That's where correlations of random events and placebo end and where discovery begins. There are 'gods' that are 'better' than others. Even if the principle of what you/people believe goes against what you find scientifically relevent, or factual, or sensible. There still is something to be said about a group of people following a strange set of rules that could be demonstrably better than other sets of rules and bel…

> There are 'gods' that are 'better' than others I don’t think that’s valid. Gods usually come with a set of values or a specific worldview, and these are inherently subjective. You can’t really rank them as "better" or "worse" in any meaningful way. Let’s take an example: imagine I believe in a paperclip-god. The core value here is producing as many paperclips as possible, and I’d argue that anything that doesn’t se…

> Under this belief system, it might be okay to enslave or even kill humans

This is actually what most christians believe (see Abraham's sacrifice). God is the ultimate source of morality, so if God wants you to kill your son - it's the morally good thing to do.

Which shows nicely that morality does not, in fact, come from God or Bible (if it did - we wouldn't care about Isaac - we'd consider it good that he'll get killed by his father). Instead we can't help but feel it's wrong to kill your son.

It's the conflict of the actual "natural law" vs the artificial religious "natural law" nicely wrapped up in one short story.

The OP is low on details. There is more in this article (in french): https://www.lindependant.fr/2025/06/21/il-ny-a-quelle-qui-es... Apparently the ISBT have added this to their list: https://www.isbtweb.org/isbt-working-parties/rcibgt.html (the page still says 47 but the data tables have it added)

Neither article talks about whether this is a minor or a major antigen. Blood for transfusion needs to be crossmatched against antigen types of the recipient. Many patients will tolerate several transfusions of a minor mismatched antigen before developing a sensitivity. Major antigens are what cause significant reactions that can be life-threatening. Minor antigens come into play when crossmatching for infants and pr…

Does the concept of O -ve as a universal donor type apply at all outside of the ABO group, and am I understanding correctly from your comment that even within the APO group O -ve compatibility would still be subject to this antigen matching?

Don't we have synthetic blood, at least capable of transporting oxygen ?

There are 48 blood type systems , of which ABO (giving A, B, AB, and O) and Rh (+/-) can be combined to form the 8 common types. There are effectively millions of types because all the systems combined combinatorially, but most antigens beyond ABO and Rh don't cause that much of an issue, so in emergency cases, they just go with them.

Is that what’s going on with organ matching?

Yes, but even more complicated.

Japanese people are the same, to the point that even anime characters have a blood type.

Yes it's defined for fictional characters, but I have the feeling it's more due to their obsession of details. I've never been asked my blood type there in years, whereas some Taiwanese girls asked me the question.

Oh, they definitely believe in that stuff. Maybe you haven't been asked, but I have, and have been explained how your blood type defines your personality.

There's not really a synthetic oxygen-carrying blood substitute that's commonly used. Turns out it's actually pretty hard to get right. https://en.wikipedia.org/wiki/Blood_substitute has some info on different approaches and products that were/are sometimes used, but the short story is: not really.

Younger generations are now heavily into MBTI. And I mean heavily: you won't find a person under 35 or so who doesn't know their MBTI letters.

I believe that's more of a thing in east asia. I've stumbled upon it only a few times in English speaking media and never here in Sweden. Though people were obsessed with some colour thing a few years back
