Architecture is one of those professions where the more you know the more you know you don't know. Many architects don't know this. There are some who “float” and others who are in a constant state of continuing education. I am reminded of this by the large number of architects who state on their websites “We have always been green” but then you look at their projects with a trained eye and see otherwise. Geothermal heating or solar Photovoltaics on a house with 2 x 6 walls, probably insulated with fiberglass batts is an infraction I commonly see. Those architects who read this and don't see the hyppocracy in this example would be the example of “floaters”
