Personality pathology is rooted in early development and affects a wide range of affects, behaviours and cognitive processes. Every year thousands of articles about the etiology pf personality pathology are published in various professional or scientific reviews. There is a growing distance between the generalist's practice and our increasingly precise scientific knowledge. However, no one can read everything and therefore, it behoves us to ask ourselves the following questions: is the most recent better than what came before? Is the measurable and demonstrable necessarily clinically interesting? Must what interests the clinician be measured and proved? Whilst theory and clinical research are becoming increasingly precise, innumerable socio-economic forces are pressing for a simplification in clinical practice. "Shrinks" are fashionable! They are everywhere: in the workplace, on television, on the radio.
