Introduction

As Masahiko Nomi, Toshitaka Nomi and Alexander besher once said,

blood types and personality are obviously related.

This is a conclusion from top 10 large-scale surveys, too.

We may have discovered the secret of genes, little by little ...

Results of Large-Scale Surveys over 300,000 People are ALL POSITIVE

How can we examine whether blood types and personality are related?

The easiest way is to ask questions about personality and see if there are differences by blood types.

 

Well, not only budget, but time and efforts are serious issues to conduct a large questionnaire. However, the world seems to be quite large. Ask, it will be given!

Papers of psychology and reports of Grants-in-Aid for Scientific Research (of Japan) are surprising blind spots.

 

According to the book "Why are type B women so popular ? -- 300,000 people solved the mystery of blood types" by Masayuki Kanazawa (*1), most of large-scale surveys of "blood types and personality" clearly show positive results.

 

(Excerpts) [Regarding blood types and personality] Results of top 10 large-scale surveys are examined if there are any differences in statistical data.

(Abbreviation)

When comparing all the 10 surveys, 9 (90%) of them showed positive [Difference=Yes] results. Comparing the number of subjects, about 330,000 [324,037] people (96.5%) out of total 340,000 [335,766] are so. Therefore, we can say that positive results are overwhelming.

According to Mr. Kanazawa, differences in each large-scale data are found EXCEPT Mr. Nawata's  of the sixth place (in red). As you can see from the table above, question items of his paper are limited to money and lifestyle, have nothing to do with personality. On the other hand, all the other nine surveys have question items about personality. In other words, no difference comes out because Mr. Nawata's question items are not of personality ...

This result is also the same of a Korea's consumer behavior survey (*2). The nature of Korean consumers is thought to differ by their blood types, but actually, little difference is found in the questionnaire on consumption behavior. Question items are  not directly related to personality.
