Down the rabbit hole...
Some claim that Bell made a serious mistake and is wrong in his calculations and his conclusions. I have made such arguments and am in process of updating them in "Physics-based Disproof..." and I make another argument in my current essay. Joy Christian also claims that Bell is wrong, for reasons explained in his book and on his blogs. Just today I read a 2011 paper by Hess, De Raedt, and Michielsen on "Hidden Assumptions in the Derivation of the Theorem of Bell". And Ulf Klein's current FQXi essay analyzes the meaning of Bell's conclusions about completeness, and argues that quantum mechanics does not apply to individual events. There are many more such arguments against Bell.
On the other hand, many physicists assume that Bell has banished local reality. That is, reality is non-local and properties don't exist or become real until measurement. Of this 'weirdness' they brag 'we can't possibly understand it' so just "Shut up and calculate!"
To see just how cloud-cuckoo this can become, I call your attention to an Aug 3, 2012 PhysicsWorld article, "Can the future affect the past?" which discusses a new paper by Aharonov et al. based upon weak measurements (as described in my essay). Briefly, "Bell's theorem forbids spin values to exist prior to the final choice of the [EPR] spin-orientation to be measured," and yet the weak measurements [prior to choice] agree with the strong measurements [that 'collapse' the wave function and make the properties "real"].
Get ready. Here it comes:
Aharonov claims that "the only *reasonable* resolution seems to be that ... the weak measurement's outcomes anticipate the experimenter's future choice, even before the experimenters themselves know what their choice is going to be."
Yep, that's "reasonable" in a Bell world.
This is where blind faith in Bell's theorem leads. If this does not constitute de facto proof that Bell mis-analyzed the problem and came to a faulty conclusion, then such proof [as the actual experiments being discussed here] will probably never exist, and physicists will dive deeper and deeper down the rabbit hole.
