According to BellaOnline's Japanese Culture Editor, "The desire to know about blood type, started because of an assertion from the West, which stated that Asians were lower, in the evolutionary chain and that they were more closely related, to animals than other races." Interestingly, that was the start point where Asian countries became deep into the study of blood type.


Finding correlation between blood type and personality traits is one of popular theory in Asia countries, especially in Japan. Even though it has been disproved by Modern Science, some Japanese Scientist such as Furukawa Takeji still took it upon himself to scientifically by matching personality traits to blood type.
It was about 4 years ago in Korea when a movie, "Blood Type B" came out. In the movie, one guy with type B blood was described as a play body and a quick lover with non-responsibility. Because the movie was so popular at that time, many girls almost did not want to go out with a guy with type B blood. However, ironically, the percentage of blood type B is greater than the combination of all other blood types in Korea. I believe that the blood type theory regarding personality traits is almost not credible at all. In addition, the description about each blood type is so general that it could apply to everyone.
Following are the personality traits ascribed to the basic blood types. (If you know yours, try them)

Blood Type A:
Positive Traits: Conservative, introverted, reserved, patient, punctual and inclined to be perfectionists.
Worst Traits: Obsessive, stubborn, self-conscious and uptight.
Referred as 'farmers' in some descriptions, Type A's are said to be considerate of others and loyal to a fault. They can also be secretive and reluctant to share their feelings. Apparently they don't hold their liquor well, either.

Blood Type B:
Type B men have acquired a very negative reputation in Korea and are not considered by many to be good husband material. Often described as 'players', they are perceived as being selfish and mercurial, quick to anger and not terribly reliable. That said, their bad boy image makes them very attractive to women, but not for the long term. (Type B women do not share in this bad rep, for some unexplained reason).

Blood Type AB:
Referred to as 'humanists', Type AB's are said to be controlled more by their heads, than by their hearts. They are rational, good with money, but unpredictable. Although inclined to be distant, they prefer harmony and as such, work well with mediators. Some consider them two-faced, and therefore untrustworthy.

Blood Type O:
Referred to as 'warriors', Type O's are viewed as natural leaders and are often, also, natural athletes. They tend to be outgoing, expressive and passionate, but can also bore others to death with their obsessive drive for success coupled with their absolute convictions that they are winners. This certainty that they will always win explains why they aren't afraid to take risks or gamble. They have a strong physical presence and are unlikely to ever be overlooked.
If you have known and tried them, do you think there is correlation between the personality traits and blood type?

IQ Score Matter?

Vote 0 Votes

The term IQ, or Intelligence Quotient, generally explains a score on a test that rates the subject's cognitive ability. I remember that I took an IQ test when I was in the middle school. At that time, I believe that the high IQ is the most important factor to be outstanding compared to other students in academic performance. However, there were some exception cases; my teacher mentioned that she was surprised to see that some students with the low IQ score were very good at other mathematics tests.
I still somewhat believe that there is a bit correlation between IQ and job performance. In addition, it is mentioned in the Chapter 9 that IQ scores predict performance across a wide variety of occupations, with the average correlation about 0.5. In addition the correlation between IQ and job performance is even higher among the jobs that require more mentally demanding occupations such as physician or lawyer. Many psychological studies support the correlation between a high IQ score and performance at work. From my experience, I observe that employers, especially in companies in Korea, frequently use the IQ score or a score on a test that the companies develop to identify the best candidates.

However, some people argue that the IQ score is not an absolute factor that can decide performance at work. In addition, they argue that there are other sociological factors such as personality, peer relation and communication skills besides the IQ scores might be playing a bigger role in performance at work.
Do you think that high IQ scores mostly matter to achieve better work performance? Or other sociological factors mostly matter?
