Wonder of genes: Why do we feel blood type [and personality] is true? by Satoshi Komiri

Here comes a kindle book (in Japanese) by Toshi Komori who retired from Toshiba and entered the graduate school of Tokyo University.
The book is not full of formula nor difficult, but a science reading which can be read with ease.


However, this title can cause some misunderstanding.
The "correct" one is "blood type [and personality] is true". Wow!

The Compatibility Matrix by Ms. Heather Collins Grattan

I gracefully got a comment and an email from the author (Type B woman).

The Compatibility Matrix: The Qualities of YOUR Ideal Mate
by Heather Collins Grattan (Author), Joseph Christiano (Foreword)


This book is a romantic book of seeking the ideal partner, that devotes whole chapter 8 to the blood type. What is different from Japan is that there are religion and politics in the elements of compatibility (Compatibility Matrix).

She adopts a method of summing up the scores of each element and judging compatibility. Whether it is American style or Type B style, I wonder. By the way, its blood-type compatibility closely matches Mr. Nomi's "lead = care relationship".

Perhaps this book may be sold if well translated into Japanese.

Listen to Koreans: Which blood type would you like to be the best lover?

From Yahoo! JAPAN News on 9/19/2017

According to an article of the Korean major newspaper "Chosun Ilbo" (2017/9/19), the blood Type AB  takes the first place (43.5%) as the best lover, the second is Type B (33.6%). By the way, Type O is 13.6% as the 3rd place, Type A, the largest population, is only the lowest 9.0%.

Source: the same article

Korean blood group ratio is 34% A, 28% O, 27% B and 11% AB, so Type AB is the smallest number blood group as same as Japan.

I understand that Type-AB people with "rare value" are the most popular in Korea.
However, since Type-O is the most popular in Japan, unlike Korea, minorities are not necessarily popular. Is that the difference in national character?
By the way, Type A is popular for with the boss in Korea.

Do Type-O Italians Live Longer?

Some Italian paper says Type-O Italians live loger.
Reseachers examined the blood type of centenarians. Type O is accounted for 56.4%, which exceeds 43.5% of the national average.
Since the total number of subjects was as many as 5063, the result is statistically significant.
However, a previous survey of Tokyo (2004), type B was said to live longer.
This Italian result does not agree with the the Japanese.


Franchini M, Mengoli C, Bonfanti C, Rossi C, Lippi G.
Genetic determinants of extreme longevity: the role of ABO blood group.
Thromb Haemost. 2016 Jan;115(2):458-60. doi: 10.1160/TH15-05-0379. Epub 2015 Sep 3.
A statistically significant difference in the distribution of ABO blood groups between the cohorts of centenarians and donors was found (Pearson Chi-square test [3 d. o.f] = 10.71, p = 0.007). The significance was mainly due to a higher prevalence of O blood type in centenarians compared with controls (56.4 % vs 43.5 %, Pearson Chisquare test [1 d. o.f] = 10.78, p = 0.0010)

Czech paper

This time I will introduce a Czech paper.

It said that there was no difference according to ABO blood group in personality test (Big Five).
Subjects were 502 soldiers in the Czech Republic.
This result (no difference) is as expected, but there was a difference in RH blood type somehow ...
Anyway, we can read the paper free of charge.


Jaroslav Flegr et al., (2013), Toxoplasmosis-Associated Difference in Intelligence and Personality in Men Depends on Their Rhesus Blood Group but Not ABO Blood Group
PLoS One. 2013; 8(4): e61272.
Published online 2013 Apr 10. doi: 10.1371/journal.pone.0061272
  • Here, we searched for differences in the toxoplasmosis-associated effects between RhD-positive and RhD-negative subjects by testing 502 soldiers with two personality tests and two intelligence tests. The infected subjects expressed lower levels of all potentially pathognomic factors measured with the N-70 questionnaire and in neurasthenia measured with NEO-PI-R.
  • The analyses showed significant effect of RhD phenotype-toxoplasmosis interaction on psychasteny and IQ and no significant effects of ABO phenotype or ABO phenotype interaction (Tab. 3).
