The two fundamental ‘no go’ theorems for hidden variable reconstructions of the ► quantum statistics, the ► Kochen-Specker theorem  and ► Bell's theorem , can be formulated as results about the impossibility of associating a classical probability space (X,F, P ρ) with a quantum system in the state ρ, when certain constraints are placed on the probability measure P ρ. The Bub-Clifton theorem [2,3], by contrast, is a ‘go’ theorem: a positive result about the possibility of associating a classical probability space with a quantum system in a given state.
