Although inaccurate metacognition impairs decision-making, its sources are still debated. Early theories suggest a hierar- chical metacognitive structure where a domain-general system shapes domain-specific metacognitive processes. Recent the- ory attributes metacognitive inaccuracy to systematic errors in the computation of decision-making confidence. The present study combines these two theories to examine the extent to which general and specific systems affect decision-making con- fidence, and therefore metacognitive accuracy. The results show evidence for domain-general and domain-specific sources of metacognitive accuracy. Impulsivity has domain-general ef- fects on decision-making confidence and metacognitive accu- racy, while the tendency to consider suboptimal choices has domain-specific effects
