  The lately developed part of Quantum Bayesianism named QBism has been
proclaimed by its authors a powerful interpretation of Quantum Physics. This
article presents analysis of some aspects of QBism. The considered examples
show inconsistencies in some basic statements of the discussed interpretation.
In particular, the main quantum mechanical conundrum of measurement and the
observer is, contrary to the claims, not resolved within the framework of
QBism. The conclusion is made that the basic tenets of QBism as applied in
Physics are unsubstantiated.
