Moral discourse boosts confidence in moral judgments

Decision Making in Moral Judgment Context is Modulated by Individual Metacognition

Metacognition refers to the human capacity to access and monitor one's own mental states. Recent research suggests that this capacity expands to the social world, e.g., when individuals explicitly share their cognitive processes with others. Additionally, metacognition is also linked to cognitive flexibility, and the latter to ideologically radical behaviors. Indeed, the absence of control over one's own mental activity could be at the base of different phenomena linked to social cognition. We investigate the metacognitive capacity of individuals in relation to the radicality with which they make a moral choice (utilitarian vs. deontological). For this purpose, 76 participants were submitted to 24 hypothetical situations, with the aim of evaluating the consistency (i.e., the radicality) of their moral choices. Then, in an independent experimental session, we evaluated the participants' metacognitive efficiency. We managed to demonstrate that individual metacognition scores are correlated with the radicality of a moral choice. We discussed the impact and relevance of metacognition in ecological contexts, particularly where subjective evaluation of the environment involves individual choices with social consequences.

Deliberation and confidence change

We argue that social deliberation may increase an agent's confidence and credence under certain circumstances. An agent considers a proposition H and assigns a probability to it. However, she is not fully confident that she herself is reliable in this assignment. She then endorses H during deliberation with another person, expecting him to raise serious objections. To her surprise, however, the other person does not raise any objections to H. How should her attitudes toward H change? It seems plausible that she should (i) increase the credence she assigns to H and, at the same time, (ii) increase the reliability she assigns to herself concerning H (i.e. her confidence). A Bayesian model helps us to investigate under what conditions, if any, this is rational.
