In contrast, lower emotional granularity is associated with all sorts of afflictions. People who have major depressive disorder, social anxiety disorder, eating disorders, autism spectrum disorders, borderline personality disorder, or who just experience more anxiety and depressed feelings all tend to exhibit lower granularity for negative emotion. People who are diagnosed with schizophrenia exhibit low granularity for distinguishing positive from negative emotions. To be clear, nobody is claiming that low granularity causes these disorders, but it conceivably plays some role.
Autistic people tend to have atypical interoception, so low emotional granularity isn't surprising. But there are autistic experiences that cannot be adequately conveyed to neurotypicals: the joy of stimming and sensory overload come to mind.
