Piece of advice: You are loosing grip on reality.
Mercury_01: Either all of us or just you. I'm placing my bet. There're not only four types of personality, dude.
Funny how you base your scientific knowledge is based on popularity, "smartk8t" Real smart.
Just keep doing what you are doing people. See where it gets you in about 10 years. You'll be supplanted so fast it'll make your head spin.
@Mercury_01 & SmartK8t - don't feed the trolls or be one.
If this guy thinks that blood types have an effect on personality than he should write a paper on it and have it peer-reviewed. Just writing a book on something doesn't make it real.
In some pigs, blood type is empirically correlated with hair color. In humans, it may be metabolic/digestive, immune/allergic and neurological/stress-response genetic traits.
According to one study, ABOs tend to release differing levels of hormones to the same stress response (ie, Os - more adrenalin, Bs - more cortisol).
There are also differing rates of mental (and physical) diseases among the types.
While these differences hardly justify a horoscope or cult-like following, they could explain some (very) generalized statistical personality differences when the groups are taken as a whole.
