We discuss three consequences of the Baire Category Theorem. In spaces of long-range interactions, typical phase diagrams are trivial. Most ergodic states of a lattice system are not Gibbs states. Unitarily-equivalent self-adjoint operators on Hilbert space with purely discrete spectrum usually can't be added.

Keywords: generic sets,very sparse sets,generic nonGibbsianness,generic lack of self-adjointness properties
