Abstract
In this paper, we examine the effect of making a choice on subsequent confidence. Using a simple binary forced-choice perceptual task, we show that committing to a decision results in perturbed probability (confidence) judgments compared to a control condition where no decision is elicited, suggesting that committing to a decision interferes with subsequent information processing. Current classical probability models of decision-making and confidence do not predict this interference effect, but it arises naturally out of a quantum random walk model. We show that this model provides a better fit to the data and provides novel predictions of interference as well as improved confidence accuracy following a decision.
