“Overestimation of Interoceptive Ability Linked to Lower Metacognitive Skills”

https://pubmed.ncbi.nlm.nih.gov/38113709

This study found that individuals who believe they are good at perceiving their own interoceptive experiences (such as heartbeat) tend to overestimate their abilities, and this misjudgment is associated with lower interoceptive metacognitive skills.
