One day, the A, the B, the O, and the AB promised to go to the beach together. Approximately, who is the most on time, and who is the least on time?If you can answer that question, that means you believe in a blood type! Maybe you guys have read that: blood group A is on time, blood group B is a lazy one, blood group O likes to act as good as a soul, while blood group AB is…weird. Hmm… so as our friend asked, does blood type determine our traits?
Fact or Myth?
Blood type can be popular, but it’s just a myth. In the previous article, we learned about the Barnum Effect. This concept also applies to blood type. The match between our actions and blood grouping can also be explained by the term Self-fulfilling Prophecy. That is, something that we thought could happen because that’s what we were hoping for.
But if it’s a myth, why do our friends in the same blood group have the same traits? Well, this phenomenon can also be explained by the term Confirmation-bias. That is, as humans, we tend to like to look for information that can support our beliefs. For example, we believe blood type A people are very disciplined.
We became more and more sure when we saw our girlfriend with blood type A was never late for the ceremony on Monday. But in class, she often forgets to do his homework.
In addition, the relationship between the traits and type of blood has not been scientifically proven. In 1927, research on blood type and personality was conducted by a Japanese professor of psychology named Takeji Furukawa.
However, this research is considered less valid because it is highly politically charged. In short, at that time Japan was expanding its spirit to other countries in East Asia. Well, compared to others, Taiwanese people were very difficult to subdue.
With his research, Professor Furukawa wants to find out the secrets characteristic of Taiwanese rabid personalities in the Japanese government.
A Half Century Later…
Half a century later, the book blood and personality came out. This book was written by Masahiko Nomi, a journalist with no medical or psychological background.
Although it is not valid, Nomi’s book is filled with various data and convincing statistics. Finally, the classification of traits based on blood type became more and more popular in East Asian societies.
So, if Americans like to read horoscopes, the Japanese have Ketsueki-gata! In Japan, the classification of traits based on blood type is even a guideline for many matchmaking agencies.
The popularity of gata is increasing through popular culture such as South Korea’s comic book webtoon Park Dongsun. And… thank you for the sophistication of 21st century IT technology, now we also know these funny characters in the United States.
As long as it’s just funny, classifying by blood type can indeed be entertainment. But for those of you who are still using this method to pay off a potential boyfriend or girlfriend, it is better to have determination and courage. If you could ask them directly, what would you guess? Does blood type really determine our traits?
