Full Idea
It seems that we can no longer assume that the particle properties we measure necessarily reflect or represent the properties of the particles as they really are.
Gist of Idea
Particle measurements don't seem to reflect their reality

A Reaction
[He cites a 2006 experiment] This gives an interesting response to the Copenhagen Interpretation - that observers appear to be creating the reality they observe, because they only have 'observations', with no reality to correspond to them. I like it.
