Core Tip
Core Tip: While ChatGPT is an impressive tool, its conclusions still require human validation. Although ChatGPT identified typhoid fever with Guillain-Barré syndrome (GBS) as the most likely cause of Alexander the Great’s death, cross-checking both the available literature and the sources cited by ChatGPT revealed that Campylobacter jejuni, a more common and well-established cause of GBS, better fits the clinical and historical presentation. This study shows how artificial wisdom, which combines artificial intelligence with human judgment, can support more contextually accurate interpretations in historical medical investigations.
