I What is the true nature of reality according to quantum mechanics?

[A. Neumaier]

It is quite nice to have a mental image that reflects ordinary things we already understand. QM really misses the boat on a LOT of that. Things are just incredibly weird, when compared to ordinary macroscopic things. And some things that attempt to be analogous, such as "spin" really don't quite match.

QM does tell about reality, but does so in non-intuitive ways, that don't fit our expectations that we generalize from macroscopic experiences.

there must be something we could consider as real, even if we do not understand it, and our failure to understand surely cannot be a guiding rule for physics. Further, if we take expectation values, following Ehrenfest's theorem, it is surely as real as classical physics.

Most of the weirdness of quantum mechanics comes from the way the math is interpreted - namely by putting far too much emphasis on pure states and Born's rule. With my
thermal interpretation of quantum physics, which works in the Ehrenfest picture of quantum mechanics that treats quantum expectations as real, most weirdness is gone.
