen
hypothesis is correct. Despite similar terminology, it remains unclear whether the
subjective feeling of confidence is related to the objective, statistical computation of
confidence. To address this, we collected confidence reports from humans performing
perceptual and knowledge-based psychometric decision tasks. We observed two
counterintuitive patterns relating confidence to choice and evidence: apparent
overconfidence in choices based on uninformative evidence, and decreasing confidence with
increasing evidence strength for erroneous choices. We show that these patterns lawfully
arise from statistical confidence, and therefore occur even for perfectly calibrated
confidence measures. Furthermore, statistical confidence quantitatively accounted for
human confidence in our tasks without necessitating heuristic operations. Accordingly, we
suggest that the human feeling of confidence originates from a mental computation of
statistical confidence.
