Copenhagen Interpretation (1927): (1) the Uncertainty Principle [Heisenberg]
and (2) the Principle of Complementarity [Bohr] - wave/particle duality -
loss of propositional logic (3) loss of the Principle of Locality
Rand was mostly referring to (3) "a particle that goes from one place to
another without crossing the places in between." -- actually, quantum
entanglement and loss of "locality" but the problems for realism and the Law
of Indentity is clear in (1) and (2).
For: Bohr, Heisenberg, Pauli and von Neumann
Against: Einstein, Schroedinger, de Broglie, Planck, Bohm, Popper, EPR
Paradox (1935). . . . Ayn Rand . . . without performing a single
experiment.
For/Against: Bell's Inequality (1964)
Experiments on Bell's Theorem (1980's continuing to today)
To say that Rand "was able to conclude that Quantum Mechanics wrong" in
1966 "without performing a single experiment" was to say that Rand was as
smart as Einstein in 1935 who, until his death, maintaining to universal
realism and the Principle of Locality, thought Quantum Mechanics was
"incomplete".
