This has no more value than being a "fun fact" (sorry for the word 'fun' in the context of a pandemic and death numbers).. a) it is something you don't have any control b) the diff (odds, bayes factor or any similar definition) is not that great to have an effect on public policy (something like, let's focus our resources on region A, since region B has less risk kind of change)

So, let's all enjoy this study as food for our curiosity, and move on with all the usual measures of social distancing, extra hygiene control and all.. Especially dangerous, if even one crazy person goes out because he has a certain blood type and helps the disease spread

This is how science works. Knowing this may help the production of new theories, that produce new research initiatives, that may result in solutions.

Imagine you are debugging a random connection loss issue in prod. You notice that the errors are much more frequent on server-05.

Ok, fun fact. So what?

What is special about that server? Does it serve customers from a different geographic zone? Is it in another network location?

no, it means type O can do riskier jobs.

Because they have 1/3 less chance of death? Not enough difference to convince me (I'm O+)

[crimsonalucard]

Of course not. But when you're knee deep in the situation and it's time to draw straws it's good to know risk tolerance. (I'm O-).
