Everyone has blood that it can be divided into four main types: A, B, AB and O. There are many predictions about personality of each blood type. Here are some examples of blood type and personality, based on James and Peter D’Adamo’s work:

-          Blood Type A - Tend to be cooperative, sensitive, clever, passionate and smart.

-          Blood Type B - Tend to be balanced: thoughtful like A's and yet ambitious like O's.

-          Blood Type AB - Tend to be very charming and popular. 

-          Blood Type O - Tend to be loners or leaders and are intuitive, focused, self-reliant and daring.

Why do some people believe that blood type can predict the character of our peoples?

The origins of the faith of “the blood type can predict habits” come from Japan written by Rin Hirano and Tomita Yashima. In the book confirm that there is a relationship between blood type and personality. After that, scientists found that it is not scientifically based. And without statistical data. Then, I am going to show my result about the effects by using a questionnaire.

Questionnaire

The picture shows the questionnaire which I used to collect the data. Finally, I have got the result of this experiment. We collected data from 15 people who is study at Darunsikkhalai Science School has shown.

	1st choice	2nd choice	3rd choice	4th choice
A			2
B	4			2
AB	2			3
O		2

From the result, there are 15 participants and no one chose the choice which it's matching with personality of own blood type like James and Peter D’Adamo’s work.

       

Conclusion 

In conclusion, we can say that blood type has no any relationship with personality. The character of each person depending on surroundings, parents, society or individual favor. However, this experiment has been surveyed just 15 people, it may cause a high percentage of the error.

“Blood type is divided by antigen, which is on the red blood cell surface, and it's unrelated with your traits” – Science Here Here facebook fanpage said.
