We find that metacognitive ability is highly conserved for distinct preference-based decisions and we find some evidence for conservation across objective and subjective decisions.

Figure 4a from manuscript. It depicts a scatterplot relating the metacognitive ability parameter meta-uncertainty from the CASANDRE model from a delay discounting task and a risk and ambiguity task across participants.

This is difficult to do because these types of decisions do not have an objectively correct answer. However, by combining utility modeling and the CASANDRE model of confidence we can characterize metacognitive ability for these types of decisions in the same way we probe it for perceptual choices.

Figure 1d from manuscript, a cartoon description of the process model of confidence, CASANDRE, that can describe both objective and subjective decisions.
