The European Association of Psychologists’ Associations (EFPA) was created in 1981 as the European Association of Professional Psychologists’ Associations (EFPPA). We show that Shakespeare’s dictum “What’s in a name?” does not apply here and that the loss of the “first P” (the adjectival “professional”) was resisted for almost two decades and experienced by many as a serious loss. We recount some of the deliberations preceding the change and place these in a broader historical context by drawing parallels with similar developments elsewhere. Much of the argument will refer to an underlying controversy between psychology as a science and the practice of psychology, a controversy that is stronger than in most other sciences, but nevertheless needs to be resolved.
