To my surprise, an interview of Professor Maekawa, a friend of mine, is in the article.
This is useful, because it explains that blood type and personality is a kind of "taboo" in English language world.
For example:
Theorists of eugenics later hijacked his [Karl Landsteiner] research ... with the Nazis using his work to further their ideas of racial supremacy.
It [blood type and personality] was also adopted by Japan's militarist government in the 1930s to train better soldiers, and during World War II, the Imperial Army is reported to have formed battle groups according to blood type.But one thing is definitely different from the others.
The article quoted Professor Maekawa's words like this:
A type societies tend to be characterized by monotheism such as Christianity and Judaism, with one fundamental analysis of human beings and a strong sense of societal norms. But societies dominated by B types are more prone to polytheism - like Buddhism and Hinduism - with lots of gods, and they think people are all different.Fantastic!!
I wonder why this writer doesn't approve the relation between blood type and personality?
I mailed to Mr. Maekawa about this issue and will get the answer from him before long.
