*I am not referring to the MWI. I am referring to whether in Schrodinger's cat experiment, the wf of the radioactive source, ( |decayed> + |undecayed> ) , is a superposition of states without interference between its components. If that's the case, perhaps what you would call an "incoherent superposition", then the cat which shares or inherits this wf in Schrodinger's set up, is never in a state of Alive and Dead simultaneously.
