Blood type horoscope cards in Japan
The blood type personality theory[1] is a pseudoscientific belief prevalent in Japan which states that a person's blood group system is predictive of a person's personality, temperament, and compatibility with others.[2] The theory is generally considered a superstition by the scientific community.
One of the reasons Japan developed the blood type personality indicator theory was in reaction to a claim from German scientist Emil von Dungern, that Blood type B people were inferior.[3] The popular belief originates with publications by Masahiko Nomi in the 1970s.
Although some medical hypotheses have been proposed in support of blood type personality theory,[4] the scientific community generally dismisses blood type personality theories as superstition or pseudoscience because of lack of evidence or testable criteria.[2][5][6] Although research into the causal link between blood type and personality is limited, the majority of modern studies do not demonstrate any statistically significant association between the two.[7][8][9][10] Some studies suggest that there is a statistically significant relationship between blood type and personality, although it is unclear if this is simply due to a self-fulfilling prophecy.[11][12][13]

^Takeji Furukawa (1927), 血液型と気質 Blood Type and Temperament - in Europe, type A was more common than type B, while in Asia type B was more prevalent. Von Dungren claimed A people are superior to B people. Because Asia had more B people than some parts of Europe, the inference was that Asia was inferior (along with European B's) A Japanese scholar, Takeji Furukawa opposed that idea and asserted that B persons were active while A persons were passive.
