  Quantum mechanics (QM) has attracted a considerable amount of mysticism, in
public opinion and even among academic researches, due to some of its
conceptually puzzling features, such as the modification of reality by the
observer and entanglement.
  We argue that many popular "quantum paradoxes" stem from a confusion between
mathematical formalism and physics; We demonstrate this by explaining how the
paradoxes go away once a different formalism, usually inconvenient to perform
calculations, is used. we argue that some modern developments, well-studied in
the research literature but generally overlooked by both popular science and
teaching-level literature, make quantum mechanics (that is, "canonical" QM, not
extensions of it) less conceptually problematic than it looks at first sight.
  When all this is looked at together, most "conceptual puzzles" of QM are not
much different from the well-known paradoxes from probability theory.
Consequently, "explanations of QM" involving physical action of consciouses or
an infinity of universes are conceptually unnecessary
