Blood Type Personality Theory
I never cared much about blood types, except when its ’bout medical information, much less blood type = personality.
Back at home (Philippines) most people don’t know what blood type they have unless they donate to the Red Cross or need any blood-related emergency. Here in Japan, you need to know cause even during introduction you would be asked about your blood type ( not all the time though ). If you don’t know, they would then see what personality you have and guess your group, most of the time they are correct though
Here is the Japanese Blood Personality Chart
Type A :
Best Traits: Earnest, creative, sensible
Worst Traits: Fastidious, overearnest
Type B:
Best Traits: Wild, a doer, cheerful
Worst Traits: Selfish, irresponsible
Type AB:
Best Traits: cool, controlled, rational
Worst Traits: critical, indecisive
Type O:
Best Traits: Agreeable, sociable, an optimits
Worst Traits: Vain, careless

Ideruは何型ですか?
I find it a silly kind of stereotype though. Japs prefer A’s than B types just because…
I know the history why they do the stereotyping though. Many years ago, a plague struck Japan where most people who succumbed were Type A’s. Type B’s were the least affected. So Type A people were advised to be more hygienic, more serious in all their undertakings healthwise…na evolve to being OC-type and serious at work. B’s became a little bit negligent and fun loving.
