So it seems there is predilection in physics to go after simple and elegant models of physical reality. That is, parsimonious models are preferred. Sometimes this means that there is a trade off between mathematical elegance and intuition. For example, if theory A and theory B both perfectly describe a certain phenomenon but A is complex but fits intuition and B is mathematically simple( relies on less assumptions) and elegant but requires breaking intuition, which one is preferred? Are there guidelines for this?
