It explores the military physicians’ quest to investigate the relevance of blood-group knowledge and their attempt to integrate ideas derived from Furukawa Takeji’s Blood Type–Temperament Correlation Theory—the idea that blood type is linked to personality traits—into the operations of the armed forces, a process I term ‘sero-rationalization’. By the mid-1930s, however, escalating conflicts prompted a shift in research priorities. Military physicians increasingly focused on serology and the technological advancements required for blood transfusions, moving away from earlier biopsychological discussions of blood types. This shift reflected an urgent need to address wartime medical challenges, including treating injuries and developing reliable transfusion methods. With the intensification of war by the 1940s, frontline physicians began exploring alternatives to traditional blood typing, such as cross-type transfusions and even animal-to-human transfusions. In their attempts to circumvent the ABO blood-group system in dealing with wartime medical emergencies, military physicians departed significantly from their initial emphasis on serological differentiation. Ironically, the pursuit of sero-rationalization—intended to optimize military efficiency—ultimately proved counterproductive.- Reproduced https://www.cambridge.org/core/journals/modern-asian-studies/article/abs/serorationalization-of-the-imperial-japanese-military-19261945/E5BA97E81A8700A9EF6A9FD199942EA3
