Summary form only given. We define the premise of "macroscopic local realism" so that its failure is more surprising than failure of the local realism addressed previously. Macroscopic local realism is a premise stating the following. If one can predict the result of a measurement at A by performing a simultaneous measurement on a spatially separated system B, then the result of the measurement at A is predetermined but described by an Einstein-Podolsky-Rosen "element of reality," which has an indeterminacy in each of its possible values, so that only values macroscopically different to those predicted are excluded.
