Psychopathology and literary creativity: a pathographical mixed-methods analysis of the tang dynasty poet Li Bai

The Tang dynasty poet Li Bai (701-762 CE) is renowned for extraordinary literary creativity. Traditional historical perspectives frequently link his "Poet Immortal" reputation to alcohol-associated euphoria. We examined whether temporal fluctuations in his creative output co-occurred with biographical and textual features compatible with mood-spectrum psychopathology, while considering alcohol use and major life events as alternative explanations.

This retrospective pathographical mixed-methods study analyzed Li Bai's literary corpus and biographical archives. Annual creative output was quantified for 836 securely dated poems across a 48-year career. Years exceeding 2 SDs above the career mean were used as data-derived anchors for episode-centered qualitative review. We additionally calculated the proportion of the corpus produced in peak years and a peak-to-nonpeak productivity ratio. Literary and historical evidence was then mapped to DSM-5 mood-episode symptom domains, with explicit attention to temporal fit and competing situational explanations.

Annual productivity showed three extreme-output years: 743 CE (n = 73, z = 3.29), 753 CE (n = 56, z = 2.29), and 759 CE (n = 63, z = 2.70). These 3 years (6.25% of career years) contained 192 poems (23.0% of the securely dated corpus); mean output was 64.0 poems/year in peak years versus 14.3 poems/year in the remaining years (ratio, 4.47). Episode-centered review found the strongest convergence of elevated or expansive affect, grandiose self-appraisal, and reckless behavior around 742-743 and 752-753 CE. The 758-759 CE episode included marked elation after an imperial pardon, although this event provides a strong nonpathological explanation for the affective shift. Depressive and mixed-affect expressions were also present. The temporal convergence is compatible with, but does not establish, a bipolar-spectrum interpretation or a causal effect of mood symptoms on creativity.

Li Bai's creative output was highly episodic, and the identified productivity bursts temporally overlapped with certain literary and biographical characteristics consistent with mood elevation. Therefore, the combination of genius and bipolar disorder is more likely to explain Li Bai's literary achievements, rather than the combination of genius and alcohol. Li Bai's case should no longer be used as a positive example of drinking in the name of "creativity".
