There are deterministic interpretations of quantum mechanics, under which the usual randomness in quantum mechanics is not truly random.

  But Bell's inequality says that these hidden variable theories are incompatible with the results of experiments. Real experiments. Like these: http://en.wikipedia.org/wiki/Bell_test_experiments http://en.wikipedia.org/wiki/Bell_test_experiments It may be the case that there really is a hidden variable, but it would need to communicate it's value nonlocally, which I'd argue is stranger than the universe just being somewhat random.

    Bell's theorem is based on the assumption of free will, see eg http://en.wikipedia.org/wiki/Superdeterminism http://en.wikipedia.org/wiki/Superdeterminism

      Eeeeh, not quite "free will", but "choices that are not structured relative to the thing being measured", which is a much weaker assumption (though still an assumption).

    The Copenhagen interpretation is arguably the most popular interpretation of quantum mechanics and is nonlocal.
    • ngoldbaum 13y ago
      True, but there are no hidden variables in the copenhagen interpretation.
