It's abstracted at 
and undermines classic realism as well as the explanatory utility of 

"Here we show by both theory and experiment that a broad and rather 
reasonable class of such non-local realistic theories is incompatible 
with experimentally observable quantum correlations. In the 
experiment, we measure previously untested correlations between two 
entangled photons, and show that these correlations violate an 
inequality proposed by Leggett for non-local realistic theories. Our 
result suggests that giving up the concept of locality is not 
sufficient to be consistent with quantum experiments, unless certain 
intuitive features of realism are abandoned."

So, John... in the context of Radin's experiment, your point is?
