Relationship between brain activity and blood types -- through experiments

The ABO Center and Dr. Munetaka Haida (Tokai University) have collaborated on experiments about relationship between brain function and blood types for over 10 years.
According to the article, in experiments using a "optical topography device" to measure the activity of the brain, comparing Type A and Type B, the workings of the left brain and the right brain show a spectacular contrast.

Type A = activity amount of left brain is high
Type B = activity amount of right brain is high

Also, there was somewhat less clear difference between Type AB and Type O;

Type AB = using both right and left brains simultaneously
Type O  = using both right and left brains alternatively

From these results, it is almost certainly possible to say that "brain activity and blood types are related to each other."
However, it may be a exaggeration to say that blood types and personality are "scientific" grounds. Still, it can be said that it is a powerful experimental result that is one step closer to the truth.

Personality judgment by blood type has deeply penetrated daily life in Japan. It is said that there are places that emphasize on blood type at company recruitment and marriage consultation office. Is blood type and personality scientifically related? Is it only Japanese people to be addicted to blood types so much? I think about the disposition of the Japanese who love typing.

In Japan, psychology is considered as "nonscientific", "humanities" and "friendly" !?

As the image of psychology in here in Japan, "nonscientific", "humanities" and "friendly" factors were promine...
