In https://arxiv.org/abs/quant-ph/9810016, Griffiths says the following about his consistent histories interpretation of QM: 1. An experiment can be described in many ways that are equally valid. Each such narration / description is called a consistent family of possible histories. 2. To answer any particular question about the experiment, one has to choose a family of histories that actually helps to answer that question. There may be more than one useful family for a given question. 3. Some consistent families involve MQS (Macroscopic Quantum Superpositions), aka Schroedinger cat states. Now my question is, for any given question, can we be sure of finding a relevant family that DOES NOT involve an MQS?
