Introduction to Blood Type and Personality (Modified on April 29, 2018)

It was Mr. Masahiko NOMI, a journalist hometown, that made the present Japanese blood-type boom. His first blood-type book, "Ketsueki-gata de wakaru aisho" (Understand compatibility through blood type) became one of the best sellers in 1971. He wrote more than ten books which became best sellers or long sellers. After he passed away in 1981, his son, Mr. Toshitaka NOMI took over (he passed away in 2006). Now the Human Science ABO Center had succeeded their research.
Statistical relationship between blood type and personality are testified by many Japanese studies as well as Korean studies.

First season: As for relation between blood type and personality, results differs by questionnaires. Therefore, it continued to bother researchers. Now, I may have testified the consistent relation, if my reasoning is correct. But I'm not Holmes nor Poirot.
Please judge whether I am collect or not. Take it easy and enjoy my reasoning! It is you that is Sherlock Holmes!

Second season: In the second season, I try to solve the remaining mysteries: 1. Are detected personalities are real or imaginary? Why psychological personality test cannot detect the differences by blood type?  This time, you are Ellery Queen!

Prof. Matsui's Papers

Finally I obtained the papers of Mr. Matsui (Prof. of Sacred Heart Women's University). They are really fantastic! The data showed consistent results "as expected". Wow!!
However, Mr. Matsui thinks there is no relaiontion between blood types and personality. Please enjoy reading!  Click Here!

Prof. Sakamoto's Papers

As far as I know, Prof. Sakamoto's papers analyized the largest number of samples: more than 30,000 people using the random sampling method. Of course, they showed the clear difference between blood types.  But Mr. Sakamoto said "blood-typical stereotypes" caused the difference, not blood types themselves. So he think there is no relaiontion between blood types and personality. However...  Click Here!

Ms. Watanabe's Papers (March 18, 2007)

Ms. Yoriko Watanabe's paper is very epoch-making.  In short, knowledge of blood type and personality ("blood type stereotypes") doesn't influence his/her answers of personality questionnaire.  So, the difference is "real" not "blood type stereotypes".
Also wonderful differences appear unless one does not use psychological personality tests.  Click Here!

Blood-type Scores

Reading Prof. Matsui's paper and Prof. Samamoto's paper, I think principal component analysis or discriminant function is suited for analyzing the data.  But I found no such papers -- even now.  Why?  So I'm going to try!  Click Here!

Prof. Saitou' Papers

There seems to be some interesting and new findings. Click Here!

• Allelic nucleotide differences for the human ABO genes correspond to several million years.
• Comparing human and nonhuman primate ABO alleles, at least three independent appearances of B alleles from the ancestral A form.
• Alleles O are identical to alleles A except for the single nucleotide deletion, which suggests appearances of O alleles from the ancestral A form.

Prof. Ohmura and Cloninger's Personality Dimensions  (March 18, 2007)

Professor Ohmura who is famous honorary professor of Nihon University, once said the he got consistent results using Cloninger's Personality Dimensions.  Though the results was televised twice in 2004, no articles shown -- till now.  Why?  Click Here!

Raymond B. Cattell's Study

Famous psychologist, Raymond B. Cattell's study shows the clear relation of blood types to personality traits. Click here!

Results of The ABO System

• TYPE-AB is more self-sufficient and group-independent (probability < 5 percents)
• TYPE-A is more anxious than TYPE-O (probability < 1 percent)

Excerpts from "The relation of blood types to primary and secondary personality traits." The Mankind Quarterly, pp35-51, Vol. 21, 1980.

SUMMARY

A sample of 323 Caucasian Australians was chracterized with respect to 17 genetic systems (7 blood groups, 5 crythrocyte enzymes and 5 plasma proteins) and 21 psychological variables (16 primary and 5 secondary personality factors). The mean age corrected psychological scores were determined for each phenotype and comparisons within systems yielded 13 significant differences a to .05 level and 11 at .01 level. The most conclusive finding occurred in the P system: the four primaries producing differences a to .01 level (C, H, Q3, and Q4) are those entering into the second order anxiety factor QII, which yielded the greatest difference observed in the study (p<.001).

Study in Taiwan (March 18, 2007)

To my surprise, I find a blood type study in Taiwan!
Dr. Wu, the author, is a professor of medical college in Takao prefecture, Taiwan.
NEO - PI - R test itself cannot detect the differences of blood type -- maybe.  Click here!

Information from  Korea (June 20, 2008)

 The latest study done by Young Woo Sohn, Yonsei University Professor (psychology), is really epoch making!
<Seoul, Yonhap News Agency> As a result of putting many blood-type personality studies together, type O is tend to be extravert, while type is A introvert.  In most studies, type A is logical and emotionally stable, but type B -- in comparison with other blood types -- is sensitive.  Click here!

Scientific American's guest blog on Feb. 15, 2011 (July 31, 2012)

This article concluded a negative result.  But, this is NOT correct -- at least statistically.
According to the writer "preexisting blood type belief" now penetrated into all around Taiwan and South Korea as well as Japan (Japanese found 75 percent believed in ketsueki-gata).
Therefore ALL studies in these three countries MUST show significant statistical relationships between personality and blood type, and they really do. Because these studies are based on "self-reported" personality.  Click here!
