Should physicians ignore blood type when giving transfusions?  If, as you imply, there’s absolutely no difference between blood types, then that should be no problem.  If there is a difference, I don’t think anyone here has proved that personality is not influenced by it (not endorsing any such interpretations or superstitions here, just pointing out facts).

Blood type has known physical reality.  I don’t know what the physical expression of all that reality is limited to – but I know it’s real, and can be measured and tested, and can’t be gamed by studying the test questions or pretending to be somebody else.  Meyers-Briggs is a bunch of horse puckey by comparison.

I think the problem here is you might think I’m endorsing these Japanese superstitions about blood type.  I’m not.  I’m saying entirely dismissing the idea that blood type could have effects on the organism at the level of personality is unwise; just like relying on Meyers-Briggs is unwise.  I think truly studying the relationship between blood type and emotions would be interesting.

You think they hire hippies?

The other is random data from a completely unrelated area. 

If I use a set of symptoms to try to trap an error in code that might not be the SOLUTION but it might bring us closer to finding something to solve the error.

Using blood type would be like throwing a dart at it and then saying “that’s it!!! Change that!”

“Eugenics Quarterly became Social Biology in 1969.”

“What’s your bloodtype?”
“Oh, I’m type Q-sidereal.”
“Q-sidereal?”
“Yes, it’s new.  We’re the next stage of human evolution, destined for greatness.  But don’t worry, we’ll be compassionate rulers.  Your lives, such as they are, will go on more or less as they do now.”

I am comforted that there is one level of superstitious idiocy to which America has not yet sunk– Tailoring education to one’s horoscope.

Oh shit, this article just gave some hippie with an early-education degree an idea.

In contrast, blood antigens are a much more accurate and scientific description of something that isn’t even in the same room. You might as well go with birthdays or something.

In the west, none of us know this important info – none of us can give it to the paramedics when they pick us up, unless maybe we’ve given blood and remember what they stamped our card with.

In Japan, even people’s *friends* know what type they are! Even if you’re unconscious, people will know this.

What other emergency info can we make silly fortune telling nonsenses out of, so people remember them?

The “science” of blood-type/personality-type is much broader than Japan. I’ve had friends from Beijing, Hong Kong, and Taipei who say they learn this in school.

And yes, as far as I know, it’s because of one lone quack in the 1970s having wrote a book on it. And in Japan, all a cultural superstition takes to form is one person writing an inflammatory popular book about something that takes hold of public consciousness long enough for people to remember. Not whether it was true or not, people there seem to assume from what I saw that by publishing, the information was somehow deemed true by a publisher.

There are countless diet fad books that can attest to this, like the infamous konyaku diet fad that NEVER GOES AWAY. No matter how many people debunk it.

The more superstitious and religion oriented a culture (and Japan is both extremely superstitious and highly religion oriented by life ceremonies, such as boys days, funerals, birth ceremonies, setsubun, the list goes looooong on), the more I have noticed a tendency for some portion of the population, much like flat-earthers in the west, to always ignore actual scientific debunking and stick to an insane belief.

It’s almost as though a mass-recognized ignorance at one point somehow inoculates a permanent living part of a population against the scientific opposing view of it. Calling their belief factually untrue actually strengthens their acceptance of their original stupidity, much like a disease.

Perhaps this is why religion exists in the modern age.
