I mean, I suppose I think of most PhD-holding economists as experts on the economy and most PhD-holding Clinical Psychologists as experts on the proper functioning of the human mind, but I don't consider most PhD-holding Social Workers experts at social work, I consider them just basically trained researchers. Ditto for a mathematician or computer scientist who is an expert in only one narrow sliver of their field. Maybe this is because the closer a field is to my own, the easier it is to see the depth of that field.
