However, the effect magnitude was extremely small, despite 'significance' in the statistical sense.Another Japanese social psychologist, Shigeyuki Yamaoka (Shotoku University), announced results of his questionnaires, which were conducted in 1999 (1,300 subjects) In both cases, the subjects were university students, and only subjects with enough knowledge of and belief in the "blood-type diagnosis" showed meaningful differences.His reasoning was supported by the fact that among the Ainu, whose temperament was characterized as submissive, only 23.8% had type O.In conclusion, Furukawa suggested that the Japanese should increase intermarriage with the Taiwanese to reduce the number of Taiwanese with type O blood. It was revived in the 1970s with a book by Masahiko Nomi, a journalist with no medical background (he graduated from the engineering department of University of Tokyo).However, Kanazawa was not able to discover any association with blood-type differences and penetration rates.This result raises doubt about the role of beliefs and self-fulfilling prophecy.In another study, Furukawa compared the distribution of blood types among two ethnic groups: the Formosans in Taiwan and the Ainu of Hokkaidō.
Therefore, the blood type explained only 0.3% of the whole differences of these data sets.
Insurgencies in 1930 and in 1931 resulted in the deaths of hundreds of Japanese settlers.
The purpose of Furukawa's studies was to "penetrate the essence of the racial traits of the Taiwanese, who recently revolted and behaved so cruelly." Based on a finding that 41.2% of Taiwanese samples had type O blood, Furukawa assumed that the Taiwanese rebelliousness was genetic.
He concluded that these differences must be the influence of mass media, especially TV programs.
Yamaoka later examined 6,660 samples from 1999 through 2009 in total and found the same result.
In 1927, Takeji Furukawa, a professor at Tokyo Women's Teacher's School, published his paper "The Study of Temperament Through Blood Type" in the scholarly journal Psychological Research.
