Interpretation of quantum mechanics

Quantum mechanics is a physical theory which is extremely non-intuitive. The equations have been very successful in predicting experimental results, but there have been a wide range of interpretations of what those equations mean.

Some of the most common interpretations are summarized here:

Interpretation	Deterministic?	Waveform real?	One Universe?	Avoids hidden variables?	Local?	Avoids collapsing wavefunctions?
Copenhagen interpretation (Waveform not real)	No	No	Yes	Yes	No	Yes
Copenhagen interpretation (Waveform real)	No	Yes	Yes	Yes	No	No
Consistent Histories	No	No	Yes	Yes	No	Yes
Consciousness causes Collapse	No	Yes	Yes	Yes	No	No
Everett many-worlds interpretation	Yes	Yes	No	Yes*	Yes	Yes
Bohm interpretation	Yes	No	Yes	No	No	Yes

^*Many Worlds has no hidden variables, except for the multiple worlds themselves.

Each interpretation has many variants. It is very difficult to get a precise definition of the Copenhagen Interpretation - in the table above, 2 variants of the Copenhagen Interpretation are shown - one that regards the waveform as being a tool for calculating probabilties only, and the other regards the waveform as an "element of reality".
