All you ever wanted to ask about QBism

A great QBism FAQ appeared yesterday:

For some reason, that link doesn't work for me (security issue). Alternative: http://www.arxiv.org/abs/1810.13401

Until recently, everybody at my institution (Ruđer Bošković Institute in Croatia) had problems with arXiv due to security reasons. Eventually someone from my institution asked arXiv administrators what is going on, and it turned out that arXiv blocked our institution because it looked as if someone from our institution attacked arXiv. Now we are unblocked. Perhaps something similar is going on in your case.

For those who are interested in QBism, a recent text by N. David Mermin might be of interest, too: N. David Mermin, "Making Better Sense of Quantum Mechanics" (https://arxiv.org/abs/1809.01639)

He writes, for example:

"Science starts with mind, the private library of experience for each of us. From the contents of our own experience each of us strives to assemble what that experience means about the world that gives rise to it. An all too common misreading of QBism in the popular scientific press is “It’s all mind”. This is as wrong as the opinion most physicists have about physics, that it’s all world. There is mind and there is a world. Quantum mechanics has taught us that we cannot understand what we are talking about without paying attention to both. What links the contents of my mind to the world that induces them is the meaning I construct for my experience."

There is mind and there is a world. Quantum mechanics has taught us that we cannot understand what we are talking about without paying attention to both.

If that is the message of quantum mechanics, then why can't we see that message already in the macroscopic classical world? Why the importance of the mind is seen only in the microscopic world? QBism doesn't seem to have an answer to that question, which is my main problem with QBism.

It appears to be a different problem. Something about a certificate from lanl not being recognised. It works fine using www instead of lanl at the start of the address.
