Description
When data anomalies are observed, it is a common practice to assume some toy models, simplified models, or EFT. In particular one tends to minimize the number of new physical degrees of freedom, as well as the couplings. In this talk, I will describe a number of examples in physics of flavors and dark matter, where this simple-minded approach results in wrong or unphysical results. Based on these observations, I will advocate a few physical conditions that the simplest setup for data analysis has to satisfy in order to avoid this problem.
