On Clarke's interpretation one defines macroscopically distinguishable (MD) states to be quantum mechanical states which "correspond interpretation is the "unique predecessor rule" which forbids confluences, or evolutions of two or more MD states into a single CI Clarke attaches no interpretation at all to superpositions of MD states. one could measure the spin state of an atom to be v + or v . simply in a mixture of the two spin states v + and v , no interference states since no measuring instrument, ex hypothesi, is placed in the measurement to have evolved from at most one MD state in a mixture. of MD states is always present even after measurement. at the end of the measurement in one or in another of the possible macro-states, S.
